|Regulation Under Federal Aviation Administration:  Our Avionics and Aircraft Modifications segments are subject to regulation by the Federal Aviation Administration ("FAA").  We manufacture products and parts under FAA Parts Manufacturing Authority (PMA) requiring qualification and traceability of all materials and vendors used by us.  We make aircraft modifications pursuant to the authority granted by Supplemental Type Certificates issued by the FAA.  We repair aircraft parts pursuant to the authority granted by our FAA Authorized Repair Station.  Violation or changes to FAA regulations could be detrimental to our operation in these business segments.Licensing and Regulation under Federal Indian Law:  Before commencing gaming operations (Class II or Class III) on Indian Land, we must obtain the approval of various regulatory entities.  Gaming on Indian land is extensively regulated by Federal, State, and Tribal governments and authorities.  Regulatory changes could limit or otherwise materially affect the types of gaming that may be conducted on Indian Land.  All aspects of our proposed business operations on Indian Lands are subject to approval, regulation, and oversight by the Bureau of Indian Affairs ("BIA"), the Secretary of the United States Department of the Interior ("Secretary"), and the National Indian Gaming Commission ("NIGC").  Our management of Class III gaming operations is also subject to approval of a Class III Gaming Compact between the Indian Tribe and the respective state.   Failure to comply with applicable laws or regulations, whether Federal, State or Tribal, could result in, among other things, the termination of any management agreements which would have a material adverse effect on us.  Management agreement terms are also regulated by the Indian Gaming Regulatory Act ("IGRA"), which restricts initial terms to five years and management fees to 30% of the net profits of the casino, except in certain circumstances where the term may be extended to seven years and the management fee increased to 40%.  Management agreements with Indian Tribes will not be approved by the NIGC unless, among other things, background checks of the directors and officers of the manager and its ten largest holders of capital stock have been satisfactorily completed.  We will also be required to comply with background checks as specified in Tribal-State Compacts before we can manage gaming operations on Indian land.  Background checks by the NIGC may take up to 180 days and may be extended to 270 days.  There can be no assurance that we would continue to be successful in obtaining the necessary regulatory approvals for our management of proposed gaming operations on a timely basis, or at all.Licensing and Regulation under State Law: Our present and future stockholders are and will continue to be subject to review by regulatory agencies.  Gaming licenses may be required in connection with our proposed management of a State of Kansas owned Lottery Gaming Facility (a casino) and/or a Class III Indian casino on Indian land within the territorial boundaries of the State of Kansas.  Our management personnel, Butler National and/or the managing subsidiaries, the key personnel of all entities, and if applicable the appropriate Indian Tribe may be required to have gaming licenses for Class III gaming and/or a Lottery Gaming Facility gaming licenses in the respective state prior to conducting operations.  The failure of the Company or the key personnel to obtain or retain a state license could have a material adverse effect on the Company or on its ability to obtain or retain Class III licenses in other jurisdictions. Each such State Gaming Agency has broad discretion in granting, renewing and revoking licenses. Obtaining such licenses and approvals will be time consuming and cannot be assured. 
The State of Kansas has approved state owned Lottery Gaming Facilities, pari-mutuel dog and/or horse racing for non-Indian organizations.  The State of Kansas operates a state lottery, keno games, and plans to operate state owned Lottery Gaming Facilities for the benefit of the State.  The Lottery Gaming Facility management contract approval process requires that any entity or person owning one-half of one percent (0.5%) of the ownership interest of the management company must be found suitable to be an owner by the State of Kansas.  Our subsidiary, Butler National Service Corporation, is planned to be the applicant.  However, the State of Kansas has the right to require a finding of suitability for any individuals or entity associated with Butler National Corporation as the parent of Butler National Service Corporation.
There is no assurance that a Lottery Gaming Facility management contract and/or the required state licenses will be awarded to us.  If a Lottery Gaming Facility management contract is not awarded to us, there could be a material adverse effect on our plans to manage a state owned casino in Kansas.  There is no assurance that a Tribal/State Compact between the Tribes and the State of Kansas can be completed.  If the Compact is not approved, there could be a material adverse effect on our plans for management of Class III gaming on Indian lands within the territorial boundaries of Kansas.
As a condition to obtaining and maintaining our Oklahoma Class III license or any other Class III license, we must submit detailed financial and other reports to the Indian Tribe and the respective federal and state regulatory Agencies ("the Agency").  Any person owning or acquiring 5% or more of the Common Stock of the Company must be found suitable by one or more of the agencies or the Indian Tribes ("the Interest").  Any Agency has the authority to require a finding of suitability with respect to any stockholder regardless of the percentage of ownership.  
If found unsuitable by any Agency or the Indian Tribe, the stockholder must offer all of the Ownership Interest in Company stock held by such stockholder to the Company for cash at the current market bid price less a fifteen percent (15%) administrative charge and the Company must purchase such Interest within six months of the offer.  The stockholder is required to pay all costs of investigation with respect to a determination of his/her suitability.  In addition, regardless of ownership, each member of the board of directors and certain officers of the Company are subject to a finding of suitability by any Agency and the Indian Tribe.

|The Aircraft Modifications business derives its ability to modify aircraft from the authority granted to it by the Federal Aviation Administration ("FAA").  The FAA grants this authority by issuing a Supplemental Type Certificate ("STC") after a detailed review of the design, engineering, and functional documentation, and demonstrated flight evaluation of the modified aircraft.  The STC authorizes Avcon to build the required parts and assemblies under FAA Parts Manufacturing Authority ("PMA"), and to make the installations on applicable aircraft.
Avcon owns more than 250 STCs.  When the STC is applicable to a multiple number of aircraft it is categorized as a Multiple-Use STC.  These Multiple-Use STCs are considered a major asset of the Company.  Some of the Multiple-Use STCs include Reduced Vertical Separation Minimums (RVSM), Beechcraft Cargo Door, Beechcraft Extended Door, Learjet AVCON FINS, Learjet Extended Tip Fuel Tanks, Learjet Weight Increase Package, Dassault Falcon 20 Cargo Door, and many special mission modifications.
On May 3, 1996, Avcon received approval from the Federal Aviation Administration for a Multiple-Use Supplemental Type Certificate ("STC") (no. ST00432WI) of its AVCON FIN Modification for installation on Learjet Model 35 and 36 Aircraft.  FAA pilots thoroughly evaluated the test aircraft, and determined that the fins substantially increase the aerodynamic stability in all flight conditions.  The AVCON FIN STC eliminates the operational requirement for Yaw Dampers which are otherwise required in both Learjet models to control adverse yaw tendencies in certain flight conditions, particularly during approach and landing.  Learjets equipped with AVCON FINS exhibit the same aerodynamic stability and improved operating efficiency offered on newer Learjet models, while maintaining the outstanding range, speed, and load-carrying capabilities that made the Learjet Models 35 and 36 among the most popular Business Jets ever produced.  Mounted like the feathers of an arrow on the rear of the aircraft, Learjets equipped with AVCON FINS have a look much the same as the current production aircraft.  This modification will give the Learjets produced in the 1970's and 1980's the look of the 21st century. 
During fiscal year 2002, Avcon made an application to the FAA for the approval of a Multiple-Use STC for the Learjet 20 RX Modification project (including the fins, weight increase, and tip tank extensions) for the Learjet Model 24 and 25 aircraft.  The initial fin STC for the 20 Series is expected in the fall of 2007.
Effective January 2005, the FAA required that all aircraft operating between 29,000 and 41,000 feet within the United States air space be RVSM compliant.  RVSM stands for Reduced Vertical Separation Minimums and means that now aircraft are separated by 1,000 feet vertically instead of the prior 2,000 feet.
During fiscal year 2003, Avcon made an application to the FAA for the approval of the Learjet 20 RVSM MOD (including dual pitot tubes, dual digital altimeters, dual air data computers, autopilot refinements, and a standby altimeter) for the Learjet 20 series aircraft.
In April 2004, the FAA issued a Learjet 20 Series RVSM Group Approval to Avcon for its Supplemental Type Certificate Number ST01195WI.  This is a joint development project with Bizjet of Tulsa, Oklahoma.  Avcon supplies RVSM kits to Bizjet as part of the RVSM joint development project.
During fiscal 2007, Avcon received FAA approval to add the Learjet 30 Series RVSM upgrade modification (including dual pitot tubes, dual digital altimeters, dual air data computers, autopilot refinements, and a standby altimeter) to STC ST01195WI.
Avcon operates an FAA Authorized Repair Station.  The focus of this repair station includes the Learjet model 20 and 30 series, Beechcraft King Air, Cessna turbine engine, Cessna multi-engine piston, and Dassault Falcon 20 aircraft.  The Repair Station is a convenience for our customers bringing aircraft to us for modification and maintenance.  We also use the repair station for maintenance of aircraft purchased for modification and resale.
Aircraft - Acquisition, Modification and Sales
We actively purchase airplanes, through our subsidiary Butler National, Inc., principally Learjets.  Avcon modifies these planes and then we sell them directly to customers or to brokers.  Company owned aircraft are sometimes used to prove the design of the STC modifications during the FAA approval process.  
In fiscal 2006, we purchased three Learjet aircraft.  In November 2004 a Learjet 25 was sold for $424,000.  We sold a Learjet in fiscal 1999 for $2,100,000 and another in fiscal 2002 for $1,425,000.    Butler National, Inc. is currently searching for quality Learjet 20 and 30 series aircraft for modification and resale.  We continue to evaluate the benefits of leasing our aircraft inventory.
Avionics

Classic Aviation Products:  Our mission is to provide and support economical products for older aircraft, often referred to as "Classic" aircraft.  As a result of more than 40 years in the aircraft switching unit business, we recognize the potential to support many aircraft in the last half of their expected service life.  The business mission of the company promotes us as a designer and supplier of "Classic Aviation Products".  A part of the Classic products are directed to supporting safety of flight for the older aircraft.
Butler National Corporation - Tempe, Arizona, manufactures and repairs airborne switching systems for Boeing McDonnell Douglas and their customers.  Switching Units are used to switch the presentation to the flight crew from one radio system to another, from one navigational system to another, and to switch instruments in the aircraft from one set to another.  The Switching Units were designed and have been manufactured since the 1960's to meet Boeing McDonnell Douglas and FAA requirements.  Most Boeing McDonnell Douglas commercial aircraft are equipped with one or more Butler National Switching Units.
Marketing is accomplished directly with Boeing McDonnell Douglas.  Competition is minimal.  However, sales are directly related to the production of Boeing McDonnell Douglas DC-9, DC-10, DC9/80, MD-80, MD-90, MD-11, and KC-10 tanker aircraft.  Avionics provides new replacement units and overhaul service directly to the major airlines using the aircraft manufactured by McDonnell Douglas.
We have in the ordinary course of business received purchase orders from the commercial airlines and aircraft avionics upgrade suppliers for products with scheduled shipment dates into fiscal year 2008.  However, should these customers financially reorganize or for some other reason not accept shipment against these orders, we could suffer significant loss of revenue in the avionics division.Defense Contracting and Electronics:  We supply defense and commercial aviation products to the various agencies of the Department of Defense and the Federal Aviation Administration.   We sell these products directly to the United States and/or to other Department of State approved governments, government contractors, and suppliers.
Engineering design and specialized manufacturing solutions are provided to maintain and update classic military and commercial aviation systems.  In general, we provide our customers the opportunity to update or extend the useful life of products with older components and technology. These products include Gun Control Units (GCU) for the Apache Helicopter and other weapon products, including the Hangfire Override Modules (HOM) for all Boeing derived Chain-Gun® cannons, and various weapon-related firing controls, cabling, and test equipment.  We have upgraded the design of the GCU and expect to expand sales of the Butler National upgraded units to maintain the Apache fleet and other military aircraft.  We have firm sales orders for these products that sometimes have delivery dates more than one year into the future.Boeing 747 Classic Aircraft:  We worked with Honeywell to design the Butler National Transient Suppression Device ("TSD").  The TSD is approved and certified by the Federal Aviation Administration ("FAA") under STC number ST00846SE and is owned, manufactured, and marketed by us.  We sell TSDs to owners and/or operators of Boeing 747 Classic aircraft with a Honeywell Fuel Quantity Indicating System ("FQIS").  The TSD is one solution to the requirements of AD 98-20-40 issued by the FAA to protect the aircraft fuel tanks from hazardous energy levels introduced through the wiring of the FQIS.  As a result of the TWA 800 accident in July 1996, the industry had until November 3, 2001 to comply with AD 98-20-40.  All aircraft returned to service after that date must be in compliance.
There are approximately 400 Boeing 747 Classic aircraft with Honeywell FQIS.  The actual number of aircraft needing our TSD is hard to estimate because a number of these aircraft will be permanently removed from service, a number will have the FQIS system converted from the Honeywell system to a BF Goodrich digital or Smiths digital system, and a number will be protected by a Boeing/BF Goodrich protection device.  We believe that all of the other protection alternatives are more expensive than and not as easy to install as our TSD.
We started shipments of the Butler National Boeing 747 TSD in April 2001.  We continue to provide TSD protection for Boeing 747 Classic aircraft being returned to service.  The FAA required that the TSD be returned to us for inspection after six (6) years or thirty-thousand (30,000) hours in service.  Our first installation was January 2001.  Some units have completed the first inspection.  The majority of these sales are to international customers.Boeing 737 Classic Aircraft:  We designed the Butler National Transient Suppression Device ("TSD") for Boeing 737 Classic Aircraft.  On January 14, 2003, the B737 TSD was approved and certified by the Federal Aviation Administration ("FAA") under STC number ST01160SE.  TSDs are sold to the owners and/or operators of Boeing 737 Classic aircraft with an analog Fuel Quantity Indicating System ("FQIS").  The TSD is one solution to the requirements of AD 99-03-04 issued by the FAA to protect the aircraft fuel tanks from hazardous energy levels introduced through the wiring of the FQIS.  As a result of the TWA 800 accident in July 1996, the industry had until March 9, 2003 to comply with AD 99-03-04.  All aircraft returned to service after that date must be in compliance.
There are approximately 1,000 Boeing 737 Classic aircraft in this market with an analog FQIS.  Estimating the volume of Butler National 737 TSD sales is subject to the same contingencies as described above under the Boeing 747 TSD.  We believe that some of our competitor's protection alternatives are more expensive and not as easy to install as our TSD.
We started shipping the Butler National Boeing 737 TSD in February 2003.  We continue to provide TSD protection for the Boeing 737 Classic aircraft being returned to service.  The FAA required that the TSD be returned to us for inspection after six (6) years or thirty-thousand (30,000) hours in service.SFAR-88, Fuel System Safety:  The FAA issued a Special Federal Aviation Requirement ("SFAR") No. 88 titled "Fuel Tank System Fault Tolerance Evaluation Requirements" applicable to turbine-powered aircraft certified to carry 30 or more passengers or a certified payload capacity of 7,500 pounds or more.  When fully implemented by the FAA, we believe that SFAR-88 may open a market for Butler National designed TSD products to many more aircraft than the Boeing 747 and 737 Classics.  The compliance date for each operator to have a plan for meeting the requirements of the SFAR was December 6, 2002 and has been extended to November 2008.
SFAR-88 requires protection for all systems that might provide an ignition source to the aircraft fuel tank system.  In general, we believe that this requirement may require protective devices on other aircraft parts using electrical power in the fuel system such as fuel pumps, fuel valves, float switches, etc.  To address this market, in July 2001, we applied to the FAA for an STC for a Ground Fault Interruption device ("GFI") for various Boeing aircraft.  We are actively pursuing the completion of the STC.  The Butler National GFI product line will be sensitive to unusual power requirements of the electrical systems related to the fuel system.  We have not completed a full evaluation of the scope and size of this market but our initial estimates are that approximately 100,000 units will be sold to satisfy this requirement.  We believe that there are four or five suppliers for this market.
Gaming
BNSC is engaged in the business of providing management services to Indian tribes in connection with the Indian Gaming Regulatory Act of 1988.  We have three management agreements; however, the performance of these agreements is contingent upon, and subject to approval by the Secretary of Interior, Bureau of Indian Affairs, National Indian Gaming Commission, and the appropriate state, if required.  Also, we have signed consulting engagement letters with two tribes to study and develop plans for Indian gaming.
The "Management Agreement" between the Indian Tribe (the owner and operator) and Butler National Service Corporation (the manager) is the final approval document issued by the National Indian Gaming Commission ("NIGC") before Indian gaming is authorized.  The Management Agreement or Contract is authorized and approved by the NIGC pursuant to the Indian Gaming Regulatory Act of 1988, PL 100-497, 102 Stat. 2467,25 U.S.C. 2701-2721 (sometimes referred to as "IGRA").  Before the Management Agreement is approved by the NIGC, all required contracts with other parties must be approved; including, (a) the compact with the state for Class III gaming, if applicable, (b) compliance with the requirements of the National Environmental Protection Agency ("NEPA"), (c) a Tribal Gaming Ordinance approved by the NIGC, and (d) Indian land ownership or leases, if applicable approved by the Bureau of Indian Affairs ("BIA"). 
The management consulting engagement letters provide for advances of funds to the Indian tribes by BNSC for professional services, fees, licenses, travel, administrative costs, documentation, procedure manuals, purchases of property, equipment, and other costs related to the approval and opening of an establishment.  These advances are considered to be a receivable from the Tribe and to be repaid by the Tribe from the funding to open the enterprise. The ability to collect these advances depends upon the opening of a gaming establishment or by the liquidation of acquired property.  If the collection and/or liquidation efforts are not successful, BNSC may suffer a significant loss of asset value.
Butler National Service Corporation is in the process of obtaining the required licenses for the opening and operation of its potential gaming establishments.  BNSC follows the law and regulations of the Indian Gaming Regulatory Act of 1988 and the state laws as they may apply.  Princess Maria Casino: We have a Management Agreement with the Miami Tribe to provide management services.  On July 9, 1992, the Tribe requested a compact with the State of Kansas for Class III Indian gaming, on Indian land, known as the Maria Christiana Miami Reserve No. 35, located in Miami County, Kansas.  Under the Management Agreement, as approved by the NIGC on January 7, 2000, the Company, as manager, is to receive a 30% share of the profits during the five year term and reimbursement of development costs.  We purchased and currently own an additional 160 acres contiguous to the Indian land providing access.
The Miami Tribe's 1992 compact was the subject of a lawsuit filed in February 1993, in the Federal District Court, by the Miami Tribe, alleging the failure to negotiate a compact in good faith by the State of Kansas.  The United States District Court dismissed the Miami Tribe's suit against the State of Kansas, citing the United States Supreme Court's ruling in Seminole v. State of Florida.  The Supreme Court ruled that the "failure to negotiate" provision of the IGRA did not allow an Indian tribe to compel a state by litigation to negotiate a compact.
In February 1993, then Kansas Governor Finney requested a determination of the suitability of the Miami Indian land for Indian Gaming, under the IGRA, from the Bureau of Indian Affairs (the "BIA").  In May 1994, the NIGC again requested the same determination.  Finally in May 1995, an Associate Solicitor within the BIA issued an opinion letter stating that the Miami Tribe has not established jurisdiction over the Miami land in Kansas.  This was the first definitive statement received from the central office of the BIA in three years.  That opinion was contrary to a September 1994 opinion of the Tulsa Field Solicitor, in an Indian probate, stating that the Miami Tribe has jurisdiction over the Miami Indian land in Kansas.  On July 11, 1995, the U.S. Department of Justice issued a letter to the Associate Solicitor expressing concern about the conclusions reached, based upon the analysis of the case.
The Miami Tribe challenged this opinion in Federal Court.  To prove and protect the sovereignty of the Miami Tribe, and other Indian tribes, relating to their lands, on April 11, 1996, the Court ruled that the Miami Tribe did not have jurisdiction because the BIA had not approved the Tribal membership of the Princess Maria heirs, at the time the management agreement was submitted; therefore, the Court ordered that the NIGC's determination (that Reserve No. 35 is not "Indian land suitable for gaming", pursuant to IGRA) was affirmed.  However, the Court noted in its ruling that nothing precludes the Tribe from resubmitting its management agreement to the NIGC, along with evidence of the current owners' consent, and newly adopted tribal amendments.  On February 22, 1996, the BIA approved the Miami Tribe's constitution and the membership of the heirs.  The Tribe resubmitted the management agreement.  Although the Court noted that the Tribe could resubmit the management agreement, the Court did not pass on whether or not a new submission will obtain approval.
The Tribe resubmitted the management agreement and land question to the NIGC in June 1996.  In July 1996, the NIGC again requested an opinion from the BIA.  On July 23, 1997, the Tribe and the Company were notified that the BIA had again determined that the land was not suitable for gaming, for political policy reasons, without consideration of the membership in the Miami Tribe or recent case law, and the NIGC had to again deny the management agreement.  The Tribe filed a suit in the United States District Court in Kansas City, Kansas.  On May 15, 1998, the Court determined that the land may be suitable for gaming and remanded the case to the NIGC for the documentation.  Therefore, even though the Company and the Tribe believe the BIA and NIGC will agree that the land is "Indian land", and in compliance with all laws and regulations, for a variety of reasons, there is no assurance that the Management Agreement will be approved.  
A lawsuit was filed in the United States District Court for the District of Kansas by the State of Kansas against us, the United States, the Business Committee members of the Miami Tribe and others on October 14, 1999, challenging the determination by the NIGC and the United States District Court for the District of Kansas that the Miami Princess Maria Reserve No. 35 was Indian land.  The State of Kansas requested an order by the Court preventing further development of gaming on the Indian land.
On June 25, 2002, the question in the case was remanded to the NIGC for further review.  All of the defendants believe the determination of Indian land is a power reserved for the United States by the Constitution of the United States.  The NIGC has not made a further determination on the question.  The Miami Tribe expects to eventually receive a favorable determination.
The total advances and investment related to the Princess Maria at April 30, 2007, were $888,802.  This amount is net of a reserve of $1,413,511.Stables Bingo Casino:  We have a signed Management Agreement with the Miami and Modoc Tribes.  A Class III Indian Gaming Compact for a joint venture by the Miami and Modoc Tribes, both of Oklahoma, has been approved by the State of Oklahoma and by the Assistant Secretary, Bureau of Indian Affairs for the U.S. Department of the Interior.  The Compact was published in the Federal Register on February 6, 1996, and is, therefore, deemed effective. The Compact authorizes Class III (Off-Track Betting "OTB") along with Class II (high stakes bingo) at a site within the boundaries of the City of Miami, Oklahoma.  The Stables opened in September 1998.
We are providing consulting and construction management services in the development of the facility and manage the joint-venture operation for the tribes.  The Stables facility was expanded in April 2002 to approximately 30,000 square feet and is located directly south of the Modoc Tribal Headquarters building in Miami, Oklahoma.  The complex contains Class III off-track betting windows, Class III gaming machines, Class III table games, Class III bingo machines, a bar, and a restaurant.  Our Management Agreement was approved by the NIGC on January 14, 1997.  The Oklahoma Class III compact for off-track betting was approved in 1996 and the Oklahoma Class III compact for full casino gaming was approved June 1, 2005.  The Miami and the Modoc Tribes have agreed to amend the agreement to extend the expiration date through September 2013 and to maintain the management fee at 20% of the profits.  At the end of the initial contract term, the Stables had fully paid all advances by Butler National related to the construction of the Stables.  The amendment to the agreement was approved by the NIGC.Shawnee Reserve No. 206:  In 1992, we signed a consulting agreement and have maintained a business relationship with approximately seventy Indian and non-Indian heirs (the "Owners") of the Newton McNeer Shawnee Reserve No. 206 ("Shawnee Reserve No. 206").  This relationship includes advances for assistance in the defense of the property against adverse possession (by one family member) in exchange for being named the manager of any Indian gaming enterprises that may be established on the land.  As a result of our assistance, the Owners are in the process of becoming the undisputed beneficial owners of approximately 72 acres of the Shawnee Reserve No. 206, as ordered by the United States District Court for the District of Kansas.  We purchased and currently own an additional 4 acres contiguous to the Indian land providing access.
Shawnee Reserve No. 206 has been a part of the Shawnee Reservation in Kansas Territory since 1831 and was reserved as Indian land and not a part of the State of Kansas, when Kansas became a state in 1861.  The Indian land is approximately 25 miles southwest from downtown Kansas City, Missouri.
We believe that there may be a significant opportunity for Indian gaming on the Shawnee Reserve No. 206.  No agreements have been approved by the BIA, or the NIGC, or any other regulatory authority.  There can be no assurance that these or future agreements will be approved nor that any Indian gaming will ever be established on the Shawnee Reserve, or that we will be the Management Company.
The total advances and investment related to Shawnee Reserve No. 206 at April 30, 2007, was $805,248.  This amount is net of a reserve of $1,049,222.Modoc Casino:  We signed a consulting agreement with the Modoc Tribe on April 21, 1993.  As a part of this project, we have a management agreement with the Modoc Tribe to construct and operate an Indian gaming facility on Modoc Reservation lands in Eastern Oklahoma.  The Management Agreement was filed with the NIGC on June 7, 1994 for review and approved on July 11, 1997.  The Tribe and the Company have not determined a schedule for this project.
The total advances and investment related to the Modoc Tribe at April 30, 2007, was $112,501.  This amount is net of a reserve of $373,271.Associated risks:The associated risk of Indian gaming is that a management agreement may not be approved and that the liquidation of the assets may not recover enough funds to cover our advances.  We have been involved in this business since 1991 and have experienced significant project slow downs and holds but have not had any project terminate by the federal courts or regulatory agencies.  All Management Agreements submitted for approval have been approved by the NIGC.  There can be no assurance that current management agreements will continue in force, future management agreements will be approved and that the U.S. Congress will not outlaw Indian gaming.  Should any of these events occur, we would choose alternative uses of the Indian land in cooperation with the Tribes to recover the advances.  There is no assurance that all of the advances could be recovered.Kansas Owned Gaming (KOG):In March of 2007 Kansas passed Senate Bill 66 for state-owned gaming in Kansas.  The bill provides for state-owned casinos in at least four locations across Kansas.  These locations include Ford County, Wyandotte County, Crawford or Cherokee County, and Sedgwick or Sumner County.  State sponsored studies report that the implementation of this legislation could result in approximately $200 million annually to the State of Kansas.  
This positive action by the Kansas Legislature could provide substantial tourism revenue especially in destinations like historic Boot Hill in Ford County and the booming economic development in Western Wyandotte County.
On March 15, 2007, Boot Hill Gaming, representing Dodge City, Kansas announced that Butler National Service Corporation of Olathe, Kansas had been selected to make application to the State of Kansas to be the casino manager for the Boot Hill Destination Casino.  Butler National has been assisting Dodge City and Boot Hill Gaming with research, development plans, financial projections, design, and promotion of a Destination Casino at Dodge City with an All-Kansas Team.
Boot Hill Gaming, Inc. is a Dodge City community organization consisting of community volunteers of City of Dodge City, Ford County, Kansas, and many volunteer citizen support groups with the purpose of assembling an All-Kansas Team to develop a gaming establishment to enhance and recreate the world famous 1870's experience at a historic Boot Hill Destination in Dodge City.
There is no assurance that Butler National will be awarded a contract to manage a state-owned facility for Kansas.  Senate Bill 66 provides for a fairly complex applicant review and selection process by the State of Kansas.  Butler National plans to use its best efforts to acquire rights to manage a gaming facility on behalf of the State of Kansas.

BNS contracts with government and private owners of water and wastewater pumping stations to provide both monitoring and preventive maintenance services for our customers.  A high percentage of BNS business comes from municipally owned pumping stations.  BNS is currently soliciting business only in Florida.  While we have exposure to competitive forces in the monitoring and preventive maintenance business, management believes the competition is limited in the Florida area.
Corporate
Corporate / Professional Services:  We provide licensed architectural services through BCS Design, Inc.  These services include commercial and industrial building design.  We have expanded this segment to include aviation-related engineering consulting services and operate as the Butler National Aircraft Certification Center.
Through BCS Design, Inc. we are developing, for sale, single family housing units in Junction City, Kansas.  The city is adjacent to the U.S. Army post at Fort Riley, Kansas.  Construction started on eight units in July 2006.  At April 30, 2007 the eight townhouse units were over 80% completed.  Land has been purchased for an additional thirteen units.  The estimated selling price for these units is $150,000 to $180,000.    Patents and Trademarks:  We have no patents, trademarks, licenses, franchises, or concessions that need to be held to do business other than the FAA, PMA, and Repair Station licenses.  We maintain certain airframe alteration certificates, commonly referred to as Supplemental Type Certificates ("STC's"), issued to us by the FAA, for the Aircraft Modification and Avionics businesses.  The STC, PMA, and Repair Station licenses are not patents or trademarks.  The FAA will issue an STC to anyone, provided that the person or entity documents and demonstrates to the FAA that a change to an aircraft configuration does not endanger the safety of flight.  The PMA and Repair Station licenses are available to any person or entity, provided that the person or entity maintains the appropriate documentation and follows the appropriate manufacturing, repair and/or service procedures.  The FAA requires the aircraft owner to have the STC document in the aircraft log after each modification is complete.Seasonality:  Our business is generally not seasonal.Customer Arrangements:  Most of our products are custom-made.  Except in isolated situations no special inventory-storage arrangements, merchandise return and allowance policies, or extended payment practices are involved in our business.  We are not dependent upon any single customer except for Switching Units and defense products.  Switching Units are sold to various Boeing McDonnell Douglas and Douglas Aircraft Company customers.  
We require deposits from our customers for aircraft modifications.  We generally collect full payment for services before the modified aircraft are released.  Long term projects, such as cargo door modifications, require interim payments from the customer.
|Backlog:  Our backlog as of April 30, 2007, 2006, and 2005, was as follows:







                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
|Our backlog as of July 2, 2007 totaled $11,791,645; consisting of $5,037,895, $4,374,679, $2,226,710, and $152,361 respectively, for Aircraft Modifications, Avionics, Monitoring Services, and Corporate / Professional Services  The backlog includes firm pending and contract orders, which may not be completed within the next fiscal year.  The backlog includes orders to be delivered after fiscal year 2008 in the amount of $2,609,388.  This is standard for the industry in which modifications services and related contracts may take several months or years to complete.  Such actions force backlog as additional customers request modifications, but must wait for other projects to be completed.  There can be no assurance that all orders will be completed or that some may ever commence.Employees:  We employed 88 employees on April 30, 2007 compared to 82 employees on April 30, 2006, and 94 employees on April 30, 2005. As of July 2, 2007, 87 people were employed.  None of our employees are subject to any collective bargaining agreements.Financial Information about Foreign and Domestic Operations, and Export Sales:Information with respect to Domestic Operations may be found at Note 10 of Notes to Consolidated Financial Statements.  International sales are made through authorized installation centers and direct to foreign customers to be completed and included in domestic operations.  The export sales consisted of approximately $677,109 in 2007, $973,000 in 2006, and $140,000 in 2005.Item 1A.  RISK FACTORS Factors That May Affect Future Results of Operations, Financial Condition or Business:Statements made in this report, the Annual Report on Form 10-K the Annual Report to Stockholders in which this report is made a part, other reports and proxy statements filed with the Securities and Exchange Commission, communications to stockholders, press releases, and oral statements made by representatives of the Company that are not historical in nature, or that state the Company's or management's intentions, hopes, beliefs, expectations or predictions of the future, may constitute "forward-looking statements" within the meaning of Section 21E of the Securities and Exchange Act of 1934, as amended (the "Exchange Act"). Forward-looking statements can often be identified by the use of forward-looking terminology, such as "could," "should," "will," "intended," "continue," "believe," "may," "expect," "hope," "anticipate," "goal," "forecast," "plan," "guidance" or "estimate" or the negative of these words, variations thereof or similar expressions. Forward-looking statements are not guarantees of future performance or results. They involve risks, uncertainties, and assumptions. It is important to note that any such performance and actual results, financial condition or business, could differ materially from those expressed in such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in this Item 1A. Risk Factors and elsewhere herein or in other reports filed with the SEC. Other unforeseen factors not identified herein could also have such an effect. We undertake no obligation to update or revise forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes in future operating results, financial condition or business over time.  General Governmental Regulations of Financial Reporting:  The Company reports information to its stockholders and the general public pursuant to the regulations of various Federal and State Commissions and Agencies.  These regulations require conformance by the Company to Generally Accepted Accounting Principles, to pronouncements of the Financial Accounting Standards Board, and to accounting and reporting directives issued by the commissions and agencies.  The political and regulatory environment in which the Company is operating is dynamic and rapidly changing.  Adoption and/or changes in regulations defining accounting procedures or reporting requirements could have a materially adverse effect on the Company.  The Company depends upon the financial institutions and capital markets for financing to continue operations and to finance and develop new opportunities.General Governmental Regulation of Gaming:  Operations - The Company's approved and proposed gaming management operations are and will be subject to extensive gaming laws and regulations, many of which were recently adopted and have not been the subject of definitive interpretations and are still subject to proposed amendments and regulation.  The political and regulatory environment in which the Company is and will be operating, with respect to gaming activities on both non-Indian and Indian land, is dynamic and rapidly changing.  Adoption and/or changes in gaming laws and regulations could have a materially adverse effect on the Company.  Interference with the execution of the steps defined by the gaming laws and regulations by interested third parties, although not included by the regulations, may significantly slow the approval process.Fuel and Energy Costs: Our business depends on use of the aircraft for business transportation, freight transportation, and many special mission applications.  Should our customers be unable to purchase fuel and energy and/or be unable to pass on disproportionate costs to their customers, the use of business and military aircraft by our customers may be curtailed.  The value of the aircraft related assets would decrease and the revenues related to the aircraft equipment and modifications would decrease.  These events could have a material adverse effect on our Company.Key Personnel:  The Company's inability to retain key personnel may be critical to the Company's ability to achieve its objectives.  Key personnel are particularly important in maintaining relationships with Indian Tribes and with the operations licensed by the FAA.  Loss of any such personnel could have a materially adverse effect on the Company.
We are highly dependent upon our CEO and President, qualified executives, key electrical, mechanical, and structural engineers, technical staff, sales and marketing representatives, financial and administrative staff and production personnel.  The loss of these key persons, whose knowledge, leadership and technical expertise upon which we rely, would harm our ability to execute our business plan.
Our success depends heavily upon the continued contributions of these key persons, whose knowledge, leadership and technical expertise would be difficult to replace, and on our ability to attract and retain experienced professional staff.  We entered into an employment agreement with our CEO; however, we do not maintain key person insurance on any of these key persons.  If we were to lose the services of these key persons, our ability to execute our business plan would be harmed and we may be forced to cease operations until such time as we could hire suitable replacements.Competition:Increased competition, including the entry of new competitors, the introduction of new products by new and existing competitors, or price competition, could have a materially adverse effect on the Company. Additionally, because of the rapid rate at which the gaming industry has expanded, and continues to expand, the gaming industry may be at risk of market saturation, both as to specific areas and generally.  Overbuilding of gaming facilities at particular sites chosen by the Company may have a material adverse effect on the Company's ability to compete and on the Company's operations. Major Customers:The termination of contracts with major customers or renegotiation of these contracts at less cost-effective terms, could have a materially adverse effect on the Company.  Irregularities in financial accounting procedures, financial reporting requirements and regulatory reporting requirements could cause major customers to become unstable and be unable to complete business transactions which could have a materially adverse effect on the Company.Product Development:Difficulties or delays in the development, production, testing and marketing of products, could have a materially adverse effect on the Company.  The Company's aviation business is subject, in part, to regulatory procedures and administration enacted by and/or administered by the FAA.  Accordingly, the Company's business may be adversely affected in the event the Company is unable to comply with such regulations relative to its current products and/or if any new products and/or services to be offered by the Company can or may not be formally approved by such agency.  Moreover, the Company's proposed new aviation modification products will depend upon the issuance by the FAA of a Supplemental Type Certificate with related parts manufacturing authority and repair station license, the issuance of which no assurances can be given.Adverse Actions:Adverse actions by regulators, customers, competitors and/or professionals engaged to regulate or to serve the Company may cause project delays and excessive administrative costs not controllable by the Company.Administrative Expenditures:Higher service, administrative, additional regulatory requirements, or general expenses occasioned by the need for additional legal, consulting, advertising, marketing, or administrative expenditures may decrease income to be recognized by the Company.Low-Priced Penny Stock:  Because our common stock is deemed a low-priced "Penny" stock, an investment in our common stock should be considered high risk and subject to marketability restrictions.
Since our common stock is a penny stock, as defined in Rule 3a51-1 under the Securities Exchange Act, it will be more difficult for investors to liquidate their investment even if and when a market develops for the common stock.  Until the trading price of the common stock rises above $5.00 per share, if ever, trading in the common stock is subject to the penny stock rules of the Securities Exchange Act specified in rules 15g-1 through 15g-10.  Those rules require broker-dealers, before effecting transactions in any penny stock, to:

Deliver to the customer, and obtain a written receipt for, a disclosure document;
Disclose certain price information about the stock;
Disclose the amount of compensation received by the broker-dealer or any associated person of the broker-dealer;
Send monthly statements to customers with market and price information about the penny stock; and
In some circumstances, approve the purchaser's account under certain standards and deliver written statements to the customer with information specified in the rules.Consequently, the penny stock rules may restrict the ability or willingness of broker-dealers to sell the common stock and may affect the ability of holders to sell their common stock in the secondary market and the price at which such holders can sell any such securities.  These additional procedures could also limit our ability to raise additional capital in the future.
In addition, some provisions of our Articles of Incorporation and Bylaws could make it more difficult for a potential acquirer to acquire a majority of our outstanding voting stock. This includes, but is not limited to, provisions that: provide for a classified board of directors, prohibit stockholders from taking action by written consent, and restrict the ability of stockholders to call special meetings. We are also subject to provisions of Kansas law that prohibit us from engaging in any business combination with any interested stockholder for a period of three years from the date the person became an interested stockholder, unless certain conditions are met, which could have the effect of delaying or preventing a change of control. 
Regulation Under Federal Aviation Administration:  Our Avionics and Aircraft Modifications segments are subject to regulation by the Federal Aviation Administration ("FAA").  We manufacture products and parts under FAA Parts Manufacturing Authority (PMA) requiring qualification and traceability of all materials and vendors used by us.  We make aircraft modifications pursuant to the authority granted by Supplemental Type Certificates issued by the FAA.  We repair aircraft parts pursuant to the authority granted by our FAA Authorized Repair Station.  Violation or changes to FAA regulations could be detrimental to our operation in these business segments.Licensing and Regulation under Federal Indian Law:  Before commencing gaming operations (Class II or Class III) on Indian Land, we must obtain the approval of various regulatory entities.  Gaming on Indian land is extensively regulated by Federal, State, and Tribal governments and authorities.  Regulatory changes could limit or otherwise materially affect the types of gaming that may be conducted on Indian Land.  All aspects of our proposed business operations on Indian Lands are subject to approval, regulation, and oversight by the Bureau of Indian Affairs ("BIA"), the Secretary of the United States Department of the Interior ("Secretary"), and the National Indian Gaming Commission ("NIGC").  Our management of Class III gaming operations is also subject to approval of a Class III Gaming Compact between the Indian Tribe and the respective state.   Failure to comply with applicable laws or regulations, whether Federal, State or Tribal, could result in, among other things, the termination of any management agreements which would have a material adverse effect on us.  Management agreement terms are also regulated by the Indian Gaming Regulatory Act ("IGRA"), which restricts initial terms to five years and management fees to 30% of the net profits of the casino, except in certain circumstances where the term may be extended to seven years and the management fee increased to 40%.  Management agreements with Indian Tribes will not be approved by the NIGC unless, among other things, background checks of the directors and officers of the manager and its ten largest holders of capital stock have been satisfactorily completed.  We will also be required to comply with background checks as specified in Tribal-State Compacts before we can manage gaming operations on Indian land.  Background checks by the NIGC may take up to 180 days and may be extended to 270 days.  There can be no assurance that we would continue to be successful in obtaining the necessary regulatory approvals for our proposed gaming operations on a timely basis, or at all.Licensing and Regulation under State Law: Our present and future stockholders are and will continue to be subject to review by regulatory agencies.  Gaming licenses may be required in connection with our proposed management of a State of Kansas owned Lottery Gaming Facility (a casino) and/or a Class III Indian casino on Indian land within the territorial boundaries of the State of Kansas.  Our management personnel, Butler National and/or the managing subsidiaries, the key personnel of all entities and if applicable the appropriate Indian Tribe may be required to have gaming licenses for Class III gaming and/or a Lottery Gaming Facility gaming licenses in the respective state prior to conducting operations.  The failure of the Company or the key personnel to obtain or retain a license could have a material adverse effect on the Company or on its ability to obtain or retain Class III licenses in other jurisdictions. Each such State Gaming Agency has broad discretion in granting, renewing, and revoking licenses. Obtaining such licenses and approvals will be time consuming and cannot be assured. 
The State of Kansas has approved state owned Lottery Gaming Facilities, pari-mutuel dog and/or horse racing for non-Indian organizations.  The State of Kansas operates a state lottery, keno games, and plans to operate state owned Lottery Gaming Facilities for the benefit of the State.  The Lottery Gaming Facility management contract approval process requires that any entity or person owning one-half of one percent (0.5%) of the ownership interest of the management company must be found suitable to be an owner by the State of Kansas.  Our subsidiary, Butler National Service Corporation, is planned to be the applicant.  However, the State of Kansas has the right to require a finding of suitability for any individuals or entity associated with Butler National Corporation as the parent of Butler National Service Corporation.
There is no assurance that a Lottery Gaming Facility management contract and/or the required state licenses will be awarded to us.  If a Lottery Gaming Facility management contract is not awarded to us, there could be a material adverse effect on our plans to manage a state owned casino in Kansas.  There is no assurance that a Tribal/State Compact between the Tribes and the State of Kansas can be completed.  If the Compact is not approved, there could be a material adverse effect on our plans for management of Class III gaming on Indian lands within the territorial boundaries of Kansas.
As a condition to obtaining and maintaining our Oklahoma Class III license or any other Class III license, we must submit detailed financial and other reports to the Indian Tribe and the respective federal and state regulatory Agencies ("the Agency").  Any person owning or acquiring 5% or more of the Common Stock of the Company must be found suitable by one or more of the agencies or the Indian Tribes ("the Interest").  Any Agency has the authority to require a finding of suitability with respect to any stockholder regardless of the percentage of ownership.  If found unsuitable by any Agency or the Indian Tribe, the stockholder must offer all of the Ownership Interest in Company stock held by such stockholder to the Company for cash at the current market bid price less a fifteen percent (15%) administrative charge and the Company must purchase such Interest within ten days of the offer.  The stockholder is required to pay all costs of investigation with respect to a determination of his/her suitability.  In addition, regardless of ownership, each member of the board of directors and certain officers of the Company are subject to a finding of suitability by any Agency and the Indian Tribe.

|A lawsuit was filed in the United States District Court for the District of Kansas by the State of Kansas against us, the United States, the Business Committee members of the Miami Tribe and others on October 14, 1999, challenging the determination by the NIGC and the United States District Court for the District of Kansas that the Miami Princess Maria Reserve No. 35 is Indian Land for the purposes of gaming under the Indian Gaming Regulatory Act.  The State of Kansas requested an order by the Court preventing further development of gaming on the Indian land.
The question in the case has been remanded to the NIGC for further review.  The BIA has issued a negative opinion concerning jurisdiction over the land.  An interim lawsuit was filed to protect rights related to the opinion and the federal court of appeals dismissed the lawsuit as premature.  The NIGC has not made a further determination on the question.  The Miami Tribe expects to eventually receive a favorable determination.  We cannot reliably predict the outcome of the case.
Our subsidiary, Avcon Industries, received a complaint from the Kansas Human Rights Commission filed by a former employee alleging that he was involved in a work-related injury and further alleging he was terminated from his employment because of his race, age, and alleged disability.  Avcon denies that the employee was dismissed and the allegations.  Avcon will vigorously defend against the allegations.We cannot reliably predict the outcome of this dispute.
Our subsidiary, BCS Design Inc. has asserted claims against Poole Leasing Solutions, LLC for breaches of contract related to BCS design and construction of an office building.  Poole contends it is entitled to withhold the payments that are past due to BCS in the amount of $21,178.74. The Poole's have demanded Arbitration and alleged damages of approximately $431,000.00.  BCS is vigorously defending the Poole claims. We are not able at this time to reliably predict the outcome of the dispute.As of July 2, 2007, there are no other significant known legal proceedings pending against us.  We consider all such unknown proceedings, if any, to be ordinary litigation incident to the character of the business.  We believe that the resolution of any claims will not, individually or in the aggregate, have a material adverse effect on the financial position, results of operations, or liquidity of the Company.

|Our sales for fiscal 2007 were $14,681,042, a decrease of 4.1% from fiscal 2006 sales of $15,307,127.  We experienced a 63.8% increase in earnings before taxes from fiscal 2006 to fiscal 2007.  Our operating profit for 2007 was $1,251,330, compared to $936,879 in 2006, an increase of 33.6%.  Discussion of specific changes by segment are as follows.Aircraft Modifications:  Sales from the Aircraft Modifications including modified aircraft decreased 11.7% from $7,580,980 in fiscal 2006, to $6,696,737 in 2007.  The modifications segment had an operating loss of $227,368 in 2007, compared to a loss of $303,064 in 2006.  Avcon RVSM sales decreased by approximately $553,000.  Revenues generated from other modification services decreased $330,886 in fiscal 2007.  
We believe we may sell and install approximately 25 to 50 Lear 20 & 30 series RVSM kits during the next two years.  In addition to the RVSM sales, we expect to experience some increase in our base modification sales.  As the economy grows aircraft owners may elect to update, modify, and purchase business aircraft.  A shift to business aircraft ownership positively impacts our aircraft modification revenues.  Although we cannot anticipate the future we must always consider the negative impact of items such as the 9-11 event, increases in fuel prices, and general economic downturns.Aircraft Acquisitions and Sales:  There were no aircraft sales in fiscal 2007 or fiscal 2006.  We acquired no aircraft during fiscal 2007.  Management expects this business segment to have increased sales in the next year.  FAA required modifications to the business aircraft fleet may increase customer demand for company owned aircraft.  Avionics:  Sales from Avionics increased 22.3%, from $2,894,086 in fiscal 2006, to $3,538,422 in fiscal 2007.  This increase is directly related to sales of defense products.  Operating profits decreased from $292,761 in fiscal 2006 to $286,995 in fiscal 2007.  The 2% decrease in operating profit is related to additional material cost, material spoilage, additional labor requirements, and rework labor costs on a major lower margin "build-to-print" contract.  Further additional costs from this contract may be experienced in fiscal 2008.  Management expects this business segment to significantly increase in future years due to the addition of new fuel system protection devices like the TSD, GFI, and other classic aviation defense products.Services - SCADA Systems and Monitoring Services:  Revenue from Monitoring Services increased from $1,440,400 in fiscal 2006 to $2,403,065 in fiscal 2007, an increase of 66.8%.  During fiscal 2007, we maintained a relatively level volume of long-term contracts with municipalities.  We had increased revenue due to a significant contract for the rehabilitation of city lift stations.  We anticipate the revenues from additional lift station rehabilitations to continue for the next few years.   Revenue fluctuates due to the introduction of new products and services and the related installations of these types of products.  Our contracts with our two largest customers have been renewed through fiscal 2008.  An operating profit of $185,736 in Monitoring Services was recorded in fiscal 2007, compared to a fiscal 2006 profit of $134,109 an increase of 38.5%.  We believe the service business has had revenue stability over the past few years and we expect this to continue.

|Gaming:  Revenues from management services related to gaming increased 29.1% from $1,292,222 in fiscal 2006, to $1,668,227 in fiscal 2007.  We believe the increase is related to the approval of Class III casino gaming in Oklahoma.
We have advanced and invested a total of $4,718,991 in Indian gaming developments.  We have reserves of $2,912,440, at April 30, 2007 and at April 30, 2006.  Based on the information available to us we believe that our advances for Indian gaming developments will be totally reimbursed as casinos are opened.  Due to the fact that all of the proposed casinos are involved in legal and governmental actions whose outcome is not certain nor is there any time frame for resolution we believe it is necessary to establish reserves against the advances.  The reserve amount is an estimate of the value we would receive if Tribal casinos were not opened and we were forced to liquidate the assets that we have acquired with our advances.  These assets were intended to be used with Tribal casinos and consist of the purchase of land and land improvements.  The land purchases are located adjacent to residential developments.  We believe that these tracts could be developed and sold for residential and commercial use to recover advances if the gaming enterprises do not open. 
In the years ended April 30, 2006 through 2007 there has been no change in reserves.  We determine annually the amount of any increase in reserves based on our determination of the fair value of assets acquired by our advances for Indian developments.

|Selling General and AdministrativeExpenses were $3,795,772, or 25.8% of revenue, in fiscal 2007, and $3,517,125, or 23.0% of revenue in fiscal 2006.  Sales, General and Administrative costs increased by approximately $279,000 in fiscal 2007 compared to fiscal year 2006.  During fiscal 2007 we reduced expenses related to gaming by approximately $85,000.  We anticipate using these savings in fiscal 2008 to promote gaming in Kansas.  Last year we reduced the aircraft and promotional expenses by $525,000, however this year we began a campaign to increase sales at our avionics and architectural division which increased their fiscal 2007 travel and promotional expenses by approximately $194,000.  Aircraft carrying cost for the company increased by slightly over $87,000 due to increased insurance costs and required maintenance of the aircraft.  We experienced an increase related to building and occupancy expenses of approximately $150,000.  Five percent of the increase in occupancy expenses were related to utility costs.  Throughout the year we were able to reduce our overall personnel costs by $37,000.  This reduction was attributed primarily to management's decision to control our insurance cost through the self funded Butler National Corporation Employee Health Care Plan.
In an effort to control our insurance costs and maintain quality health care coverage for our employees, our health insurance policy became self funded on April 1, 2006 as the Butler National Corporation Employee Health Care Plan.  The Plan has contracted with a managed care network of medical providers whose members have agreed to charge the Plan reduced or discounted charges for covered services provided to our employees and their families.  Although our employees have the freedom to choose to receive care from any Physician, Hospital or other medical care provider, as a general rule the amount or percentage of an otherwise covered expense payable by the Plan will vary, depending on whether the provider from whom the employee receives care is a member of the Plan's PPO network(s).  Generally, the Plan will pay a higher percentage of a covered expense if the care is received by a network provider.  The Plan Document, through a third party administrator controls all determinations related to coverage.  
As sales and our employment continue to grow we would anticipate overhead expenses to increase.  We continue to monitor and evaluate our overhead expenses in order to efficiently manage our operations.
Other Income (Expense)

|Fiscal 2006 compared to Fiscal 2005
Our sales for fiscal 2006 were $15,307,127, a decrease of 35% from fiscal 2005 sales of $23,389,587.  Our operating profit for 2006 was $936,879, compared to $2,794,034 in 2005.  Discussion of specific changes by segment are as follows.Aircraft Modifications:  Sales from the Aircraft Modifications including modified aircraft decreased 55% from $16,494,103 in fiscal 2005, to $7,580,980 in 2006.  The modifications segment had an operating loss of $303,064 in 2006, compared to income of $2,267,433 in 2005.  Avcon RVSM sales decreased by approximately $10,700,000.  Revenues generated from other modification services increased $2,614,237 in fiscal 2006.  Approval of our application to add additional aircraft models to our RVSM STC has been delayed six to twelve months due to FAA staff availability and a lack of funding to the FAA.  Avcon maintained the trained RVSM production staff in anticipation of the Lear 30 series RVSM approval by the FAA throughout most of the year.    
We believe we will sell and install approximately 50 to 100 Lear 20 & 30 series RVSM kits during the next two years.  In addition to the RVSM sales, we expect to experience some increase in our base modification sales.  As the economy grows aircraft owners may elect to update, modify, and purchase business aircraft.  A shift to business aircraft ownership positively impacts our aircraft modification revenues.  Although we cannot anticipate the future we must always consider the negative impact of items such as the 9-11 event, increases in fuel prices, and general economic downturns.Aircraft Acquisitions and Sales:  There were no aircraft sales in fiscal 2006.  Aircraft sales in fiscal 2005 accounted for $457,876 in revenues.  Operating profits were $70,482 in fiscal 2005.  We acquired three aircraft during fiscal 2006.  Management expects this business segment to increase in future years due to increased aircraft acquisitions, modifications, and resale's.  FAA required modifications to the business aircraft fleet may increase customer demand for company owned aircraft.Avionics:  Sales from the Avionics decreased 5.4%, from $3,057,784 in fiscal 2005, to $2,894,086 in fiscal 2006.  This decrease is directly related to sales of defense products.  Operating profits increased from a $143,332 loss in fiscal 2005 to income of $292,761 in fiscal 2006.  This increase in profit was a direct result of a reduction in research and development costs.  Management expects this business segment to significantly increase in future years due to the addition of new fuel system protection devices like the TSD, GFI, and other classic aviation defense products.Services - SCADA Systems and Monitoring Services:  Revenue from Monitoring Services increased from $1,220,679 in fiscal 2005 to $1,440,400 in fiscal 2006, an increase of 18%.  During fiscal 2006, we maintained a relatively level volume of long-term contracts with municipalities.  We had increased revenue due to significant hurricane activity during fiscal 2006.  Revenue fluctuates due to the introduction of new products and services and the related installations of these types of products.  Our contracts with our two largest customers have been renewed for fiscal 2007.  An operating profit of $134,109 in Monitoring Services was recorded in fiscal 2006, compared to a fiscal 2005 profit of $13,937.  We believe the service business has had revenue stability over the past few years and we expect this to continue.

|Gaming:  Revenues from management services related to gaming increased 18.1% from $1,094,039 in fiscal 2005, to $1,292,222 in fiscal 2006.  The increase is related to the approval of Class III casino gaming in Oklahoma.
We have advanced and invested a total of $4,718,991 in Indian gaming developments.  We have reserves of $2,912,440, at April 30, 2006 and $2,912,440 at April 30, 2005.  Based on the information available to us we believe that our advances for Indian gaming developments will be totally reimbursed as casinos are opened.  Due to the fact that all of the proposed casinos are involved in legal and governmental actions whose outcome is not certain nor is there any time frame for resolution we believe it is necessary to establish reserves against the advances.  The reserve amount is an estimate of the value we would receive if Tribal casinos were not opened and we were forced to liquidate the assets that we have acquired with our advances.  These assets were intended to be used with Tribal casinos and consist of the purchase of land and land improvements.  The land purchases are located adjacent to residential developments.  We believe that these tracts could be developed and sold for residential and commercial use to recover advances if the gaming enterprises do not open. 
In the years ended April 30, 2004 through 2006 there has been no change in reserves.  We determine annually the amount of any increase in reserves based on our determination of the fair value of assets acquired by our advances for Indian developments.

|Selling General and AdministrativeExpenses were $3,517,125, or 23.0% of revenues, in fiscal 2006, and $4,161,755, or 17.8% of revenue in fiscal 2005.  Sales, General and Administrative costs were reduced by approximately $645,000 in fiscal year 2006 compared to fiscal year 2005.  During fiscal year 2006, we reduced the level of legal expenditures related to Indian and Kansas Owned Gaming by approximately $281,000.  As a result of the decline in sales activity and increased fuel costs, we reduced our aircraft and auto expenses related to sales promotion and administration by approximately $525,000.  Smaller decreases were made in employee relations $15,000 and office expenses $35,000.  We increased personnel costs related to our engineering staff performance incentive pay by approximately $155,000 and regulatory compliance requirements costs for professional service and travel cost by approximately $84,000.
In an effort to control our insurance costs and maintain quality health care coverage for our employees, our health insurance policy became self funded on April 1, 2006 as the Butler National Corporation Employee Health Care Plan.  The Plan has contracted with a managed care network of medical providers whose members have agreed to charge the Plan reduced or discounted charges for covered services provided to our employees and their families.  Although our employees have the freedom to choose to receive care from any physician, hospital or other medical care provider, as a general rule the amount or percentage of an otherwise covered expense payable by the Plan will vary, depending on whether the provider from whom the employee receives care is a member of the Plan's PPO network(s).  Generally, the Plan will pay a higher percentage of a covered expense if the care is received by a network provider.  The Plan Document, through a third party administrator controls all determinations related to coverage.  
As sales continue to grow we would anticipate overhead expenses to increase.  We continue to monitor and evaluate our overhead expenses in order to efficiently manage our operations.

|Liquidity and Capital Resources
At April 30, 2007, the Company had one line of credit totaling $1,000,000.  The unused line at April 30, 2007 was $250,216.  These funds are primarily used for the purchase of inventory for the modifications and avionics operations.
We believe the line of credit will be extended when it is due and do not anticipate the full repayment of this note in fiscal 2008.  Our line of credit has been extended to January 2008.  If the Bank were to demand repayment of all notes payable, we currently do not have enough cash to pay off the notes without materially adversely affecting the financial condition of the Company.  These notes are collateralized by the first and second positions on all assets of the Company.
At April 30, 2007 there were several notes collateralized by aircraft security agreements totaling $2,708,988.  These notes were used for the purchase and modifications of these collateralized aircraft.
There are two notes at the same bank totaling $1,094,583 for real estate located in Olathe, Kansas and Tempe, Arizona.  The due dates on these notes are August 2007 and November 2009.
Four notes to the same bank were entered into between March and April 2006 for the purchase of a building and several vacant lots in Junction City, Kansas.  One note has been paid in full and the remaining notes total $1,477,858.  Construction began on single-family residences in the summer of 2006.  Two notes totaling $1,627,603 are collateralized by the first and second position on all assets of the company.  The two notes are used as capital for our daily business operations.  There are several other notes collateralized by automobiles and equipment totaling an additional $62,689.

|We are not in default of any of our notes as of July 2, 2007.
We believe that our current banks will provide the necessary capital for our business operations.  However, we continue to maintain contact with other banks that have an interest in funding our working capital needs to continue our growth in operations in 2008 and beyond.
We do not, as of April 30, 2007, have any material commitments for other capital expenditures other than the terms of the Indian Management Agreements should any additional casinos materialize.  We will need additional funds to complete our planned Indian gaming opportunities.  We will use current cash available as well as additional funds, for the start up and construction of gaming facilities.  We anticipate initially obtaining these funds from internally generated working capital and borrowings.  
During fiscal 2008, we expect to apply for one or more Lottery Gaming Facility management agreements and appropriate licenses in the State of Kansas.  Funds to pay for feasibility studies, engineering, travel, architectural services, and other costs related to these applications will be generated from operations and short-term borrowings.  There is no assurance that these applications will be successful.
After a few gaming facilities become operational, gaming operations will generate additional working capital for the start up and construction of other gaming facilities.  We expect that our start up and construction financing of gaming facilities will be replaced by other financial lenders, long term financing through debt issues, or equity issues.Analysis and Discussion of Cash FlowDuring fiscal year 2007 our cash position increased by $863,592 and can be attributed to the following.   Cash provided by operating activities improved by $342,780.  During fiscal year 2007 we reported net income of $605,545.  Adjustment to net income provided by operations consisted of non-cash deduction for depreciation of $158,084, amortization for STC's of $232,504 and additional obsolescence of $21,166.  Issued as a match to the employee contribution to their 401(k) benefit plan resulted in an additional $212,977.  Cash used for operating activities resulted in a reduction of accounts receivable of $282,418.  Cash used for inventories was $941,398 of which we used funds for real-estate projects under construction of $1,261,329, and modification to aircraft of $199,287.  Defense products inventory decreased by approximately $125,000 along with a decrease in the aircraft modification inventory of approximately $395,000.  We have reduced our build up of inventory for the avionics and aircraft modification divisions but continue to have approximately six months of additional inventory for the defense product components and RVSM components.  Lead-time for the components is dictated by the market place resulting in the build up of inventory to support sales and avoid halting production because of material shortages.  We believe our inventory will be realized in the normal course of business.   Prepaid expenses and accounts payable used approximately $263,585.  Our customers increased deposits with us by approximately $538,000 during the last month of the fiscal year to support the build up of defense components inventory and we reduce our accrued liabilities by $61,885.

We invested $506,244 by adding the Learjet 30 series airplanes to our Learjet RVSM STC. Additional investment of $80,682 included building improvements, software and a new truck for our service division in Florida.

Cash provided by financing activities contributed $1,107,738 in cash.  We borrowed an additional $2,940,746 from our banks while reducing promissory notes of $1,013,982 and long term debt of $819,026.  This net contribution was used for real-estate projects under construction.Critical Accounting Policies and Estimates:
The Company believes that there are several accounting policies that are critical to understanding the Company's historical and future performance, as these policies affect the reported amount of revenue and other significant areas involving management's judgments and estimates. These significant accounting policies relate to revenue recognition, bad debts, the use of estimates, long-lived assets, Supplemental Type Certificates, advances to Indian gaming developments, and advances to state owned Lottery Gaming Facilities. These policies and the Company's procedures related to these policies are described in detail below and under specific areas within this "Management Discussion and Analysis of Financial Condition and Results of Operations." In addition, Note 1 to the consolidated financial statements expands upon discussion of the Company's accounting policies. Revenue Recognition:  We perform aircraft modifications under fixed-price contracts.  Revenues from fixed-price contracts are recognized on the percentage-of-completion method, measured by the direct labor costs incurred compared to total estimated direct labor costs.  Revenue for off-the-shelf items and aircraft sales is recognized on the date of sale.
Revenue from Avionics are recognized when shipped and payment for materials are due within 30 days of invoicing.  Revenue for SCADA services, Gaming Management, and other Corporate/Professional Services are recognized on a monthly basis as services are rendered.  Payments for these services are received within 30 days of invoicing.  
In regard to warranties and returns, our products are special order and are not suitable for return.  Our products are unique upon installation and tested prior to their release and have been accepted by the customers.  In the rare event of a warranty claim, the claim is processed through the normal course of business; this may include additional charges to the customer.  In our opinion any future warranty work would not be material to the financial statements.Bad Debts:  Bad debts are calculated on the historical write-off of bad debts of the individual subsidiaries.  Invoices are generally considered a bad debt if no payment has been made in the past 90 days.  We review these policies on a quarterly basis, and based on these reviews, we believe we maintain adequate reserves.  We do not anticipate substantial changes to these estimates in the future.  Use of Estimates:  The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.Long-lived assets:  Long-lived assets and identifiable intangibles to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.  Impairment is measured by comparing the carrying value of the long-lived asset to the estimated undiscounted future cash flows expected to result from use of the assets and their eventual disposition.  We determined that as of April 30, 2007, there had been no impairment in the carrying value of long-lived assets.Supplemental Type Certificates: Supplemental Type Certificates (STCs) are authorizations granted by the Federal Aviation Administration (FAA) for specific modification of a certain aircraft.  The STC authorizes us to perform modifications, installations, and assemblies on applicable customer-owned aircraft.  Costs incurred to obtain STCs are capitalized and subsequently amortized against revenues being generated from aircraft modifications associated with the STC.  The costs are expensed as services are rendered on each aircraft through costs of sales using the units of production method.  The legal life of an STC is indefinite.  We believe we have enough future sales to fully amortize our STC development costs.Advances for Indian Gaming Developments:  We are advancing funds for the establishment of Indian gaming.  These funds have been capitalized in accordance with Statements of Financial Accounting Standards (SFAS) 67 "Accounting for Costs and Initial Rental Operations of Real Estate Projects."  Such standard requires costs associated with the acquisition, development, and construction of real estate and real estate-related projects to be capitalized as part of that project.
Our advances represent costs to be reimbursed upon approval of Indian gaming in several locations.  We have agreements in place which require payments to be made to us for the respective projects upon opening of Indian gaming facilities.  Once gaming facilities have gained proper approvals, we plan to enter into a note receivable arrangement with the Tribe to secure reimbursement of advanced funds for that particular project.  
We have advanced and invested a total of $4,718,991 in Indian gaming developments.  We have reserves of $2,912,440, at April 30, 2007 and at April 30, 2006.  We believe that our advances for Indian gaming developments will be totally reimbursed as casinos are opened.  We believe it is necessary to establish reserves against the advances due to the fact that all of the proposed casinos are involved in legal and governmental actions whose outcome is not certain nor is there any time frame for resolution.  The reserve amount is an estimate of the value we would receive if a Tribal casino was not opened and we were forced to liquidate the assets that we have acquired with our advances.  These assets were intended to be used with Tribal casinos and consist of the purchase of land and land improvements related to the development of Indian Gaming facilities.  We believe that these tracts could be developed and sold for residential and commercial use to recover our advances if the gaming enterprises do not open.
In the years ended April 30, 2005 we increased reserves by $200,000 and did not change the reserves in 2006 or 2007.  We determine annually the amount of any increase in reserves based on our determination of the fair value of assets acquired by our advances for Indian developments.Changing Prices and InflationWe did experience some pressure from inflation in 2007.  From fiscal year 2006 to fiscal year 2007 we have experienced an increase in airplane travel, fuel, material, and transportation costs.  This additional cost may not be transferable to our customers resulting in lower income.  We anticipate long-term fuel costs and interest rates to continue to rise in fiscal 2008 and 2009.Off-Balance Sheet Arrangements
We do not have any off-balance sheet arrangements.

|We maintain a set of disclosure controls and procedures designed to ensure that information required to be disclosed in our filings under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission rules and forms.  Our principal executive and financial officers have evaluated our disclosure controls and procedures as of the end of the period covered by this Report on Form 10-K and have determined that such disclosure controls and procedures are effective.Evaluation of disclosure controls and procedures:  The Company's Chief Executive Officer (CEO) and Chief Financial Officer (CFO) have evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in the Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by the Annual Report (the "Evaluation Date").  In our opinion, as of the Evaluation Date, these disclosure controls and procedures were effective to ensure that material information relating to the Company and its consolidated subsidiaries would be made known to them by others within those entities and would be disclosed on a timely basis. The CEO and CFO have concluded that the Company's disclosure controls and procedures are designed, and are effective, to give reasonable assurance that the information required to be disclosed by the Company in reports that it files under the Exchange Act is recorded, processed, summarized, and reported within the time period specified in the rules and forms of the SEC. They have also concluded that the Company's disclosure controls and procedures are effective to ensure that information required to be disclosed in the reports that are filed or submitted under the Exchange Act are accumulated and communicated to the Company's management, including the CEO and CFO, to allow timely decisions regarding required disclosure. 

Changes to company internal controls:  In our opinion there were no material changes in the Company's internal controls over financial reporting during the three months ended April 30, 2007 that have materially affected, or are reasonably likely to materially affect, its internal controls over financial reporting.

|Item 11.  EXECUTIVE COMPENSATION
COMPENSATION DISCUSSION AND ANALYSIS: 

Our compensation programs are designed to support our business goals and promote both short-term and long-term growth. This section of the proxy statement explains how our compensation programs are designed and operate in practice with respect to our listed officers. Our listed officers are the CEO, CFO, and three most highly compensated executive officers in a particular year. The "Executive Compensation" section presents compensation earned by the listed officers for fiscal years ending April 30, 2007, 2006 and 2005.

The Compensation Committee of the Board of Directors determines the compensation for Butler National's executive officers. Our executive officers have the broadest job responsibilities and policy-making authority in the company. The Committee reviews and determines all components of executive officers' compensation, including making individual compensation decisions and reviewing and revising the executive officer compensation plans, programs, and guidelines as appropriate. The Committee also consults with management regarding non-executive employee compensation programs.

Our Compensation Philosophy

The core element of our overall compensation philosophy is the alignment of pay and performance. Total compensation varies with individual performance and Butler National's performance in achieving financial and non-financial objectives.  Our equity plans are designed to ensure that executive compensation is aligned with the long-term interests of our stockholders. The Committee and our management believe that compensation should help to recruit, retain, and motivate the employees that the company will depend on for current and future success. The Committee and our management also believe that the proportion of "at risk" compensation (variable cash compensation and equity) should rise as an employee's level of responsibility increases. This philosophy is reflected in the following key design priorities that govern compensation decisions:


pay for performance
employee recruitment, retention, and motivation
cost management
egalitarian treatment of employees
alignment with stockholders' interests
continued focus on corporate governanceEach element of compensation reflects one or more of these design priorities.  In most cases, our employees, including executive officers, are employed at will, without employment agreements, severance payment arrangements (except as required by local law), or payment arrangements that would be triggered by a "change in control" of Butler National.  Retirement plan programs are broad-based; Butler National does not provide special retirement plans or benefits solely for executive officers.

Total compensation for the majority of our employees including executive officers, includes two or more of the following components:


base salary
annual and semiannual incentive cash payments
equity grants (no grants since fiscal 2003)
Employee stock purchase plan
retirement benefits
health and welfare benefitsThe Compensation Committee and management continue to believe that a similar method of compensating all employees with cash, equity and retirement benefits supports a culture of fairness, collaboration, and egalitarianism.Determining Executive Compensation
The Committee reviews and determines the compensation for Butler's executive officers.  The Committee's process for determining compensation includes a review of Butler's executive compensation and practices, and an analysis, for each Butler executive officer, of all elements of compensation.  The Committee compares these compensation components separately and in total to compensation in the industry and each geographic location.  In determining base salary the Committee reviews company and individual performance information.Base Salary
The Committee establishes executive officers' base salaries at levels that it believes are reasonable for comparable positions.  When the Committee determines the executive officers' base salaries during the first quarter of the year, the Committee takes into account each officer's role and level of responsibility at the company.  In general, executive officers with the highest level and amount of responsibility have received the highest base salaries.  In January 2007, the Committee increased base salaries for the listed officers based on the Committee's review of the officers' current performance and expected future contributions.

I have reviewed this annual report on Form 10-K of Butler National Corporation;

Based on my knowledge, the financial statements, and other financial information included in this annual report, fairly represent in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this annual report;

|BUTLER NATIONAL CORPORATION AND SUBSIDIARIES
FINANCIAL STATEMENTS
AS OF APRIL 30, 2007
Report of Independent Registered Public Accounting FirmStockholders and Directors
Butler National Corporation
Olathe, Kansas

We have audited the accompanying consolidated balance sheets of Butler National Corporation as of April 30, 2007 and 2006 and the related consolidated statements of operations, shareholders' deficit, and cash flows for each of the three years in the period ended April 30, 2007, and the financial statement schedule listed in the Index at Item 15.  These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatements. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Butler National Corporation as of April 30, 2007 and 2006 and the consolidated results of its operations and cash flows for each of the three years in the period ended April 30, 2007 in conformity with U.S. generally accepted accounting principles.  Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole.  The Schedule of Valuation and Qualifying Accounts and Reserves (Schedule II) on page 60 is presented for purposes of additional analysis and is not a required part of the basic financial statements.  Such information has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

|BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES:
The accompanying consolidated financial statements include the accounts of Butler National Corporation (BNC) and its wholly-owned active subsidiaries, Avcon Industries, Inc., AVT Corporation, BCS Design, Inc., Butler National Services, Inc., Butler National Service Corporation, Butler National Corporation-Tempe, Butler National, Inc., Butler Temporary Services, Inc., and Kansas International Corporation (collectively, The Company).  All significant intercompany transactions have been eliminated in consolidation.
Avcon Industries, Inc. modifies business category aircraft at its Newton, Kansas facility.  Modifications can include passenger-to-freighter configuration, addition of aerial photography capability, and stability enhancing modifications.  Butler National Inc. acquires airplanes, principally Learjets, to refurbish and sell.  Butler National Corporation-Tempe is primarily engaged in the manufacture of airborne switching units used in Boeing McDonnell Douglas aircraft, electronic upgrades for classic weapon control systems used by the military, and transient suppression devices for Boeing 747 Classic aircraft.  Butler National Services is principally engaged in monitoring remote water and wastewater pumping stations through electronic surveillance.  Butler National Service Corporation is a management consulting and administrative services firm providing business planning and financial coordination to Indian tribes interested in owning and operating casinos under the terms of the Indian Gaming Regulatory Act of 1988.  BCS Design provides professional architectural services.Use of Estimates:  The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.
Inventories:  Inventories are priced at the lower of cost, determined on a first-in, first-out basis, or market. Inventories include material, labor and factory overhead required in the production of our products, and airplanes held for resale.
Inventory obsolescence is examined on a regular basis.  Inventory that has been inactive for a period of two years without use in normal and current productions are reserved as obsolete.  The obsolete inventory generally consists of Falcon and Learjet parts and electrical components.
Property and Related Depreciation:  Machinery and equipment are recorded at cost and depreciated over their estimated useful lives.  Depreciation is provided on a straight-line basis.  The lives used for the significant items within each property classification range from 3 to 39 years.
Maintenance and repairs are charged to expense as incurred.  The cost and accumulated depreciation of assets retired are removed from the accounts and any resulting gains or losses are reflected as income or expense.
Long-lived Assets:  Long-lived assets and identifiable intangibles to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.  Impairment is measured by comparing the carrying value of the long-lived asset to the estimated undiscounted future cash flows expected to result from use of the assets and their eventual disposition.  We determined that as of April 30, 2007, there had been no impairment in the carrying value of long-lived assets.
Advances for Indian Gaming Developments:  We are advancing funds for the establishment of Indian gaming. These funds have been capitalized in accordance with Statements of Financial Accounting Standards (SFAS) 67 "Accounting for Costs and Initial Rental Operations of Real Estate Projects."  Such standard requires costs associated with the acquisition, development, and construction of real estate and real estate-related projects to be capitalized as part of that project.
Our advances to the tribes for gaming developments are capitalized.  These advances represent costs to be reimbursed upon approval of Indian gaming in several locations.  We have agreements in place which require payments of advances to be made to us upon opening of Indian gaming facilities.  Once gaming facilities have gained proper approvals, we plan to enter into a note receivable arrangement with the Tribe to secure reimbursement of advanced funds for that particular project.  Reserves have been recorded for advances for the Indian gaming development costs when we are unable to determine whether reimbursement from the Tribes will occur.
We have advanced and invested a total of $4,718,991 in Indian gaming developments.  We have reserves of $2,912,440, at April 30, 2007 and April 30, 2006.  **Based on the information available to us we believe that our advances for Indian gaming developments will be totally reimbursed as casinos are opened.  Due to the fact that all of the proposed casinos are involved in legal and governmental actions whose outcome is not certain nor is there any time frame for resolution we believe it is necessary to establish reserves against the advances.  The reserve amount is an estimate of the value we would receive if a Tribal casino was not opened and we were forced to liquidate the assets that we have acquired with our advances.  These assets were intended to be used with Tribal casinos and consist of**the purchase of land, land improvements, professional design fees, and other consulting and legal costs related to the development of Indian Gaming facilities.  The land purchases are located adjacent to residential developments.  We believe that these tracts could be developed and sold for residential and commercial use to recover advances if the gaming enterprises do not open.
In the year ended April 30, 2005, we increased the reserve by $200,000 and did not change the reserve in 2006 or 2007.  We determine annually the amount of any increase in reserves based on our determination of the fair value of assets acquired by our advances for Indian developments.
Supplemental Type Certificates:  Supplemental Type Certificates (STCs) are authorizations granted by the Federal Aviation Administration (FAA) for specific modification of a certain aircraft.  The STC authorizes us to perform modifications, installations, and assemblies on applicable customer-owned aircraft.  Costs incurred to obtain STCs are capitalized and subsequently amortized against revenues being generated from aircraft modifications associated with the STC.  The costs are expensed as services are rendered on each aircraft through costs of sales using the units of production method.  The legal life of STCs are indefinite.  Consultant costs, as shown below, include costs of engineering, legal and aircraft specialists.  STC capitalized costs are as follows:

|Bank Overdraft Payable:  Our cash management program results in checks outstanding in excess of bank balances in the general disbursement account.  When checks are presented to the bank for payment, cash deposits in amounts sufficient to fund the checks are made from funds provided under the terms of our promissory notes agreement.
Financial Instruments:  The carrying value of cash and cash equivalents, short-term investments, accounts receivable, accounts payable, accrued expenses, and accrued employee costs approximate fair value because of the short-term maturity of these instruments.  Fair values are based on quoted market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates reflecting varying degrees of perceived risk.  Based upon borrowing rates currently available, the carrying value of notes payable long-term debt and capital lease 
obligations approximate fair value.
Revenue Recognition:  We perform aircraft modifications under fixed-price contracts.  Revenues from fixed-price contracts are recognized on the percentage-of-completion method, measured by the direct labor costs incurred compared to total estimated direct labor costs.  Revenue for off the shelf items and aircraft sales is recognized on the date of sale.
Revenue from Avionics are recognized when shipped and payment for materials are due within 30 days of invoicing.  Revenue for SCADA services, Gaming Management, and other Corporate/Professional Services are recognized on a monthly basis as services are rendered.  Payments for these services are received within 30 days of invoicing.  
In regard to warranties and returns, our products are special order and are not suitable for return.  Our products are unique upon installation and tested prior to their release and have been accepted by the customers.  In the rare event of a warranty claim, the claim is processed through the normal course of business; this may include additional charges to the customer.

|Stock-based Compensation: We account for non-employee stock-based awards in which goods or services are the consideration received for the equity instruments issued in accordance with the provisions of SFAS No. 123(R).
We have nonqualified stock option plans which provide key employees and consultants an opportunity to acquire ownership in the Company.  Options are granted under these plans at exercise prices equal to fair market value at the date of the grant, generally exercisable immediately, and expire in 10 years.  We account for these plans under Statement of Financial Accounting Standards No. 123(R).  The Company did not grant options for the fiscal years ending 2007, 2006, and 2005; therefore, there are no expenses relating to option grants for those periods.  There are 5,768,300 approved option shares available to grant under these plans.  The approved plan expiration date is December 31, 2010.
Income Taxes: Amounts provided for income tax expense are based on income reported for financial statement purposes and do not necessarily represent amounts currently payable under tax laws.  Deferred taxes, which arise principally from temporary differences between the period in which certain income and expense items are recognized for financial reporting purposes and the period in which they affect taxable income, are included in the amounts provided for income taxes.  Under this method, the computation of deferred tax assets and liabilities give recognition to enacted tax rates in effect in the year the differences are expected to affect taxable income.  Valuation allowances are established when necessary to reduce deferred tax assets to amounts that we expect to realize.
Cash and Cash Equivalents: Cash and cash equivalents consist primarily of cash and investments in a money market fund.  We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents.  We maintain cash in bank deposit accounts that, at times, may exceed federally insured limits.
Concentration of Credit Risk:  We extend credit to customers based on an evaluation of their financial condition and collateral is not required.  We perform ongoing credit evaluations of our customers and maintain an allowance for doubtful accounts.
Research and Development: We charge to operations research and development costs.  The amount charged in the year ended April 30, 2007 and 2006 was approximately $1,945,839 and $1,558,408 respectively.
Warranties:  We warrant to our customer that our products and services are in good working order at the time of delivery.  We warrant that these products will continue to be serviceable for periods from 90 days to up to a maximum of 36 months. Our products are tested and accepted by the customer prior to their release.  For the years ended April 30, 2007, 2006, 2005 we had no beginning warranty reserve, no additions to warranty reserves, and no reductions to the warranty reserve. 
In each of the three years ended April 30, our warranty expense was immaterial.
Recent issued accounting Standards:  September 2006, the Securities and Exchange Commission staff ("SEC") issued SAB 108. SAB 108 was issued to provide consistency to how companies quantify financial statement misstatements SAB 108 establishes an approach that requires companies to quantify misstatements in financial statements based on effects of the misstatement on both the consolidated balance sheet and statement of operations and the related financial statement disclosures.  Additionally, companies must evaluate the cumulative effect of errors existing in prior years that previously had been considered immaterial. We adopted SAB 108 in connection with the preparation of our annual financial statements for the year ended April 30, 2007 and found no adjustments necessary.
In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements ("SFAS No. 157"). SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements, rather, its application will be made pursuant to other accounting pronouncements that require or permit fair value measurements. SFAS No.157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those years. The provisions of SFAS No. 157 are to be applied prospectively upon adoption, except for limited specified exceptions. We are evaluating the requirements of SFAS No. 157 and do not expect the adoption to have a material impact on our Consolidated Balance Sheet or Statement of Operations.
In June 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No.48, Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109 ("FIN 48"). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in a company's financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes. It prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006 and will be adopted by us on May 1, 2007. We have not been able to complete our evaluation of the impact of adopting FIN 48 and as a result, are not able to estimate the effect the adoption will have on our financial position and results of operations, including our ability to comply with current debt covenants.
Accounts receivable:  Accounts receivable are carried on a gross basis, with no discounting, less the allowance for doubtful accounts.  Management estimates the allowance for doubtful accounts based on existing economic conditions, the financial conditions of the customers, and the amount and the age of past due accounts.  Receivables are considered past due if full payment is not received by the contractual due date.  Past due accounts are generally written off against the allowance for doubtful accounts only after all collection attempts have been exhausted.
Real estate construction in progress:  We are building some residential housing on real estate that we own.  We account for each structure separately and recognize our revenues and expenses on the percentage of completion method of accounting.  We have some real estate that we have not begun construction and have allocated costs on a per lot basis.

|3.  INCOME TAXES:
Deferred taxes are determined based on the estimated future tax effects of differences between the financial statement and tax basis of assets and liabilities given the provision of the enacted tax laws.  We have net operating loss carryforwards and cumulative temporary differences, which would result in the recognition of net deferred tax assets.  A valuation allowance has been provided which reduces the net deferred tax asset to zero.  At April 30, 2007, there is approximately $600,000 of net operating losses, which expire in 2008 to 2019.

|We are involved in various lawsuits incidental to our business.  Management believes the ultimate liability, if any, will not have an adverse effect on the Company's financial position or results of operations.

|We have a defined contribution plan authorized under Section 401(k) of the Internal Revenue Code.  All benefits-eligible employees with at least thirty days of service are eligible to participate in the plan; however there are only two entry dates per calendar year.  Employees may contribute up to twelve percent of their pre-tax covered compensation through salary deductions.  Each year we have chosen to match 100 percent of every pre-tax dollar an employee contributes.  Employees are 100 percent vested in the employer's contributions after three years of participation in the plan.  Our matching share contribution, at the then current market value, in 2007, 2006, and 2005 was approximately $212,977, $141,345, and $155,490 respectively.  If approved by the Board of Directors, the Company match is paid in common stock of the Company.

SELF FUNDED INSURANCEIn an effort to control our insurance costs and maintain quality health care coverage for our employees our health insurance policy became self funded on April 1, 2006, as the Butler National Corporation Employee Health Care Plan.  The Plan has contracted with a managed care network of medical providers whose members have agreed to charge the Plan reduced or discounted charges for covered services provided to our employees and their families.  Although our employees have the freedom to choose to receive care from any physician, hospital or other medical care provider, as a general rule the amount or percentage of an otherwise covered expense payable by the Plan will vary, depending on whether the provider from whom the employee receives care is a member of the Plan's PPO network(s).  Generally, the Plan will pay a higher percentage of a covered expense if the care is received by a network provider.  The Plan document, through a third party administrator controls all determinations related to coverage.  
To be eligible for coverage under this Plan you must be both an employee and an eligible employee.  An eligible employee must be regularly scheduled to work at least 30 hours per week, must have completed at least three months of employment and pay the employee's contribution share of the cost.  Coverage is effective at 12:01 a.m. on the first day of the month coincident with or first following the date of eligibility.
