Page 1 of 6Hawker Beechcraft Corporation expressly reserves the right to supersede, cancel and/or declare obsolete any parts, part numbers, kits or publications that may be referenced in this manual without prior notice. Warning: Use only parts obtained from sources approved by Hawker Beechcraft Corporation, in connection with the maintenance and repair of Hawker Beechcraft Corporation airplanes. Genuine Hawker Beechcraft Corporation parts are produced and inspected under rigorous procedures to insure airworthiness and suitability for use in Hawker Beechcraft Corporation airplane applications. Parts purchased from sources other than those approved by Hawker Beechcraft Corporation, even though outwardly identical in appearance, may not h ave the required tests and inspections performed, may be different in fabrication techniques and mate rials, and may be dangerous when installed in an airplane. Salvaged airplane parts, reworked parts obtained fr om sources not approved by the Hawker Beechcraft Corporation or parts, components or structural assem blies, the service history of which is unknown or cannot be authenticated, may have been subjected to unacceptable stresses or temperatures or have other hidden damage, not discernible through routine visual or usual nondestructive testing techniques. This may render the part, component or structural assembly, even though originally manufactured by the Hawker Beechcraft Corporation, unsuitable and unsafe for airplane use. Hawker Beechcraft Corporation expressly discla ims any responsibility for malfunctions, failures, damage or injury caused by use of parts not approved by the Hawker Beechcraft Corporation. Any maintenance requiring the disconnection and co nnection of flight control cables, plumbing, electrical connectors or wiring requires identification of each side of the component being disconnected to facilitate correct reassembly. At or prior to disassembly, components should be color coded, tagged or properly identified in a way that it will be obvious how to correctly reconnect the components. After reconnection of any component, re move all identification tags. Check all associated systems for correct function prior to returning the airplane to service.

## 3. INSPECTION PROCEDURES

Wherever this manual addresses a specific area or comp onent, it is implied that the in spection will include reasonable observation and evaluation of the surro unding area. Airplane components that may have been modified by STC are not the responsibility of Hawker Beechcraft Corporation and are no t covered by this manual. Insp ection of any such component affected by this manual must automatically be referred to the STC holder for FAA approval guidelines. Note: Any inspection findings, repairs and modifica tions accomplished must be communicated to Hawker Beechcraft Corporation within 10 days in order to access the effectiveness of the recommended inspection procedures and time intervals. Send all available data, including repairs, photos, sketches, etc., to Hawker Beechc raft Corporation at the address on the report form. An example of a re port form is provided in the REPORT FORM section of this chapter. Blank report forms for each check are provided after the FORMS tab section of this manual for copyin g and use. Contact Hawker Beechcraft Corporation Airline Technical Support at the following numb ers for repair information not available in other Hawker Beechcraft Corporation publications and fo r information concerning technical support documents applying to your airplane: Telephone: 316.676.7016 or Fax: 316.676.8051. 

## A. Inspection Schedule The Airworthiness Limitations Manual specifies the time limit s for accomplishing the various inspections included in this manual. Detailed procedures for each inspection are out lined in the appropriate sections of this manual.
The initial times and intervals for particular inspections are expressed in flig ht hours, while the fuselage inspections are expressed in both hours and cycles. The inspection times and intervals are considered to be nominal times. If the initial inspection is specified as 12, 000 hours and the sp ecified interval is 3,000 hours, the nominal inspection times will be at 12,000 hours, 15,000 hours, 18,000 hours, et c. In order to coordinate these ins pections with the Continuous Inspection Program outlined in Chapter 5 of the Model 1900/1900C Airlin er Maintenance Manual, any inspection specified in the inspection schedule may be varied by an amount of time not to exceed 10% of the inspection interval specified in the inspection schedule. However, under no circumstances can the interval between any two inspections be allowed to exceed 110% of the interval. For example, if a nominal in spection point is 15,000 hours and the specified inspection interval is 3,000 hours, that inspection may be performed as early as 14,700 hours or as late as 15,300 hours. The next inspection must be performed within 3,300 hours provided the 10% variance about the nominal inspection point is not exceeded. Therefore, if the last inspection was completed at 14,700 hours, the next inspection must be performed no later 7/16/2013 1:53:31 PM

Page 4 of 6than 18,000 hours. However, if the last inspection was comp leted at 15,300 hours, the nex t inspection must be performed no later than 18,300 hours. It is permissible to perform the initial fuselage or wing in spection early to accommodate fleet scheduling. However the subsequent recurring in spections will be set to re-occur at 3,000 hours from the initial time. Exam ple: Initial fuselage inspection at 10,500 hours, the next inspection will be due at 13, 500 hours. The Empennage inspection is expressed in calendar time for the initial inspection while th e repetitive inspections are expressed in airframe hours. 

## B. Inspection Intervals The structural inspection intervals for the 1900/1900C airliners are in the Model 1900 Airliner Series Airworthiness Limitations Manual, P/N 129-590000-133. 

## C. Report Form Example An example of a Check Discrepancy Report Form is shown below. Note: Complete the appropriate CHECK DISCREPANCY REPO RT form each time this inspection is performed. Discrepancies revealed during this inspection must be repaired. Applicable repair procedures may be found in the Model 1900 Airliner Series Structural Repair Manual . Report each discrepancy found and the corrective action taken to clear the discrepancy. If no discrepancies were found, write the word NONE on the form. Please mail the completed form to the address indicated at the bottom of the form. If required, mark any discrepant areas on a photo and attach it to the report form. A blank copy of the various report forms is provided in each section of this manual and after the FORMS tab section of this manual. Copy the appropriate form as required for the inspection being performed.
