PART 2. BILATERAL AVIATION SAFETY AGREEMENT (BASA) 

CHAPTER 1. GENERAL INFORMATION 

100. Part 2 of this AC gives guidance on the implementation of maintenance procedures 

negotiated with the BASA. This applies to U.S. repair stations, U.S.-or FAA-certificated airmen, 

Canadian AMOs, and Canadian AMEs. 

101. The Federal Aviation Administration (FAA) recommends that persons maintaining U.S. or 

Canadian aeronautical products be familiar with the BASA and the associated MIP. In 

particular, U.S. air carriers should ensure that Canadian AMOs comply with the requirements of 

any special conditions listed in the MIP and procedures contained in the air carrier manual. 

CHAPTER 2. BASA 

200. The United States and Canada, to facilitate acceptance by each country of airworthiness 

approvals along with environmental testing and approval of civil aeronautical products, entered 

into the BASA. The BASA also includes the approvals and monitoring of maintenance facilities 

and alteration or modification facilities, maintenance personnel, and airmen of the other party. 

The BASA Executive Agreement may be found at 

http://www.faa.gov/aircraft/air_cert/international/bilateral_agreements/. 

201. Each contracting party designated its civil aviation authority as the executive agent to 

implement this agreement. For the United States of America, the executive agent is the FAA of 

the Department of Transportation (DOT). For the Government of Canada, the executive agent is 

the Transport Canada Civil Aviation (TCCA) of the Department of Transport. 

202. The FAA and the TCCA acknowledge that oversight of repair stations, FAA-certificated 

airmen, AMOs, and AMEs is necessary to ensure quality of work performed and adherence to 

the regulatory requirements of each party. To facilitate this, each party agrees to provide access

on an unconditional basis to repair stations, FAA-certificated airmen, AMOs, AMEs, and 

noncertificated maintenance facilities performing maintenance on a U.S. or Canadian 

aeronautical product. Notification of visits to maintenance facilities needs to be made to the 

regulatory oversight agency for the repair facility being inspected. With this notification each 

authority may conduct independent inspections. Also, each authority may review the other 

authority’s surveillance records and other pertinent information for compliance to the MIP. The 

inspection will be conducted to ascertain that the performance of maintenance, preventive 

maintenance, and alterations are performed in accordance with the special conditions set forth in 

the MIP. The inspection is limited to the performance of work on the U.S. or Canadian 

aeronautical product. The inspection will not include determining the validity of the repair 

station, FAA-certificated airman, AMO, or AME certification or rating approvals. 

a. Repair stations, certificated airmen, AMOs, and AMEs remain subject to the regulatory 

requirements and enforcement procedures described in subparagraphs 3.0.2b and 3.1.2b of the 

Par 100 Page 3 
AC 43-10B 10/3/06 

MIP. FAA personnel will use the guidance in FAA Order 2150.3, Compliance and Enforcement 

Program, to process any enforcement actions against an AMO or AME. 

b. The FAA and TCCA will conduct periodic joint evaluations of each other’s continued 

compliance with the terms of the MIP. Such evaluations may include visits to repair 

stations/certificated airmen/AMOs/AMEs to ensure the accurate application of the MIP. 

CHAPTER 3. MAINTENANCE IMPLEMENTATION PROCEDURES 

300. This chapter describes the FAA and the TCCA procedures for implementing the 

maintenance and alteration or modification provisions of the Agreement for the Promotion of 

Aviation Safety (BASA) between the Government of the United States and the Government of 

Canada, signed 12 June 2000. The objective of the MIP is to outline the terms and conditions 

under which the FAA and the TCCA can accept each other’s inspections and evaluations of U.S. 

repair stations and Canadian AMOs along with FAA-certificated airmen and Canadian AMEs. 

301. The authorization for the MIP is Article III of the BASA. The FAA and the TCCA have 

assessed each other’s standards and systems relating to the approval of repair 

stations/AMOs/AMEs and FAA-certificated airmen that perform maintenance and alterations or 

modifications on civil aeronautical products, and as a result, have established an understanding 

of such standards and systems. 

302. The MIP may be amended by mutual consent of the FAA and the TCCA. Significant 

revision by either authority to its organization, regulations, procedures, or standards may affect 

the basis on which the MIP is executed. Accordingly, each authority agrees to promptly advise 

the other of plans for such changes, and to give an opportunity for comment. Upon notice of 

such changes by one authority, the other authority may request consultation to review the need 

for amendment to the MIP. 

303. The legal standards for safety regulation by the TCCA are contained in Canadian Aviation 

Regulations (CAR) and are explained in ancillary documents and procedures. The legal 

standards for safety regulation by the FAA are contained in Title 14 of the Code of Federal 

Regulations (14 CFR) and are explained in ancillary documents and procedures. 

CHAPTER 4. U.S. REPAIR STATIONS 

400. A person who applies for a repair station certificate must meet the requirements of 14 CFR 

part 145. These requirements include the manner of application, facility requirements, personnel 

requirements, quality control, and training requirements. Along with the certification 

requirements of part 145, applicants should use AC 145-9, Guide for Developing and Evaluating 

Repair Station and Quality Control Manuals, and AC 145-10, Repair Station Training Program. 

401. To be able to perform maintenance, preventive maintenance, and alterations on Canadian 

aeronautical products, repair stations must meet the applicable requirements contained in 

CAR 571 and 573. This may require revision to a repair station manual to incorporate a 

supplement to accommodate these requirements. The supplement may contain procedures 

unique to the Canadian aeronautical products, specific training requirements, and reporting 

Page 4 Par 202 
10/3/06 AC 43-10B 

requirements. This supplement may need approval by both the FAA and TCCA. The special 

condition in part 3, chapters 1 and 3 of the MIP, specify these unique requirements. 

CHAPTER 5. CANADIAN APPROVED MAINTENANCE ORGANIZATIONS 

500. APPLICANTS. 

a. An applicant for an AMO certificate or for an amendment of an AMO certificate makes an 

application in the form and manner specified in ch. 573 of the Airworthiness Manual. In addition, a 

person who holds an AMO certificate issued in accordance with CAR 573 cannot provide a service that 

is outside the scope of the person’s AMO certificate.

b. An applicant has to submit to the TCCA with an application, a copy of its maintenance policy 

manual (MPM) that is required by subsection 573.10(1). The TCCA then issues to a maintenance 

organization an AMO certificate authorizing the maintenance of specified aeronautical products or the 

provision of specified maintenance services. 

501. RATINGS. The AMO certificate will specify any category in which ratings have been 

issued and lists the aeronautical products that the AMO is authorized to maintain or the 

maintenance services that the AMO is authorized to perform. The scope of the work that may be 

performed under each rating specified on the AMO certificate is determined by limitations that 

are set out in the certificate. Unless an expiration date is specified in an AMO certificate, the 

certificate remains in effect until it is surrendered, suspended, or canceled. A capabilities list or 

other list will identify by make, model, or other nomenclature designated by the article 

manufacturer the articles on which the AMO is authorized to perform maintenance. The list is 

located in the AMO’s manual or as a referenced stand-alone document. The AMO must have the 

proper equipment, personnel, housing/facilities, materials, and technical data to maintain each 

article on the list. The list is an extension of the AMO’s certificate and its use depends on the 

AMO establishing procedures for conducting self-audits of its facility and capabilities, which are 

approved and accepted by the TCCA. 

502. FACILITIES. An AMO certificate holder must provide the facilities and equipment 

specified in chapter 573 of the Airworthiness Manual associated with the work to be performed. 

Except in cases provided for in an MPM, work will be performed in the AMO’s facilities. If

unforeseen circumstances do not permit the work to be performed in those facilities and the 

safety of the aircraft is not affected, the work may be performed elsewhere. An AMO will use 

the standards equivalent to those of the manufacturer of an aeronautical product for the 

performance of work. Those standards are identified in the CARs. 

503. CONTRACTING. An AMO must have the material and equipment necessary to perform 

the functions appropriate to its rating, but need not have the tools and equipment for functions it 

is authorized to contract out. An AMO may contract functions to TCCA certificated facilities 

and non-TCCA certificated sources as authorized and identified in its FAA Supplement to its 

manual. “Contracting” encompasses “subcontracting” as specified in TCCA requirements. 

TCCA will approve the list of functions to be contracted. Before contracting out a maintenance 

function, the AMO should: 

a. Establish procedures to qualify the contractor. 

Par 401 Page 5 
AC 43-10B 10/3/06 

b. Establish procedures to audit the contractor. 

c. List the contractor in its FAA Supplement. 

d. Provide technical training for receiving inspection personnel in contracted functions. 

e. Establish inspection procedures that provide enough technical detail so an airworthiness 

determination can be made based on a technical review of contractor-source documentation. 

504. CONTRACTING TO NON-TCCA CERTIFICATED SOURCES. 

a. If an AMO contracts work to a non-TCCA certificated source or another AMO, the AMO 

must be appropriately rated to perform the work. The AMO is responsible for the following: 

(1) Approving return to service items on which work has been performed. 

(2) Ensuring each item’s airworthiness. 

b. Any non-TCCA certificated source to which work is contracted must be under the control 

of the AMO’s quality monitoring system for the work performed. The AMO must inspect each 

item on which contracted work has been performed to ensure the airworthiness of the item. 

Receiving inspection procedures must enable the AMO to make an airworthiness determination 

of each item received. If the AMO cannot determine the quality of contracted work, the work 

can be contracted only to a TCCA certificated facility that is able to inspect the work performed 

for compliance with CAR 571. 

505. CONTRACTING TO TCCA CERTIFICATED FACILITIES. If an AMO contracts 

functions to another organization that is TCCA certificated, that organization is responsible for 

approval for return to service of each item on which work has been performed. The AMO 

should be able to determine that the TCCA certificated organization to which work is contracted 

is properly certificated to perform the work. Through the AMO’s receiving inspection 

procedures, the AMO must properly process items received from a TCCA certificated facility. 

506. AUDITS, TRAINING, AND RECORDS. The AMO should establish procedures to audit 

contractors and ensure that they comply with operators’ manuals, manufacturers’ manuals, and 

instructions for continued airworthiness (ICA). The AMO also must provide technical training 

for receiving inspection personnel who inspect contracted out functions. The organization also 

must establish a method of recording contracted work to ensure the records are retained for 

2 years. 

507. MAINTENANCE RELEASE. A maintenance release cannot be signed unless a person is 

authorized to sign in accordance with an MPM established by the holder of an AMO certificate 

issued under subsection 573.02. The AMO must have a rating for a category appropriate to the 

work performed. The person must have successfully completed a course of maintenance training 

that has been approved by the TCCA and that is applicable to the type of aircraft, engine, or 

system on which the maintenance is performed.

10/3/06 AC 43-10B 

CHAPTER 6. U.S.-CERTIFICATED AIRMEN

600. The requirements for a mechanic certificate and ratings, and the privileges, limitations, and 

general operating rules for certificated mechanics, are prescribed in 14 CFR part 65. When 

performing maintenance, preventive maintenance, or alterations on Canadian aeronautical 

products, the airman must comply with the appropriate sections of CAR 571. 

601. Maintenance performed on Canadian aeronautical products by FAA-certificated airmen 

must comply with the manufacturer’s recommendations or other TCCA-approved data. This 

applies to all maintenance, preventive maintenance, or alterations, with the exception of annual 

inspections. The airman who performed the work cannot approve major repairs or alterations for 

return to service. An airman with Inspection Authorization must make the return to service 

certification.

602. Part 65 prescribes recency of experience requirements for certificated airman. These 

requirements state that the airman must have performed or supervised the work within the last 

24 months. The airman may have supervised in an executive capacity the performance of work 

on an aircraft. In lieu of these requirements, the airman must be found able to perform the work 

by the FAA.

CHAPTER 7. CANADIAN AIRCRAFT MAINTENANCE ENGINEERS 

700. To gain an AME license, a person must submit an application in form and manner specified 

in chapter 566 of the TCCA’s Airworthiness Manual. This also applies to any endorsement of an 

AME license with a rating. The CARs state that an AME cannot exercise the privileges of an 

AME license unless the person holds an AME license, exercises the privileges in accordance 

with the ratings and any limitations endorsed on the license, exercises the privileges in 

accordance with Part V of the CARs. Any person who does not meet the conditions specified 

may sign a maintenance release if the person holds a restricted certification authority issued in 

accordance with Part V of the CARs. An AME license is valid for the period specified in the 

license. 

701. Recency of experience requirements in the CARs state that privileges cannot be exercised 

unless a person has had a license for the preceding 24 months. Also, the holder of the license 

must have, for at least 6 months within the preceding 24 months, performed or supervised 

aircraft maintenance, or supervised in an executive capacity the performance of aircraft 

maintenance. The AME may also have served as an aviation maintenance instructor or

supervised another aviation maintenance instructor in an aircraft maintenance-training course 

provided by an AMO. 

702. AMEs are authorized to return aircraft to service. The AME cannot permit anyone whom

the AME supervises to sign a maintenance release, unless the standards of airworthiness 

applicable to the maintenance performed and stated in chapter 571 of the Airworthiness Manual 

have been complied with and the maintenance release meets the applicable requirements 

specified in section 571.10 of the Airworthiness Manual. 

Par 600 Page 7 
AC 43-10B 10/3/06 

a. AMEs cannot sign a maintenance release for specialized maintenance unless the 

requirements of section 571.04 have been met. The exception to this is provided in its 

subsections 2 and 7; no person other than the holder of an aircraft maintenance engineer (AME) 

license issued under part IV, specifying a rating appropriate to the aeronautical product being 

maintained, can sign a maintenance release as required by section 571.10. 

b. If a maintenance release is signed by a person with respect of work performed by another 

person, the person signing the maintenance release must personally observe the work to the 

extent necessary to ensure that it is performed in accordance with the requirements of any 

applicable standards of airworthiness and, specifically, the requirements of sections 571.02 

and 571.10. 

703. RESTRICTED CERTIFICATION AUTHORITY. A person who is not the holder of an 

AME license specifying a rating appropriate to the aeronautical product being maintained may 

sign a maintenance release if the person holds a restricted certification authority. The TCCA 

must issue a restricted certification authority and specify therein its validity period and the scope 

of the work that may be performed, if: 

a. Application is made in accordance with section 571.11 of the Airworthiness Manual; 

b. The applicant demonstrates to the TCCA that there is no holder of an AME license

specifying a rating appropriate to the aeronautical product being maintained available within a 

geographical area accessible within 1 hour by surface transportation; 

c. The person to whom the restricted certification authority is to be issued has received the 

training and has the knowledge equivalent to that of a holder of an AME license specifying a 

rating appropriate to the aeronautical product being maintained; and 

d. The level of aviation safety is not affected by the issuance of the restricted certification 

authority.

10/3/06 AC 43-10B 

PART 3. SPECIAL CONDITIONS 

CHAPTER 1. GENERAL INFORMATION ABOUT PART 3 

100. Part 3 provides guidance on the special conditions that must be complied with when 

performing maintenance, preventive maintenance, and alterations on aeronautical products from

the United States or Canada. These special conditions apply to Canadian AMOs and AMEs as 

well as U.S. repair stations and certificated airmen. These special conditions can be found in 

appendix 4 of this AC. Only FAA or TCCA-approved or acceptable parts or components as 

applicable are used to perform maintenance, preventive maintenance, or alterations to U.S. or 

Canadian aeronautical products. 

101. Both Canadian AMOs and AMEs along with U.S. repair stations and certificated airmen 

must comply with the special conditions specified in the MIP. Certain conditions are applicable 

to both maintenance entities. 

CHAPTER 2. SPECIAL CONDITIONS FOR U.S AERONAUTICAL PRODUCTS 

200. FAA special conditions are applicable to Canadian-based AMOs and AMEs. These special 

conditions are required to be complied with to meet the requirements of 14 CFR part 43. These 

special conditions are in addition to any requirements of CAR 571 and 573. An AMO that 

applies to work on an aeronautical product under the regulatory control of the FAA may perform

maintenance, preventive maintenance, and alterations (with exception of annual inspections) on 

that product. In order to perform maintenance, the AMO must hold a valid AMO certificate 

issued by the TCCA in compliance with the most current CAR 571 and 573. 

201. AMOs that perform maintenance, preventive maintenance, and alterations for 14 CFR 

part 121 or 135 air carriers in commercial operations must have these additional items that 

include procedures to ensure compliance with part 121 or 135 air carriers’ manuals. The AMO 

will have a TCCA-approved FAA Supplement to its MPM that will specify how maintenance, 

preventive maintenance, and alterations are to be performed on U.S. aeronautical products. This 

supplement will include procedures to show separation of quality control functions from other 

maintenance functions, including the separation of maintenance from inspection on those items 

identified as required inspection items as defined by the part 121 or 135 air carrier/customer, if 

performing maintenance for air carriers in accordance with the requirements of part 121, 

subpart L or part 135, subpart J. 

202. To continue to hold an AMO authorization to maintain U.S.-certificated products, the FAA, 

or the TCCA on behalf of the FAA, may inspect it for continued compliance with CAR 571, 573 

and the special conditions. Investigations and enforcement by the FAA may be undertaken in 

accordance with FAA rules and directives and the AMO must cooperate with any investigation 

or enforcement action. 

203. To perform maintenance, preventive maintenance, and alterations on U.S. aeronautical 

products, Canadian AMEs must comply with the FAA special conditions. The AME must, 

Par 100 Page 9 
AC 43-10B 10/3/06 

among other requirements, ensure only FAA-approved parts or components are used. In 

addition, the AME must use the current manufacturer’s recommendations or ICA. Other special 

conditions are contained in the MIP located in appendix 4. 

CHAPTER 3. SPECIAL CONDITIONS FOR CANADIAN AERONAUTICAL 

PRODUCTS

300. An FAA-approved repair station or FAA-certificated airman may perform maintenance, 

preventive maintenance, and alterations (with exception of annual inspections) on a civil 

aeronautical product under the regulatory control of the TCCA. The TCCA acceptance will not 

exceed the scope of the ratings and limitations contained in the 14 CFR part 145 certificate, and 

authorized functions will be listed on the repair station capabilities list. Procedures must be 

included in the repair station manual that meets the requirements of the special conditions in the 

MIP (see appendix 4). FAA-certificated airmen must comply with the current CARs when 

performing maintenance on Canadian aeronautical products. 

301. A repair station that performs maintenance on Canadian air carriers operating in 

commercial air service under CAR IV or CAR VII must include in its manual a supplement that 

describes the procedures specified in the MIP, or explains where in the repair station manual 

those procedures are described, and is approved by the FAA. 

302. A repair station or FAA-certificated airman may continue to perform maintenance, 

preventive maintenance, and alterations on Canadian aeronautical products if inspection by the 

TCCA is allowed and the repair station cooperates with any investigation or enforcement action 

taken by the TCCA.

CHAPTER 1. GENERAL 

1.0. PURPOSE. 

a. This document sets forth the Federal Aviation Administration (FAA) and the Transport 

Canada, Civil Aviation Directorate (TCCA) procedures for implementing the maintenance and 

alteration or modification provisions of the Agreement for the Promotion of Aviation Safety 

between the Government of the United States (U.S.) and the Government of Canada signed 

June 12, 2000. The Agreement provides, in pertinent part, that the FAA and the TCCA will 

pursue mutual cooperation and technical assistance in evaluation and acceptance of each other’s 

systems, TCCA acceptance, and continued monitoring of maintenance and alteration or 

modification facilities. 

b. The objective of these Maintenance Implementation Procedures (MIP), in accordance 

with the Agreement, is to outline the terms and conditions under which the FAA and the TCCA 

can accept each other’s inspections and evaluations of United States repair stations and Canadian 

Aircraft Maintenance Organizations (AMO) along with FAA certificated airmen and Canadian 

Aviation Maintenance Engineers (AME) for findings of compliance, thereby reducing redundant 

regulatory oversight, without adversely affecting aviation safety. 

1.1. AUTHORIZATION. The authorization for this MIP is Article III of the Agreement for 

the Promotion of Aviation Safety, and in that respect, the FAA and the TCCA have assessed 

each other’s standards and systems relating to the approval of repair stations/AMOs/AMEs and 

FAA certificated airmen that perform maintenance and alterations or modifications on civil 

aeronautical products, and as a result, have established an understanding of such standards and 

systems. 

1.2. ENTRY INTO FORCE AND TERMINATION. This MIP shall enter into force 60 days 

after the date of the last signature and shall remain in force until terminated. The MIP may be 

terminated upon 60 days’ written notice by either the FAA or the TCCA. Termination of this 

MIP will not affect the validity of activity conducted under its provisions prior to termination. 

1.3. AMENDMENTS. 

a. This MIP may be amended by mutual consent of the FAA and the TCCA. Appendices 

also may supplement them. The details of any such amendment or appendix shall be recorded 

and signed by the representatives identified in paragraph 1.5b, or their designees. 

b. Suggestions for improvement are welcome and can be addressed to either of the offices 

described in paragraph 1.5. 

c. The FAA and the TCCA recognize that significant revision by either authority to its 

organization, regulations, procedures, or standards may affect the basis on which this MIP is 

executed. Accordingly, each authority agrees to promptly advise the other authority of plans for 

such changes, and to give an opportunity for comment. Upon notice of such changes by one 

authority, the other authority may request consultation to review the need for amendment to this 

MIP.

meetings will depend on the resources available to each authority, as well as the significance of 

any outstanding issues. 

4.1. INFORMATION. The FAA and the TCCA shall provide information and assistance 

regarding the maintenance and alterations or modifications to be performed under the terms of 

these implementation procedures, and shall develop appropriate publications and circulate these 

publications through their respective methods. The FAA and TCCA shall: 

a. Inform the public of the terms of the MIP and any amendments or appendices. 

b. Outline the regulatory requirements and special requirements necessary for persons to 

perform work under the terms of the MIP. 

4.2. TECHNICAL EVALUATION ASSISTANCE. The FAA and the TCCA agree to 

provide technical evaluation assistance to each other, upon request, to further the purposes and 

objectives of the MIP. Such areas of assistance may include, but are not limited to: 

a. Performing surveillance and providing reports regarding continued compliance with the 

requirements described in this MIP by AMOs and AMEs in Canada and repair stations in the 

United States. 

b. Conducting and reporting on investigations at the request of the other authority. 

c. Obtaining and providing data for reports when requested. 

4.3. EXCHANGE OF INFORMATION. The FAA and the TCCA shall provide each other 

with regulations, policies, guidance, practices, and interpretations relevant to the MIP, and shall 

ensure that such documents are updated in a timely manner. In addition, any FAA or TCCA 

proposal to amend such documents shall be provided to the other authority for the opportunity to 

review prior to the amendment being effected, consistent with its national laws and 

administrative procedures. 

4.4. ESTABLISHING AND AMENDING REGULATIONS, POLICIES, AND 

GUIDELINES. To the extent permitted by its national laws and administrative procedures, 

each authority agrees to provide technical assistance to the other in efforts to establish and 

amend regulations, policies, guidance, practices, and interpretations relevant to this MIP. 

4.5. URGENT OR UNUSUAL SITUATIONS. When urgent or unusual situations develop 

that are within the scope of the MIP, but not specifically addressed, the FAA and the TCCA will 

review and consult and take appropriate action, including developing amendments or appendices 

to the MIP, if appropriate, as set forth in Chapter 1, paragraph 1.3. 

4.6. NOTIFICATION OF NONCOMPLIANCE AND SAFETY ISSUES. 

a. The FAA and the TCCA agree to notify each other promptly of any investigation into 

noncompliance by a repair station or AMO under the regulatory control of the other authority 

that could result in revocation, suspension, or penalty. The notification shall be sent to the other 

authority’s representative identified in Chapter 1, paragraph 1.5a. The FAA and the TCCA agree 

that noncompliance will be corrected in a timely manner.

b. The FAA and the TCCA retain the right to take enforcement action but, in some cases, an 

authority may choose to consider a remedial action taken by the other authority. The 

enforcement consultation process under this MIP will be subject to a regular joint review by the 

FAA and the TCCA. 

4.7. PROTECTION OF PROPRIETARY DATA, FREEDOM OF INFORMATION ACT 

(FOIA), AND ACCESS TO INFORMATION ACT REQUESTS. 

a. Proprietary Data. Both authorities recognize that certain data submitted by a repair 

station/AMO/AME may be the property of that facility or another person and release of that data 

by the FAA or the TCCA is restricted. The FAA and the TCCA agree that they will not copy, 

release, or show proprietary data obtained from the other authority to anyone outside of the FAA 

or the TCCA without written consent of the owner of the proprietary data. 

b. FOIA Requests. The FAA often receives requests from the public under the FOIA to 

release information that the FAA may have in its possession. Any information that the FAA has 

in its possession must be disclosed under the FOIA unless it falls within certain exceptions, 

including trade secrets, or financial or commercial data that would be considered confidential or 

privileged. When the FAA receives such a request for the release of information related to an 

AMO in Canada and covered by the MIP, the FAA will advise the TCCA of any information 

received from the TCCA and submitted to the FAA that might be released. The FAA also may 

request the TCCA’s assistance, in cooperation with the AMO, in determining if the information 

submitter would object to release and which portions of the information received from the 

submitter or generated by the TCCA might be withheld under the FOIA exceptions, if any. 

c. Access to Information and Privacy Program (ATIP) Requests. The TCCA often 

receives requests from the public through the ATIP to release information in its possession. Any 

information that the TCCA has in its possession must be disclosed under the Access to 

Information Act unless it falls within certain exceptions, including information covered by the 

Privacy Act, trade secrets, or financial or commercial data that would be considered confidential 

or privileged. When the TCCA receives such a request for the release of information related to a 

repair station located in the United States and covered by the MIP, the TCCA will advise the 

FAA of any information received from the FAA and submitted to the TCCA that might be 

released. The TCCA also may request the FAA’s assistance, in cooperation with the repair 

station, in determining if the information submitter would object to release and which portions of 

the information received from the submitter or generated by the FAA might be withheld under 

the ATIP exceptions, if any. 

4.8. ACCIDENT/INCIDENT INVESTIGATION REQUESTS. When the FAA or the 

TCCA needs information regarding repair stations/AMOs/AMEs for the investigation of

accidents or incidents involving civil aeronautical products, the request for information should be 

directed to the office identified in Chapter 1, paragraph 1.5a. In turn, upon receipt of the request 

for information, the other authority will provide the requested information in a timely manner.

CHAPTER 5. INSPECTION AND CONTINUING VALIDITY PROVISIONS 

5.0. INSPECTION PROVISIONS. The FAA and the TCCA agree to the conduct of 

inspection, monitoring, and surveillance of repair station, FAA certificated 

mechanics/AMO/AME certificates currently under their regulatory control in accordance with 

this MIP. 

5.1. CONTINUING VALIDITY. The FAA and the TCCA acknowledge that: 

a. Unrestricted Access. With notice, each authority may conduct independent inspections 

of repair stations, FAA certificated mechanics, AMOs, and AMEs, and review the other 

authority’s surveillance records and other pertinent information. This applies to maintenance, 

preventive maintenance, or alterations performed on aeronautical products by repair stations, 

FAA-certificated mechanics, AMOs, and AMEs, consistent with the objective of this MIP and 

the authority’s applicable laws and regulations. 

b. Cooperation in Enforcement. The maximum permissible mutual cooperation and 

assistance in any investigation or enforcement proceedings of any alleged or suspected violations 

of any regulations or special conditions identified in the MIP is essential. The FAA and the 

TCCA acknowledge that repair stations, FAA- certificated mechanics, AMOs, and AMEs remain 

subject to the regulatory requirements and enforcement procedures described in Chapter 3, 

paragraphs 3.0.2b and 3.1.2b of this MIP. 

c. Continued Confidence Program. The FAA and TCCA shall conduct periodic joint 

evaluations of each other’s continued compliance with the terms of the MIP. Such evaluations 

may include repair stations/FAA-certificated mechanics/AMOs/AMEs to ensure the responsible 

authority is adequately applying the MIP.
