Appendix 1 SAMPLE—SPECIAL CONDITIONS (See Office Files for copies of Official MIP Document for each country.)

APPENDIX 1.

FEDERAL AVIATION ADMINISTRATION (FAA) SPECIAL CONDITIONS

CONTAINED IN MAINTENANCE IMPLEMENTATION PROCEDURES (MIP)

FAA Special Conditions are usually located in section 3.1 of the MIP. A sample of these Special Conditions are as follows:

3.1.1. The FAA agrees that a [specific National Aviation Authority (NAA) name will be inserted here]-approved maintenance organization that applies to work on a civil aeronautical product under the FAA’s regulatory control may be eligible for an FAA repair station certificate.

Eligibility is determined by whether the [NAA] endorses to the FAA that the maintenance organization complies with all of the following Special Conditions:

a. The maintenance organization must hold a valid Joint Aviation Regulation (JAR) 145 certificate issued by the [NAA] in compliance with the most current JAR 145 and all Acceptable Means of Compliance (AMCs), Interpretive Explanatory Materials (IEMs), and Joint Aviation Authority (JAA) Maintenance Temporary Guidance Leaflets (TGLs). The FAA will issue one FAA certificate for each maintenance facility location, appropriate to the functions and ratings at that location, even if multiple locations are covered by a single JAR 145 certificate.

b. The maintenance organization must provide an English language version of the management system. It also must provide a summary of its quality system for its JAR 145 maintenance organization exposition, as well as all applicable revisions to either prior to implementation.

c. The maintenance organization must provide an English language supplement that is accepted by the [NAA] on the FAA’s behalf and maintained at the maintenance organization.

All revisions must be accepted by the [NAA] and provided before implementation. This supplement to the maintenance organization manual shall include the following:

(1) Procedures for approval for release- or return to service that satisfy the requirements of 14 CFR Part 43 for aircraft and use of JAA Form 1 for components. This includes the information required by 14 CFR §§ 43.9 and 43.11 and all information required to be made or kept by the owner or operator, as appropriate.

(2) Procedures to ensure that major repairs and major alterations/modifications (as defined in 14 CFR) are accomplished in accordance with data approved by the FAA.

(3) Procedures to ensure that release- or return to service certification describes in the English language the maintenance, alterations, or modifications accomplished.

Appendix 1

(4) Procedures for reporting to the FAA serious defects or unairworthy conditions on civil aeronautical products.

(5) Procedures to ensure that all current and applicable airworthiness directives (AD) published by the FAA are available to maintenance personnel.

(6) Procedures to ensure compliance with air carriers’ manuals, including the separation of maintenance from inspection on those items identified by the air carrier/customer as required inspection items (RII).

(7) Procedures to ensure compliance with the manufacturer’s maintenance manuals or ICA and handling deviations.

(8) Procedures to ensure a hidden-damage inspection are accomplished, when applicable.

d. FAA certification under these MIP will not exceed the scope of the ratings and limitations in the JAR 145 certificate.

e. The maintenance organization employee responsible for supervision or final inspection of an aircraft of U.S. registry must be able to read, write, speak, and understand English.

f. The maintenance organization must state its FAA certificate number in any advertising in which it indicates it is FAA-approved.

g. The maintenance organization must display its FAA certificate in a location that is accessible to the public.

h. The maintenance organization must have, at the time of application, the materials and equipment necessary to perform the functions appropriate to the FAA certificate and ratings it seeks.

i. The maintenance organization must specify the items to be contracted and have procedures in place to ensure that contractors meet the terms of these MIP. For example, terms may include using an FAA-certificated source or, if using a non-FAA certificated source, the maintenance organization returning the product to service must be responsible for ensuring its airworthiness.

3.1.2. To continue to hold a 14 CFR Part 145 repair station certificate, a maintenance organization must meet the following conditions:

a. The maintenance organization must allow the FAA, or the JAA or the [NAA] on behalf of the FAA, to inspect it for continued compliance with JAR 145 and these Special Conditions (i.e., 14 CFR Part 145).

Appendix 1 Page 3 (and 4)

b. Investigations and enforcement by the FAA may be undertaken in accordance with FAA rules and directives.

c. The maintenance organization must cooperate with any investigation or enforcement action.

d. The maintenance organization must continue to comply with JAR 145 and these Special Conditions.

Appendix 2 The contents of each section of an FAA Supplement to the manual are explained in further detail below.

1. LIST OF EFFECTIVE PAGES (LEP). The FAA Supplement to the manual should begin with a list of the sections it contains, the page number of each section, and the current revision date of each section. This section may reference other appropriate sections of the AMO’s manual if that part is submitted with the Supplement and contains the page number and current revision date of the sections required by the Supplement. The NAA inspector should initial or sign the LEP when revised.

2. AMENDMENT PROCEDURES. The amendment procedures section should describe the procedures the organization will use to ensure that the FAA Supplement remains current. It should identify, by title, the person responsible for amending the FAA Supplement. It also should describe the procedures the organization will use to ensure that copies of any amendment to the Supplement are provided to and accepted by [name of NAA] before implementation. The procedures to ensure currency should be a part of the organization’s management system.

3. INTRODUCTION. The introduction section should do the following:

a. Indicate that the organization is performing work under the terms and conditions specified in the Bilateral Aviation Safety Agreement (BASA)/Maintenance Implement Procedures (MIP) executed between the FAA and [name of NAA]. This section also should indicate that the FAA Supplement, in conjunction with the approved NAA manual of the organization, defines the organization and procedures upon which compliance with applicable regulations are based.

b. State that the MIP permits the organization to obtain certification and renewal as a foreign repair station under 14 CFR Part 145 for performing work on aeronautical products subject to 14 CFR. Certification or renewal as a repair station is obtained after the FAA’s review and acceptance of the inspection, surveillance, and evaluation of the organization by [name of NAA].

c. Address the purpose of the FAA Supplement. This section also should indicate that it identifies the procedures that must be taken into account for the organization to perform work under the BASA/MIP and other appropriate regulations. These procedures are addressed by FAA Special Conditions in the MIP and may be in addition to those described in other portions of this manual.

d. State that the Supplement describes the methods and procedures the organization will use to ensure compliance with the FAA Special Conditions. These conditions are specified in the MIP executed according to a BASA.

4. ACCOUNTABLE MANAGER’S STATEMENT. The accountable manager’s statement section must contain the signed statement by the accountable manager. The accountable manager is the individual responsible for the organization’s compliance with 14 CFR. Such compliance is demonstrated by complying with the NAA regulations, requirements and associated material, and the FAA Special Conditions in the MIP.

Appendix 2

a. This statement agrees that the organization will comply with the conditions specified in the Supplement while operating under its FAA repair station certificate issued under the procedures specified in the MIP. The accountable manager’s statement is in lieu of the letter of compliance specified in FAA Order 8300.10, Airworthiness Inspector’s Handbook. That letter is signed by the person having overall responsibility for the repair station.

b. The accountable manager’s statement should contain the following or equivalent language:

“I understand that this organization, [name of company], when performing maintenance, alterations, or modifications on U.S.-registered aircraft or aeronautical products for use on such aircraft, must perform that work under the terms of the Maintenance Implementation Procedures (MIP) agreed to by the FAA and [name of NAA], and NAA regulations, requirements, and associated guidance material, as well as FAA Special Conditions set forth in the MIP and described in this organization’s FAA Supplement to its Manual.”

“As the person with overall control of [name of company], I have reviewed the NAA regulations and requirements and the FAA Special Conditions. This organization fully understands that by complying with these documents, it will be complying with the corresponding sections of 14 CFR Parts 43 and 145 and other applicable regulations. I understand that any deviations from these regulations and requirements may result in the loss of NAA approval or FAA certification, or in other certificate or enforcement action by the NAA or FAA. I also understand that loss of NAA approval automatically invalidates this organization’s 14 CFR Part 145 repair station certificate.”

“This organization will provide NAA and FAA personnel with access to our facilities to assess compliance with NAA requirements and FAA Special Conditions or to investigate specific problems.”

“I understand that this organization may be subject to FAA enforcement procedures. I understand that investigation and enforcement by the FAA regarding suspected violations of the FAR by this organization will be undertaken in accordance with FAA rules and directives, and that this organization must cooperate with any investigation or enforcement action.”

“I agree to ensure that this FAA Supplement will be maintained and kept current by this organization and be accessible to all personnel. I further agree to submit revisions to this Supplement to [name of NAA] for approval before implementing any such revisions.”

c. The statement must be signed and dated by the accountable manager.

Appendix 2

d. Whenever the organization’s accountable manager is replaced, the new accountable manager must sign and date an accountable manager’s statement. If required, the organization should forward a copy of the new signed statement to the NAA.

5. EXTENT OF APPROVAL.

a. General.

(1) The extent of approval section should do the following:

(a) State that the extent of FAA approval will not exceed the ratings and scope of work permitted under NAA regulations and requirements. The extent of FAA approval also will not exceed the scope of approval set forth in the organization’s Part 145 repair station certificate and OpSpecs.

(b) Note that although the NAA may issue an organization a single approval/certification for facilities that include line stations, the FAA will only recognize line stations that are listed in this section of the FAA Supplement to the manual and that are within the geographic borders of the MIP country. However, the FAA may, in certain limited circumstances, issue a single repair station certificate for multiple facility locations. These facilities must be within a reasonable proximity to each other and in the same country in which the BASA/MIP has been signed. Each location must meet the requirements of the MIP and be specifically identified in this section.

(c) Include the address of each location and the title of the person in charge at each location.

(2) FAA issuance of a specialized services rating requires FAA-approved process specifications. In this section, the organization should describe:

(a) The procedures it will use to ensure all work performed under the provisions of a specialized services rating is done in accordance with FAA-approved data.

(b) The procedures the organization will use to ensure that only FAA-approved processes are used on U.S.-registered aircraft or aeronautical products intended for installation on U.S.-registered aircraft.

(3) Scope. This section should identify the scope of approval authorized by the NAA and describe any limitations document the NAA has approved.

b. Capabilities List (CL). The manual’s CL should contain all the elements described in this AC’s paragraph 8b(7).

c. Work Away from the Repair Station.

Page 35 · 7Open in PDF

Appendix 2

(1) This subsection describes the procedures for conducting work away from the repair station to ensure compliance with the MIP. The subsection should also state that the repair station is authorized to perform work away from its facilities as specified in this subsection but the performance of such work must not exceed the scope of its FAA rating.

(2) A repair station may perform work at a place other than its fixed location when the occasion or the need arises, by moving facilities, material, equipment, and technical personnel to perform specific maintenance functions. This process cannot be used to establish a permanent location. Continuous operation at a permanent facility other than the repair station’s fixed location must not occur. Examples of routine maintenance functions done away from the repair station include the following:

/g183/g32 Testing altimeter systems

/g183/g32 Making nondestructive inspections (NDI)

/g183/g32 Responding to special circumstances such as an Aircraft On Ground (AOG) requiring repairs so it can be flown safely from an isolated airport to the operator’s main base or repair station

(3) This subsection also should describe how work will be accomplished in the same manner as work performed at the repair station’s fixed location. The repair station should acknowledge that these procedures apply only to work performed at other locations. This subsection should:

(a) Describe the procedures used to ensure that FAA technical data, such as manufacturers’ manuals, service bulletins, and letters, are current and accessible at the location where the work is performed.

(b) Describe the procedures used by the organization to control tools and ensure proper equipment calibration when away from the repair station’s fixed location.

(c) Describe how the organization will ensure that records for work performed away from the repair station will be maintained in the same manner as at the repair station’s fixed location.

(d) Describe how the organization will ensure that personnel performing work away from the repair station’s fixed location will be trained and qualified to perform the required work.

(e) List by title the persons who are authorized to approve an item for return to service when working away from the repair station’s fixed location.

(f) List by title the persons responsible for organizing and supervising work away from the repair station’s fixed location.

Page 36 · 8Open in PDF

Appendix 2

(g) Describe how the organization will ensure that all required personnel, equipment, materials, and parts will be made available at the place where the work is to be performed.

(h) State the organization’s responsibility to maintain a record of work performed away from the repair station, both within the country and outside the country. Any record of this work should include:

i. A description of the work performed;

ii. The date and location where the work was performed; and

iii. The work order number (total time in service if required).

(i) These records should be retained for 2 years after the performance of the work.

Prior FAA approval of this work is not required. This section also should state the organization’s responsibility to provide a copy of the records upon request to the FAA IFO/CHDO responsible for the oversight of the repair station.

d. Geographic Authorization. This subsection should contain procedures for an organization with a geographic authorization to carry out work under contract for an FAA-certificated U.S. air carrier or 14 CFR Part 129 operator of U.S.-registered aircraft. The subsection should list, at a minimum:

(1) The name of each air carrier for which work has been contracted;

(2) Each location where the work will be accomplished;

(3) The title of each person in charge at each location;

(4) How the organization will comply with NAA requirements and FAA Special Conditions; and

(5) How the organization will comply with the requirements in an air carrier’s manual.

The contents of this subsection may vary widely among repair stations, depending on the number of air carriers for which work is performed and the number and complexity of the geographic authorizations.

e. Line Stations. Although the NAA/JAA may issue a single NAA certificate for AMO facilities that include line stations, the FAA normally will issue a separate repair station certificate for each AMO. However, under the BASA/MIP agreement, the FAA will recognize the line stations within the boundaries of the MIP country listed in the AMO’s manual. This subsection should list the line stations located within the BASA/MIP country at which the AMO intends to use its FAA repair station certificate. The AMO may reference another section of the manual that identifies the line stations that will be working under the BASA/MIP. These line stations will be under the surveillance purview of the NAA. The FAA will accept the line
