Change:

1. PURPOSE. This advisory circular (AC) is intended to provide information and guidance 

concerning acceptable means, but not the only means, that should be used by repair station 

certificate holders in the United States to obtain Joint Aviation Authorities (JAA) and foreign 

National Aviation Authority (NAA) acceptance under the provisions of Maintenance 

Implementation Procedures (MIP) concluded pursuant to a Bilateral Aviation Safety Agreement 

(BASA). 

2. FOCUS. This AC applies to repair station certificate holders who must demonstrate 

compliance with requirements for JAA and NAA acceptance. This AC has been subjected to

comment from various NAAs and the JAA. However, persons should be aware that, ultimately, 

responsibility for administration of NAA requirements and the Joint Aviation Requirements 

(JAR) rests with the respective NAAs and the JAA. Accordingly, legal resolution of NAA and 

JAR compliance issues raised by this AC should be directed to the relevant NAA or the JAA. 

3. CANCELLATION. AC 145-8, Acceptance of Repair Stations by the JAA and JAAMember NAAs Under the Maintenance Implementation Procedures of a Bilateral Aviation Safety

Agreement, dated March 29, 1999, is cancelled.

5. BACKGROUND.

a. JAR 145 requirements, established by the JAA, are similar to 14 CFR part 145. JAR 145 

has been adopted by all JAA-member NAAs and includes requirements repair stations must 

comply with to qualify as a JAA-accepted maintenance organization. JAR 145 also includes a 

requirement specifying that the maintenance of all aircraft registered in JAA-member countries 

that are used in commercial air transport operations be performed by a maintenance organization 

approved or accepted by the JAA. 

b. A repair station certificated under 14 CFR part 145 and located in the United States may

qualify for acceptance by the JAA as a maintenance organization in accordance with JAR 145.10, 

Applicability. JAR 145.10 permits organizations located outside the territories of the countries 

that have joined the JAA to be accepted when working in accordance with JAA maintenance 

special conditions detailed in the MIP of a BASA. 

c. As a result of these provisions, a repair station certificated under 14 CFR part 145 may be 

accepted by the JAA on behalf of the JAA-member NAA providing the repair station complies 

with special conditions in addition to the requirements of 14 CFR part 145. These conditions are 

specified in the MIP executed between the FAA and various JAA-member NAAs. These special 

conditions are listed in Appendix 1 of this AC and further described in JAA Maintenance Leaflet 

No. 22. A repair station accepted by the JAA may perform work on any aircraft registered in a 

JAA-member country. A repair station accepted by the JAA has the acceptance of all JAAmember NAAs and does not require independent certification by a JAA-member NAA.

6. DEFINITIONS. 

a. Bilateral Aviation Safety Agreement (BASA). An executive agreement between the 

United States and a foreign country for the purpose of promoting aviation safety, also known as 

an Agreement for the Promotion of Aviation Safety. 

Page 2 Par 4 
4/3/03 AC 145-8A 

b. Compliance with JAR 145. Compliance with the latest issue of 14 CFR part 145 and the 

special conditions as set forth in an MIP, recognizing that ACs provide additional guidance in 

this area.

c. Joint Aviation Authorities (JAA). An organization consisting of representatives of the 

Civil Aviation Authorities (CAA) of the countries that have signed the Arrangements Concerning

the Development and the Acceptance of the Joint Airworthiness Requirements. JAA member 

countries consist primarily of European Union member countries. However, in recent years, the 

JAA has expanded into countries located outside the European Union. A listing of the member 

countries may be obtained by contacting the JAA at Joint Aviation Authorities, Saturnusstraat 

8-10, P.O. Box 3000, 2130 KA Hoofddorp, Netherlands; telephone: 31-23-56-79711; facsimile: 

31-23-56-21714. You may also subscribe to the JAA web page.

d. JAA/NAA Acceptance. JAA procedures by which the JAA accepts an FAA-certificated 

repair station seeking a JAA listing to perform work on civil aeronautical products under the 

regulatory control of any JAA-member NAA. Such JAA procedures involve issuing a JAA 

acceptance and entering information concerning the FAA-certificated repair stations accepted by

the JAA into a list published by the JAA of certificated repair stations. Continued listing is 

predicated on the continued monitoring and approval of such facilities by the FAA.

e. Joint Aviation Requirements (JAR). The JAR are a uniform set of regulations issued by

the JAA. The JAR are interpreted and implemented by JAA policy guidance in the form of

Interpretive Explanatory Material (IEM), Acceptable Means of Compliance (AMC), JAA 

Maintenance Leaflets, and JAA Administrative and Guidance Material, Section Two: 

Maintenance.

f. Maintenance Implementation Procedures (MIP). Procedures for implementing the

provisions of a BASA that apply to maintenance.

g. National Aviation Authority (NAA). The aviation regulatory authority of a foreign 

country.

h. Special Conditions. Conditions in a MIP that specify the requirements in 14 CFR 

part 145 that the FAA has determined are not contained in JAR 145 (FAA Special Conditions) 

and the requirements in JAR 145 that an NAA has determined are not contained in 14 CFR 

part 145 (JAA Special Conditions). NAA Special Conditions are based on the JAA Special 

Conditions in Appendix 1 of this AC.

7. DISCUSSION.

a. General. A repair station seeking JAA/NAA acceptance under JAR 145 must hold a 

valid repair station certificate and operations specifications (OpSpecs) issued under 14 CFR 

part 145, and must be located in the United States. Acceptance by the JAA is limited to the 

scope of work specified in the OpSpecs issued to the repair station. A repair station that has 

obtained JAA acceptance has the acceptance of all JAA-member NAAs and, subject to the terms 

Par 6 Page 3 
AC 145-8A 4/3/03 

of its OpSpecs, may perform work on any aeronautical product under the regulatory control of 

any JAA-member NAA. 

b. Procedures for Obtaining Initial JAA/NAA Acceptance Under JAR 145.

(1) A repair station seeking initial JAA/NAA acceptance under JAR 145 should request 

an application packet from the FAA FSDO with certificate oversight responsibility. This 

application packet will contain a copy of this AC and JAA Maintenance Leaflet No. 22. JAA 

Maintenance Leaflet No. 22 provides guidance on compliance with those provisions of JAR 145 

not addressed in 14 CFR part 145. It also contains a sample JAA Supplement to a repair 

station’s Inspection Procedures Manual (IPM) and JAA Form 16. 

(2) The repair station should prepare two copies of JAA Form 16 and two copies of its 

JAA Supplement to its IPM. The proposed JAA Supplement should conform to the sample JAA 

Supplement contained in JAA Maintenance Leaflet No. 22. 

(3) The repair station should provide evidence of its need for JAA acceptance. This 

evidence may be a letter of intent, contract, or work order from a JAR 145-approved maintenance 

organization, a 14 CFR part 145 repair station located in the United States that is JAA-accepted, 

a Transport Canada Civil Aviation AM573-certificated maintenance organization located in 

Canada that is JAA-accepted, or a European airline or air taxi organization. 

(4) The repair station should submit two copies of JAA Form 16 and the proposed JAA 

Supplement and one copy of evidence stating its need for JAA acceptance to its supervising

FSDO for review. 

(5) The assigned FAA inspector will conduct a physical inspection of the repair station 

for compliance with the JAA Supplement using JAA Form 9, FAA Status Report on a JAAAccepted FAR Part 145 Repair Station or Applicant for JAA Acceptance, subject to resource 

availability. FAA inspectors may obtain the current copy of JAA Form 9 at: 

http://afscentral.faa.gov/publications.htm. 

(6) The FAA will recommend acceptance of the repair station to the JAA when they are 

satisfied that the repair station is in compliance with 14 CFR parts 43 and 145 and the proposed 

JAA Supplement, subject to the satisfactory outcome of any inspection. If any deficiencies are 

noted in an inspection, they must be corrected within 60 days of the FAA’s notification to the 

repair station. If the deficiencies have not been corrected within 60 days, the FAA will terminate 

the application. In the event of unusual circumstances, the FAA may extend the 60-day period 

provided the applicant demonstrates an ability and willingness to correct the noted deficiencies. 

The FAA will not issue a positive recommendation until all deficiencies have been corrected. 

Therefore, the JAA will not issue an acceptance unless it has received a positive recommendation 

from the FAA. 

(7) An initial acceptance fee should be sent to the JAA account specified on 

JAA Form 16 at least 30 days before the date initial acceptance is needed. Electronic transfers 

Page 4 Par 7 
4/3/03 AC 145-8A 

should quote the information on page 2 of the latest version of JAA Form 16. The fee is 

nonrefundable. 

(8) After receiving a positive recommendation from the FAA and proof of initial fee 

payment, the JAA will forward a JAA acceptance to the repair station and a copy to the repair 

station’s principal inspector. A JAA acceptance is valid for up to two years. 

c. Procedures for Renewing JAA/NAA Acceptance Under JAR 145. 

(1) A repair station seeking renewal of its acceptance should request an application 

packet from the FAA FSDO with certificate oversight responsibility for the repair station. 

(2) The repair station should complete JAA Form 16 in duplicate.

(3) The repair station should obtain/provide evidence of its need for JAA acceptance as 

specified in paragraph 7b(3) of this AC. The evidence of need may consist of a copy of 

Form 8130-3, Airworthiness Approval Tag, indicating that the repair station has performed 

maintenance for an organization located in a JAA member country. 

(4) The repair station should check to ensure that its JAA Supplement reflects current 

repair station procedures and activities. If current procedures are reflected in the document and 

the document has been previously submitted to the FAA, the repair station’s JAA Supplement 

does not need to be revised or resubmitted. Any changes will require revision of the JAA 

Supplement and resubmission to the FAA. 

(5) The repair station should send two copies of JAA Form 16 as well as any amendment 

to its JAA Supplement, if appropriate, and a copy of its evidence of need for JAA acceptance to 

its supervising FSDO at least 60 days before the expiration of its current JAA acceptance. This 

will ensure continuity of the acceptance unless significant changes have taken place since the last 

issue or renewal of acceptance. 

(6) The repair station must have two FAA facility inspections performed during the

preceding two years. Outstanding issues resulting from these facilities inspections must be 

resolved. 

(7) When the repair station is in compliance with 14 CFR parts 43 and 145 and the JAA 

Supplement (including amendments), the FAA will recommend renewal of its JAA acceptance on 

JAA Form 9. When the repair station is not in compliance, the FAA may allow the repair station 

to submit a plan for corrective action, depending on the nature of the deficiencies. If the repair 

station fails to correct the deficiencies or provide a plan for corrective action, the FAA will 

terminate the renewal application and submit JAA Form 9 to the JAA with a non-recommendation 

of acceptance. In the event of unusual circumstances, the JAA may extend the duration of the 

repair station’s acceptance for a reasonable period of time. The JAA will not issue an acceptance 

unless it has received a positive recommendation from the FAA. 

Par 7 Page 5 
AC 145-8A 4/3/03 

(8) The repair station should send a renewal fee to the JAA account specified on 

JAA Form 16 at least 30 days before its current acceptance expires. Electronic transfers should 

quote the information contained on page 2 of JAA Form 16. The fee is nonrefundable. 

(9) After receiving a positive recommendation from the FAA and proof of fee payment, 

the JAA will forward a JAR 145 acceptance to the repair station and a copy of the acceptance to 

the repair station’s principal inspector. 

(10) Late application for renewal. The JAA must be in receipt of the FAA 

recommendation, the completed renewal application, and confirmation that the fee has been paid 

no later than 60 days from the scheduled renewal date. Any application package received by the 

JAA later than 60 days from the scheduled renewal date will be returned to the applicant and a

copy to the FAA with a denial of renewal. The applicant should proceed using the initial 

acceptance procedures. 

d. Procedures for Amending JAA/NAA Acceptance Under JAR 145. 

(1) A repair station seeking to amend its acceptance should follow the procedures for a 

repair station seeking initial acceptance as specified in this AC, except as noted in this section. 

(2) An amendment of acceptance requires the submission of JAA Form 16 for changes to

a repair station’s name, ownership, location, or ratings. Amendments issued to a repair station’s 

JAA acceptance will not change the expiration date of the repair station’s current acceptance. 

Depending on the nature of the proposed amendment, the FAA may need to perform a limited 

facility inspection of the repair station. 

(3) The repair station should revise its JAA Supplement to reflect any changes resulting

from amending its JAA acceptance and resubmit only the changes. Revisions to the repair 

station’s JAA Supplement that do not change the nature of the repair station’s JAA acceptance 

should be submitted to the FAA for review but do not require the submission of JAA Form 16. 

Evidence of the repair station’s need for JAA acceptance is not required to be submitted for an 

amendment of acceptance. 

(4) No fee is required for amending an existing JAA acceptance; therefore, the fee 

section of JAA Form 16 is not applicable. 

e. Additional Conditions for the Acceptance of Air Carrier Line Stations. 

(1) While this JAR 145 procedure is primarily intended for the acceptance of 14 CFR 

part 145-certificated repair stations located in the United States, it can also be extended to line 

stations of a U.S. air carrier that is a 14 CFR part 145 certificate holder. 

(2) Air carrier line stations in the United States can be accepted by the JAA if the air 

carrier holds a 14 CFR part 145 certificate valid for all operated aircraft types for at least one of 

its base maintenance facilities and shows that its quality monitoring system covers operations 

conducted under both certificates and at the line stations. 

Page 6 Par 7 
4/3/03 AC 145-8A 

(3) A U.S. air carrier seeking JAA acceptance for a line station outside the United States 

should contact its Principal Maintenance Inspector to obtain assistance in applying to the JAA for 

acceptance of the line station.
