a. U.S./EU Aviation Safety Agreement.

(1) The Agreement was signed on June 30, 2008. The Agreement’s official title is “Agreement Between the United States of America and the European Community on Cooperation in the Regulation of Civil Aviation Safety.”

(2) The Agreement allows the FAA and EASA to rely on each other’s surveillance systems, minimize the duplication of efforts, increase efficiency, and conserve resources to the greatest extent possible. As stated in Article 5 of the Agreement, areas of reciprocal acceptance, and technical differences, are specified in the Annexes; Annex 1 pertains to airworthiness and environmental certification, while Annex 2 pertains to maintenance.

(3) Annex 2 of the Agreement contains a mandate in paragraph 3.2 for the Joint Maintenance Coordination Board (JMCB) to develop, approve, and revise detailed guidance for processes covered by the Annex.

AC 145-11A 11/28/12

• FAA Order 8130.2, Airworthiness Certification of Aircraft and Related Products.

• FAA Order 8130.21, Procedures for Completion and Use of the Authorized Release Certificate, FAA Form 8130-3, Airworthiness Approval Tag.

• FAA Order 8900.1, Flight Standards Information Management System (FSIMS).

• Agreement Between the United States of America and the European Community on Cooperation in the Regulation of Civil Aviation Safety (the Agreement).

• Maintenance Annex Guidance Between the Federal Aviation Administration for the United States of America and the European Aviation Safety Agency for the European Union (the MAG).

7. BACKGROUND.

Page 2 Par 6

(4) The detailed guidance described in Annex 2 is contained in “Maintenance Annex Guidance Between the Federal Aviation Administration for the United States of America and the European Aviation Safety Agency for the European Union,” which is commonly referred to as the MAG.

b. Contents of the MAG. The MAG contains three sections (A, B, and C) that address the processes and procedures agreed to between EASA and the FAA. The sections are as follows:

(1) Section A—Authority Interaction (Not Applicable to Industry). This section applies to the FAA, EASA, and aviation authorities (AA). It provides the coordination and communication process for the regulatory agencies. It also includes FAA sampling and independent inspections and blank forms for the coordination process.

(2) Section B—Certification Process for U.S.-Based Repair Stations. This section identifies the requirements and processes for repair stations located in the United States to follow for obtaining an EASA approval.

(3) Section C—Certification Process for EU-Based Maintenance Organisations. This section identifies the requirements and processes for an EU-based AMO to follow for obtaining FAA certification and renewal. Additionally, it contains the responsibilities of both the FAA aviation safety inspector (ASI) and the AA.

a. General Information. Persons in the United States and EU maintaining both U.S. and EU aeronautical products should be familiar with the Agreement and the MAG.

b. Special Conditions. Particular attention should be focused on the differences between 14 CFR part 145 and EASA Part-145 which are identified as “special conditions” in Annex 2, Appendix 1, of the Agreement. An FAA-certificated repair station (CRS) located in the United States, when in compliance with EASA-published maintenance special conditions, may apply for EASA approval. Likewise, an EU-based AMO, when in compliance with published FAA maintenance special conditions, may apply for FAA approval.

c. Unimpeded Access. For the purposes of surveillance and inspections, the FAA and EASA (and AAs) will help each other gain unimpeded access to repair stations/AMOs subject to their respective jurisdictions. It is incumbent upon you to provide unimpeded access to EASA and the FAA to all work areas having civil aviation application. If you provide maintenance for both civil and military products, you should ensure, where possible, that there is clear delineation between work areas with civil and military applications within the repair station/AMO.

d. Training Program Requirements. For U.S. repair stations that have an EASA Part-145 approval, the human factors training is an EASA special condition requirement.

(1) Training should center on the scope of work you perform. You should also ensure the training program is controlled and developed per the FAA Repair Station Manual (RSM)/EASA supplement.
