Bilateral Agreements Between Countries and Agencies

Aviation authorities worldwide have bilateral agreements and mutual recognition treaties to streamline aircraft maintenance and repair station approvals across borders. Here’s how major regulators acknowledge or cooperate with each other:

FAA (USA) and EASA (Europe)

• Agreement: FAA-EASA Bilateral Aviation Safety Agreement (BASA)
• Recognition: EASA accepts FAA Part 145 repair stations, and vice versa, but with some additional conditions.
• Example: A U.S.-based FAA-certified repair station can apply for an EASA Part 145 approval with an EASA Supplement.

FAA (USA) and TCCA (Canada)

• Agreement: FAA-TCCA Maintenance Implementation Procedures (MIP)
• Recognition: Canada and the U.S. mutually accept each other’s Part 145/AMO certifications with minor additional oversight.

FAA (USA) and CAAC (China)

• Agreement: FAA-CAAC Bilateral Agreement
• Recognition: While CAAC does not fully recognize FAA Part 145 repair stations, U.S. repair stations can apply for CAAC maintenance approval under specific guidelines.

EASA (Europe) and UK CAA (United Kingdom)

• Agreement: Post-Brexit UK-EASA Working Arrangements
• Recognition: UK CAA no longer automatically recognizes EASA approvals. UK repair stations must obtain UK Part 145 certification separately.

EASA and TCCA (Canada)

• Agreement: EASA-TCCA BASA
• Recognition: EASA and TCCA allow reciprocal validation of repair station approvals.

FAA (USA) and ANAC (Brazil)

• Agreement: FAA-ANAC BASA
• Recognition: FAA and ANAC recognize each other’s repair station certifications but require additional procedural compliance.

EASA and CAAC (China)

• Agreement: EASA-CAAC Working Arrangement
• Recognition: CAAC does not fully accept EASA Part 145 certifications, but EASA-certified MROs can apply for CAAC validation.

Key Takeaways

• Most major authorities (FAA, EASA, TCCA, ANAC) have bilateral agreements for streamlined certification.
• China (CAAC) and Russia (FATA) tend to have stricter, independent approval processes.
• The UK now requires independent approval for Part 145 repair stations post-Brexit.
• Repair stations must often apply for "Supplemental Approval" or Validation from foreign regulators to work on non-national aircraft.
