Issue of new FAR 145 Repair Station Certificate (EU / US Bilateral Agreement)

How to apply


Maintenance Organisations may hold an approval from the Federal Aviation Administration (FAA) to maintain aircraft or components for aircraft that are registered in the United States of America.

A Bilateral Agreement between the EU and the USA was signed on 3 May 2011. The Agreement means that the National Aviation Authorities (NAA’s) in Europe will undertake the oversight of organisations that hold EASA Part 145 approval and FAR 145 Repair Station Certification. The UK CAA will undertake the oversight of those organisations where the main base is in the UK.


  • Organisations must hold a valid EASA Part 145 approval.
  • Where approval for a Part 145 is being sought at the same time, the Part 145 approval must be in place before the FAR 145 Repair Station Certificate can be recommended.
  •  The organisation must be able to demonstrate a need to hold a FAA Repair Stations Certification and provide written evidence from intended customers of an intent to use the applicants services
  • At the time of submitting the FAA Form 8400-6 Pre Application Statement of Intent, the organisation must not have any open audit findings against the EASA Part 145.
