UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.

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 UK and the USA was signed on 20 December 1995. The Agreement means that the UK Civil Aviation Authority (CAA) will undertake the oversight of organisations that hold UK Part 145 approval and FAR 145 Repair Station Certification.


Organisations must:

  • hold a valid UK Part 145 approval
  • be able to demonstrate a continuing need to hold a FAA Repair Station Certification and provide written evidence of work that has been carried out over the past 12 or 24 months
  • submit their application for renewal 90 days before the expiry date of the FAR 145 Repair Station Certificate. (Applications received after the 90 day deadline may be rejected as there may be insufficient time to carry out the renewal process)
