UK – EU Transition, and UK Civil Aviation Regulations

To access current UK civil aviation regulations, including AMC and GM, CAA regulatory documents, please use this link to UK Regulation. Please note, if you use information and guidance under the Headings below, the references to EU regulations or EU websites in our guidance will not be an accurate information or description of your obligations under UK law. These pages are undergoing reviews and updates.

Organisations may hold an approval from Transport Canada Civil Aviation (TCCA) to maintain aircraft registered on the Canadian Aircraft Register.

A Working Arrangement between UK CAA and Transport Canada Civil Aviation (TCCA) was signed on 5 November 2020.

The Working Arrangement means that UK CAA will undertake the oversight of organisations that hold UK Part 145 approval and TCCA CAR 571 and 573 Approval. This means that the UK CAA will undertake the oversight of those organisations where the main base is in the UK.

Transition Arrangements

UK Organisations holding aircraft rated TCCA approvals prior to the 31/12/2020, will need to apply for an initial TCCA approval at least 90 days prior to the expiry date of their current approval letter, to enable transition and continuation under the new Working Arrangement. Failure to apply for your approval to transition, will result in the expiry of your TCCA approval.


Organisations must be based in the UK and hold:

  • A valid UK Part 145 approval.
  • A current TCCA CAR 571/573 approval.

How much does it cost?

  • For organisations maintaining aircraft weighing 5700kg or more the initial application fee is £1720.
  • For organisations maintaining aircraft weighing 5700kg or less the fee is £1290.
  • Approvals are subject to an annual continuation fee detailed in the UK CAA Scheme of Charges.

In the event of a discrepancy between the information here and the Official Record Series 5, CAA Scheme of Charges (Airworthiness, Noise Certification and Aircraft and Aircraft Engine Emissions), the Scheme of Charges takes precedence.

How long will it take for my application to be processed?

  • The application will be processed by Applications & Approvals (A&A) and forwarded to the CAA Regional Office for review within 10 working days.

How long is it valid for?

  • Once granted, a TCCA Approval is non-expiring unless suspended, cancelled or revoked.
  • Applicants should be aware that TCCA may request suspension of the approval at any time if the conditions of approval are not met.
