Transport Canada Maintenance Approvals - Changes

Transfer of oversight of Transport Canada CAR 571 and CAR 573 Approval Held by Organisations that Hold Part 145 Approval

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

A Bilateral Agreement between EU and Transport Canada Civil Aviation (TCCA) was signed on 2 February 2012. 

The Bilateral Agreement means that NAA’s in Europe will undertake the oversight of organisations that hold EASA 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.

Organisations must be based in the UK and hold:

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


  • For changes made to approvals where A1/B1 ratings are to be added the application fee is £2,189.00.
  • For changes made to approvals where A2/B2/B3/C/D ratings are to be added the application fee is £2,189.00
  • Changes are subject to an annual continuation fee detailed in the UK CAA Scheme of Charges. 
  • TCAA will make a charge to the organisation.

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. 

Payments can be made by credit or debit card or by bank transfer or by a cheque made payable to the Civil Aviation Authority.

Processing time (On receipt of all required information)

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