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.

Organisations may hold an approval from Brazilian Aviation Authority ANAC to maintain aircraft or engines and propellers for aircraft that are registered on the Brazilian Aircraft Register.

A Memorandum of Understanding between UK and Brazil was signed on 2 December 2020.

The Memorandum of Understanding means that the UK CAA will undertake the oversight of organisations that hold UK Part 145 approval and RBAC 145 Approval.


Organisations must be based in the UK and hold:

  • A valid UK Part 145 approval.
  • A current RBAC 145 approval.

How much does it cost?

Approvals are subject to an annual fee detailed in the UK CAA Scheme of Charges. There are currently fees charged by ANAC for their processing of approvals granted under the bilateral arrangements.

You can find the applicable fee according to instructions on the ANAC website (National Civil Aviation Agency of Brazil).

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.

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

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

How long is it valid for?

Once granted, a RBAC Approval is valid for 24 months unless suspended, cancelled or revoked.

Applicants should be aware that the RBAC may request suspension of the approval at any time if the conditions of approval are not met.
