UK-EU Transition

References to EU regulation or EU websites in our guidance will not be an accurate description of your obligations or rights under UK law.

Organisations may hold an approval from ANAC to maintain aircraft or engine 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?

See the Official Record Series 5, CAA Scheme of Charges (Airworthiness, Noise Certification and Aircraft and Aircraft Engine Emissions)

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

If the number of hours taken by the CAA to carry out its investigations in relation to the application exceeds the cost shown above, the applicant must pay an excess hourly charge. The CAA shall determine the excess hourly charge by taking the total number of excess hours taken by the CAA to complete the required investigations in relation to the application and multiplying that number of hours by an hourly charge, currently £209. The balance for the excess hourly charge (total hourly charge less initial charge already paid) is payable by the applicant to the CAA and will be invoiced to the applicant.

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 RBAC may request suspension of the approval at any time if the conditions of the approval are not met.
