Please note that, in the event of UK participation in EASA and mutual recognition of licences and certificates ceasing, some CAA website content and application forms may continue to carry the EASA logo or reference the EU or EASA rather than the UK CAA in the short term.
These will be updated in due course following the outcome of the transition period negotiations on the long-term aviation relationship between the UK and the EU. In the meantime, the guidance provided and the application forms accessed via the CAA website portal will continue to be valid
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 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.
Changes that affect the FAA Certificate and/or OpSpecs, as detailed within the Maintenance Agreement Guidance, a formal FAA application is required. (The FAA Certificate and/or OpSpecs will not exceed the ratings or scope of work under your Part 145 approval).
How much does it cost?
- The charge for A1.B1 ratings is £1,183
- The charge of A2/B2/B3/C/D ratings is £538
The FAA Certificate and/or OpSpecs will not exceed the ratings or scope of work under your Part 145 approval. Therefore, you will also need to apply for a variation to your Part 145 approval (see: Change an Existing Part 145 Approval for further information and 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.
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. 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.
How long will it take for my application to be processed?
We will confirm receipt of your application within 10 working days.
How long is it valid for?
Unless expired, revoked, suspended or cancelled FAR 145 Repair Station Certificates are valid for 12 months following initial approval and then valid for 24 months after the first renewal.
