This page provides details of how holders of a UK Part 145 approval can change their FAR 145 repair station approval (if applicable).

Pre-requisites

Organisations must hold a valid UK Part 145 approval.
Changes that affect the Federal Aviation Administration (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 do I apply?

You will need to complete and submit the online application form.

What do I need to include with my application?

You will need to include the following information with your application:

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

The CAA 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.

How much does it cost?



The charge for A1/B1 ratings is £1,421.

The charge of A2/B2/B3/C/D ratings is £1,063.

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 to change an Existing Part 145 Approval for a variation to your Part 145 approval.

In the event of a discrepancy between the information here and the Official Record Series 5, Civil Aviation Authority (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 card, debit card or by bank transfer.
