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.
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 EU and the USA was
signed on 3 May 2011.
The Bilateral Agreement means that the National Aviation Authorities (NAA’s) in Europe will undertake the oversight
of organisations that hold EASA Part 145 approval and FAR 145 Repair Station Certification.
The UK CAA will undertake the oversight of those organisations where the main base is in the UK.
Organisations must hold a valid EASA Part 145 approval
Changes must be made coincidentally to EASA Part 145 and FAR 145 approvals
The EASA Part 145 scope of approval and the FAR 145 Ops Spec must remain synchronised, therefore you will also need
to apply for a variation to your EASA Part 145 approval (see: Change an Existing EASA Part 145 Approval for further information
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
Payments can be made by credit or debit card or by bank transfer.
We will confirm receipt of your application within 10 working days.
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.
