The organisation will need to send the following to their Federal Aviation Administration (FAA) supervising Flight Standards District Office (FSDO):

• A correctly completed Part 145 Approved Maintenance Organisation application form (SRG1783).
• An amendment to their CAA supplement.

An application for a change to a UK Part 145 approval certificate will need to be made for any of the following changes to the Federal Aviation Administration (FAA) repair station certificate:

• A change of name, including a change to the ‘doing business as’ name.
• A change of the address of the fixed location of the facility (this does not include the mailing address).
• A change of the repair station certificate number.

An application will also need to be made for any of the following changes, but such changes will not result in an amendment to the UK Part 145 approval certificate:

• A change in Accountable Manager
• Additional fixed locations
• Additional line stations
• A change in ratings

Full details of changes requiring an application can be found in Section B, paragraph 4 of Maintenance Agreement Guidance (CAP1780MAG).

The FAA will inform the Civil Aviation Authority (CAA) of the proposed change by email within 10 working days of the application being received.

Following the satisfactory outcome of any required audit by the FAA, the FAA shall recommend acceptance of the changes to the (UK) Part-145 approval.

When a positive recommendation for a change to the approval has been received from the Federal Aviation Administration (FAA), the new approval certificate will be raised and sent to your organisation within 10 working days.

The information below provides guidance on what to expect during the process:

The Federal Aviation Administration (FAA) will review the application form and document package, carry out any audits as necessary, and when satisfactory, make a recommendation to the Civil Aviation Authority (CAA) to issue the approval.

Upon receipt of a completed recommendation from the FAA, the CAA shall review the application for compliance with the Maintenance Implementation Procedures (MIP) and Maintenance Agreement Guidance (MAG). When satisfied with the contents of the application, the CAA will issue a revised certificate to the repair station. The CAA will also send a copy to the FAA and update the CAA website.

Once granted, a UK Part 145 approval requires a recommendation for continuation of the approval every 24 months from the date of initial issue. This is raised by the Federal Aviation Administration (FAA) and sent to the Civil Aviation Authority (CAA) following a satisfactory audit programme.
