EASA Approval of Minor Changes

Approval of Minor Changes to UK Registered Aircraft Regulated by EASA

Due to the implementation of European Regulation (EC) No. 1702/2003 it has become necessary to change the processes for the approval of minor changes and repairs to aircraft regulated by EASA (EASA aircraft).

  • CAP 747 - "Mandatory Requirements for Airworthiness" contains the specific list of EASA and non-EASA aircraft.

 


 

The procedure for the approval of minor changes and repairs is now as follows:

Minor changes and repairs designed by organisations that hold an appropriate Part 21 Design Organisation Approval will be approved under the procedures of those organisations.

For the approval of all other minor changes and repairs designed in the UK for EASA aircraft, EASA Form 32 should be sent to EASA.

Where the technical investigation has been allocated to the CAA by EASA, the change or repair will be assessed by a CAA Surveyor at Aviation House. (Where a particular investigation requires an inspection of the aircraft and/or its records, the inspection will be performed by the appropriate Regional Office Surveyor and a report sent to Aviation House).

If the result of the investigation is satisfactory, the Surveyor at Aviation House will recommend to EASA that it approves the change or repair. The applicant will subsequently receive an approval certificate from EASA.

If the minor change or repair is designed in another EU member state and has EASA approval, it can be installed on a UK registered EASA aircraft without the need to seek further approval.

Aircraft not subject to EASA regulation

The procedures for the approval of minor modifications and repairs to aircraft that are not subject to regulation by EASA are not affected by these changes. Applications for the approval of minor modifications and repairs to non-EASA aircraft should continue to be made to the appropriate CAA Regional Office.
