All Part 21 aircraft types that qualify for an Part 21 Certificate of Airworthiness (C of A) are issued with a non-expiring C of A, which is validated annually with an Airworthiness Review Certificate (ARC).

This annual validation occurs when a new ARC is issued or the validity of a current ARC is extended.

Who can apply

• Continuing Airworthiness Management Organisations (CAMOs) that hold the appropriate Part M Subpart G approval
• Maintenance Organisations that hold a Part M Subpart F or Part 145 approval with approval to carry out airworthiness reviews on ELA1 aircraft
• Engineers that hold a European Light Aircraft (ELA) approval

Note: ARC privileges and an ARC Online login is provided to your UK, CAA-approved organisation once a Part M Subpart G, Part M Subpart F or Part 145 initial approval or variation is completed and the approval certificate is issued.

Please refer to the following two flow charts for guidance on which type of application to make:
