EASA Part 21 & CAR 21 Subpart G & J Regulatory Framework – 3 Days


Subpart J regulatory approval provides for the Design of Aircraft and Components Design Organisation Approval (DOA) and Subpart G provides for a Production Organization approval (POA).

The primary function of the DOA holder is to assume full responsibility for all designed products (Initial Airworthiness) including the need to support Continued Airworthiness of the designed product.

Whilst the role of the POA relates in part to the role of (Continued Airworthiness) the primary function of the organization is Initial Airworthiness in respect of managing the production of Products Parts and Appliances for use on aircraft, the process is regulated in accordance with the requirements of Part 21.

A company holding Part-21 (CAR 21) Subpart J Design Organisation Approval (DOA), has the approval to Design and certify aircraft parts.

A company holding Part-21 (CAR 21) Subpart G Production Organisation Approval (POA), has the approval to build and certify aircraft parts when a DOA -POA agreement is in place.

Organizations approved to manufacture in accordance with PART 21 (CAR 21 Subpart G are approved to issue EASA Form One or GCAA Form 1 as appropriate in respect of the Products Parts and Appliances.
