EASA Part 21 Subpart J High – Level Review – 1 Day


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 Subpart J Design Organisation Approval (DOA), has the approval to Design and certify aircraft parts.
