EASA Part 21 Subpart G Production Organisations Approvals

Sofema Online provides a brief introduction to EASA Part 21 Subpart G Process and Privileges.

An EASA Part 21 Subpart G organization is an organization which has approval to manufacture aircraft parts and appliances in conformity with approved data.

The production organization certifies and releases the product on either Form 52 for a complete aircraft or EASA Form 1 for components.

Production Organisation Approvals (POAs) are managed by EASA in accordance with Subpart G of Regulation (EC) No 748/2012.

The agency is responsible for:

○ The Management of all applications from non-EU countries (or from an EU country upon request of that country) for production organization approvals (POA).
○ The issue of related certificates and their continued surveillance.
