The aircraft's own certificate

The certificate of airworthiness belongs to one aircraft. The type certificate behind it approves the design. This point is the procedure for the individual certificate.

21.A.171 (full rule text)Scope

This Subpart establishes the procedure for issuing airworthiness certificates to aircraft which conform to a type certificate that has been issued in accordance with this Annex.

Quoted word for word from Regulation (EU) No 748/2012, Easy Access Rules for Initial Airworthiness, 27 Nov 2025 revision.

The certificate is issued to an aircraft that conforms to a type certificate issued under this Annex. This guide is the application, what moves with the aircraft while it stays on the same register, and the permit to fly.
