Show the text

APPROVED PRODUCTION ORGANISATIONS THAT APPLY FOR A CERTIFICATE OF AIRWORTHINESS The holder of a production organisation approval issued under Subpart G of Annex I (Part 21) to Regulation (EU) No 748/2012 should use EASA Form 52 (and not EASA Form 52B) when it uses its privileges under point 21.A.163(b) and applies for a certificate of airworthiness for an aircraft with a type certificate. This indicates to the competent authority that the production organisation utilises its privileges to apply for a certificate of airworthiness without further showing.

APPROVED PRODUCTION ORGANISATIONS THAT APPLY FOR A RESTRICTED CERTIFICATE OF AIRWORTHINESS The holder of a production organisation approval issued under Subpart G of Annex I (Part 21) to Regulation (EU) No 748/2012 should use EASA Form 52B (and not EASA Form 52) when it uses its privileges under point 21.A.163(b) and applies for a restricted certificate of airworthiness for an aircraft with a registered declaration of design compliance (declared aircraft). Only EASA Form 52B may be used for declared aircraft because references to the declaration are included in that form. The holder of a production organisation approval should include its approval number on EASA Form 52B and indicate that this is an approved organisation so that the competent authority is made aware that the production organisation utilises its privileges to apply for a restricted certificate of airworthiness without further showing.
