As an EU-based organisation, what airworthiness release certificate is acceptable from a UK-based production organisation for recertification of parts from “PROTOTYPE” to “NEW”, in case where the UK-based POA has previously issued an EASA Form 1 for “PROTOTYPE” part before the end of the transition period and the certification of the design takes place after the end of the transition period?
Any potential EASA Form-1 issued by a UKCAA POA holder on or after January 01, 2021 would have no legal value (“null and void”) as an authorized release certificate. See Q As a UK-based production organisation, do I need to hold an EASA POA (as Third Country Approval)?
In case the design is approved under an EASA DOA, the UK-based POA can issue a CAA Form 1 for “NEW” under the UK CAA POA approval. Additional clarification can be entered in block 12.
