For how long is a type-certificate issued under Part 21 valid?

A type-certificate is issued for an unlimited duration, provided the holder remains in compliance with Annex 1 (Part 21) and the certificate is not surrendered or revoked under applicable Agency procedures.

What two conditions must be met for a restricted type-certificate to continue to remain valid?

The restricted type-certificate remains valid subject to: (1) the holder remaining in compliance with Annex 1 (Part 21), and (2) the certificate not being surrendered or revoked under the applicable administrative procedures established by the Agency.

What must the holder do with a type-certificate if it is surrendered or revoked?

Upon surrender or revocation, the type-certificate (or restricted type-certificate) must be returned to the Agency.

Does a type-certificate automatically expire after a fixed number of years?

No, a type-certificate is issued for an unlimited duration. It does not expire after a fixed number of years; it remains valid as long as the holder stays in compliance with Part 21 and the certificate is not surrendered or revoked.

Under which regulation is the duration and continued validity of type-certificates specified?

The duration and continued validity of type-certificates is specified under Regulation (EU) No 748/2012, specifically in section 21.A.51 of Annex 1 (Part 21).

What happens to a restricted type-certificate if the holder fails to remain in compliance with Part 21?
