How does a restricted certificate of airworthiness under Part 21 Light differ from one issued under Annex I (Part 21) to Regulation (EU) No 748/2012?

A restricted certificate of airworthiness under Part 21 Light is based on a declaration of design compliance in accordance with Subpart C of Annex Ib, whereas a restricted certificate of airworthiness under Annex I (Part 21) to Regulation (EU) No 748/2012 is issued under a different regulatory framework and should not be confused with the Part 21 Light process.

Under what circumstances might EASA have deregistered a declaration of design compliance, and what is the consequence?

EASA may have temporarily or permanently deregistered the declaration of design compliance if an issue affecting safety is discovered in accordance with point 21L.B.22(a)(9). This would prevent the issuance of a restricted certificate of airworthiness until the registration is restored.

Q: What is the legal basis for issuing a restricted certificate of airworthiness for an individual aircraft under Part 21 Light?

A restricted certificate of airworthiness is issued for individual aircraft that conform to a design that has been subject to a declaration of design compliance in accordance with Subpart C of Annex Ib (Part 21 Light), as per Article 18(2)(a) of Regulation (EU) 2018/1139.

Q: What does the phrase 'registered by the Agency in accordance with point 21L.B.63 at the time of application' mean for a declaration of design compliance?

It means that the declaration of design compliance is registered and published on the EASA website, or registered in a repository for declarations of design compliance, at the time of the application for a restricted certificate of airworthiness.

Q: After a joint first-article inspection, what potential delay might occur, and how can the competent authority of the Member State of registry address it?

There could be a short delay in EASA conducting the necessary administrative actions to register the declaration of design compliance after the joint first-article inspection. To avoid delays in issuing the first restricted certificate of airworthiness, the competent authority of the Member State of registry may directly contact EASA to confirm that there are no outstanding actions preventing the registration, thereby enabling issuance.

Q: Which points in Part 21 Light specify the joint first-article inspection requirements for EASA and the competent authority of the Member State of manufacture?

EASA conducts the joint first-article inspection in accordance with point 21L.B.62(b), and the competent authority of the Member State of manufacture conducts it in accordance with either point 21L.B.143(b) or point 21L.B.251(b).

GM1 21L.B.162(b) Issuance or amendment of a certificate of airworthiness or a restricted certificate of airworthiness

ED Decision 2023/013/R

In accordance with Article 18(2)(a) of Regulation (EU) 2018/1139, a restricted certificate of airworthiness is issued for individual aircraft that conform to a design that has been subject to a declaration of design compliance in accordance with Subpart C of Annex Ib (Part 21 Light). This should not be confused with a restricted certificate of airworthiness issued under Annex I (Part 21) to Regulation (EU) No 748/2012.

The term ‘registered by the Agency in accordance with point 21L.B.63 at the time of application’ means that the declaration of design compliance is registered and published on the EASA website, or registered in a repository for declarations of design compliance at the time of the application.

The competent authority should ensure that the relevant declaration of design compliance is still registered by EASA prior to issuing a restricted certificate of airworthiness. It is possible that EASA has either temporarily or permanently deregistered the declaration of design compliance in the event of discovering an issue that affects safety in accordance with point 21L.B.22(a)(9).

Following the joint first-article inspection conducted by EASA in accordance with point 21L.B.62(b) and the competent authority of the Member State of manufacture in accordance with either point 21L.B.143(b) or point 21L.B.251(b), it is possible that there could be a short delay in EASA conducting the necessary administrative actions to register the declaration of design compliance. In the interim, and to avoid any delays in issuing the first restricted certificate of airworthiness, the competent authority of the Member State of registry may directly contact EASA to confirm that there are no outstanding actions preventing the registration of the declaration of design compliance thereby enabling the competent authority of the Member State of registry to issue the first restricted certificate of airworthiness.
