Role & Purpose of EASA Delegated Regulation 2019/897 Related to Cabin Certification

Introduction

EASA’s Comment – To better mitigate any safety risks due to selective investigations and to improve the effectiveness, transparency and predictability of the certification process, certain selection criteria should be provided to allow determining which compliance demonstrations should be verified by the Agency and how exhaustively.

• Based on the experience with those existing privileges and in order to reduce administrative burden, while considering the risks to aviation safety and environmental protection requirements, holders of design organisation approvals should also be entitled to certify certain major changes to type certificates and issue certain supplemental type certificates.
• In order to limit risks to aviation safety and having regard to environmental protection requirements, those new privileges should only relate to certification of major changes of a limited novelty and should be granted only to those holders who can correctly exercise those new privileges.
• The latter should be demonstrated through showing a satisfactory performance in previous similar major changes with the involvement of the Agency.

Part 21 – 21.A.15 identifies the following requirement:

• An application for a type-certificate or restricted type-certificate shall include, as a minimum:

o???Preliminary descriptive data of the product,

o???The intended use of the product and the

o???Kind of operations for which certification is requested.

• In addition, it shall include, or be supplemented after the initial application, a certification programme for the demonstration of compliance in accordance with point 21.A.20, consisting of:

o???A detailed description of the type design, including all the configurations to be certified;

o???The proposed operating characteristics and limitations;

o???The intended use of the product and the kind of operations for which certification is requested.
