Sofema Aviation Services (SAS) www.sassofia.com considers the changes related to the Cabin certification of EASA Compliant Aircraft Minor & Major Cabin Modifications.
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.
Part 21.A.20 Demonstration of compliance
Demonstration of compliance with:
- The type certification basis,
- Operational suitability data certification basis and
- Environmental protection requirements.
Regulation (EU) 2019/897 – Following the acceptance of the certification programme by the Agency, the applicant shall demonstrate compliance with the type certification basis, operational suitability data certification basis and environmental protection requirements.
- The applicant shall report to the Agency any difficulty or event encountered during the process of demonstration of compliance that may have an appreciable effect on:
o The risk assessment under point 21.A.15,
o Or on the certification programme,
o Or may otherwise necessitate a change to the level of involvement.
- The applicant shall record justifications of compliance within the compliance documents as referred to in the certification programme.
- After completion of all demonstrations of compliance in accordance with the certification programme, including any inspections and tests in accordance with point 21.A.33, and after all flight tests in accordance with point 21.A.35, the applicant shall declare that:
o It has demonstrated compliance with the type-certification basis,
o Operational suitability data certification basis and
o Environmental protection requirements, and
o No feature or characteristic has been identified that may make the product unsafe for the uses for which certification is requested.
