ED Decision 2023/013/R
VOLUNTARY INVOLVEMENT OF THE AGENCY PRIOR TO THE SUBMISSION OF THE DECLARATION
The declarant may choose to involve EASA prior to submitting the declaration of design compliance. This would allow EASA to:
(a) check that the product is within the scope of Subpart C;
(b) provide guidance on the completeness of the compliance-demonstration plan and the selection of the means of compliance;
(c) provide guidance on the selection of the applicable detailed technical specifications and applicable noise requirements;
(d) provide guidance about and witnessing and participating to noise tests;
(e) avoid any issues or delays during the first-article inspection (after submission of the declaration of design compliance).
The initiation of the project by the declarant by submitting a request to EASA may occur before starting the compliance activities or during those activities. The assignment of a dedicated project number would facilitate any subsequent communication with EASA. This will facilitate the provision of compliance documentation required by point 21L.A.43(c) which can be provided by the declarant to EASA at key stages in the compliance demonstration prior to submission of the declaration of design compliance.
The declarant should also request access to EASAâs Part 21 Light database of declared noise levels referring to the given Agency project number[66] in order to provide the required data under point 21L.A.43(b)(11) (see AMC1 21L.A.43(b)).
In accordance with point 21L.B.61, the environmental protection requirements are defined in Regulation (EU) 2018/1139 to be those contained in Annex 16 to the Chicago Convention. As regards aircraft noise, noise testing is generally conducted making use of technical and equivalent procedures that are described in ICAO Doc 9501 âEnvironmental Technical Manualâ, Volume I âProcedures for the Noise Certification of Aircraftâ. The use of such procedures demands a deeper knowledge of the environmental protection requirements. In case of doubt and to minimise the risk of any re-test after the first-article inspection, the declarant is encouraged to contact EASA well before the noise flight test.
[66] The access to the Agencyâs Part 21 Light database of declared noise levels will be granted when the declarant initiates their first Part 21 Light declared project at EASA. Access to this database will also enable the declarant to use this database for future projects.
