Cabin safety: Where can we find samples of STC for zero-passenger cabin layouts?
EASA cannot disclose technical property information. EASA has approved several zero-passenger layouts from different applicants but data belong to the Approval Holders.
When do you plan to release CSXXX for smoke propagation and smoke penetration?
There will be no new Certification Specification but instead a Certification Memorandum (CM). The CM is in the final phase and please check the EASA CM webpage for status.
Covers replacement in 16g seats: is it required to perform certification tests to demonstrate compliance with 25.562?
EASA is accepting the guidance of FAA AC-25.562-1b; dress covers do not require normally dynamic testing. Cushion changes would at least require 14g downward testing.
