Improvement in the survivability of rotorcraft occupants in the event of a crash — Phase 1 – Crash resistant fuel systems
Submit your comments via CRT

The objective of this Notice of Proposed Amendment (NPA) is to mitigate the risks linked to a post-crash fire involving a rotorcraft.

This NPA proposes to mandate the installation of a crash-resistant fuel system (CRFS) onto existing rotorcraft designs that are still in production and the retrofit of existing rotorcraft that are operated in the EASA Member States.

Several accident investigation boards put forward safety recommendations (SRs) on the lack of CRFSs for rotorcraft that had been certified before the significant improvements of the rules for fuel system crash resistance were introduced in the 1990s.

The proposed amendments are expected to increase safety and improve the survivability of rotorcraft occupants by significantly reducing the likelihood of a post-crash fire.
