Appendix S, S25.10(b) Interior Doors on Commercially Operated Aeroplanes
ED Decision 2017/015/R
In the case of an aeroplane which is not intended to be
limited to non-commercial operations, the familiarity of the occupants with
the specific cabin features of the aeroplane cannot be credited in the demonstration
that, in the case of any probable failure or jamming of the door in a position
other than fully open, any occupant is able, from any compartment separated by
that door, to restore in an easy and simple manner a sufficient opening to
access the compartment on the other side of the door (compliance with the
condition S25.10(a)(3)); this
means, for instance, that when the demonstration relies on the frangibility of
the door, there should be a placard on each side of the door to indicate the
presence and functioning of this feature.
The requirement S25.10(b)(2)(ii) states that ‘the demonstration of
compliance against the provision S25.10(a)(1) and (2) shall not rely on any
passenger action, nor involve any flight crew member leaving their position in
the cockpit’. Any of the following solutions may be employed to meet this
requirement:
(1) An
automatic system, for the opening of the door and retention of the door in the
open and secured position.
(2) A
control in the cockpit, compliant with CS 25.777, to activate
remotely the opening of the door and retention of the door in the open and
secured position.
(3) For aeroplanes required to have at least one cabin crew member on board, and the cabin crew is clearly tasked with ensuring that the door is open before entering any of the taxiing, take-off, and landing phases. Appropriate cabin crew procedures and cabin crew training should be established.
