§ 23.1411
General.
(a) Required safety equipment to be
used by the flight crew in an emer-
gency, such as automatic liferaft re-
leases, must be readily accessible.
(b) Stowage provisions for required
safety equipment must be furnished
and must—
(1) Be arranged so that the equip-
ment is directly accessible and its loca-
tion is obvious; and
(2) Protect the safety equipment
from damage caused by being subjected
to the inertia loads resulting from the
ultimate static load factors specified in
§ 23.561(b)(3) of this part.

§ 23.1415
Ditching equipment.
(a) Emergency flotation and sig-
naling equipment required by any oper-
ating rule in this chapter must be in-
stalled so that it is readily available to
the crew and passengers.
(b) Each raft and each life preserver
must be approved.
(c) Each raft released automatically
or by the pilot must be attached to the
airplane by a line to keep it alongside
the airplane. This line must be weak
enough to break before submerging the
empty raft to which it is attached.
(d) Each signaling device required by
any operating rule in this chapter,
must be accessible, function satisfac-
torily, and must be free of any hazard
in its operation.
§ 23.1416
Pneumatic de-icer boot sys-
tem.
If certification with ice protection
provisions is desired and a pneumatic
de-icer boot system is installed—
(a) The system must meet the re-
quirements specified in § 23.1419.
(b) The system and its components
must be designed to perform their in-
tended function under any normal sys-
tem operating temperature or pressure,
and
(c) Means to indicate to the flight
crew that the pneumatic de-icer boot
system is receiving adequate pressure
and is functioning normally must be
provided.

§ 23.1419
Ice protection.
If certification with ice protection
provisions is desired, compliance with
the requirements of this section and
other applicable sections of this part
must be shown:
(a) An analysis must be performed to
establish, on the basis of the airplane’s
operational needs, the adequacy of the
ice protection system for the various
components of the airplane. In addi-
tion, tests of the ice protection system
must be conducted to demonstrate that
the airplane is capable of operating
safely in continuous maximum and
intermittent maximum icing condi-
tions, as described in appendix C of
part 25 of this chapter. As used in this
section, ‘‘Capable of operating safely,’’
means that airplane performance, con-
trollability, maneuverability, and sta-
bility must not be less than that re-
quired in part 23, subpart B.
