ments. 

(a) Each cargo and baggage compart-

ment must be construced of or lined 
with materials in accordance with the 
following: 

(1) For accessible and inaccessible 

compartments not occupied by pas-
sengers or crew, the material must be 
at least fire resistant. 

(2) Materials must meet the require-

ments in § 29.853(a)(1), (a)(2), and (a)(3) 
for cargo or baggage compartments in 
which— 

(i) The presence of a compartment 

fire would be easily discovered by a 
crewmember while at the crew-
member’s station; 

(ii) Each part of the compartment is 

easily accessible in flight; 

(iii) The compartment has a volume 

of 200 cubic feet or less; and 

(iv) Notwithstanding § 29.1439(a), pro-

tective breathing equipment is not re-
quired. 

(b) No compartment may contain any 

controls, wiring, lines, equipment, or 
accessories whose damage or failure 
would affect safe operation, unless 
those items are protected so that— 

(1) They cannot be damaged by the 

movement of cargo in the compart-
ment; and 

(2) Their breakage or failure will not 

create a fire hazard. 

(c) The design and sealing of inacces-

sible compartments must be adequate 
to contain compartment fires until a 
landing and safe evacuation can be 
made. 

(d) Each cargo and baggage compart-

ment that is not sealed so as to contain 
cargo compartment fires completely 
without endangering the safety of a 
rotorcraft or its occupants must be de-
signed, or must have a device, to en-
sure detection of fires or smoke by a 
crewmember while at his station and 
to prevent the accumulation of harm-
ful quantities of smoke, flame, extin-
guishing agents, and other noxious 
gases in any crew or passenger com-
partment. This must be shown in 
flight. 

(e) For rotorcraft used for the car-

riage of cargo only, the cabin area may 
be considered a cargo compartment 
and, in addition to paragraphs (a) 
through (d) of this section, the fol-
lowing apply: 

(1) There must be means to shut off 

the ventilating airflow to or within the 
compartment. Controls for this purpose 
must be accessible to the flight crew in 
the crew compartment. 

(2) Required crew emergency exits 

must be accessible under all cargo 
loading conditions. 

(3) Sources of heat within each com-

partment must be shielded and insu-
lated to prevent igniting the cargo.
