propeller is in reverse pitch, that com-
plies with the following:

§ 121.308 Lavatory fire protection.

(a) Except as provided in paragraphs

(c) and (d) of this section, no person
may operate a passenger-carrying air-
plane unless each lavatory in the air-
plane is equipped with a smoke detec-
tor system or equivalent that provides
a warning light in the cockpit or pro-
vides a warning light or audio warning
in the passenger cabin which would be
readily detected by a flight attendant,
taking into consideration the posi-

tioning of flight attendants throughout
the passenger compartment during var-
ious phases of flight.

(b) Except as provided in paragraph

(c) of this section, no person may oper-
ate a passenger-carrying airplane un-
less each lavatory in the airplane is
equipped with a built-in fire extin-
guisher for each disposal receptacle for
towels, paper, or waste located within
the lavatory. The built-in fire extin-
guisher must be designed to discharge
automatically into each disposal recep-
tacle upon occurrence of a fire in the
receptacle.

cate holder described in § 121.2(a) (1) or
(2) may operate an airplane with a pas-
senger seat configuration of 30 or fewer
seats that does not comply with the
smoke detector system requirements
described in paragraph (a) of this sec-
tion and the fire extinguisher require-
ments described in paragraph (b) of
this section.

(d) After December 22, 1997, no person

may operate a nontransport category
airplane type certificated after Decem-
ber 31, 1964, with a passenger seat con-
figuration of 10–19 seats unless that
airplane complies with the smoke de-
tector system requirements described
in paragraph (a) of this section, except
that the smoke detector system or
equivalent must provide a warning
light in the cockpit or an audio warn-
ing that would be readily detected by
the flightcrew.

Hand fire extinguishers for crew,

passenger, cargo, and galley compart-
ments.

Hand fire extinguishers of an ap-

proved type must be provided for use in
crew, passenger, cargo, and galley com-
partments in accordance with the fol-
lowing:

(1) The type and quantity of extin-

guishing agent must be suitable for the
kinds of fires likely to occur in the
compartment where the extinguisher is
intended to be used and, for passenger
compartments, must be designed to
minimize the hazard of toxic gas con-
centrations.

(6) Notwithstanding the requirement

for uniform distribution of hand fire
extinguishers as prescribed in para-
graph (c)(5) of this section, for those
cases where a galley is located in a pas-
senger compartment, at least one hand
fire extinguisher must be conveniently
located and easily accessible for use in
the galley.

(7) At least two of the required hand

fire extinguisher installed in pas-
senger-carrying airplanes must contain
Halon 1211

lent as the extinguishing agent. At
least one hand fire extinguisher in the
passenger compartment must contain
Halon 1211 or equivalent.

(d) [Reserved]
(e)

Crash ax.

rying airplane must have a portable
battery-powered megaphone or mega-
phones readily accessible to the crew-

evacuation, installed as follows:

(1) One megaphone on each airplane

with a seating capacity of more than 60
and less than 100 passengers, at the
most rearward location in the pas-
senger cabin where it would be readily
accessible to a normal flight attendant
seat. However, the Administrator may
grant a deviation from the require-
ments of this subparagraph if he finds
that a different location would be more
useful for evacuation of persons during
an emergency.

(2) Two megaphones in the passenger

cabin on each airplane with a seating
capacity of more than 99 passengers,
one installed at the forward end and
the other at the most rearward loca-
tion where it would be readily acces-

§ 121.310 Additional emergency equip-

ment.

(a)

Means for emergency evacuation.

Each passenger-carrying landplane
emergency exit (other than over-the-
wing) that is more than 6 feet from the
ground with the airplane on the ground
and the landing gear extended, must
have an approved means to assist the
occupants in descending to the ground.
The assisting means for a floor-level
emergency exit must meet the require-
ments of § 25.809(f)(1) of this chapter in
effect on April 30, 1972, except that, for
any airplane for which the application
for the type certificate was filed after
that date, it must meet the require-
ments under which the airplane was
type certificated. An assisting means
that deploys automatically must be
armed during taxiing, takeoffs, and
landings. However, if the Adminis-
trator finds that the design of the exit
makes compliance impractical, he may
grant a deviation from the requirement
of automatic deployment if the assist-
ing means automatically erects upon
deployment and, with respect to re-
quired emergency exits, if an emer-
gency evacuation demonstration is
conducted in accordance with
§ 121.291(a). This paragraph does not
apply to the rear window emergency
exit of DC–3 airplanes operated with
less than 36 occupants, including crew-
members and less than five exits au-
thorized for passenger use.

(b)

Interior emergency exit marking.

The following must be complied with
for each passenger-carrying airplane:

(1) Each passenger emergency exit,

its means of access, and its means of
opening must be conspicuously
marked. The identity and location of
each passenger emergency exit must be
recognizable from a distance equal to
the width of the cabin. The location of
each passenger emergency exit must be
indicated by a sign visible to occupants
approaching along the main passenger
aisle. There must be a locating sign—

(i) Above the aisle near each over-

the-wing passenger emergency exit, or

at another ceiling location if it is more
practical because of low headroom;

(ii) Next to each floor level passenger

emergency exit, except that one sign
may serve two such exits if they both
can be seen readily from that sign; and

(iii) On each bulkhead or divider that

prevents fore and aft vision along the
passenger cabin, to indicate emergency
exits beyond and obscured by it, except
that if this is not possible the sign may
be placed at another appropriate loca-
tion.

(2) Each passenger emergency exit

marking and each locating sign must
meet the following:

(i) Except as provided in paragraph

(b)(2)(iii) of this section, for an air-
plane for which the application for the
type certificate was filed prior to May
1, 1972, each passenger emergency exit
marking and each locating sign must
be manufactured to meet the require-
ments of § 25.812(b) of this chapter in ef-
fect on April 30, 1972. On these air-
planes, no sign may continue to be
used if its luminescence (brightness)
decreases to below 100 microlamberts.
The colors may be reversed if it in-
creases the emergency illumination of
the passenger compartment. However,
the Administrator may authorize devi-
ation from the 2-inch background re-
quirements if he finds that special cir-
cumstances exist that make compli-
ance impractical and that the proposed
deviation provides an equivalent level
of safety.

(ii) For a transport category airplane

for which the application for the type
certificate was filed on or after May 1,
1972, each passenger emergency exit
marking and each locating sign must
be manufactured to meet the interior
emergency exit marking requirements
under which the airplane was type cer-
tificated. On these airplanes, no sign
may continue to be used if its lumines-
cence (brightness) decreases to below
250 microlamberts.

(iii) For a nontransport category

turbopropellerpowered airplane type
certificated after December 31, 1964,
each passenger emergency exit mark-
ing and each locating sign must be
manufactured to have white letters 1
inch high on a red background 2 inches
