14 CFR Ch. I (1–1–19 Edition) 

§ 25.813 

an assist space must be provided, if an 
assist means is required by § 25.810(a). 

(6) There must be a handle, or han-

dles, at each assist space, located to 
enable the crewmember to steady him-
self or herself: 

(i) While manually activating the as-

sist means (where applicable) and, 

(ii) While assisting passengers during 

an evacuation. 

(c) The following must be provided 

for each Type III or Type IV exit—(1) 
There must be access from the nearest 
aisle to each exit. In addition, for each 
Type III exit in an airplane that has a 
passenger seating configuration of 60 or 
more— 

(i) Except as provided in paragraph 

(c)(1)(ii), the access must be provided 
by an unobstructed passageway that is 
at least 10 inches in width for interior 
arrangements in which the adjacent 
seat rows on the exit side of the aisle 
contain no more than two seats, or 20 
inches in width for interior arrange-
ments in which those rows contain 
three seats. The width of the passage-
way must be measured with adjacent 
seats adjusted to their most adverse 
position. The centerline of the required 
passageway width must not be dis-
placed more than 5 inches horizontally 
from that of the exit. 

(ii) In lieu of one 10- or 20-inch pas-

sageway, there may be two passage-
ways, between seat rows only, that 
must be at least 6 inches in width and 
lead to an unobstructed space adjacent 
to each exit. (Adjacent exits must not 
share a common passageway.) The 
width of the passageways must be 
measured with adjacent seats adjusted 
to their most adverse position. The un-
obstructed space adjacent to the exit 
must extend vertically from the floor 
to the ceiling (or bottom of sidewall 
stowage bins), inboard from the exit for 
a distance not less than the width of 
the narrowest passenger seat installed 
on the airplane, and from the forward 
edge of the forward passageway to the 
aft edge of the aft passageway. The exit 
opening must be totally within the fore 
and aft bounds of the unobstructed 
space. 

(2) In addition to the access— 
(i) For airplanes that have a pas-

senger seating configuration of 20 or 
more, the projected opening of the exit 

provided must not be obstructed and 
there must be no interference in open-
ing the exit by seats, berths, or other 
protrusions (including any seatback in 
the most adverse position) for a dis-
tance from that exit not less than the 
width of the narrowest passenger seat 
installed on the airplane. 

(ii) For airplanes that have a pas-

senger seating configuration of 19 or 
fewer, there may be minor obstructions 
in this region, if there are compen-
sating factors to maintain the effec-
tiveness of the exit. 

(3) For each Type III exit, regardless 

of the passenger capacity of the air-
plane in which it is installed, there 
must be placards that— 

(i) Are readable by all persons seated 

adjacent to and facing a passageway to 
the exit; 

(ii) Accurately state or illustrate the 

proper method of opening the exit, in-
cluding the use of handholds; and 

(iii) If the exit is a removable hatch, 

state the weight of the hatch and indi-
cate an appropriate location to place 
the hatch after removal. 

(d) If it is necessary to pass through 

a passageway between passenger com-
partments to reach any required emer-
gency exit from any seat in the pas-
senger cabin, the passageway must be 
unobstructed. However, curtains may 
be used if they allow free entry 
through the passageway. 

(e) No door may be installed between 

any passenger seat that is occupiable 
for takeoff and landing and any pas-
senger emergency exit, such that the 
door crosses any egress path (including 
aisles, crossaisles and passageways). 

(f) If it is necessary to pass through a 

doorway separating any crewmember 
seat (except those seats on the 
flightdeck), occupiable for takeoff and 
landing, from any emergency exit, the 
door must have a means to latch it in 
the open position. The latching means 
must be able to withstand the loads 
imposed upon it when the door is sub-
jected to the ultimate inertia forces,
