Section 25.813

14 CFR Ch. I (1-1-19 Edition)

an assist space must be provided, if an
assist means is required by Section 25.810(a).
(6) There must be a handle, or handles, at each assist space, located to
enable the crewmember to steady himself or herself:
(i) While manually activating the assist 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 arrangements in which those rows contain
three seats. The width of the passageway must be measured with adjacent
seats adjusted to their most adverse
position. The centerline of the required
passageway width must not be displaced more than 5 inches horizontally
from that of the exit.
(ii) In lieu of one 10- or 20-inch passageway, there may be two passageways, 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 unobstructed 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 passenger seating configuration of 20 or
more, the projected opening of the exit

provided must not be obstructed and
there must be no interference in opening the exit by seats, berths, or other
protrusions (including any seatback in
the most adverse position) for a distance from that exit not less than the
width of the narrowest passenger seat
installed on the airplane.
(ii) For airplanes that have a passenger seating configuration of 19 or
fewer, there may be minor obstructions
in this region, if there are compensating factors to maintain the effectiveness of the exit.
(3) For each Type III exit, regardless
of the passenger capacity of the airplane 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, including the use of handholds; and
(iii) If the exit is a removable hatch,
state the weight of the hatch and indicate an appropriate location to place
the hatch after removal.
(d) If it is necessary to pass through
a passageway between passenger compartments to reach any required emergency exit from any seat in the passenger 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 passenger 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 subjected to the ultimate inertia forces,
