The lower passenger/crew door has a cable
that is used to pull the door closed from the
inside. A secondary latch, located on the for-
ward door frame engages a catch on the upper
forward corner of the lower door, when the
door is closed. The tab on this spring loaded
latch has to be raised to open the lower door.
This door is also equipped with gas dampers
for opening and closing. When fully open, the
door is supported by stops within the dampers.
A rubber seal fastened around the main door
frame allows pressurized cabin air to enter,
forming a positive seal around the door.
Emergency Exit Hatch
The removable emergency exit door (hatch) is
located on the right side of the fuselage (Figure
1-14). The 20 by 36 inch emergency hatch
contains both an internal and an external latch
release mechanism. From inside the airplane,
the door may be secured by a “REMOVE BE-
FORE FLIGHT” flagged security pin that re-
stricts movement of the locking pins when
inserted.
From inside the aircraft, the emergency exit
door is opened by pulling the internal latch
handle, labeled “EXIT–PULL,” downwards.
This extracts the two locking pins, located at
the top of the hatch. The exit door can then be
pulled inward. The bottom edge of the emer-
gency exit door sits behind a lip that serves as
a non-retaining hinge during removal and in-
stallation of the emergency exit.
The emergency exit door may be opened from
outside the airplane, once the internal security
pin has been removed, by depressing the PUSH
panel at the top of the door. This action per-
forms the same unlatching of the locking pins
as does pulling the latch assembly handle from
inside the airplane. The door can then be
pushed inward and set aside. The hatch weighs
approximately 35 pounds.
Whenever the emergency exit locking mech-
anism has been disengaged, an amber caution
message, “EMERGENCY EXIT” is displayed
on the CAS (Figure 1-12).
