NOTE
The water barrier is installed at the
main cabin door threshold. Crew
members should be familiar with its
location and operation; and passen-
gers should be briefed prior to flights
over water.
A monitoring system checks for safe condition
of the door (closed, pins secure, door latched).
There are eight view ports on the inside panel
of the entry door to verify that the eight lock-
ing pins are in the closed position. With the
door closed and handle latched, the pilot
should be able to see the white and green in-
dicators in each port. (Figure 1-7). Three prox-
imity switches verify that the door is closed,
latched, and locked by sensing the position of
targets on the closing mechanism of the door
and signals the condition to the CAS:
• The proximity switch on the doorway
surround structure senses the door after
it is closed.
• After the door is latched, a proximity
switch senses the door pin position.
• As the handle catch is engaged, a prox-
imity switch on the inner handle assem-
bly senses a flag.
If one of the proximity switches does not sense
its target, the CABIN DOOR message appears
on the CAS.
EMERGENCY EXIT
A plug-type emergency exit (escape hatch) is
on the aft right side of the cabin, above the
wing. It opens inboard. The emergency exit
door can be opened from outside or inside
the airplane (Figure 1-8).
The D-shaped inner door handle is recessed be-
hind a magnetic cover. The flush-mounted
outer handle is located at the top of the door.
The outer handle is not directly connected to
the inner handle. The outer handle has a green
indicator to show when the door is latched.
Because no other provisions are provided for
securing the escape hatch when the airplane
is unattended, a safety pin with a REMOVE
BEFORE FLIGHT streamer is placed on the
inside of the hatch. The pilot must ensure this
pin is removed prior to flight. The emergency
exit hatch is not connected to the door warn-
ing circuit.
CABIN
The cabin extends from the forward pressure
bulkhead to the aft pressure bulkhead and
