EMERGENCY EXIT HATCH OPERATION (FROM OUTSIDE)
Figure 1-12
A52-1039
Pilot’s Manual
1-20 PM-126A
Installing the right aft emergency exit hatch from the inside:
The emergency exit hatch is designed to be installed
from inside the cabin only. Ensure the seat next to the
emergency exit hatch is positioned in the fully
inboard position before installing the hatch.
1. Position the emergency exit hatch next to the emergency exit
opening on the inside of the cabin.
2. Tilt the upper end of the emergency exit hatch down and
inward (several inches).
3. Position the lower edge of the hatch so that the fittings on the
lower edge of the hatch align with and engage the fittings on
the lower side of the emergency exit opening.
4. Set the hatch in place on the lower fittings and grasp the
emergency exit handle and pull it fully inward and down. This
will retract the latch pins into the top of the hatch.
5. While keeping the latch pins retracted push the upper edge of
the emergency exit hatch into the cabin structure (hatch frame).
Ensure the emergency exit hatch seal fits into the hatch frame
evenly and does not become caught or bound.
6. Release the emergency exit handle and ensure the latch pins
extend into the cabin structure. The handle is spring loaded and
should fully retract when released.
7. Attach the handle cover to the inner panel with the hook and
loop fasteners.
RIGHT AFT EMERGENCY EXIT ANNUNCIATIONS
A hatch warning system microswitch is installed on one of the latch
pins above the right aft emergency exit hatch frame. If this microswitch
senses that the latch pin is not in the fully extended position, the switch
will cause an amber caution EMERGENCY EXIT message to be
displayed on the EICAS.

EXTERNAL DOORS
BAGGAGE COMPARTMENT DOOR
The baggage compartment door provides access to the baggage
compartment and is located on the left side of the fuselage below the
left engine nacelle. The door is 33 inches (84 centimeters) wide and is
hinged on the forward side. The baggage door has two latches and an
optional security lock installed on the aft side. The door is equipped
with a strut and opens to the forward side for unobstructed loading.
TAILCONE ACCESS DOOR
The tailcone access door is located on the lower side of the fuselage aft
of the right engine and provides access to the aft equipment bay. The aft
equipment bay contains many of the electrical, environmental,
hydraulic and engine fire extinguishing system components. The door
is hinged at the lower edge and is secured at the upper side with two
latches. It opens downward for access to the listed components.
EXTERNAL DOORS ANNUNCIATIONS
Illumination of the EXTERNAL DOORS amber CAS message indicates
that either the baggage compartment door or the tailcone access door
switches have not signaled that the door is closed. There are two
switches on each door. The switches are designed to indicate a door
open condition if it exists, prior to takeoff. If the doors were properly
latched prior to takeoff and the light illuminates in flight, the most
probable cause is a switch failure.
EXTERNAL SERVICE DOORS
OXYGEN SERVICE DOOR
The nose oxygen servicing door is located on the lower right side of the
nose, below the right side nose avionics access panel. The nose access
door is hinged at the lower edge and is secured at the upper edge with
two latches.
On aircraft modified by SB 45-12-1 (Installation of Remote Oxygen Servicing
Provisions), an optional remote mounted oxygen filler port and electrically-
driven oxygen temperature/pressure gauge are installed behind
this service door.
If applicable, an oxygen servicing door located on the right wing root
may also be installed. An oxygen filler port and electrically-driven oxygen
temperature/pressure gauge are installed behind this service
door. The door is hinged on the forward edge and latched at the trailing
edge with two latches.
