1. INTRODUCTION
The aircraft has 12 doors consisting of the passenger door, the galley service door, four
overwing emergency exits, the cockpit overhead escape hatch, three cargo doors, the
avionics compartment door and the aft equipment compartment door. The passenger and
flight compartment doors can be operated from inside or outside of the aircraft and can also
be used for emergency evacuation. The three cargo doors, the aft equipment compartment
door and the avionics compartment door can only be operated from outside the aircraft. All
doors, except the aft equipment compartment door and the cockpit overhead escape hatch
are monitored by the proximity sensing electronic unit which provides the flight crew with
door status information on the EICAS. <2224>

1. PASSENGER DOOR
The passenger door, located at the forward left-hand side of the fuselage, is the main
entrance and exit to the cabin area.
The passenger door incorporates integral stairs with a retractable lower step and folding
handrails. The door is hinged at the cabin floor level and opens outward. A
counter--balance mechanism with gas springs is used to take the weight of the door and to
dampen the door movement At the fully open position, the door rests on a support wheel.
Handrails are provided to assist passengers in boarding and disembarking. Mechanical
linkages raise the handrails when the door is opened and collapse them when the door is
closed. When jetways are in use, the handrails must be collapsed. Collapsing of the
handrails is done by removing the forward and aft handrail quick--release pins (fig 06--20--4).
Closing the passenger door from inside the aircraft is normally accomplished using the
power assist system which is controlled from a DOOR ASSIST switchlight on the forward
fight attendants panel.
A. Opening the Door from Inside
(1) Lift the inner handle out of its cam recess.
S The outer handle ejects from its recess.
S The latch mechanism unlocks.
S The pressurization flap on the passenger door’s exterior surface opens.
(2) Continue the upward movement of the handle to the OPEN position.
S The latch cams and latch pins disengage from the door frame fittings.
S Fwd and aft pull--out levers open the door to the near vertical (balanced)
position.
(3) Firmly push the door outward.
NOTE
Maximum load capacity of the door is 454 kgs (1000
lbs) or a maximum of four passengers on the stairs at
any time.
S The door descends in a gradual downward movement (dampened by the
