travel). When the door is locked, a green flag indicator will show through the window in the handle.
NOTE: In order to prevent a cabin pressure bump during door closure, it is recommended that the air
conditioning supply be selected OFF prior to the door being closed. Following door closure, the air conditioning
supply can be reselected.
MANUAL OPERATION
In the event of loss of power to the actuator, the passenger door can be closed manually.
To close the passenger door manually from outside the aircraft, lift the door upward to the closed position. To engage the
door locks, push the outer door handle into the recess in the door.
To close and lock the passenger door from inside the aircraft, raise the hinged cover located on top of the actuator housing
and pull up on the T-handle. Pulling on the cable handle a number of times wraps the door lifting cable into the actuator
housing and raise the passenger door into the closed position. To lock the door, rotate the inside handle downward until it
stops. When the door is closed, a green flag indicator shows through the window in the handle.

DOOR LATCHING MECHANISM
The door latch mechanism consists of two cams which are part of a primary shaft installed horizontally on the door structure.
The primary shaft turns with inputs from the internal handle and the external handle. The internal handle
attaches directly to the primary shaft. The external handle connects to the primary shaft through control rods and a lever.
The latch mechanism has three different primary functions as follows:.
- Vent flap function
- Door lifting function
- Open lock function
VENT FLAP FUNCTION
It is not possible to open the cabin door if some cabin pressure remains. A pressure lock lever, which connects to the vent
flap through a control rod and link, prevents movement of the inner handle and the vent flap stays closed. After cabin pressure
is released, the springs allow the vent flap to open. The pressure lock disengages, and the door handles can then operate.
The springs also insure that the vent flap opens if a part of the operating mechanism becomes unserviceable or
disconnects. If one spring breaks, the other two springs can open the vent flap to release cabin pressure.
DOOR LIFTING FUNCTION
Another cam on the primary shaft of the latch mechanism causes the door to move vertically. As the cam turns, force is
applied to a lever which connect to a lifting shaft installed parallel to the primary shaft. At each end of the lifting shaft is a
lever which connects to the door hinge mechanism. Movement of the two levers causes the door to move vertically in relation
to the hinge.
The lifting shaft has a locking ratchet cam connected to the vent flap cam which stops vertical movement of the door unless
the vent flap is fully open. A pressure lock system also stops more movement of the primary cam shaft if the vent flap is
kept closed by too much cabin pressure. When the pressure decreases sufficiently, the springs can open the vent flap and
the locking cam moves to let the lifting shaft turn.
OPEN-LOCK FUNCTION
When the door is fully open it is not possible to close it until a system of mechanical locks is released. This lock mechanism
also prevents too much vertical movement of the steps when entering and exiting the aircraft.
When the door is fully open, the primary lock engages the locking cam on the external handle pivot shaft.
PASSENGER DOOR ANNUNCIATIONS

conditions exist:
- The aircraft is on the ground with the left engine run switch in the OFF position
