Purpose
The handle mechanism holds the door closed when the
airplane is not pressurized and opens the door when
necessary.
General Description
The handle mechanism consist of these components:
* Pressure vent panel
* A handle
* Locking mechanism.
Pressure Vent Panel/Handle
The pressure vent panel and the handle are combined. They
turn at the same time around the same torque tube to open the
emergency exit door.
When the cabin is pressurized, the pressure vent panel initially
resists the operation of the handle. Cabin pressure must vent
through the pressure vent panel before you can open the door.
The pressure vent panel and handle are spring-loaded to the
close position.
The handle lets the operator open the door. When you pull the
handle, the torque tube pulls the lock rollers out of the lock
receiver. This causes the door to move inboard and down. This
inboard and downward movement lets the door clear the stop
fittings and open.

Purpose
The hinge arm lock pawl mechanism latches the door in the
open position.
Location
One lock pawl mechanism is on each side of the emergency exit
door frame.
General Description
The hinge arm lock pawl mechanism has these components.
* Lock crank
* Lock pawl
* Lock pawl depressor
* Torsion spring.
The lock crank and the lock pawl work together to stabilize the
door when it is open.
The lock pawl depressor prevents the lock pawl from
engagement of the hinge arm before the door is fully open.
This lets the hinge arm and door move freely between the latch
and unlatch positions.
The torsion spring pushes the lock pawl to the lock position.
