MAINTENANCE MANUAL
(3)
The door is closed from inside the airplane by releasing hold-open latch securing the door in the stowed position and manually sliding the door forward along the carriage tracks until it contacts the forward door snubbers which releases the carriage latch. The door handle is then pulled out and rotated counterclockwise one-half turn. Initial rotation of the handle causes the control cam to operate the upper and lower hinge fitting linkages which moves the door outboard to the door closed position. The door is guided into the opening by the station programming cam and follower located at the lower forward portion of the door. Final rotation of the handle operates the door latching mechanism and returns the door handles to the flush position.
