Subtask 52-21-00-710-052-A ** ON A/C NOT FOR ALL

A. Operational Test
(1) Do a check of the passenger-door flexible arm/disarm control-cable.
(a) Make sure that the passenger-door flexible arm/disarm control-cable is in a serviceable condition.
(2) Do the test that follows to examine the operation of the hatch locking mechanism from the inner and outer side.
(3) Do the test that follows to examine the operation of the latch pin from the armed to the disarmed mode.

ACTION	RESULT
1.In the center of the cabin:	In the center of the cabin:
Pull down and remove the cover flap from the hatch.	The white SLIDE ARMED indicator-light comes on.
2.On the hatch structure:	On the hatch structure:
Push the latch pin against the spring and turn its head a quarter turn counterclockwise.	The latch pin retracts to the DISARMED position. In the center of the cabin: The retracted latch pin does not operate the adjacent pin of the proximity switch. The white SLIDE ARMED indicator-light goes off.
3.In the center of the cabin:
Pull the pull-lever of the hatch control handle down and hold the hatch in position.	The hooks of the locking mechanism disengage from the upper roller fittings. The linkage of the hatch control handle locks the pull lever in this lowered position.
Carefully lower the top of the hatch into the cabin and remove the hatch.	The opening of the emergency exit is free.
Put the hatch correctly in open position and lift the pull lever in its overcenter position.	The opening of the emergency exit is closed and the hatch is correctly locked.
WARNING: BE CAREFUL WHEN THE HATCH COMES FREE OF THE CABIN LINING. THE MOVEMENT OF THE RELEASE MECHANISM CAN CAUSE YOU INJURY. 4.On the wing, push the flush panel:	In the center of the cabin:
Push the flush panel of the hatch control handle inboard.	The pull-handle of the hatch control handle moves down and operates the hooks of the locking mechanism.
	The hatch comes inboard and its retracted latch pin does not operate the release lever of the slide release mechanism.
5.In the center of the cabin:	In the center of the cabin:
Put the hatch correctly in open position and lift the pull lever in its overcenter position.	The opening of the emergency exit is closed and the hatch is correctly locked.
Push the latch pin against the spring and turn its head a quarter turn clockwise.	The latch pin extends in its ARMED position and operates the pin of the related proximity switch. The white SLIDE ARMED indicator-light comes on.
Install the cover flap on the hatch lining and push it against the hatch.	The white SLIDE ARMED indicator-light goes off.
Examine the position of the hatch seal.	Make sure that the position of the hatch seal is correct.
