B. Preparation for the Test

Operation of the Emergency Exit Hatch ** ON A/C NOT FOR ALL

(1) Make sure that the hatch is correctly closed and its extended latch pin is engaged with the related release lever (Ref. AMM TASK 52-21-11-400-001).
(2) Install the lockpin assembly in the operating head of the inflation reservoir to prevent an accidental operation of the inflation reservoir (Ref. AMM TASK 25-62-00-481-001).
(3) Remove the inflation reservoir assembly from the flexible control assembly as follows:

WARNING: USE PROTECTIVE GOGGLES AND GLOVES WHEN YOU REMOVE OR INSTALL LOCKWIRE. EACH TIME YOU CUT LOCKWIRE, REMOVE AND DISCARD IT IMMEDIATELY. LOOSE LOCKWIRE CAN CUT YOU OR MAKE YOU BLIND, AND/OR CAN CAUSE DAMAGE.

CAUTION: DO NOT PUSH THE END OF THE WIRE INTO THE WIRE-CONTROL ASSEMBLY. THIS CAN CAUSE A KINK IN THE WIRE.

(a) Cut, remove and discard the lockwire from the knurled sleeve nut.
(b) Loosen the knurled sleeve nut and disassemble the two collets from the flexible control assembly.
(c) Disengage the inflation cable from the release cable.
(4) Install the TLW101 TEST TOOL-RELEASE CABLE,ESCAPE SLIDE on the flexible control assembly as follows:

CAUTION: DO NOT PUT WEIGHT ON THE FWD PULLEY WHEN YOU CONNECT THE WIRE- CONTROL ASSEMBLY TO THE FLEXIBLE CONTROL-ASSEMBLY. WEIGHT ON THE PULLEY CAUSES TENSION IN THE WIRE, WHICH CAN CAUSE THE END OF THE WIRE TO BREAK.

(a) Remove the cover cap from the test tool.
(b) Engage the adapter with the release cable and put the collets in position around the joint.
(c) Turn the knurled sleeve nut to safety the connection of the test tool and the flexible control assembly.

4. Procedure
Subtask 52-21-00-710-050-A ** ON A/C NOT FOR ALL

A. Operational Test

Operation of the Emergency Exit Hatch ** ON A/C NOT FOR ALL

(1) Do this test to examine the operation of the hatch locking mechanism from the inner side.
(2) Do this test to examine the operation of the slide release mechanism from the inner side.

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 indicator-light SLIDE ARMED comes on.
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 lever in the down position.
Carefully lower the top of the hatch into the cabin, until it comes free of the cabin lining.	The extended latch pin moves the release lever of the slide release mechanism to its end position. The slide release mechanism operates the flexible control assembly. The white indicator-light SLIDE ARMED goes off.
	In the aft cargo compartment: The end of the release cable retracts and operates the spring-loaded test tool.
Remove the hatch from the opening.	The spring-loaded test tool will make the release lever automatically go back to the normal position.
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.
3.In the center of the cabin:	In the center of the cabin:
Install the hatch correctly (Ref. AMM TASK 52-21-11-400-001).	The opening of the emergency exit is closed.
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 indication-light SLIDE ARMED comes on.
Install the cover flap on the hatch lining and push it against the hatch.	The white indicator-light SLIDE ARMED goes off.
Examine the position of the hatch seal.	Make sure that the position of the hatch seal is correct.
