B. Preparation for the Test
   (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 52-21-00-710-051-A ** ON A/C NOT FOR ALL
A. Operational Test from the Outer side
   (1) Do this test to examine the operation of the hatch locking mechanism and the slide release mechanism from the outer side.
ACTION
RESULT
1.On the wing, push the flush panel:
In the center of the cabin:
WARNING: BE CAREFUL WHEN THE HATCH COMES FREE OF THE CABIN LINING. THE MOVEMENT OF THE RELEASE MECHANISM CAN CAUSE YOU INJURY.
  • 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 extended latch pin operates the release lever of the slide release mechanism.
2.In the aft cargo compartment:
In the aft cargo compartment:
  • Make sure that the end of the release cable is retracted.
  • The pointer of the test tool must get into the green area.
3.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.
4.In the center of the cabin:
In the center of the cabin:
  • The opening of the emergency exit is closed.
  • Push the latch pin against the spring and turn its head a quarter turn clockwise.

Subtask 52-21-00-860-052-A ** ON A/C NOT FOR ALL
A. Put the aircraft back to the serviceable condition.
   (1) Remove the TLW101 TEST TOOL-RELEASE CABLE,ESCAPE SLIDE from the flexible control assembly as follows:
CAUTION: DO NOT PUSH THE END OF THE WIRE INTO THE WIRE-CONTROL ASSEMBLY. THIS CAN CAUSE A KINK IN THE WIRE.
     (a) Loosen the knurled sleeve nut and disassemble the two collets from the flexible control assembly.
     (b) Disengage the adapter from the release cable.
   (2) Connect the flexible control assembly with the inflation reservoir 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) Engage the inflation cable with the release cable.
     (b) Put the collets in position and tighten the knurled sleeve nut.
NOTE: When you install the collets, one of the slots must point to you. Through the slot, you can do a visual check that the wire stays connected, while you tighten the sleeve nut.
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.
     (c) Safety the knurled sleeve nut with the 14QFB1Wire-Locking Dia: 0.8 mm CRES Nickel Alloy -.
