A. Operational Test of the Door Unlocking from Inside/Outside in "Armed" Position
(1) Make sure that the applicable door is closed and locked and the slide control handle is in the ARMED position (Ref. AMM TASK 52-22-00-410-001).
(2) Do this test to make sure that the locking mechanism of the applicable door operates satisfactorily.
Subtask 52-22-00-710-055-A ** ON A/C NOT FOR ALL (1) Make sure that the applicable door is closed and locked and the slide control handle is in the ARMED position (Ref. AMM TASK 52-22-00-410-001).
(2) Do this test to make sure that the locking mechanism of the applicable door operates satisfactorily.
| ACTION | RESULT |
|---|---|
| 1. Open the handle cover and pull up the inboard handle to the OPEN position. | The white SLIDE indication light comes on when the inboard handle moves up. The red UNLOCK indication comes into view on the locking indication window. The door lifts and the door release lever operates the override-clutch release lever. This causes the bellcrank lever to move rearward. |
| 2. Push the inboard handle down to the locked position and close the handle cover. | The door moves down into its locked position. The green LOCKED indication comes into view on the locking indication window. |
| | The white SLIDE indication light goes off when the inboard handle is fully moved down. |
| 3. Push the handle flap in and pull the outboard lever away from the door. | The escape slide-release mechanism moves automatically to the DISARMED mode. The door moves up and comes free from its opening. |
| 4. Push the outboard lever down until it engages in the recess of the door. | The door lowers into its opening and moves down. |
B. Operational Test of the Escape-Slide Release-Mechanism Arming/Disarming
(1) Make sure that the applicable door is closed and locked and the slide control handle is in the ARMED position (Ref. AMM TASK 52-22-00-410-001).
(2) Do this test to make sure that the escape-slide release-mechanism operates satisfactorily.
Subtask 52-22-00-720-050-A ** ON A/C NOT FOR ALL (1) Make sure that the applicable door is closed and locked and the slide control handle is in the ARMED position (Ref. AMM TASK 52-22-00-410-001).
(2) Do this test to make sure that the escape-slide release-mechanism operates satisfactorily.
| ACTION | RESULT |
|---|---|
| 1. Pull up the slide control handle to the disarmed position. | The green DISARMED indication comes into view on the indication window of the door lining. The door release lever moves down until it comes free from the slide release lever of the frame fitting. The operation lever moves down until it comes free from the release lever of the door damper. NOTE: The door release lever and the operation lever are part of the release shaft assembly. |
| 2. Push down the slide control handle to the armed position. | The red ARMED indication comes into view on the indication window of the door lining. The door release lever moves up and engages with the slide release lever of the frame fitting. The operation lever moves up and engages with the release lever of the door damper. |

Measurement of Actuation Travel ** ON A/C NOT FOR ALL
(1) Make sure that the applicable door is locked and in the ARMED mode.
(2) To decrease the play in the release lever assembly, do as follows:
(a) Install a STRAP-227 KG(500 LB),NYLON on the release lever to attach the dynamometer.
(b) Put a DYNAMOMETER 20 DAN (45 LBF) - PULL in position on the nylon strip to connect it to the release lever.
(c) Pull on the dynamometer with a force of max. 10.0 daN (22.4809 lbf) during the complete test.
(3) Do this test to make sure that:
