(a)
 Make sure that the pressure gage shows the correct pressure. Refer to the values given in the pressurization of the pressure accumulator (Ref. TASK 52-22-00-614-002).

 (b)
 Make sure that the door-damper and emergency-operation cylinder is armed (Ref. TASK 52-22-00-860-004).

 (6)
 Close the door from the passenger compartment (Ref. TASK 52-22-00-410-001).

 (a) Do a visual check of the pressure gage (10) of the inflation reservoir (9) with the applicable procedure:
 -Open the door of the overhead stowage-compartment.
 -Or, push the quick-release fasteners (8) and open the access panel (7).
 NOTE : You can see the pressure gage (10) through the inspection
____ window (6) or through the opened access panel (7).
 (b) Make sure that the pressure gage (10) shows the correct pressure.
 (7) In the cockpit, on the overhead panel 25VU (SIGNS), make sure that the EMER EXIT LT switch (1) is set to the OFF position.

_________
 Subtask 25-62-00-710-050
 A. Operational Test of the Escape-slide Deployment
 (Ref. Fig. 504/TASK 25-62-00-991-011)

 NOTE : We recommend that you use 2 video cameras (optional) and a
____ STOPWATCH to record and measure the time of the deployment sequence. The operator's local authority can make it mandatory to use video cameras to record the deployment sequence.
 (1)
 Put the video cameras in position behind the safety barriers; one opposite the door and one parallel to the door.

 (2)
 Start the video cameras to record the deployment sequence.

 NOTE : You must not use the auto-focus function.

 CES  (3) Measure the time of the deployment sequence as follows:

 (a)
 Start the stopwatch as the door starts to move up in the door cut-out.

 (b)
 Stop the stopwatch when the escape-slide is fully extended and hangs below the horizontal position. The escape-slide then continues to lower to the ground.

 NOTE : In usual test conditions (hanger) the complete sequence
____ must not be more than 10 seconds. This complies with JAA
 25.809 (f) (1) (ii).
 (4) Open the door:
 WARNING : BE CAREFUL WHEN YOU SET THE DOOR CONTROL HANDLE TO "OPEN".
_______ THE DOOR OPENS WITH SUDDEN FORCE. YOU MUST RELEASE THE DOOR CONTROL HANDLE TO PREVENT INJURY.
 (a)
 Hold on to the assist handle (3) on the door-frame lining.

 (b)
 Lift the door control-handle (2) and quickly release it.

 NOTE : The door opens automatically and locks in the open
____
 position. At the same time:

 -
The deployment (release, unfold and inflation) sequence starts.

 -
The light harness on the escape-slide comes on

 automatically. The door actuator has a hydraulic device which can cause a small pause in the door opening sequence. This makes sure that the escape-slide is deployed before the door is locked in the open position.
 (5)
 Stop the video cameras. If necessary, use the video tapes to make an analysis of the deployment sequence.

 (6)
 Stop the power supply to the light harness:

 NOTE : This is to prevent unwanted discharge of the battery, which is
____
 installed on the emergency power supply unit (EPSU).

 (a)
 Push the release rod (5), and pull the door with the assist handle (4) until it is in the correct position.

 (b)
 Carefully lower, and lock the door with the door control-handle (2).

 (c)
 Open the protection cover (12) and set the emergency control-handle (11) to the DISARMED position.

 (d)
 The light harness on the escape-slide goes off. NOTE : If you open the door again, the light harness stays off,

____ because the emergency control-handle (11) is set in the DISARMED position.
 (7) Record the time of the deployment sequence. Keep this information with the deployed escape-slide after it is removed for restoration.
 5. Close-up
________ Subtask 25-62-00-860-059
 A. Aircraft Maintenance Configuration
 (1)
 Remove the deployed escape-slide from the door (Ref. TASK 25-62-47-000-002).

 (2)
 Remove the discharged inflation reservoir (Ref. TASK 25-62-49-000-001).

 (3)
 Replace the diaphragm in the percussion mechanism of the door-damper and emergency-operation cylinder (Ref. TASK 52-22-00-860-002).
