3. Job Set-up
Subtask 25-62-00-860-058-A ** ON A/C NOT FOR ALL

A. Aircraft Maintenance Configuration

NOTE: Airbus recommends you to do the operational test in the maintenance hangar.

NOTE: You can do the maintenance deployment procedure in the maintenance hangar if there are bad environmental conditions (wind, rain, haul or very high temperature).

(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) Do the operational test of the emergency light with the Multipurpose Control & Display Unit (MCDU) or the TEST EMER LIGHT SYS pushbutton on the Programming and Test Panel (PTP) (Ref. AMM TASK 33-51-00-710-001).

Subtask 25-62-00-941-061-A ** ON A/C NOT FOR ALL

B. Safety Precautions

Escape Slide Deployment - Preparation ** ON A/C NOT FOR ALL

(1) Open the applicable emergency exit door (referred to as the door) from the inner side of the passenger compartment (Ref. AMM TASK 52-22-00-010-001).
(2) Prevent damage to the fuselage:

CAUTION: MAKE SURE THAT THE PROTECTION IS IN POSITION ON THE FUSELAGE BELOW THE DOOR SILL. DEPLOYMENT OF THE ESCAPE-SLIDE CAN CAUSE DAMAGE TO THIS AREA.

CAUTION: USE ONLY THE SPECIFIED MATERIALS AND OBEY THE INSTRUCTIONS FROM THE MATERIAL MANUFACTURERS. OTHER MATERIALS CAN CAUSE DAMAGE TO THE SURFACE PROTECTION OF THE COMPONENTS AND THE RELATED AREA.

(a) Put the ACCESS PLATFORM 5M (16 FT)- ADJUSTABLE in position below the applicable door.
(b) Put the protection material in position on the fuselage:

CAUTION: MAKE SURE THAT THE PROTECTION IS CORRECLTY ATTACHED WITH TAPE TO THE AIRCRAFT STRUCTURE. THIS PREVENTS THE SUCTION OF LOOSE MATERIAL INTO THE ASPIRATOR DURING DEPLOYMENT. LOOSE MATERIAL CAN CAUSE DAMAGE TO THE ASPIRATOR.

Escape Slide Deployment - Preparation ** ON A/C NOT FOR ALL

2 Use adhesive tape Sealing Profile-Vaccum Bag Sealant - - (Material No.14JEA1) and attach the Laminate Repair Patch-Fire compliant - Cargo (Material No.13XCA4) to the surface of the fuselage below the door sill.

NOTE: The protection material is a lamination of fiberglass reinforced polyester (or equivalent material) which has a minimum thickness of 1.2 mm (0.05 in.). It is thin and resistant to impact. It applies the load equally to prevent damage to the fuselage.

NOTE: You cannot use the bubble wrap as a protection material for the fuselage.

(3) Do the ground safety procedure:

WARNING: PUT SAFETY BARRIERS IN POSITION TO KEEP THE TRAVEL RANGE OF THE ESCAPE-SLIDE CLEAR. IF YOU DO NOT, INJURY TO PERSONNEL AND/OR DAMAGE TO EQUIPMENT CAN OCCUR.

(a) Make sure that an area with a radius of approximately 12.0 m (39.3708 ft.) below the applicable emergency exit door is clear of all the equipment.
(b) As necessary, use the applicable SAFETY BARRIERS, specified by the operator's instructions and your local regulations.
(c) Put the SHEET - PLASTIC in position where the escape slide hits the ground.
(d) Put the WARNING NOTICE(S) in position to tell persons not to go in the area behind the safety barrier(s).
(4) Push the release button (3) and pull the door with the assist handle (6) to get access to the door damper and the emergency operation cylinder.
(5) Record the pressure value shown on the pressure gage of the door damper and the emergency operation cylinder to make sure that the pressure value is correct. Refer to the values given in the pressurization of the pressure accumulator (Ref. AMM TASK 52-22-00-614-002).
(6) Make sure that the door damper and the emergency operation cylinder are in armed position (Ref. AMM TASK 52-22-00-860-004).
(7) Close the applicable emergency exit door from the inner side of the passenger compartment (Ref. AMM TASK 52-22-00-410-001):
(a) Do a visual check of the pressure gage (14) of the inflation reservoir (12) with the applicable procedure:

Open the Overhead Stowage Compartment (OHSC) door (9) to get access to the inflation reservoir inspection-window (10) or
Push the quick-release fasteners (13) and open the access panel (11).

NOTE: You can see the pressure gage (14) through the inflation reservoir inspection-window (10) or through the opened access panel (11).

(b) Make sure that the pressure gage (14) shows the correct pressure value.
(c) Close the OHSC door (9).
(8) In the cockpit, on the overhead panel, on the SIGNS section of panel 25VU, make sure that the EMER EXIT LT switch (1) is set to ARM.

Subtask 25-62-00-710-050-A ** ON A/C NOT FOR ALL

A. Operational Test of the Escape slide Deployment

Escape Slide Deployment - Preparation ** ON A/C NOT FOR ALL

(1) Prepare the VIDEO CAMERA(s):

NOTE: Airbus recommends to use three VIDEO CAMERA(s) and the STOPWATCH to record and measure the time of the deployment sequence. The operator's local authority can make it mandatory to use the VIDEO CAMERA(s) to record the deployment sequence.

(a) Put the VIDEO CAMERA(s) in these positions:
1 Two VIDEO CAMERA(s) on the outside of the aircraft, behind the safety barrier(s):

One opposite the door
One parallel to the fuselage that points in the direction of the door.

2 One VIDEO CAMERA in the aircraft opposite the door.

NOTE: If only one VIDEO CAMERA is available, then put it on the outside of the aircraft, opposite to the door, behind the safety barrier(s).

(b) Set the focus of the VIDEO CAMERA(s) to the manual mode.
(c) Make sure that the VIDEO CAMERA(s) is (are) zoomed out.
(2) Start the VIDEO CAMERA(s).
(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.

NOTE: In usual test conditions (hangar) 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.

WARNING: IF THE ESCAPE SLIDE DOES NOT INFLATE AUTOMATICALLY, MAKE SURE THAT:

NO PERSONS OR EQUIPMENT ARE IN THE SLIDE DEPLOYMENT AREA, AND
THE DOOR IS IN ITS FULLY OPEN AND LOCKED POSITION, AND
THE SLIDE IS FULLY RELEASED OUTSIDE THE CABIN,

THEN PULL THE MANUAL HANDLE TO INFLATE THE SLIDE.

(a) Hold on to the assist handle (5) on the door-frame lining.
(b) Lift the door control-handle (4) 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) Put the safety barrier strap (2) in position across the exit.
(6) Stop the video cameras. If necessary, use the video tapes to make an analysis of the deployment sequence.
(7) 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.

(a) Push the release button (3) and pull the door with the assist handle (6) until it is in the correct position.
(b) Carefully lower and lock the door with the door control-handle (4).
(c) Open the protection cover (7) and set the emergency control-handle (8) to DISARMED.
(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 (8) is set to DISARMED.

(8) Record the time of the deployment sequence. Keep this information with the deployed escape slide after it is removed for restoration.
(9) Record the deployment in the report form (Ref. AMM TASK 25-62-00-910-801).
