A. Job Set-up
(1) Make sure that the access platform is in position below the applicable emergency exit door.
(2) Partly open the applicable emergency exit door as required (Ref. AMM TASK 52-22-00-010-001).
(3) Do the special precautions befor maintenance on the door damper and emergency operation cylinder (referred to as door damper) (Ref. AMM TASK 52-22-00-860-003).
B. Make sure that this(these) circuit breaker(s) is(are) closed:

C. Leak Test of the Door Damper
(Ref. Fig. 201/TASK 52-22-00-991-001)
(1) Charge the pressure accumulator of the door damper with the correct pressure (Ref. AMM TASK 52-22-00-614-002).
(2) Apply a solution of OXYGEN LEAK DETECTION or a Soapy Water to the subsequent components to find an air leak:
- between the striker housing and the housing assy (leak point 1) - on the charging valve (leak point 2)
- between the pressure gauge and the bottle assembly (leak point 3) - on the vent hole of the bottle assembly (leak point 5)
- between the charging valve and the bottle assembly (leak point 6)
4. Fault Isolation

WARNING : BEFORE YOU START WORK ON THE DOOR MAKE SURE THAT: - THE SLIDE
_______ CONTROL HANDLE IS IN THE DISARMED POSITION WITH THE SAFETY PIN INSTALLED. - THE PERCUSSION LEVER OF THE DOOR DAMPER CYLINDER IS IN THE DISARMED POSITION WITH THE SAFETY PIN INSTALLED.

May 01/04 CES A. If you find a sign of nitrogen leaks (bubbles) continues as folows:
(1) If you find a leak on leak point 3:
- to 3.0 m.daN (22.12 lbf.ft) the pressure filling valve.
(a) If there still bubbles again:
- replace the seal of the pressure filling valve (Ref. AMM TASK 52-22-00-860-005) and repeat the leak test.
(2) If you find a leak on leak point 2:
- to 1.0 m.daN (88.49 lbf.in) the charching valve nut.
(a) If there still bubbles:
- replace the pressure filling valve (Ref. AMM TASK 52-22-00-860-005) and repeat the leak test.
(3) If you find a leak on leak point 4:
- replace the door damper (Ref. AMM TASK 52-22-14-000-001) and (Ref. AMM TASK 52-22-14-400-001). 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 舱门 DOORS(90)
