OUR REF.: AOT A330-52A3063 REV 01 - DATED 3 JAN 2001
0. REASON FOR REVISION
REVISION OF THIS AOT ADDS A REPETITIVE INSPECTION REQUIREMENT TO THE DESCRIBED ISSUE AND EXTEND THE EFFECTIVITY TO ALL A330.
THE INSPECTION INTERVAL IS GIVEN WITH THIS REVISION WAITING THE INTRODUCTION OF THE TASK INTO THE MPD.
- COMPLEMENT OF DESCRIPTION IN PARA 3.3,
- COMPLEMENT OF TEXT IN PARA 4.1.,
NOTE: THIS REVISION INTRODUCES NO ADDITIONAL WORK AS DESCRIBED IN PARA 4.2. REVISED SECTIONS OF THIS AOT ARE INDICATED BY THE **REV** MENTION.

3. REASON
3.1 FACTS
DURING AN ESCAPE SLIDE DEPLOYMENT TEST ON A FWD PAX/CREW DOOR
A COMPONENT OF THE SLIDE RELEASE MECHANISM WAS FOUND UNSERVICEABLE. THE LOCKING FUNCTION INSIDE ONE OF THE TWO SLIDERS WAS STUCK. SEE IPC 52-11-22-9, ITEM 10.
3.2 CONSEQUENCES
THE TWO SLIDERS INSTALLED ON EACH END OF THE GIRT BAR (REF.IPC 52-11-22-9, ITEM 90) ATTACH THE ESCAPE SLIDE EITHER TO THE DOOR (WHEN DISARMED) OR TO THE FUSELAGE (WHEN ARMED). DUE TO THE MISSING SPRING FUNCTION OF THE SLIDER (REF.IPC 52-11-22, ITEM
60) THE GIRT BAR WILL NOT BE CORRECTLY CONNECTED TO THE FUSELAGE. THE ESCAPE SLIDE COULD BECOME DETACHED FROM THE AIRCRAFT ONCE INFLATED.
3.3 AIM **REV**
THE AIM OF THIS AOT IS TO ENSURE A RELIABLE FUNCTION OF BOTH
SLIDERS BY REPETITIVE INSPECTIONS AND LUBRICATION ON ALL
PAX/CREW AND EMERGENCY EXIT DOORS UNTIL AN EQUIVALENT TASK IS INTRODUCED INTO THE MPD.
4. SHORT TERM ACTION
4.1 PLANNING **REV** THE INSPECTION DESCRIBED IN PARAGRAPH 4.2 HAS TO BE PERFORMED PRIOR TO 18 MONTHS FROM DELIVERY DATE AND TO BE REPEATED EVERY 18 MONTHS. FOR THE AIRCRAFT OLDER THAN 18 MONTHS, THE FIRST INSPECTION IS TO BE PERFORMED WITHIN 550 FH.
THOSE AIRCRAFT ALREADY INSPECTED AS PER THE FIRST ISSUE OF THIS AOT DATED 02-AUG-00 ARE TO BE REINSPECTED WITHIN 18 MONTHS FROM THE POST INSPECTION OR SLIDER REPLACEMENT AS PER THIS REVISION.
IN CASE A SLIDER IS FOUND WITHOUT LOCKING FUNCTION THE SLIDER HAS TO BE REPAIRED AS PER CMM (REFER TO REF.5) OR REPLACED BEFORE THE NEXT FLIGHT. OTHERWISE THE AFFECTED DOOR HAS TO BE DECLARED INOPERATIVE AS PER MMEL 52-10-01.
THE INSPECTION, INCLUDING ACCESS, IS ESTIMATED TO TAKE 0.3 MANHOURS PER DOOR. WHEN NECESSARY, THE REPLACEMENT OF THE SLIDER IS ESTIMATED TO TAKE AN ADDITIONAL 0.5 MANHOURS PER DOOR.
4.2 DESCRIPTION
- CLOSE AND LOCK THE DOOR.
- REMOVE THE DECORATIVE COVER OF THE ESCAPE SLIDE AS PER AMM 25-62-00-201.
- PUT THE SLIDE CONTROL HANDLE INTO THE ARMED POSITION (CAUTION: DO NOT OPEN THE DOOR IN THIS POSITION TO AVOID SLIDE RAFT DEPLOYMENT).
- LOOK AT EACH SIDE BELOW THE ESCAPE SLIDE PACKBOARD ASSEMBLY USING A TORCH.
- INSERT A SCREWDRIVER (LENGTH ABOUT 250 MM) WITH FLAT HEAD
BETWEEN THE HOOK AND THE GUIDE PIN WHICH MOVES THE SLIDER (REFER TO REF.2).
- CHECK THE SPRING FUNCTION OF THE LOCKING HOOK INSIDE THE SLIDER MECHANISM BY SLIGTHLY TURNING THE SCREWDRIVER.
NOTE: SHOULD THE SPRING FUNCTION NOT BE NOTICEABLE, REPLACE THE SLIDER AS PER AMM (REFER TO REF.3).
- THEN INSTALL THE DECORATIVE COVER OF THE ESCAPE SLIDE AS PER AMM 25-62-00-201.
- PUT THE SLIDE CONTROL HANDLE BACK INTO THE DISARMED POSITION.
- OPEN THE DOOR.
- APPLY CORROSION INHIBITOR (MAT. N° 05-027) TO THE SLIDERS (E.G. AS A SPRAY DEPENDING ON THE ACCESS WITH OR WITHOUT OUTSIDE PLATFORM).
- CLOSE AND LOCK THE DOOR.
4.3 MATERIAL
NO SPECIFIC TOOLING IS NECESSARY TO PERFORM THE REQUIRED ACTION.
5. FURTHER ACTION
TO PREVENT SLIDERS FROM BEING UNSERVICEABLE, THIS PERIODIC
MAINTENANCE TASK REQUESTING REPETITIVE INSPECTION AND
LUBRICATION WILL BE INTRODUCED INTO THE MPD WITH THE NEXT REVISION SCHEDULED BY SEP-2001.
