WARNING: MAKE SURE THAT THE LOCK PIN IS CORRECTLY INSTALLED IN THE REGULATOR VALVE ASSEMBLY OF THE INFLATION RESERVOIR. THIS SAFETIES ALL COMPONENTS OF THE INFLATION SYSTEM IN OPERATION AND PREVENTS ACCIDENTAL:
  • DISCHARGE OF THE INFLATION RESERVOIR
  • DEPLOYMENT OF THE ESCAPE SLIDE
WHICH CAN CAUSE INJURY AND/OR DAMAGE.
A. Safety Precautions
NOTE: We recommended that only personnel who know the system do this procedure.
   (1) Fuselage protection procedure:
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.
     (a) Do not use bubble wrap as protection for the aircraft fuselage.
NOTE: The protection is a lamination of fiberglass-reinforced polyester which has a minimum thickness of 1.2 mm (0.05 in.). It is thin, resistant to impact and applies the load equally to prevent damage to the fuselage.
     (b) Put an ACCESS PLATFORM 5M (16 FT)- ADJUSTABLE in position to help you attach the protection.
     (c) Attach the protection in position:
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.
     (d) Refer to the FIGURE for the dimensions and position of the protection.
     (e) Use Sealing Profile-Vaccum Bag Sealant - - (Material No.14JEA1) and attach Laminate Repair Patch-Fire compliant - Cargo (Material No.13XCA4) on to the surface of the fuselage below the door sill.
   (2) 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) Below the applicable door, make sure that an area with a radius of approximately 12.00 m (39.37 ft.) is clear of all miscellaneous equipment.
     (b) As necessary, use the applicable SAFETY BARRIERS, specified by the operator's instructions and your local regulations.
     (c) Put 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 into the area behind the safety barriers.
   (3) Cockpit safety procedure:
WARNING: PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR:
  • THE FLIGHT CONTROLS
  • THE FLIGHT CONTROL SURFACES
  • THE LANDING GEAR AND THE RELATED DOORS
  • COMPONENTS THAT MOVE.
MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/OR CAN CAUSE DAMAGE TO THE EQUIPMENT.
     (a) Set the slat/flap control lever to the 0 position (Ref. AMM TASK 27-50-00-866-009).
     (b) Install the 98D27803000000 LOCKING TOOL-FLAP SLAT LEVER,INT. POSITION on the slat/flap control lever when working near the slats/flaps.
     (c) Put the WARNING NOTICE(S) on the slat/flap control lever to tell persons not to operate the flaps.

A. Adjustment Procedure
   (1) Adjustment procedure of the regulator valve assembly:
   (2) If necessary, get access to the inflation reservoir:
     (a) In the cockpit, on overhead panel 25VU (SIGNS), make sure that the EMER EXIT LT switch is set to OFF.
     (b) Open the necessary emergency exit door from the passenger compartment (Ref. AMM TASK 52-22-00-010-001).
     (c) Put the WARNING NOTICE(S) in position, to tell persons not to close the door.
     (d) Put the exit safety-barrier strap in position.
     (e) Do one of the two applicable steps to get access to the inflation reservoir:
  • Push the quick-release fasteners (1) and release the cover (2).
  • Open the door of the overhead stowage compartment (5) and push the quick-release fasteners (3) to release the cover (4). Carefully remove the cover (4).
