WARNING: MAKE SURE THAT THE SAFETY DEVICES AND THE WARNING NOTICES ARE IN POSITION BEFORE YOU START A TASK ON OR NEAR:
  • THE FLIGHT CONTROLS
  • THE FLIGHT CONTROL SURFACES
  • THE LANDING GEAR AND RELATED DOORS
  • COMPONENTS THAT MOVE.
MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.
WARNING: WEAR GLASSES AND PROTECTIVE CLOTHING WHEN YOU DO WORK ON THE LIGHT. THE LAMP IS PRESSURIZED AND AN EXPLOSION CAN OCCUR.
WARNING: MAKE SURE THAT THERE ARE NO SIGNS OF FUEL CONTAMINATION IN THE LANDING LIGHT ASSEMBLY. IF YOU FIND FUEL CONTAMINATION, NO PERSON MUST OPERATE THE LANDING LIGHT UNTIL:
  • YOU REPAIR THE FUEL LEAK
  • YOU REPLACE THE LANDING LIGHT ASSEMBLY.
IF YOU DO NOT OBEY THIS PRECAUTION, IGNITION OF THE REMAINING FUEL IN THE LANDING LIGHT CAN OCCUR.
WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
CAUTION: WHEN YOU REPLACE A LANDING LIGHT LAMP, EXAMINE THE APPLICABLE LANDING LIGHT ASSEMBLY FOR SIGNS OF FUEL CONTAMINATION. IF YOU FIND FUEL CONTAMINATION, EXAMINE THE ITEMS THAT FOLLOW FOR SIGNS OF FUEL LEAKAGE:
  • THE FUEL PUMP(S) 21QA(26QA) OR 25QA(22QA)
  • THE WATER DRAIN VALVE 25QM(26QM) DIRECTLY FORWARD OF THE LANDING LIGHT ASSEMBLY.
REFER TO AMM 28-11-00-06 FOR LEAKAGE LIMITS AND REPAIR AS NECESSARY. IF YOU DO NOT REPAIR THE LEAK, NO PERSONS MUST OPERATE THE APPLICABLE LANDING LIGHT UNTIL:
  • THE LEAK IS REPAIRED
  • THE LANDING LIGHT ASSEMBLY IS REPLACED.

WARNING: WEAR GLASSES AND PROTECTIVE CLOTHING WHEN YOU DO WORK ON THE LIGHT. THE LAMP IS PRESSURIZED AND AN EXPLOSION CAN OCCUR.
CAUTION: DO NOT TOUCH THE LAMP GLASS WITH YOUR FINGERS. THE OILS FROM YOUR SKIN WILL QUICKLY CAUSE DETERIORATION OF THE LAMP. IF YOU ACCIDENTALLY TOUCH THE LAMP GLASS, CLEAN IT WITH A LINT- FREE CLOTH. IF NECESSARY, MAKE THE CLOTH MOIST WITH WATER. DRY WITH LOW-PRESSURE COMPRESSED AIR JET. DO NOT USE ALCOHOL.
   (1) For the GE sealed-beam landing-light lamp, do these steps:
     (a) If necessary, install the new AIPC 33-42-11-01-040 SEAL (4) on the lamp housing (1).
     (b) Connect the two electrical terminals (3) to the GE sealed-beam landing-light lamp (7) with the screws (2).
     (c) Tighten the screws (2).
     (d) Install the GE sealed-beam landing-light lamp (7) in the lamp housing (1).
     (e) Make sure that the filament of the lamp is in the horizontal position (as shown on the filament position plate (8)).
     (f) Put the clamp (6) in position.
     (g) If necessary, install the new AIPC 33-42-11-01-020 CLAMP (6) with the screw (5).
