Replacement of the Glass Assembly of the LED Landing Light

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.
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: WEAR GLASSES AND PROTECTIVE CLOTHING WHEN YOU DO WORK ON THE LIGHT. THE LAMP IS PRESSURIZED AND AN EXPLOSION 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.
