Installation of the Power Plant with Cobra Tool [CFMB]

TASK 71-00-00-400-042-A-02
Installation of the Power Plant with Cobra Tool

WARNING: MAKE SURE THAT YOU HAVE THE CORRECT FIRE FIGHTING EQUIPMENT AVAILABLE.
WARNING: MAKE SURE THAT THE GROUND SAFETY-LOCKS ARE IN POSITION ON THE LANDING GEAR. THIS WILL PREVENT UNWANTED MOVEMENT OF THE LANDING GEAR, AND THUS POSSIBLE INJURY TO PERSONS AND DAMAGE TO THE AIRCRAFT AND/OR EQUIPMENT.
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 ALL THE CIRCUITS IN MAINTENANCE ARE ISOLATED BEFORE YOU SUPPLY ELECTRICAL POWER TO THE AIRCRAFT. UNWANTED ELECTRICAL POWER CAN BE DANGEROUS.
CAUTION: DO A CHECK OF THE ENGINE DATA PLATE TO MAKE SURE THAT THE ENGINE IS CORRECT FOR THE AIRCRAFT. IF YOU INSTALL AN ENGINE THAT DOES NOT HAVE THE CORRECT CONFIGURATION FOR THE AIRCRAFT:
  • DAMAGE TO EQUIPMENT CAN OCCUR IF YOU OPERATE THE ENGINE.
  • THE TEST AFTER THE INSTALLATION WILL TELL YOU THAT THE ENGINE CONFIGURATION IS NOT CORRECT AND MORE WORK WILL BE NECESSARY.

1. Reason for the Job
NOTE: The engine thrust rating must be the same as on opposite engine and consistent with the aircraft model.
NOTE: Interferences between the LPTACC inlet airscoop assy and the thrust reverser cowl have been observed in production on a limited number of A320 Family aircraft powered with CFM56-5B/3 engines. CFM has issued SB CFM56-5B S/B 75-0044. In order to recover the gap between the LPTACC scoop and the thrust reverser cowl to avoid potential interference, Airbus recommends to incorporate this SB at the opportunity of engine removal/installation.
