Installation of the Power Plant [CFMB]

TASK 71-00-00-400-042-A
Installation of the Power Plant

WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
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
This task gives the information for the installation of the power plant.
The power plant can be installed in particular configuration. It is allowed to install the power plant with or without the air intake cowl installed.
NOTE: The engine thrust rating must be the same as on opposite engine and consistent with the aircraft model.
NOTE: Engine and nacelle are 2 ways interchangeable but with condition.
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.

CAUTION: DO A DETAILED VISUAL INSPECTION OF THE FORWARD AND AFT ENGINE MOUNTS AND ALL PARTS THAT ATTACH THE MOUNTS. THE PARTS MUST BE IN GOOD CONDITION. IF THE PARTS ARE NOT IN GOOD CONDITION, FAILURE OF THE MOUNTS CAN OCCUR.
   (1) Do a detailed visual inspection of the forward and aft engine mounts (Ref. AMM TASK 71-21-11-210-040) and (Ref. AMM TASK 71-22-11-210-042).
   (2) Do a detailed visual inspection of the forward central part (the snout) of the forward engine mount (Ref. AMM TASK 71-21-11-210-040).
   (3) Do a check of the cowling for correct condition.
   (4) Do a check of the electrical connectors of the aft and forward junction boxes for correct condition.
   (5) Do a check of the visible part of the pylon for correct condition.
CAUTION: YOU MUST REPLACE CONTACTS THAT SHOW WEAR AND TEAR SIGNS (HOLES, SCRATCHES, DISCOLORATION, TEARS AND PITTED MARKS).
CAUTION: YOU MUST REPLACE CONTACTS THAT SHOW WEAR AND TEAR SIGNS (HOLES, SCRATCHES, DISCOLORATION, TEARS AND PITTED MARKS).
   (6) Do a pin retention check of the sockets of the IDG connector ESPM 2048230 (CANNON), ESPM 2048240 (FRAMATONE-former SOURIAU) and FLIGHT CONNECTOR in the 400VCA connector of the generator harness.
  • Use a DYNAMOMETER 15 DAN (33 LBF) - PULL, the CANNON value is 1.2 daN (2.7 lbf) minimum, the FRAMATONE (former SOURIAU) value is 2.8 daN (6.3 lbf) for NEW sockets and 2.2 daN (4.9lbf) for OLD sockets and the FLIGHT CONNECTOR value is 3.5 daN (8 lbf), in accordance with pin/socket type used. Do not clean the contacts with abrasive material.

H. Cleaning
NOTE: If you use bolts (85) and (135), nuts (120) and (155), retainers (125) and (150), and washers (90) and (140) that were used before, do steps 3.H., 3.J. and 3.K.
If you use new bolts (85) and (135), nuts (120) and (155), retainers (125) and (150), and washers (90) and (140), or you use CMM examined bolts (85) and (135), nuts (120) and (155), retainers (125) and (150), and washers (90) and (140), you do not need to do steps 3.H., 3.J. and 3.K.
   (1) Clean the bolts (85) and (135), nuts (120) and (155), retainers (125) and (150), and washers (90) and (140) with isopropyl alcohol (Material No.CP1041) .
Subtask 71-00-00-210-063-A ** ON A/C NOT FOR ALL

J. Inspection of the bolts (85) and (135), retainers (125) and (150), and washers (90) and (140).
   (1) Do a fluorescent penetrant inspection level 3 of the mount bolts (85) and (135). No cracks are permitted. See CFMI standard Practices Manual SPM 703213 or SPM 703223.
   (2) Visually examine the retainers (125) and (150), and the washers (90) and (140) for indication of damage. If there are scratches, marks and/or other damage, reject the parts.
   (3) Do a visual inspection of the barrel nuts (155) with a MAGNIFYING GLASS POWER 10X. Carefully examine the thread root area of the last two threads. No cracks are permitted. If cracks are found, notify Rohr Inc.
