Common Information

TASK 72-41-00-200-013-B00 HPC Assembly - Do An Inspection After A HPC VSV Lever Fracture Failure, Inspection-002

General

This TASK gives the inspection procedure, during the disassembly of the HP compressor, following a HPC VSV Lever Fracture Failure.

All Fig/item numbers in the procedure agree with those used in the IPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the IPC.

For all parts identified in a different Chapter/Section/Subject, the applicable Chapter/Section/Subject comes before the Fig/item number.

Procedure

    1. SUBTASK 72-41-00-220-185 Examine the HPC VSV Lever Fracture Engines

    1. Refer to: Figure

      2. Where engines have sustained HPC VSV lever fractures, the HPC rotor blades must be rejected as follows:

        1. VIGV lever fracture.

        1. Replace all stage 3 blades HPC Rotor Blades (72-41-15, 01-200).

        2. Stage 3 lever fracture.

        1. Replace all stage 3 and 4 blades HPC Rotor Blades (72-41-15, 01-200 , HPC Rotor Blades01-500).

        3. Stage 4 lever fracture.

        1. Replace all stage 4 and 5 blades HPC Rotor Blades (72-41-15, 01-500 , HPC Rotor Blades01-800).

        4. Stage 5 lever fracture.

        1. Replace all stage 5 and 6 blades HPC Rotor Blades (72-41-15, 01-800 and HPC Rotor Blades72-41-15, 02-170, HPC Rotor Blades02-185, HPC Rotor Blades02-200, HPC Rotor Blades02-215, HPC Rotor Blades02-217).
