TASK 75-24-48-200-401 Examine The Turbine Case Cooling (TCC) Manifold Bracket, Inspection-001
General
This TASK gives the procedure for the inspection of the TCC manifold bracket. For the other HP ACC manifold parts, refer to Inspection-000 TASK 75-24-48-200-400.
Fig/item numbers in parentheses 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.
The policy that is necessary for inspection is given in SPM TASK 70-20-01-200-501.
All the parts must be cleaned before any part is examined. Refer to Cleaning-000 TASK 75-24-48-100-400.
All parts must be visually examined for damage, corrosion and wear. Any defects that are not identified in the procedure must be referred to IAE.
The procedure for those parts which must have a crack test is given in Step Do the test before the part is visually examined. Limits for cracks are given in the SUBTASK for each part.
Do not discard any part until you are sure there are no repairs available. Refer to the instructions in Repair before a discarded part is used again or oversize parts are installed.
Parts which should be discarded can be held although no repair is available. The repair of a discarded part could be shown to be necessary at a later date.
