General
Refer to Inspection-000 TASK 75-32-52-200-400 (75-32-52, Inspection-000, Page 801) for other related parts.
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 70-20-01-220-501.
All the parts must be visually examined for damage, corrosion and wear. Defects that are not identified in the procedure must be referred to International Aero Engines AG.
Do not discard a 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 must be discarded can be held although no repair is available.
The repair of a discarded part could be shown to be necessary at a subsequent date.
