TASK 72-45-23-200-001-B00 HPT Stage 1 Duct Band Segment - Examine, Inspection-001
General
This TASK gives the procedure for the inspection of the stage 1 HPT band segment assembly. For the other parts of the stage 1 HPT duct segment assembly, refer to TASK 72-45-23-200-000.
Fig/item numbers in parentheses in the procedure agree with those used in the IPC.
The policy that is necessary for inspection is given in SPM TASK 70-20-00-200-501.
All the parts must be cleaned before any part is examined. Refer to SPM TASK 70-10-00-100-501.
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.
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.
All parts must be examined to make sure that all the repairs have been completed satisfactorily.
The practices and processes referred to in the procedure by the TASK numbers are in SPM.
