General

This TASK gives the procedure for the inspection of the bleed air ducts remaining 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 TASK numbers of the practices and processes referred to in the procedure are in the SPM.

The policy which is necessary for inspection is given in the SPM TASK 70-20-01-200-501.

All parts must be cleaned before they are examined, refer to Cleaning-000 TASK 36-11-49-100-100.

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. The limits for cracks are given in the SUBTASK for each part.

Do not discard any part until you are sure that 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.
