General

This TASK gives the procedure for the inspection of the fuel system air tubes bracket. For the other fuel system air tubes and parts, refer to Inspection-000 TASK 73-22-49-200-400 and the Component Maintenance Manual - Tubes, Ducts and Hoses (CMM-THDV2500- 1IA) Inspection-000 TASK 73-22-49-200-100.

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 the SPM TASK 70-20-01-200-501.

All the parts must be cleaned before they are examined. Refer to TASK 73-22-49-100-400.

All the 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 the relevant SUBTASK. Do the crack test before the part is visually examined.

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.

All parts must be examined to make sure that all the repairs are completed satisfactorily.
