General

This TASK gives the procedure for the inspection of the pins. For the other booster stage bleed valve and actuating mechanism parts, refer to TASK 72-32-70-200-000.

The policy that is necessary for inspection is given in the SPM TASK 70-20-00-200-501.

All the parts must be cleaned before any part is examined. Refer to the SPM TASK 70-32-70-100-000.

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 SUBTASK 72-32-70-230-057. Do the test before the parts are visually examined.

Do not discard any parts 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 discarded parts could be shown as necessary at a later date.

All the 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 TASK numbers are in the SPM.
