General

This TASK gives the procedure for the inspection of the casing assembly. For the other parts of the scavenge oil filter housing assembly, refer to Inspection-000 TASK 79-22-43-200-400.

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

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 the SPM.
