Common Information
TASK 72-32-51-200-002 Front Seal Runner Ring - Examine, Inspection-002
General
This TASK gives the procedure for the inspection of the seals.
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 the SPM TASK 70-20-01-200-501.
All the parts must be cleaned before any part is examined. Refer to TASK 72-32-51-100-000 (CLEANING-000).
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. Limits for cracks are given in the SUBTASK for each part.
A ** following repair referenced in this inspection indicates that the repair is not yet published in the current revision of the manual and the part must be rejected. Contact IAE for additional information concerning FAA approved repair date.
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 repairs have been completed satisfactorily.
The practices and processes referred to in the procedure by the TASK numbers are in the SPM.
