Common Information
TASK 72-31-11-200-001-C00 Annulus Filler - Examine The Annulus Filler
General
This TASK gives the procedure for the inspection of the annulus fillers. For the other LP compressor blades and fillers parts, refer to TASK 72-31-11-200-000 (INSPECTION/CHECK-000).
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 the SPM TASK 70-11-03-100-501.
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 Step. Do the test before the part is visually examined.
Do not discard any part until you are sure there are no repairs available. Refer to the instructions in the 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 paractices and processes referred to in the procedure by the TASK/SUBTASK numbers are in the SPM.
