TASK 75-24-49-200-101-D00 LP Turbine Active Clearance Control (ACC) Manifold And Tubes - Examine The Connector Tube Of The ACC - Inspection-000
General
This TASK gives the procedure for the inspection of the connector tube of the ACC.
Fig/item numbers in parentheses in the procedure agree with those used in the EIPC.
A ** following any 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 data.
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 the parts are examined. Refer to TASK TASK 75-24-49-100-100 (CLEANING-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 Step. Do the 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.
The practices and processes referred to by the TASK numbers in the procedure are in the SPM.
