General

This TASK gives the procedure for the inspection of the HP Compressor Rotor Blades Locking Nuts and Jacking Screws (matched pair type) SBE 70-0064 V2500/A1 series, E.I.S. V2500/A5 series and SBE 72-0560 V2500/Select series. Refer to TASK 72-41-15-200-000 for the other remaining parts.

Fig/item numbers in parentheses in the procedure agree with those given in the EIPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the EIPC.

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 72-41-15-100-000.

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.

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 must be discarded can be held although no repair is available. The repair of a discarded part can be shown to be necessary at a subsequent 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 the TASK/SUBTASK number are in the SPM.
