issued SB PW300-72-24462 for initial inspection of affected HPC drum rotor assemblies for cracks.  In addition, the PW305 Maintenance Manual (MM) 05-20-00 was revised (Revision No.26) accordingly, to add a requirement for repeat inspection intervals.  A new P/N 31B6325-01, HPC drum rotor assembly, which is not susceptible to the subject cracking, is made available through SB PW300-72-24376, as a terminating action for the required repeat inspection.

             Recent data (Ref: Service Information Letter: PW300-093) indicates that a number of high-time Pre-SB-PW300-72-24376 HPC drum rotor assemblies (P/Ns 30B2478 and 30B2542), with potential for a hazardous disk failure in consequence of non-compliance with the inspection requirements, are still in-service.  This AD is issued to mandate the inspection of the affected P/N 30B2478 and 30B2542 HPC drum rotor assemblies in accordance with PW305-MM-05-20-00 requirements.

             This amendment corrects a typographical error in the P/N of HPC drum assemblies listed in Requirement 2 of this AD.

             The original issue of this AD became effective on 17 January 2008.
