•Regarding Docket No. FAA-2008-1131; Directorate Identifier 2008-NE-37-AD. •NPRM for AD implementation of PW2000 series engines • FAA Proposed action: “We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. We are proposing this AD, which would require performing an FPI of the hub for cracks and an OCI of the blade retention slots on the forward and aft sides of the HPT 2nd stage hub for conformance to dimensional tolerances at the next HPT overhaul after the effective date of this AD.” • FAA Summary of requirement; You are responsible for having the actions required by this AD performed at the next HPT overhaul, unless the actions have already been done. • FedEx Fleet Impact: None, FedEx fleet of PW2000/757 aircraft will follow the Boeing AMM and Pratt & Whitney Engine Manual for required maintenance and performance specifications. At Next Engine Shop visit and HPT is dis-assembled to piece part level the AD will be complied with.
