This AD is prompted by reports of multiple failures of the needle bearing installed in propeller governors having part numbers (P/Ns) P-W11-1 or P-W11-2, caused by self-generated debris from the needle bearing, which led to oil contamination. This AD requires replacement of the affected propeller governors with a redesigned propeller governor and prohibits installation of the affected propeller governors, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.

Pratt & Whitney Canada Corp. Engines
The FAA is adopting a new airworthiness directive (AD) for all Pratt & Whitney Canada Corp. (P&WC) Model PW307D engines. This AD is prompted by a root cause analysis of an event involving an uncontained failure of a high-pressure turbine (HPT) 1st-stage disk, on an International Aero Engines AG (IAE) Model V2533-A5 engine, that resulted in high-energy debris penetrating the engine cowling and an aborted takeoff. This AD requires removing certain HPT 2nd-stage disks from service and also prohibits installation of certain HPT 2nd-stage disks on any affected engine. The FAA is issuing this AD to address the unsafe condition on these products.
