Airworthiness Directive · Amendment 39-22513 · Turbine section
Pratt & Whitney Canada Corp. Engines
This AD applies to Pratt & Whitney Canada Corp. (P&WC) Model PW307D 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.
For engines with an HPT 2nd-stage disk, part number (P/N) 30P3182-01, with serial number (S/N) A004D8X1 or A004E9K3 installed, within 100 engine cycles after the effective date of this AD, remove the HPT 2nd-stage disk from service.
After the effective date of this AD, do not install any HPT 2nd-stage disk having P/N 30P3182-01 with S/N A004D8X1 or A004E9K3 on any engine.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
