AD: Pratt & Whitney

AD NUMBER: 2009-04-18

MANUFACTURER: Pratt & Whitney (PW) JT9D-7 Series Turbofan Engines
SUBJECT: Airworthiness Directive 2009-04-18

 

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for PW models JT9D-7, -7A, -7AH, -7H, -7F, and -7J turbofan engines. This AD requires initial and repetitive borescope inspections of the 2nd stage high-pressure turbine (HPT) rotor and stator assembly. This AD results from an uncontained failure of a 2nd stage HPT rotor disk that caused the engine to separate from the airplane. We are issuing this AD to prevent failure of the 2nd stage HPT rotor disk, which could result in uncontained engine failure, damage to the airplane, and the engine separating from the airplane.
