Airworthiness Directive · Amendment 39-12924 · Pratt & Whitney JT8D-200 Series Turbofan Engines
Pratt & Whitney JT8D-200 Series Turbofan Engines
This airworthiness directive (AD) is applicable to Pratt & Whitney (PW) JT8D-209, -217, -217A, -217C, and -219 series turbofan engines that do not incorporate the fan exit guide vane case, part number (P/N) 805919 or 815377, and the improved durability and impact resistant fan duct assembly, P/N 805918-01. These engines are installed on, but not limited to McDonnell Douglas MD-80 and series airplanes.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Pratt & Whitney (PW) JT8D-200 series turbofan engines. This amendment requires the installation of stops on the fan exit guide vane case. This amendment is prompted by reports of the flange between the fan duct case and the fan exit guide vane case separating due to a fan blade fracture event. The actions specified by this AD are intended to prevent the flange between the fan duct case and the fan exit guide vane case from separating due to a fan blade failure. Separations of that flange could result in damage to the airplane.
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.
