Airworthiness Directive · Amendment 39-13258 · Pratt & Whitney JT8D-200 Series Turbofan Engines
Pratt & Whitney JT8D-200 Series Turbofan Engines
This airworthiness directive (AD) applies to Pratt & Whitney (PW) JT8D-209, -217, -217A, -217C, and -219 series turbofan engines. These engines are installed on, but not limited to McDonnell Douglas MD-80 series airplanes.
This amendment adopts a new airworthiness directive (AD) that applies to Pratt & Whitney (PW) JT8D-209, -217, -217A, -217C, and -219 series turbofan engines. This amendment requires removal and replacement of protective coating of the 7th and 9th through 12th stage high pressure compressor (HPC) disks and the 8th stage HPC hub, initial and repetitive inspections for corrosion pits and cracks, and removal from service as required. This amendment is prompted by reports from operators of cracks observed in JT8D engine steel HPC disks. We are issuing this AD to prevent fracture of the 7th and 9th through 12th stage HPC disks and 8th stage HPC hub, resulting in uncontained engine failure and 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.
