Airworthiness Directive · Amendment 39-11392 · Pratt & Whitney JT8D-200 Series Turbofan Engines
Pratt & Whitney JT8D-200 Series Turbofan Engines
Superseded. A later AD replaced this one: AD 2004-26-04. Comply with the one in force.
Pratt & Whitney (PW) Model JT8D-209, -217, -217A, -217C, and -219 turbofan engines, installed on but not limited to McDonnell Douglas MD-80 series airplanes.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Pratt & Whitney JT8D-200 series turbofan engines, that currently requires installation of high pressure turbine (HPT) containment hardware. This amendment requires removing low pressure turbine (LPT)-to-exhaust case bolts and nuts and replacement with improved LPT-to-exhaust case bolts and nuts, and installation of improved HPT containment hardware. This amendment is prompted by uncontained HPT events resulting from HPT shaft fractures and LPT flange separations resulting from LPT blade failures. The actions specified by this AD are intended to prevent damage to the airplane resulting from uncontained engine debris following an HPT shaft fracture or an LPT blade failure.
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.
