Airworthiness Directive · Amendment 39-13098 · Rolls-Royce Corporation (Formerly Allison Engine Company) 501-D Series Turboprop Engines
Rolls-Royce Corporation (Formerly Allison Engine Company) 501-D Series Turboprop Engines
Superseded. A later AD replaced this one: AD 2006-25-12. Comply with the one in force.
This airworthiness directive (AD) is applicable to Rolls-Royce Corporation (formerly Allison Engine Company) 501-D series turboprop engines. These engines are installed on, but not limited to Lockheed 188 series and 382 series turboprop airplanes, Airbus Industrie 377SG5-F (Super Guppy) airplanes, and Convair Models 340 and 440 airplanes which have Rolls-Royce corporation 501- D series turboprop engines installed under a Supplemental Type Certificate. These models are commonly referred to as Convair 580/ 580A or 5800 models.
This amendment adopts a new airworthiness directive (AD), that is applicable to Rolls-Royce Corporation (formerly Allison Engine Company) 501-D series turboprop engines. This amendment requires removal from service of certain turbine rotor components at reduced life limits. This amendment is prompted by the result of recalculated material properties by the manufacturer. The actions specified by this AD are intended to prevent uncontained turbine rotor failure resulting in in-flight engine shutdown and possible 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.
