Airworthiness Directive · Amendment 39-13046 · Pratt & Whitney Canada PW500 Series Turbofan Engines
Pratt & Whitney Canada PW500 Series Turbofan Engines
This airworthiness directive (AD) is applicable to Pratt & Whitney Canada (PWC) PW530A, PW535A, and PW545A turbofan engines with flexible fuel tubes part numbers (P/N's) 30J2285-01, 3054416-01, and 30J2323-01 installed. These engines are installed on, but not limited to Cessna Citation model 550 "Bravo", model 560XL "Excel", and model 560 "Encore" airplanes.
This amendment adopts a new airworthiness directive (AD) that is applicable to Pratt & Whitney Canada (PWC) PW500 series turbofan engines. This action requires a one-time visual inspection and re- marking, or in lieu of inspection, replacement of certain part numbers (P/N's) of the flexible fuel tube located between the fuel/oil heat exchanger and the integral fuel control unit-fuel pump. This amendment is prompted by reports of fuel found dripping from engine nacelles caused by leaking flexible fuel tubes. The actions specified in this AD are intended to prevent a fire in the engine nacelle.
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.
