Airworthiness Directive · Amendment 39-14837 · Pratt & Whitney Canada (P&WC) PW535A Turbofan Engines
Pratt & Whitney Canada (P&WC) PW535A Turbofan Engines
This AD applies to Pratt & Whitney Canada (P&WC) PW535A turbofan engines that have fuel manifold, part number (P/N) 3025267-01, installed. These engines are installed on, but not limited to Cessna Airplane Co. model 560 Citation Ultra Encore airplanes.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as fuel manifold leakage that could result in engine fire, in-flight shutdown or damage to the airframe. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
Accomplish the following, in accordance with the instructions of P&WC Alert Service Bulletin PW500-72-A30314, dated September 27, 2006.
(1) For engines with fuel manifold, part number (P/N) 3052627-01, that has a total time since new (TTSN) of 1500 flight hours or higher: Within 50 flight hours or 60 days after the effective date of this AD, whichever occurs first, replace fuel manifold, P/N 3052627-01, with a serviceable part.
(2) For engines with fuel manifold, part number (P/N) 3052627-01, that has less than a total time since new (TTSN) of 1500 flight hours: Within 150 flight hours or 90 days after the effective date of this AD, whichever occurs first, replace fuel manifold, P/N 3052627-01, with a serviceable part.
A serviceable part is any replacement part except fuel manifold, P/N 3052627-01.
Note: This AD differs from the MCAI and/or service information as follows: (1) This AD is applicable to any engine that has fuel manifold, (P/N) 3052627-01, installed. (2) This AD allows replacing fuel manifold P/N 3052627-01 with a serviceable part as defined in paragraph (f) of this AD.
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.
