Airworthiness Directive · Amendment 39-13490 · Pratt & Whitney Canada JT15D-1, -1A, and -1B Turbofan Engines
Pratt & Whitney Canada JT15D-1, -1A, and -1B Turbofan Engines
Superseded. A later AD replaced this one: AD 2023-03-12. Comply with the one in force.
This AD applies to Pratt & Whitney Canada (PWC) JT15D-1, - 1A, and -1B turbofan engines with certain impellers, part number (P/ N) 3020365, installed. These engines are installed on, but not limited to, Cessna Aircraft Company Models 500 and 501 airplanes.
The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney Canada (PWC) JT15D-1, -1A, and -1B turbofan engines with certain impellers part number (P/N) 3020365. This AD requires a one-time borescope inspection of the rear face of certain impellers for evidence of a machined groove or step, and repair or replacement of the impeller if a groove or step is found. This AD results from three reports of uncontained failure of the impeller. We are issuing this AD to prevent uncontained failure of the impeller 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.
