This amendment adopts a new airworthiness directive (AD) that is applicable to Pratt & Whitney Canada PW100 series turboprop engines. This action requires a visual inspection of the two gas generator case drain ports to ensure that they are connected to drain lines or capped in accordance with the applicable aircraft installation configuration. This amendment is prompted by a report of a nacelle fire. The actions specified in this AD are intended to prevent a nacelle fire caused by fluid leaking from the gas generator case drain ports.
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.
