Turbine engine failure

September 10, 2014 - 11:00am

The FAA is adopting a new airworthiness directive for all Pratt & Whitney Canada PT6A-114 and PT6A-114A turboprop engines. It requires initial and repetitive borescope inspection of compressor turbine blades (CT), and the removal from service of blades that fail inspection. This AD was prompted by several incidents of CT blade failure, causing power loss and engine failure. The purpose of the AD is to prevent failure of CT blades, which could result in damage to the engine and the airplane.
