Chances are, if you fly turboprop-powered aircraft, you have some time behind the Pratt & Whitney PT6 series engines. My own introduction to the legendary engine came when I first flew the Cessna Grand Caravan—and the marriage of the 182-like handling with the performance and reliability of the PT6A-114A (in that case) made the airplane an easy transition and a fast friend. Many pilots feel the same way, whether it’s while flying a Piper M600, an Epic E1000, or a Daher TBM 940—and retrofits have even used the engine to breathe new life into venerable airframes such as the Douglas DC-3, in the guise of the Basler BT-67 conversion.
