NTSB narrative

The pilot reported that shortly after takeoff for the local area flight the engine's rpms decreased and he felt a loss of thrust. The pilot made a turn in an attempt to make an emergency landing to another runway; however, the airplane touched down hard and short of the runway, substantially damaging the airplane. Postaccident examination revealed that the sprag clutch failed, preventing the engine from turning the propeller and causing a loss of thrust.
