On takeoff, the pilot experienced a loss of engine power preceded by the sound of loud 'pop.' He completed a forced landing on soft ground and the aircraft nosed over. During the post-accident teardown inspection of the engine, it was noted that four compressor/turbine blades had failed at the blade/butt interface. The failed blades were not standard manufacturer's replacement parts.
Probable Cause: The separation of four compressor/turbine blades resulting in a sudden loss of engine power with a subsequent forced landing into unsuitable terrain.
