Read the full NTSB narrative
About three minutes after takeoff, the airplane's engine experienced a complete loss in power, but the propeller kept turning. Since the pilot could not get the engine restarted, he configured the airplane for a normal landing, and touched down in what appeared to him to be level snow-covered terrain. Upon touchdown, the airplane sank through about three feet of dense snow, which resulted in a rapid deceleration. Both the airplane's belly and the inboard portion of its wings suffered crushing damage. Inspection of the airplane's fuel storage and delivery systems, and the teardown inspection of the components of the turbocharger system did not reveal any evidence of an anomaly that would have kept the engine from producing full rated horsepower. The engine was successfully test run at various power settings up to a maximum of 2,400 rpm and 30 inches of manifold pressure.
