What happened

The non-instrument rated commercial pilot departed on a cross-country flight in his high performance airplane. There was no record of the pilot receiving an official preflight weather briefing. However, the pilot may have obtained text weather information from a weather service while enroute. Images taken during the flight showed the airplane flying above an overcast cloud layer. Review of satellite imagery indicated that the overcast layer covered the area near the accident site and continued to the intended destination. Marginal visual to instrument meteorological conditions were reported near the accident site about the time of the accident. The investigation could not determine if there were breaks in the low overcast or how the pilot got below the overcast. However, a witness saw the airplane flying at a very low altitude and reported dark night conditions were present. The witness subsequently heard a loud crash, which he thought was the airplane, and called 9-1-1. The airplane was not on fire in flight and he did not see any subsequent fire or explosion. The smell of fuel was present in the area, which led emergency responders to the wreckage within a wooded area. The wreckage path through the woods was a nearly straight 150-ft descending path. Linear separations of tree branches and the S-shaped bending of a propeller blade were consistent with the engine producing power at impact. A postaccident examination of the wreckage did not reveal any preimpact anomalies that would have precluded normal operation of the airplane.
