The non-instrument rated pilot had just completed a night instrument flight lesson and elected to fly his airplane home. His flight instructor tried to get him to drive home but he said no, he could make it. The exact weather conditions he encountered could not be determined but the area was under a severe thunderstorm warning at the time. There were no records to show the pilot contacted any commercial or government weather service. The airplane was in a high speed, descending left turn, toward the direction of the departure airport, when it impacted a tree, a fence and fence post, a high voltage power line, and the ground. All of the wreckage was found along the wreckage path. No pre-impact problems could be found with the airplane, engine, or related components. The flight instructor said the airplane departed in VFR conditions. He also said that everything was operational on the airplane when they finished their instrument flight lesson.
