Accident Overview
Witnesses at the airport observed an airplane make a low pass down the runway. After the low pass, the airplane pulled up to an altitude of approximately 300 feet above ground level (AGL) and rolled to the left. One witness reported that when the airplane reached the inverted position, its nose was pointed downward. Another witness stated that the airplane completed an aileron roll, began a second roll, and upon reaching the inverted position, pitched down "just like a split S." Both witnesses indicated they had observed the pilot rolling the airplane many times before.
Impact and Wreckage
Witnesses off the airport reported seeing the airplane's right wing tip and nose simultaneously impact the ground. The accident site was located about 1/4 mile from the departure end of the runway.
Examination
Examination of the airplane wreckage at the accident site revealed no evidence of any preimpact mechanical discrepancies.
