What happened
According to witnesses, the pilot took off and performed a 180° descending turn back toward the airport. He then flew a high-speed, low altitude pass along the runway before pulling up and descending into the trees. One witness reported that the airplane appeared to enter a roll as it descended into the trees near the end of the runway.
Postaccident examination of the airframe and engine revealed no evidence of a preimpact mechanical malfunction or failure that would have precluded normal operation. Metallurgical examination of a propeller blade tip that its separation from the propeller blade was likely the result of impact-related damage.
Witnesses who knew the pilot and frequently saw him take off stated that after takeoff he typically made a 180° turn, and flew a high-speed low pass over the airport before climbing and entering a barrel roll. The pilot’s routine performance of high-speed flyovers and low-altitude aerobatics was indicative of high-risk behavior. Based on the available information, the pilot likely lost control of the airplane while performing an aerobatic maneuver at an altitude too low to recover.
