The pilot stated: "Accident occurred on landing runway 24. Approach stable (crabbed). Final approach speed 70 kts. Experienced ground effect, perhaps wind shifted to tailwind. Attempted go around - full power. Had not yet raised flaps (set to 2/3). Gust (crosswind - 300 degrees) of unknown speed (Winds apparently recorded at accident site - in sheltered hollow in excess of 20 mph) Lost control of aircraft which was blown into trees to left of runway...Pulled back power before impact...." According to an inspector from the Federal Aviation Administration (FAA), the pilot had been practicing takeoffs and landings on runway 24.
