According to the pilot of the weight shift aircraft, he noticed the wind speed increasing and decided to return to the airport. While on final approach to runway 18, approximately 30 feet above ground level, the aircraft incurred “turbulence,” it veered to the left, and the pilot unsuccessfully attempted to gain altitude in order to avoid colliding with trees. The aircraft settled into the trees, which resulted in substantial damage to the keel and spar of the aircraft. The pilot reported no preimpact mechanical malfunctions or failures with the aircraft that would have precluded normal operation. Winds, recorded at an airport 10 miles to the west of the accident location, about the time of the accident, were from 150 degrees at 7 knots.
