On July 24, 2005, at 1200 central daylight time, an amateur built Simmons GP-4, N619BS, collided with the runway following a loss of control while landing on runway 18 (8,002 feet by 150 feet, asphalt), at Wittman Field (OSH), Oshkosh, Wisconsin. The pilot and passenger were not injured. The airplane was substantially damaged. The 14 Code of Federal Regulations Part 91 personal flight was operating in visual meteorological conditions without a flight plan. The last leg of the cross country flight originated from Dayton, Ohio, at 1100 eastern daylight time.
The accident occurred as the pilot was arriving at EAA AirVenture 2005. The pilot reported he made a low turn onto final approach, possibly encountered a wind gust, and the airplane stalled. The pilot reported the winds as being from 270 degrees at 11 knots, gusting to 20 knots.
The winds reported at OSH at 1153 were from 250 degrees at 11 knots, gusting to 15 knots.
The pilot's failure to maintain airspeed sufficient enough to compensate for the gusty crosswind condition and prevent a stall during the landing flare. A factor associated with the accident was the gusting crosswind condition.
