On June 12, 1994, at 1530 hours mountain standard time (MST), a homebuilt experimental Schumacher Swearingen SX-300, N2H, lost control and collided with the runway surface at the Kingman, Arizona, airport. The airplane was being operated as a personal flight by the pilot/owner. The airplane was substantially damaged. The certificated private pilot and passenger were not injured. The flight originated in Salt Lake City, Utah, at 1425 hours MST. Visual meteorological conditions prevailed and a VFR flight plan was filed. The pilot indicated he was monitoring the Kingman Airport UNICOM about 30 to 40 miles away from the airport. The pilot heard the pilot of a preceding Mooney airplane go-around on approach to runway 21 and land on runway 17. The pilot planned his approach to runway 17. On short final approach, the pilot decided the winds favored landing on runway 21, and attempted a go-around. The pilot added power and raised the flaps. The airplane settled and collided with the runway. In his statement, the pilot said that he inadvertently raised the flaps resulting in the airplane's loss of lift and subsequent settling on the runway. The pilot also indicated that there were no mechanical failures or malfunctions with the airplane before the accident. The automated weather station at the Kingman Airport was reporting winds from 190 degrees at 16 knots with peak gusts 29 knots at the time of the accident.
