Reno, NV, USA
N9857B
Champion 7FC
The aircraft had been converted from a tricycle landing gear configuration to a tail wheel configuration. The accident occurred as the pilot performed a wheel landing and, although the wind was reported calm, he thought there was a gust because the aircraft veered to the left, then reversed to the right, and ground looped. The main landing gear collapsed and the left wing contacted the runway. The pilot reported that on the previous landing the wind sock was "dead calm"; however, during the accident landing the wind sock showed a left crosswind. At the nearest weather reporting point, 11 miles distant, the surface wind speed was reported to have been 3 knots.
