Analysis

The pilot was landing a tailwheel equipped airplane on a hard surface runway. The airplane was equipped with 26 inch tundra tires. During the landing roll, the airplane began to veer to the left. The pilot applied right rudder, and right brake, but the airplane continued to veer to the left, and the right wing struck the ground. The airplane then nosed over. The airport's automated weather observation system was reporting the wind conditions as 010 degrees at 7 knots. Following the accident, the pilot reported the wind conditions varied widely between 030 to 300 degrees, with wind gusts to 15 knots.
