Analysis

The airplane nosed over during landing. The pilot stated that during the landing roll he, "heard a double clunking sound [and] felt my upper body go forward [and] the tail wheel lifted." He said that the airplane skidded nose down before ultimately nosing over. The pilot reported that the brake clip that holds the brake disk in place, "came off and lodged in the wheel causing an abrupt [and] harsh drag on [the] right wheel." The pilot listed having 482 hours of experience is the same make and model airplane as the accident airplane.
