Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that the AWOS weather reported strong gusts of 15 up to 25 kts straight down the runway. At approximately 20 ft agl, he experienced moderate turbulence and elected to abort the landing and attempted to climb. However, as the airspeed was decreasing the airplane was not gaining altitude. The pilot experienced another strong wind gust which put the airplane into a nose down and right wing low attitude, which he was unable to control and collided with the runway substantially damaging the right wing. The pilot stated that there were no preimpact mechanical malfunctions or failures that would have precluded normal operations.
