Probable cause

The pilot's inadequate compensation for the wind conditions and failure to maintain airplane control during the landing flare. Contributing to the accident were the gusty wind conditions.

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 he departed with the intention of flying around the traffic pattern to maintain his flying currency. After a few minutes, he approached runway 23 and attempted to land. The pilot stated that the wind was from a northerly direction at 7-10 knots and was gusty. The pilot entered a sideslip to maintain runway alignment. As the airplane crossed the threshold, it suddenly lost lift and descended until it impacted the runway, bounced, and then nosed over. The airplane came to rest in an inverted attitude adjacent to the south side of the runway, about 350 feet upwind of the runway's landing threshold. The airplane's rudder and wing lift struts were bent. The pilot reported that no mechanical malfunctions occurred with the airplane and that its engine operated normally. The pilot also reported that he was flying his airplane under his sport pilot license and that no aviation medical certificate was required.
