What happened
While attempting to turn onto runway 24, the pilot encountered strong and gusty winds that pushed the aircraft toward the right side of the runway. As the right (downwind) wheel moved off the paved surface, the left wing lifted. This motion caused the propeller and the right wing tip to strike the ground, ultimately resulting in the aircraft flipping into an inverted position.
The pilot estimated the wind was originating from 220 degrees at 30 knots. This flight marked the pilot's first flight following the installation of a wing lift modification designed to extend the wing tips.
Findings
During the investigation, it was noted that the aircraft had been out of service in a maintenance shop for approximately 90 days prior to the accident. The pilot reported that he felt he had lost "the edge" due to a lack of recent flight time. Additionally, the pilot stated he was not familiar with the new handling characteristics resulting from the recently installed wing tip extensions.
