What happened
Prior to departure, the pilot reviewed automated weather information for the airport and taxied the aircraft to the run-up area. The pilot noted awareness of a crosswind originating from the left side before beginning the takeoff roll. During the takeoff sequence, the pilot reported encountering a gust of wind, after which they had no memory of the subsequent events.
A witness observed the aircraft on short final when the right wing suddenly lifted into the air and the left wing made contact with the ground. This impact caused the airplane to pivot on its left wing, ultimately coming to rest in an inverted position.
Findings
At the time of the accident, the Automated Weather Observing System (AWOS) was out of service. However, the airport manager estimated winds were from 290 degrees at seven to eight knots with gusts. An eyewitness estimated that winds were gusting between 10 and 15 knots from the pilot's left side, noting that the airport flag was extended straight out.
