## Analysis

The pilot reported that he had landed and was beginning to taxi when a gust of wind lifted the left wing. He added engine power and attempted to correct; however, he was unable to maintain control. The airplane subsequently departed the runway pavement, encountered a ditch, and overturned. The pilot stated that there were no failures or malfunctions associated with the airplane before the accident. He reported a 50-degree left crosswind at 10 knots about the time of the accident.
