Analysis

The pilot was landing his tailwheel-equipped airplane at an off-airport beach landing site. During the landing flare, a gust of wind pushed the airplane to the left, and the left wing contacted the sloping beach, resulting in a ground loop. Both wings sustained substantial damage. The pilot reported that there were no preaccident mechanical anomalies with the airplane.
