Analysis

The pilot of a tailwheel-equipped airplane reported that he decided to land on an off-airport gravel bar. During the landing roll, the pilot reported that a "tailwind gust" lifted the airplane's tail and the airplane nosed over. The right wing lift strut and windscreen were substantially damaged. The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation.
