Analysis

At the end of the airplane's landing roll on a road, the pilot reports that a very strong gust of wind lifted the right wing so that the left wing contacted the ground. The pilot corrected, and the airplane veered to the right. The right wing leading edge contacted a small cedar tree. As the airplane came to a stop, the propeller contacted the ground. The left wing, left elevator, and right wing sustained damage.
