The owner was operating the airplane under the provisions of 14 CFR Part 91. The airline transport pilot, the sole occupant, was not injured; the airplane sustained substantial damage. The personal cross-country flight departed San Carlos, California, about 1635. Day visual meteorological conditions prevailed, and no flight plan had been filed. The pilot stated that he was landing on runway 34. After landing, a gust of wind lifted the left wing off the ground, and the right wing contacted the ground. He said he couldn't control the airplane, and it departed the runway to the left. He shut the airplane down before it came to a stop.
