Visual meteorological conditions prevailed at the time and no flight plan was filed for the operation. The aircraft sustained substantial damage to the wings and the fuselage structure surrounding the gear attach points. Neither the certificated private pilot nor his one passenger were injured. The flight originated at Oakland, California, on the day of the mishap at about 1330 hours as a personal cross country flight to Lakeport.
