Incident Overview
While circling an uncontrolled airport, the pilot was unable to locate a windsock to determine wind direction and speed. The pilot had obtained a preflight weather briefing from the FAA Red Bluff Flight Service Station, which noted no adverse weather conditions. However, no local area wind information was obtained before commencing the approach.
Approach and Landing
The pilot established a left-hand traffic pattern for runway 31. On final approach, he determined the presence of a left crosswind and established a crab angle to compensate. During touchdown, the left wing of the aircraft came up, causing the right wing to scrape against the runway surface. This resulted in a loss of directional control of the aircraft.
Contributing Factors
No contributing factors beyond the pilot's inability to locate the windsock and the subsequent crosswind conditions are detailed in the source. The preflight briefing did not indicate adverse weather, but specific local wind information was not sought.
