Alturas Municipal Airport
Aircraft Accident/Incident Report

Alturus, California 96101
Friday, September 15, 2000 17:50 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was unable to locate a windsock while circling the uncontrolled airport. He had obtained a preflight weather briefing from the FAA Red Bluff Flight Service Station with no adverse weather conditions noted; no local area wind information was obtained. He established a left pattern for runway 31; on final approach he determined there was a left crosswind for which he established a crab angle. On touchdown, the left wing came up, resulting in the right wing scraping the runway and a loss of directional control.

NTSB Probable Cause Narrative

The pilot's inadequate compensation for the wind, and his failure to maintain directional control of the airplane during landing. A factor was the faded improperly maintained windsock.
