Probable cause

The pilot's failure to compensate for the existing wind conditions. A contributing factor was the prevailing crosswind.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The 1,019-hour private pilot lost control of the tailwheel-equipped airplane after encountering a wind shift while landing on runway 14. The pilot reported that after checking the automated weather service station and windsock at the arrival airport, he attempted to land the single-engine airplane with a prevailing right crosswind on the dry 5,002-foot long asphalt runway. The pilot reported holding the control inputs to correct for the crosswind and suddenly encountering a wind shift from the left. The pilot indicated in the accident report (NTSB Form 6120.1), that after the main wheels touched down, the left wing lifted and the nose of the airplane turned left into the wind. The airplane then exited the left side of the 75-foot wide runway and initiated a ground loop on the wet grass adjacent to the runway. The fuselage of the airplane sustained structural damage and the pilot and passenger were not injured. The automated weather observation station on the field reported scattered skies with 10 miles visibility, with winds from 270 degrees at 6 knots.
