On January 21, 1995, a Stinson 108-2 (registration N9359K) operated by David E. Hennington was involved in an aviation accident near Lodi, CA. Investigators recorded the probable cause as: The pilot's failure to maintain directional control during the landing rollout due to a left crosswind. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During rollout on runway 26, the airplane encountered a left crosswind and veered off the pavement, entering a ditch and nosing over. The pilot reported no mechanical issues.
What happened
The pilot executed a traffic pattern approach and landed using runway 26. During the rollout phase, the aircraft encountered an estimated 10-knot left crosswind from approximately 180 degrees. As a result of the wind conditions, the airplane veered off the runway surface, entered a ditch, and nosed over. The pilot reported to a responding sheriff that he had landed downwind. He stated that he had not experienced any mechanical problems with his aircraft prior to the incident.
The investigation
The investigation focused on the circumstances surrounding the ground loop and subsequent damage. The pilot's statement indicated no pre-landing mechanical failures. The primary factor identified was the crosswind component during the landing rollout.
Findings
The accident occurred due to the left crosswind encountered during the landing rollout, which caused the aircraft to leave the runway pavement. The pilot's admission of landing downwind suggests a potential loss of directional control authority in those specific wind conditions.
Probable cause
The pilot's failure to maintain directional control during the landing rollout due to a left crosswind.
