Probable cause

The pilot's failure to adequately compensate for the wind conditions. A factor contributing to the accident was gusting winds.

Analysis

The pilot stated that the airplane encountered a gust of wind as the pilot was flaring for a three-point, full-stall landing on runway 14. The pilot stated that the gust 'lifted the left wing' and the tail veered to the right. The pilot attempted to maintain directional control of the airplane and was not successful. During the pilot's attempted corrections, the airplane veered off the runway. The right main landing gear collapsed as it encountered rough terrain. The airplane's right wing impacted the ground and the airplane flipped over onto its right side. No preimpact mechanical deficiencies were reported.

Factual narrative

On May 10, 1997, about 1030 Pacific daylight time, N8224A, a Cessna 170B, operated by the owner/pilot, collided with terrain while landing at the Ontario Municipal Airport in Ontario, Oregon. The airplane was substantially damaged. The private pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed and no flight plan had been filed. The personal flight departed from Emmett, Idaho, and was conducted under 14 CFR 91.

During the pilot's attempted corrections, the airplane veered off the runway. The right main landing gear collapsed as it encountered rough terrain. The airplane's right wing impacted the ground and the airplane flipped over onto its right side. No preimpact mechanical deficiencies were reported by the pilot.
