Probable cause

The pilot in command's failure to adequately compensate for wind conditions during the landing. Factors contributing to the accident were a crosswind and gusty wind conditions.

Analysis

After overflying the airport and observing the windsock showing a strong, westerly crosswind, the pilot executed an approach to runway 16. Immediately before touchdown the pilot encountered three successive gusts during which the aircraft departed the runway environment to the east. During the final gust a wing stalled and the aircraft impacted the ground.

Factual narrative

On May 11, 1996, approximately 1130 hours Pacific daylight time, an Aeronca 7BCM, N2606Z, being flown by a private pilot, was substantially damaged during a loss of control on landing at the Bend Municipal airport, Bend, Oregon. The pilot and pilot-rated rear-seat passenger sustained minor injuries. Visual meteorological conditions existed at the time and no flight plan had been filed. The flight, which was personal, was to have been operated under 14CFR91, and originated from Nampa, Idaho, stopping at Burns, Oregon, and departing approximately 0945 local.

The pilot reported that upon arriving at the destination she overflew the airport and observed the "wind was blowing out of the West and the sock was straight out." She then entered the pattern and executed an approach to runway 16. Immediately before touchdown the aircraft encountered a gust which she successfully corrected for. This was followed by a second gust which blew the aircraft left off the runway. The pilot reported that a third gust lifted the right wing and then one wing stalled during which the left wingtip impacted the ground. The aircraft executed a half a cartwheel before coming to rest.

The pilot reported that there were no mechanical malfunctions with the aircraft.
