On April 24, 2006, at 1440 Pacific daylight time, a Beech P-35 Bonanza, N8689M, sustained substantial damage during landing at the Bandon State Airport, Bandon, Oregon. The airplane is owned by the pilot and was being operated as a visual flight rules (VFR) personal flight under the provisions of Title 14, CFR Part 91, when the accident occurred. The commercial pilot and pilot rated passenger aboard the airplane were not injured. Visual meteorological conditions prevailed for the flight that originated at Bandon State approximately 40 minutes prior to the accident. No flight plan was filed for the flight. In a written statement dated May 1, the pilot reported that the approach to landing was "normal" until the airplane crossed the runway threshold. He stated that when the airplane crossed the landing threshold a "large westerly gust sharply lifted the right wing." The pilot reported that he applied corrective actions, however the aircraft's left wing contacted the ground approximately 20-25 feet east of the runway and the airplane "cartwheeled." The pilot reported that the winds were from the southwest at 15 knots with "gusts."
