Factual narrative

On April 30, 1999, about 1600 Pacific daylight time, a Boeing Stearman, N56208, registered to and operated by the pilot, was substantially damaged while landing at Olympia Airport, Olympia, Washington. The aircraft was being operated as a 14CFR91 personal flight. Visual meteorological conditions prevailed and no flight plan was filed. The aircraft's last departure point was Chehalis, Washington, approximately 15 minutes prior to the accident. The private pilot and his passenger were not injured. The pilot stated that while on the landing rollout, on runway 17, the aircraft "swerved to the right" and became uncontrollable. The aircraft ground looped, causing damage to the left wing and aileron. At the time of the accident, the pilot reported the winds from 230 degrees at 10 to 12 knots. The pilot reported no mechanical failures or malfunctions with the aircraft at the time of the accident.
