The airplane was substantially damaged during a ground loop while landing. According to the pilot he had checked the weather 20 minutes before the accident and had estimated the crosswind at 9 knots. The pilot stated that during the landing roll the airplane passed a row of hangars. He reported that as the airplane passed the last hangar the left wing started to "float." The pilot attempted to apply corrective actions but was unable to do so. The airplane subsequently ground looped.
