Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

According to the pilot, after completing the final towing flight for the day, he returned land. He was cleared to land runway 34L and touched down "on the numbers and centerline with full flaps at 45 miles per hour(MPH)." The pilot reported that the airplane immediately weather vaned to the left, and headed for the left runway edge. He applied corrective countermeasures, "over corrected", and the airplane departed the right side of the runway. The airplane came to rest on the soft shoulder after completing 180 degrees of turn (ground loop). During the ground loop maneuver, the airplane sustained a bent outer left wing and aileron, and a bent left horizontal stabilizer. The pilot reported no mechanical malfunction/failure of the airplane prior to the accident and was able to taxi the plane to it's hangar after recovery. Wind conditions reported at the time of the accident were 290 degrees at 15 MPH gusting to 20 MPH with a wind shear warning in effect.
