The pilot reported in a written statement that, "about half way through the [landing] roll out I lost control of the aircraft and ground looped to the right." During the ground loop, the left main landing gear collapsed and the left wing impacted the runway.

The left wing sustained substantial damage.

The pilot failed to submit the National Transportation Safety Board NTSB Form 6120.1 Pilot/ Operator Aircraft Accident/ Incident Report after multiple requests.

An automated weather observation station, 5 nautical miles from the accident airport, about the time of the accident, recorded wind 120° at 20 knots, gusting 28 knots. The pilot reported that the landing was on runway 30.
