NTSB narrative
The pilot reported that, "about half way through the [landing] rollout 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, recorded that, about the time of the accident, the wind was from 120° at 20 knots, gusting to 28 knots. The pilot reported that the landing was on runway 30.
Probable cause
The pilot's decision to land with a gusting tailwind and his subsequent failure to maintain directional control.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2017-05-07.
