NTSB narrative
The flight instructor was returning from the practice area with his student on a Title 14, CFR part 91, instructional flight. The flight instructor said he landed the tailwheel-equipped airplane with a 8-11 knot quartering tailwind. He said as the airplane slowed, the tailwind blew the nose to the right, resulting in a ground-loop and nose-over. He also reported that the accident could have been prevented by not landing with a tailwind.
Probable cause
The flight instructor's decision to land with a tailwind, and his failure to maintain directional control during landing, resulting in a ground-loop and nose-over.

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: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
