NTSB narrative
The pilot had landed the tailwheel-equipped airplane up-slope, on a vegetation covered unimproved runway. He reported that he had landed at the same location four days prior without incident. While back taxiing on the downhill portion of the runway the airplane began to accelerate. The pilot applied the main wheel brakes in an effort to slow the airplane, but it continued into a soft muddy section, and it subsequently nosed over. The airplane sustained substantial damage to the vertical stabilizer, rudder, and left wing lift strut. The pilot stated that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation.
In the recommendation section of the NTSB Accident/Incident Reporting Form 6120.1, the pilot stated that the accident may have been avoided if he had taxied at a slower speed, or if he had been more cautious of the changing runway conditions.
Probable cause
The pilot's excessive taxi speed, which resulted in a loss of 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: investigation status. 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.
