NTSB narrative
The pilot reported that the tail wheel equipped airplane nosed over during landing rollout on the grass runway. He informed a Federal Aviation Administration inspector that the runway surface varied with both wet and dry areas, which caused a variable braking action. The pilot noted that the accident might have been prevented with more careful brake application. He stated that there were no failures or malfunctions with the airplane before the accident.
Probable cause
The pilot's failure to maintain control of the airplane while braking during landing rollout.

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.
