Aircraft involved

Probable cause & findings

The pilot's failure to release brake pressure soon enough when his airplane skidded from wet grass onto dry terrain during an off-airport, full-stop landing. A factor was the change in terrain from wet grass to dry ground in the landing area.

Factual narrative

While landing in an open field covered with wet grass, the aircraft's main wheels started to skid when the brakes were applied. When the aircraft came in contact with drier terrain, the increase in braking effectiveness caused the tail wheel-equipped aircraft to nose over. Although the pilot tried to take remedial action by releasing all brake pressure, he was unable to do so soon enough to keep the aircraft from nosing over.
