Aircraft involved

Probable cause & findings

The pilot's failure to maintain directional control during landing, which resulted in a runway excursion and nose-over when the right wheel encountered mud.

Factual narrative

The private pilot reported that the purpose of the flight was to practice stop-and-go landings. The airplane took off and made a standard traffic pattern to land. The airplane touched down on the numbers with both main wheels. When the tailwheel touched down, the pilot felt a gust of wind from the east which tipped the left wing down. He attempted to correct with right aileron, but when the wings became level the right wheel exited the runway surface and sunk into the mud. The airplane nosed over substantially damaging the rudder. The pilot reported that there were no mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
