He dropped the tail and started to apply the brakes when his right foot slipped off the rudder pedal, he was wearing cowboy boots. The plane veered left and he applied full left brake to avoid nosing into a drainage ditch head first. During this turn the tail wheel struck a boulder and the right wing tipped down and struck the ground.

The pilot stated that the airplane and engine had no mechanical failures or malfunctions during the flight.
