Analysis narrative
While performing a full stop landing to a wet grass strip in a tailwheel-equipped airplane, the pilot reported the airplane’s left wheel contacted soft soil. Directional control of the airplane was lost as it veered left and entered a water filled ditch on the left side of the runway resulting in the airplane nosing over and coming to rest inverted. The airplane’s vertical stabilizer and rudder sustained substantial damage. The pilot reported no mechanical malfunctions or failures with the airplane that contributed to the accident.
