Brief:
The pilot performed another landing and had a firm touchdown. He said the aircraft immediately veered left and full right rudder had no effect. He said that his feet had slipped off the aircraft's toe brakes during the landing, so differential braking was not possible. The right main landing gear collapsed, and the right wing and aileron were bent. Postaccident examination of the tail wheel assembly revealed that the clevis which connected the left tail wheel spring to the wheel's steering arm was missing. Additionally, serpentine skid marks where found on the runway that appeared to be the result of a tailwheel shimmy. The pilot reported that the wind during his first landing was from 350 degrees at 6 knots.
