The pilot of the tailwheel-equipped airplane stated that he made a "three-point" landing on the asphalt runway. After touchdown, the airplane began to "pull" to the right, and the pilot corrected by applying left rudder. "Within a split second," the airplane turned "hard left,” collapsing the right main landing gear. The right wing impacted the runway and sustained substantial damage. The pilot reported there were no mechanical malfunctions or failures. The pilot had received a tailwheel endorsement the day prior to the accident, and reported 5 hours of flight time in the accident airplane. He also stated to a Federal Aviation Administration inspector that he had received limited exposure to operating the tailwheel-equipped airplane on hard-surface runways, as his tailwheel flight instruction was conducted mostly from turf runways.
