What happened
During the landing phase of flight, a private pilot was operating a tailwheel airplane on a warm asphalt runway. As the aircraft entered the landing roll, it suddenly lurched to the right. The pilot was unable to regain directional control of the aircraft.
As the excursion continued, the aircraft struck the runway with its left wing and propeller. The sequence ended with the aircraft coming to a rest in a nose-down position on the runway. The pilot reported no injuries following the event.
Findings
The aircraft was equipped with oversized main tires. The pilot noted that the combination of these large tires and the warm temperature of the asphalt runway surface may have contributed to the difficulty in maintaining directional control during the landing roll. There were no pre-accident mechanical problems reported with the aircraft.
