Aircraft involved

Probable cause & findings

The student pilot's failure to maintain directional control during the landing roll, which resulted in a runway excursion and collision with taxiway signage.

Factual narrative

The solo student pilot in the tailwheel-equipped airplane reported that his intent was to accomplish a three-point landing. During the landing flare, the airspeed decreased, and just prior to touch down, he applied aft yoke pressure to pin the tailwheel on the runway. As the main landing gear touched down, the airplane veered left, exited the left side of the runway and collided with taxiway signage. The airplane sustained substantial damage to the left main landing gear attachment points. The student pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
