During the landing flare, the airspeed decreased, and just before touchdown, he applied aft yoke pressure to pin the tailwheel on the runway. As the main landing gear touched down, the airplane veered left, and it then 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 reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The solo student pilot in the tailwheel-equipped airplane reported that his intent was to accomplish a three-point landing.
