Aviation Accident Summary GAA19CA045

Denver, CO, USA

Aircraft #1

N4500W

Piper PA18

Analysis

The pilot under instruction in the tailwheel-equipped airplane with 26-inch bush wheels reported that, during the approach, he saw indications of a headwind. He added that, when the airplane touched down on the main wheels, he noticed that the windsock had shifted and was indicating a direct left crosswind. Just before the tailwheel touched down, the left wing lifted, and he slowly added power to abort the landing. However, the airplane veered left, the right main landing gear collapsed, and the right wing struck the ground. The airplane exited the left side of the runway. The airplane sustained substantial damage to the right wing and the elevator. The airport's automated surface observing system reported that, about the time of the accident, the wind was from 280° at 25 knots, gusting to 30 knots. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
