Location: Denver, CO
Accident Number: GAA19CA045
Date & Time: 10/27/2018, 1200 MDT
Registration: N4500W
Aircraft: Piper PA18
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries:2 None 
Flight Conducted Under: Part 91: General Aviation - Instructional 

The pilot under instruction was in the tailwheel-equipped airplane with 26-inch bush wheels and reported that he observed indications of a head wind during the approach to the asphalt runway. He asserted that when the airplane touched down on the mains, he noticed that the windsock had shifted 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 to the left and 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 automated surface observing system at the airport reported that about the time of the accident, the wind was from 280° at 25 knots and gusting to 30 knots.

The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
