Accident Details
A pilot operating a tailwheel-equipped, restricted category agricultural airplane was landing to take on another load after an agricultural flight. He performed a three-point landing with full flaps and closed the throttle. During the landing roll, the airplane turned violently to the right and became very light on the gear. The nose had turned 45° to the right of the runway centerline. The pilot applied left brake and left rudder, then added power.
Sequence of Events
As power increased, the airplane rolled to the left. The left wing struck the ground, prompting the pilot to pull the throttle to idle and then apply reverse thrust and full brakes. Despite these actions, the airplane exited the runway and collided with a drainage culvert.
Damage
The airplane sustained substantial damage to the left wing spar and aileron.
Pilot Report
The pilot reported that about the time of the accident, the wind was light and variable, but dust devils were present. He also noted that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot stated that the accident could have been prevented by landing at a higher airspeed to maintain airflow over the rudder and by minimizing engine thrust.
