Primary finding
Probable cause
The pilot's failure to maintain directional control during the landing roll.
Investigator assessment
Analysis narrative
The pilot reported that during the landing roll, with the tailwheel on the ground, the airplane veered to the left. The pilot applied right rudder and brake. The airplane immediately "turned hard right" as the pilot applied left rudder and brake. Despite the pilot's control inputs, the airplane continued to veer to the right. The pilot stated that the airplane "hopped sideways on the left main gear," turned 180-degrees to the right, and the left main landing gear collapsed. Subsequently, the left wing tip impacted the ground, which resulted in structural damage to the wing spar. The pilot reported no mechanical anomalies with the airplane's flight control or brake systems prior to the accident.
