Accident Overview
A pilot of a tailwheel-equipped airplane reported an incident during the landing roll. As the airplane touched down and rolled along the runway, the right wing suddenly rose, initiating a loss of directional control.
Pilot Actions
The pilot responded by applying aileron and rudder inputs to counteract the wing rise and correct the airplane's path. Despite these efforts, the left wing subsequently struck the ground as the airplane entered a ground loop.
Aircraft Damage
The left wing sustained substantial damage as a result of the impact with the ground. No other damage to the airframe was reported.
Mechanical Status
The pilot stated that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The aircraft was reported to be functioning as expected prior to the incident.
