Investigator assessment
Analysis narrative
The pilot reported that, while practicing touch-and-go landings, the tailwheel-equipped airplane touched down and immediately veered right. The pilot attempted to correct with opposite rudder and brake; however, the airplane exited the right side of the runway. During the excursion the airplane collided with an airport sign, and the right wing struck the ground, which resulted in substantial damage to the right wing and its lift strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. At the time of the accident, the pilot was landing the airplane on runway 18 with wind from 210° at 12 knots.
