Investigator assessment
Analysis narrative
The pilot of the tailwheel-equipped airplane reported that during a touch-and-go maneuver, the airplane veered left, and he corrected with right rudder pedal input. However, the airplane continued to veer left, and the pilot closed the throttle and applied the brakes. Subsequently, the airplane ground looped and the right wing impacted the ground, which resulted in substantial damage to the right wing and aileron. The pilot stated that about 15 minutes after the accident the wind report showed a quartering tailwind. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
