He corrected with right rudder and brake which caused an overcorrection and he was unable to maintain directional control. During the accident sequence, the airplane ground looped and sustained substantial damage to the left wing. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that while landing the tailwheel-equipped airplane in a quartering tailwind, the airplane started to veer left upon touchdown.
