The pilot stated that the airplane bounced during touchdown and that he attempted a go-around, but the airplane veered to the left, which resulted in a ground loop. During the ground loop, the airplane's right wing impacted runway lighting and sustained substantial damage. The pilot reported that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation. ## Factual narrative The private pilot, who was also the owner of the tailwheel-equipped airplane was landing after a local flight.
