Investigator assessment
Analysis narrative
The pilot reported that he landed with a quartering tailwind. When the tailwheel touched down, the wind pushed the tail to the right and the airplane ground looped. The airplane came to rest upright off the left side of the runway and sustained substantial damage to the right wing and fuselage. The pilot reported that there were no mechanical malfunctions or anomalies with the airplane that would have precluded normal operation.
