Analysis

According to the pilot, prior to commencing his approach to land the reported wind at the airport was variable at 5kts. During landing the tail of the airplane rose and shifted to the left at touchdown. The pilot attempted to recover, but the airplane ground looped, resulting in substantial damage to the left and right ailerons. Upon exiting the aircraft, the pilot observed the windsock indicating a quartering tailwind. The pilot reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation.
