The pilot reported that before landing on an unimproved airstrip, he tried to identify the wind direction using a ribbon located at the high point along the airstrip that was above the treetops. He also over flew the airstrip both ways at about 1,500 ft to verify what the ribbon was showing. During the landing, the airplane was not aligned with the airstrip, and the left main landing gear touched down first, which imposed a significate side load to the left main landing gear assembly. After the landing, the pilot noticed that he had landed with a quartering tailwind.

The airplane sustained substantial damage to the fuselage and right-wing rear spar.

The pilot reported no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The pilot was landing the tailwheel and tundra tire-equipped airplane on a remote unimproved airstrip. While on final approach and just before touchdown, a gust of wind pushed the airplane to the left. The left wing contacted alder brush and the airplane veered to the left and ground looped sustaining substantial damage to the right wing. The pilot reported no preaccident mechanical failures or malfunctions that would have precluded normal operations.

In the recommendation section of the NTSB Accident/Incident Reporting Form 6120.1, the pilot stated that the accident may have been prevented if he had waited for a day without gusting wind conditions.
