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.
