The pilot of the tailwheel and tundra tire-equipped airplane reported that, during approach to land on a dirt field, about 10 ft off the ground, the airplane yawed to the right, the right wing aerodynamically stalled and impacted terrain.

The airplane sustained substantial damage to the fuselage and both wings.

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

The pilot reported that the wind was variable at 10 to 13 knots. He added that, after exiting the airplane, he observed that the wind was "swirling" and not constant. He assumed that he encountered a quartering tailwind gust. The pilot was landing the airplane to northwest.
