The pilot of the tailwheel-equipped airplane reported that, while performing a wheel landing on an unimproved gravel airstrip, a gust of wind lifted the "weight off of [the] tires and initiated a skid." He added that, as the airplane settled back on the airstrip the tail rose rapidly due to the brakes being applied, and the airplane nosed over.
The airplane sustained substantial damage to the left wing lift strut and empennage.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
