The pilot in the tailwheel-equipped airplane reported that prior to landing on the narrow, gravel surface airstrip, the airplane encountered a gust of wind from the right that "pushed me to the left a few feet." The airplane's left wing contacted the brush on the left side of the airstrip and the airplane exited the left side of the runway. The airplane descended a 2-foot ditch and stopped. The airplane sustained substantial damage to the left wing spar.

The pilot reported that the wind condition was variable and gusting to 8 knots. Additionally, he reported that the skies were clear, and that the visibility exceeded 10 miles.

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