Analysis

The pilot in the tailwheel-equipped airplane reported that he landed the airplane on the turf runway in variable wind conditions. During the landing roll, the airplane veered right and exited the right side of the runway. The airplane struck a runway cone and a windsock pole. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The weather reporting station at the nearest airport, about 24 miles from the accident site, reported that, about the time of the accident, the wind was from 340° at 7 knots. The pilot landed the airplane on runway 36.
