The airplane veered right, and he added full aileron, rudder, and brake to recover to no avail. The pilot stated he heard a "loud noise," the airplane veered sharply, and it then came to rest on an adjacent taxiway. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation station at the airport reported that, about 23 minutes before the accident, the wind was from 330° at 10 knots. The airplane landed on runway 32. ## Factual narrative The pilot of the tailwheel-equipped airplane reported that, during the landing roll, a wind gust from the left caused the left wing to rise.
