The pilot in the tailwheel-gear-equipped airplane reported that he was practicing takeoffs and landings and had accomplished a wheel landing on runway 27. During the landing roll, the tailwheel contacted the ground, and the airplane encountered a wind gust from the right. The pilot recalled that the right aileron was into the wind with left rudder and no power applied. The right wing rose, and the airplane began to weathervane. He added full engine power and full left rudder. The "right main" descended back to the ground, but the airplane exited the runway to the right. The airplane encountered a berm and became airborne. The airplane descended to the ground and spun about its nose to the left. The airplane sustained substantial damage to the left wing spar and the left main landing gear attachment points. The pilot reported that, when he checked the weather before he began practicing takeoffs and landings, the wind was from 320° at 10 knots but, about the time of the accident, the METAR reported that wind was from 350° at 15 knots gusting to 22 knots. The crosswind component was 18 knots. Per the National Transportation Safety Board Pilot Aircraft Accident Report, the pilot remarked that the accident could have been prevented by setting "personal limitations" and by checking the Automatic Terminal Information System "every two pattern practices." The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
