He attempted to correct for the right drift with a left rudder input, but the wind suddenly changed direction and the airplane veered to the left. He applied full brakes to stop the airplane from leaving the runway, but in the process the airplane nosed over. The vertical stabilizer, rudder, both wings, and cabin structure were substantially damaged. The pilot reported that there were no preimpact mechanical malfunctions or failures that would have precluded normal operation of the airplane. About 4 minutes before the accident, a local weather station reported that the prevailing wind was out of the southwest at 4 knots. About 16 minutes after the accident, the same weather station reported that the wind speed had increased to 8 knots, with 14 knot wind gusts. ## Factual narrative The pilot reported that after a normal touchdown the airplane drifted toward the right side of the runway.
