The NTSB's narrative final · quoted from the NTSB record

The solo airline transport pilot reported he was attempting to takeoff in a gusty, 90 degree left crosswind. He estimated the wind velocity as 18 knots, gusting to 23 knots. During the takeoff roll, he said a gust of wind lifted the left wing, and forced the airplane to the right, off the runway, and down an embankment, where it nosed over. The pilot said there were no preaccident mechanical problems with the airplane.
