The student pilot was in the landing flare when the wind shifted from the left tailwind to a right tailwind. He said that the wing velocity suddenly tripled, and the airplane's right wing was thrown up at a radical angle. The airplane departed the left side of the runway and went down a steep slope, cartwheeled, and came to rest nose down.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The unforecasted sudden wind change, and the pilot's failure to maintain aircraft control. A factor was the down sloping terrain next to the runway.
