"A review of amateur video taken at KOSH showed the
accident airplane in a left base turn to final for runway 18R. The
airplane appeared to overshoot the runway centerline during this
turn and then level its wings momentarily before entering a slight
right bank simultaneously as the nose of the airplane pitched up.
The airplane then turned left toward the runway centerline and
began a descent. During this descent the airplane’s pitch
appeared to increase until the airplane entered a right bank and
struck the grass area west of the runway in a nose down, right wing
low attitude."
