On the autorotation that culminated in the accident, both the instructor and student were at the controls. The instructor said, "it felt like the nose went down, the speed picked up and the rate of descent increased rapidly as if we were being pushed into the ground." The instructor leveled the helicopter as much as possible, but impacted the ground at a high rate of speed, destroying the aircraft.
