Read the full NTSB narrative

According to the flight instructor, the student was setting up an approach near the reservoir. The approach angle was too steep, so the student discontinued the approach. The instructor stated that during the second approach, approximately 20 feet above the ground, the helicopter began to yaw to the right. She stated that she took control of the helicopter as it yawed approximately 180 degrees around. She established a stabilized hover and at this time, the "low rotor horn and light came on." The instructor stated that she "lowered the collective and rolled on the throttle to try and get the horn off and the rpms back up." She stated that the rpm never dropped below 95 percent. Subsequently, the helicopter "dropped straight down and hit the ground level" causing substantial damage.
