NTSB Narrative Summary Released at Completion of Accident

During an instructional flight, the flight instructor rolled the throttle to idle. The pilot lowered the collective and entered an autorotation. At first, the pilot did not think he was going to make his intended touchdown point, and wanted to increase airspeed, but the instructor told him to slow the helicopter to 50 knots. The pilot applied aft cyclic, and airspeed decreased to about 40 knots. The pilot was now sure he would not make his intended touchdown point by maintaining 50 knots, so he lowered the nose. As airspeed increased, the pilot realized he was going to overshoot, so he initiated a left, and then a right turn to lose altitude. The pilot initiated a flare, applied initial collective, and then used additional collective to cushion the landing. Rotor RPM decayed during the landing sequence, and the helicopter touched down hard on the aft part of the skids, and then rocked forward, doing substantial damage to the tailboom, and main transmission mounts.

NTSB Probable Cause Narrative

The flight instructor's delay in applying remedial action. A factor in the accident was the pilot allowing the rotor rpm to become too low during the deceleration and touchdown phase of the autorotation.
