Narrative:At the completion of a simulated autorotation maneuver the main rotor severed the tailboom. The check airman reported that at approximately 20 feet above ground level he "determined the sink rate was excessive" and he decided to perform a "power recovery." The check airman stated, "I repositioned my hand, started opening the throttle while leveling the aircraft and applying a cushioning pitch pull." The helicopter impacted off the left side of the runway with "the skids aligned with the direction of travel slightly aft skid low." The check airman reported, "The aircraft rocked up onto the toes of the skids and I increased collective pitch and applied aft cyclic, when I did the main rotor impacted the tailboom severing it."
Probable Cause: The excessive descent rate that required an abrupt flare, resulting in the main rotor severing the tailboom.
