The NTSB's narrative final · quoted from the NTSB record

The flight instructor lost control of the helicopter while demonstrating the technique for recovering from a loss of tail rotor effectiveness while hovering over a helipad. After assuming the controls for the demonstration, the instructor noticed that the RPM was set too low, at 99 percent. The instructor elected to 'beep up' the RPM by stabilizing the cyclic with his left hand and 'beeping' the RPM with the right thumb. He was unsuccessful in beeping the RPM up on 2 attempts. On his last attempt, while manipulating the cyclic lever with his left hand and the RPM switch with the thumb of his right hand, and keeping his eyes on the engine tachometer, the helicopter assumed a nose high attitude while drifting backwards. The flight instructor was not able to recover the helicopter in time to avoid impact with the ground. The winds at the time of the accidents were reported from the south at 27 knots.
