The helicopter substantially damaged following a loss of control after landing due to ground resonance. The two certified flight instructors were not injured.
In a telephone conversation with the National Transportation Safety Board investigator-in-charge, the flight instructor who was acting as pilot-in-command reported that after landing and in the process of bottoming out the collective, the helicopter began to gently oscillate fore and aft about its longitudinal axis. This was followed shortly by the oscillating condition becoming more severe, to the point where one main rotor blade, the tail boom, and the lower vertical fin impacted terrain. The tail boom and lower vertical fin were substantially damaged as the result of the impact with terrain.
