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

The pilot stated that while manuevering, the low rotor rpm warning came on so he lowered to collective to regain rotor rpm and maintain altitude. He stated that suddenly there was a "huge vibration," no warnings on the instrument panel, and the vibration seemed to worsen. He noticed that the engine and rotor rpms were well above the "red zone." The pilot immediately closed the throttle and the rpm began to decrease. He then selected a field and made an autorotative landing to an uneven field. The tailboom separated during the landing. Post accident examination of the helicopter and its systems revealed no anomalies. The the engine was test run, and no evidence of precrash anomalies were noted.
