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

THE PILOT SAID THE HELICOPTER HAD JUST LEVELED OFF IN CRUISE WHEN IT MADE AN UNCOMMANDED LEFT YAW ACCOMPANIED BY AN ENGINE OVERSPEED. THE PILOT ENTERED AN AUTOROTATION, DIAGNOSING THE PROBLEM AS A LOSS OF POWER THROUGH THE DRIVE TRAIN. DURING THE AUTOROTATION, HE ATTEMPTED TO 'REJOIN' THE NEEDLES, BUT WAS ONLY SUCCESSFUL IN INCREASING ENGINE RPM. AS HE APPROACHED HIS PLANNED TOUCHDOWN POINT, HE TURNED ON THE LANDING LIGHT WHICH ILLUMINATED UTILITY WIRES THAT HE HAD NOT SEEN PREVIOUSLY. HE MADE A CYCLIC CLIMB OVER THE WIRES, BUT DID NOT HAVE SUFFICIENT AIRSPEED, ALTITUDE, OR MAIN ROTOR RPM REMAINING TO CUSHION THE TOUCHDOWN. SUBSEQUENT POSTACCIDENT TEARDOWNS AND INSPECTIONS REVEALED NO MECHANICAL ABNORMALITIES.
