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

THE PLT TOOK OFF ON A FLT TO YORK, PA TO REFUEL THE HELICOPTER & TO DEMONSTRATE IT TO A PROSPECTIVE BUYER WHILE EN ROUTE. WITNESSES OBSERVED THE HELICOPTER SHORTLY AFTER DEPARTURE. TWO OF 4 WITNESSES HEARD A CHANGE IN THE SOUND OF THE HELICOPTER, 2 WITNESSES SAW THE HELICOPTER SWINGING FROM SIDE TO SIDE PRIOR TO CRASHING, AND 2 OR THE WITNESSES SAW THE MAIN ROTOR ASSEMBLY SEPARATE FROM THE MAIN ROTOR DRIVE SHAFT. ONE WITNESS, WHO SAW THE HELICOPTER FLYING TOWARD HIS POSITION, REPORTED THAT IT STARTED TO 'SWOOP' DOWN, THEN TURNED UPWARD, AND THEN THE MAIN ROTOR ASSEMBLY & 2 OTHER PIECES SEPARATED. THE HELICOPTER THEN TURNED OVER & CRASHED. THE 1ST PERSON TO ARRIVE AT THE CRASH SITE SAID THE PLT DID NOT HAVE A SEAT BELT ON. AN EXAM OF THE WRECKAGE REVEALED THAT THE MAIN ROTOR MAST HAD SEPARATED ADJACENT TO THE MAIN ROTOR SYS STATIC STOPS. ALL FUSELAGE & FLT CONTROL SEPARATIONS WERE EXAMINED & FOUND TYPICAL OF OVERLOAD FAILURES. THE TAIL CONE HAD BEEN SEVERED BY THE MAIN ROTOR.
