NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

THE HELICOPTER ARRIVED AT THE NEWARK INTL ARPT AT 1531 AFTER AN UNEVENTFUL FLT FROM NEW YORK, NY WITH 2 EN ROUTE STOPS. AT 1540, THE PLT TAXIED FROM THE PASSENGER GATE FOR DEPARTURE. ACCORDING TO HIM, HE HAD NO CONTROL PROBLEMS, WHILE TAXIING. HE CHECKED THE ANNUNCIATOR PANEL BEFORE STARTING HIS TAKEOFF & SAW NO WARNING LIGHTS. COLLECTIVE PITCH WAS INCREASED TO REDUCE WEIGHT ON THE GEAR, FOLLOWED BY FURTHER PITCH INCREASE TO OBTAIN A HOVER. AT THAT TIME, THE CYCLIC CONTROL MOVED ABRUPTLY TO THE LEFT & WAS ACCOMPANIED WITH THE RIGHT MAIN GEAR BECOMING AIRBORNE. THE PLT APPLIED RIGHT CYCLIC & DECREASED THE COLLECTIVE; HOWEVER, THE HELICOPTER CONTINUED TO ROLL LEFT. THE HELICOPTER THEN HOPPED ON THE LEFT MAIN GEAR 3 TIMES & THE MAIN ROTOR BLADES HIT THE PAVEMENT. SUBSEQUENTLY, THE ACFT CAME TO REST ON ITS LEFT SIDE. AN EXAM & FUNCTIONAL TEST OF THE FLT CONTROL HYDRAULIC SYSTEMS REVEALED NO REASON FOR THE MALFUNCTION.THE TEMP WAS BELOW FREEZING (29 DEG), BUT NO SYSTEM ICING WAS FOUND.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
