THE PILOT DEPARTED FROM THE ROAD ADJACENT TO THE POTATO FIELD HE HAD BEEN SPRAYING AND WAS GOING TO REPOSITION FOR ANOTHER SPRAYING RUN. WHILE THE HELICOPTER WAS MAKING A RIGHT TURN, IT ROLLED TO THE RIGHT AND CRASHED INTO THE BRUSH AND TREES SOUTH OF THE RIVER. THE PILOT'S SON STATED THERE WAS NO INDICATION OF A MECHANICAL PROBLEM PRIOR TO THE ACCIDENT. NO ANOMALIES WERE DISCOVERED DURING ENGINE TEARDOWN. HOWEVER, THE CYCLIC STICK CONTROLS FOR THE RIGHT SEAT, THE SEAT THE PILOT WAS FLYING FROM, WERE DIFFERENT THAN THOSE FOR THE LEFT SEAT. THE RIGHT STICK WAS SIGNIFICANTLY FURTHER BACK AND TO THE LEFT THAN THE LEFT CONTROLS. IN FACT, THE SON SAID TO A WITNESS THAT '...IN ORDER TO FLY THE HELICOPTER LEVEL, HE (THE PILOT) HAD TO HAVE THE CYCLIC ALMOST FULL LEFT.'
Probable Cause: WAS THE PILOT IN COMMAND'S FAILURE TO MAINTAIN AIRCRAFT CONTROL. A FACTOR TO THE ACCIDENT WAS THE INADEQUATE CYCLIC CONTROL.
