NTSB Narrative Summary Released at Completion of Accident

THE STUDENT PILOT WAS RECEIVING INSTRUCTION IN THE BELL 47 HELICOPTER FROM A CERTIFIED FLIGHT INSTRUCTOR (CFI). AFTER A 1.5 HOUR DUAL INSTRUCTION FLIGHT, THE STUDENT AND THE CFI RETURNED TO THE DEPARTURE AIRPORT TO REFUEL, AND WERE PLANNING TO DEPART AGAIN FOR ANOTHER TRAINING FLIGHT. AFTER LANDING, THE HELICOPTER WAS LEFT IDLING WITH THE RSP AT THE CONTROLS WHILE THE CFI EXITED THE HELICOPTER TO RETRIEVE THE FUEL TRUCK. THE CFI RETURNED WITH THE FUEL TRUCK, RE-FUELED THE HELICOPTER AND WAS RETURNING THE FUEL HOSE TO THE TRUCK WHEN THE TURNING ROTOR BLADES STRUCK THE HOSE AND FUEL TRUCK. THE HOSE IN TURN STRUCK THE CFI. THE INVESTIGATION REVEALED THAT THE TRUCK HAD BEEN PARKED ABOUT 3.5 FEET FROM THE TURNING ROTOR BLADES, AND COMPANY POLICY MANDATED A MINIMUM OF A 10 FOOT CLEARANCE. RE-ENACTMENT OF THE HOSE STOWAGE TO THE SIDE OF THE FUEL TRUCK SHOWED A TENDENCY FOR THE HOSE TO DEFLECT UP INTO THE ROTOR TIP PATH PLANE.

NTSB Probable Cause Narrative

The pilot's failure to maintain adequate clearance of the fuel truck from the aircraft, which resulted in the main rotor striking the fuel hose and truck during refueling operation. A factor was the pilot's failure to follow company policy pertaining to the refueling of aircraft.
