NTSB Narrative Summary Released at Completion of Accident

THE NEWLY PURCHASED HELICOPTER WAS TRANSPORTED TO SAIPAN BY SHIP IN A CONTAINER. AFTER UNLOADING, THE PILOT, A MECHANIC AND A MECHANIC'S HELPER REASSEMBLED IT ON THE DOCK. THE HELPER WAS SENT TO BUY SOME FUEL FOR THE HELICOPTER, SO IT COULD BE FLOWN FROM THE DOCK TO THE COMPANY BASE AT THE AIRPORT. THE COMPANY HAD BEEN OPERATING TURBINE POWERED HELICOPTERS ONLY; THIS WAS ITS FIRST PISTON POWERED MODEL. THE HELPER WENT TO THE FUEL FACILITY AND BOUGHT 10 GALLONS OF JET-A FUEL, WHICH HE USED TO SERVICE THE HELICOPTER. THE PILOT STARTED THE HELICOPTER, DID A RUN-UP AND TOOK OFF FOR A 3 MILE FLIGHT TO THE AIRPORT. HOWEVER, THE ENGINE LOST POWER AND THE PILOT MADE AN AUTOROTATION TO A SUBMERGED REEF IN ABOUT 3 TO 4 FEET OF WATER.

NTSB Probable Cause Narrative

FAILURE OF MAINTENANCE PERSONNEL TO ASSURE THE HELICOPTER WAS SERVICED WITH THE PROPER GRADE OF FUEL. A FACTOR REALATED TO THE ACCIDENT WAS: THE LACK OF A SUITABLE LANDING AREA, WHICH RESULTED IN HAVING TO DITCH THE HELICOPTER IN THE WATER.
