Accident Summary:

 AT APPROXIMATELY 1830 HOURS, COBRA 38 LEFT VINH LONG, DESTINATION YRBM-20, LOCATED IN THE RIVER NEAR CHAU DUC. ITS CREW CONSISTED OF 1LT MCGILL AS PILOT AND WO1 EDGE AS CO-PILOT. THE AIRCRAFT ARRIVED AT YRBM'S LOCATION AT APPROXIMATELY 1900 HOURS AND CIRCLED UNTIL ITS FUEL LEVEL WAS BELOW 1000 LBS. LT JG THOMAS BERRY, THE COMMAND DUTY OFFICER, THEN GAVE COBRA 38 A GREEN DECK FOR LANDING WHICH MEANT THE YRBM HAD BEEN MANEUVERED INTO A POSITION WHICH GAVE COBRA 38 A 10 TO 15 KNOT HEADWIND FOR LANDING. COBRA 38 MADE WHAT APPEARED TO BA A NORMAL APPROACH. THE FRONT PORTION OF THE AIRCRAFT WASSPSITIONED OVER THE FLIGHT DECK AND THE PILOT WAS ADDING THE REQUIRED POWER FOR LANDING WHEN THE ENGINE RPM SUDDENLY STARTED DECREASING. THE PILOT BROUGHT THE AIRCRAFT TO A MOMENTARY HOVER IN HOPES OF REGAINING RPM, BUT THE RPM WAS SO LOW THAT HE RAN OUT OF DIRECTIONAL PEDAL CONTROL. THE AIRCRAFT MADE A 360 DEGREE TURN OVER THE FLIGHT DECK. UPON COMPLETION OF THE TURN, THE PILOT REASONED IT WOULD BE SAFER TO REMOVE THE AIRCRAFT FROM ABOVE THE FLIGHT DECK AND REGAIN RPM OVER THE WATER. ALSO, THE DANGER OF A CRASH WOULD BE LESS HAZARDOUS OVER WATER THAN ON THE FLIGHT DECK. THE PILOT THEN APPLIED RIGHT CYCLIC, CAUSING THE AIRCRAFT TO MOVE OFF THE FLIGHT DECK SIDEWAYS, THEN INTO A FORWARD DIVE. THE AIRCRAFT STARTED SPINNING AND COMPLETED TWO 360 DEGREE TURNS OVER THE WATER, CONTINUING TO LOSE RPM. THE AIRCRAFT THEN HIT THE WATER, RIGHT SKID FIRST. AS THE SKID HIT THE WATER, THE PILOT ROLLED OFF THE THROTTLE AND APPLIED RIGHT CYCLIC CAUSING THE MAIN ROTOR BLADE TO STRIKE THE WATER AND STOP. THE AIRCRAFT THEN SANK ONTO ITS RIGHT SIDE, AND THE CO-PILOT EXITED THE AIRCRAFT. THE PILOT TRIED PULLING HIS EMERGENCY EXIT HANDLE, BUT THE CANOPY WOULD NOT BREAK AWAY. THE CO-PILOT NOTICING THIS, RETURNED TO HIS SEAT, REMOVED HIS BREAKOUT KNIFE, AND CUT OUT THE PLEXIGLAS ON THE AIRCRAFT'S LEFT SIDE. THE CO-PILOT HELPED THE PILOT OUT OF HIS COCKPIT AND THEY WERE PICKED UP BY A NAVY RESCUE BOAT. THE AIRCRAFT THEN SUBMERGED.\\
