NTSB Narrative Summary Released at Completion of Accident

ACFT EXPERIENCED A POWER LOSS IMMEDIATELY AFTER TAKEOFF FROM AN OFFSHORE PLATFORM IN THE GULF OF MEXICO. THE PLT HELD COLLECTIVE TO CLEAR THE RIG AND THEN POPPED THE FLOATS AND AUTOROTATED TO THE WATER. THE AUTO WAS SUCCESSFUL, HOWEVER, THE ACFT WAS STRUCK BY A 5' WAVE AND ROLLED OVER. BOTH OCCUPANTS EGRESSED WITHOUT PROBLEM AND THE PAX SWAM TO THE RIG. THE PLT INFLATED HIS LIFE VEST AND WAS SWEPT AWAY BY THE CURRENT AND SWAM ASHORE 14 HOURS LATER. INVESTIGATION REVEALED THAT THE COMPRESSOR DISCHARGE PRESSURE (PC) LINE WAS DISCONNECTED FROM THE BACK OF THE ENG FUEL CONTROL. A LEAK OR SEPARATION OF THE PC LINE WOULD CAUSE THE FUEL SCHEDULE TO REDUCE ENG SPEED TO BELOW FLT IDLE. NO RECENT MAINTENANCE HAD BEEN PERFORMED ON THE FUEL CONTROL OR THE LINE.
