## Analysis

A CESSNA 310R DITCHED IN THE PACIFIC OCEAN APRX 500 NM SW HAWAII AFTER AN ENG FAILURE. THE PLT INDICATED THAT THE #2 ENG FAILED WHILE IN CRUISE FLT AT 8,000 FT MSL. OIL WAS OBSERVED LEAKING FROM THE ENG COWLING. THE ACFT WAS UNABLE TO MAINTAIN ALT ON #1 ENG. THE PLT REVERSED COURSE AND ATTEMPTED TO DUMP FUEL IN HOPE OF IMPROVING THE AIRPLANE'S SINGLE ENG PERFORMANCE. THE ACFT WAS EQUIPPED WITH A TEMPORARY LONG RANGE FUEL SYSTEM INSTALLED IN THE FUSELAGE AND WAS BEING FLOWN IN EXCESS OF ITS MAXIMUM CERTIFICATED GROSS WEIGHT. THE FERRY TANK FUEL WAS DRAINED INTO THE ACFT'S FUSELAGE. THE PLT STATED THAT HE HOPED THE FUEL WOULD FLOW OUT HOLES IN THE ACFT FUSELAGE. HE REPORTED THAT THE FUEL WAS FLOWING AROUND HIS FEET. THE ACFT WAS UNABLE TO MAINTAIN ALT AND WAS DITCHED IN THE OCEAN ARPX 45 MINUTES LATER. RECORDS INDICATE THE ACFT WAS SERVICED WITH 375.5 GALS OF FUEL THE EVENING PRIOR TO THE FLIGHT.
