## Analysis

THE PLT RPRTD THAT AFTER ABOUT 10 HRS ON AN OVERWATER FERRY FLT, HE NOTICED HIGH OIL TEMP & LOW OIL PRESSURE INDCNS FROMTHE REAR ENG. EVENTUALLY THE REAR ENG BEGAN RUNNING ROUGH, SO HE SHUT IT DOWN, FEATHERED ITS PROP AND 'INCREASED POWER ON THE FRONT ENGINE'. ABOUT 1 HR LATER, THE FRONT ENG BEGAN INDICATING A HIGH CYLINDER HEAD TEMP (CHT). HE REDUCED POWER (SOMEWHAT) ON THE FRONT ENG & RESTARTED THE REAR ENG. HOWEVER, AFTER ABOUT 10 MIN, THE REAR ENG BEGAN RUNNING SO ROUGH, HE SHUT DOWN & SECURED IT AGAIN. SUBSEQUENTLY, WHILE TALKING TO A COAST GUARD C-130 & GIVING A POSITION RPRT, THE FRONT ENG LOST POWER COMPLETELY. THE PLT REPORTED THERE WAS SUFFICIENT FUEL ABOARD AND THE FRONT ENG WAS RUNNING ON THE MN TANK. THE PLT ATMTD A RESTART, BUT WAS UNABLE TO GET EITHER ENG TO RUN. HE DITCHED THE ACFT IN THE OCEAN & WAS EVENTUALLY RESCUED. THE ACFT WAS NOT RECOVERED.
