DURING CRUISE FLT, THE PLT REPORTED THAT THE RT ENG COWLING PARTIALLY SEPARATED & THE LT FWD CYLINDER OF THAT ENG SEPARATED, FOLLOWED BY AN ENG COMPARTMENT FIRE. HE ATTEMPTED TO FEATHER THE PROPELLER BUT WAS UNABLE. HE INITIATED A DESCENT TO EXTINGUISH THE FIRE & WAS SUCCESSFUL BUT AFTER LEVELING OFF, WAS UNABLE TO MAINTAIN DIRECTIONAL CONTROL. HE DITCHED THE AIRPLANE & BOTH HE & THE PAX EXITED THE ACFT. THE PLT DRAGGED THE SERIOUSLY INJURED PAX WITH HIM TO A NEARBY ISLAND WHERE THEY WERE RESCUED THE FOLLOWING DAY.
