Analysis

The private pilot was in cruise flight when the airplane experienced a partial loss of engine power. The carburetor heat was turned on and an increase in engine RPM was noticed, followed by a decrease in engine RPM. The pilot conducted a forced landing to the ocean adjacent to the beach. Examination of the engine assembly and accessories by an airframe and powerplant mechanic with inspection authority revealed no evidence of a precrash failure or malfunction. No determination could be made for the reported partial loss of engine power.
