## Analysis

THE PLT STATED THAT JUST AFTER PASSING LAKELAND, FL, HIS ENG RPM BEGAN TO FLUCTUATE. HE SELECTED HIS AUX FUEL TANKS BUT THE RPM CONTINUED TO DETERIORATE. HE ELECTED TO MAKE HIS FORCED LANDING ON A SMALL LAKE BUT NOT HAVING ENOUGH ALT TO TURN & LAND INTO THE WIND, LANDED DOWNWIND. UPON TOUCHDOWN THE ACFT FLIPPED OVER & SANK IN APRX 14 FT OF WATER. THE ENG WAS PLACED IN A TEST STAND & IT RAN WITH NO DISCREPANCIES NOTED. DUE TO THE ACFT BEING IMMERSED IN WATER THE POSSIBILITY OF WATER IN THE FUEL OR FUEL CONTAMINATION COULD NOT BE DETERMINED. THEREFORE THE NATURE OF THE ENG MALFUNCTION COULD NOT BE DETERMINED AS DESCRIBED BY THE PLT.
