At about 1830 Eastern time, the airplane was substantially damaged during a forced landing into a lake following a loss of engine power. The private pilot was not injured. Visual conditions prevailed. During a downwind-to-base turn, at about 500 feet agl, the pilot began the final checklist for landing and activated the fuel pump. Immediately after the fuel pump activated, the Lycoming TIO-540 engine began to “sputter” and lose power. The pilot turned off the fuel pump and performed emergency procedures to restart the engine, which were unsuccessful. He elected to land in the lake after attempting to restart the engine several times.
