NTSB Narrative Summary Released at Completion of Accident

The pilot stated that while returning to the airport during cruise flight, 'the engine suddenly started shaking violently....Then smoke started coming out of the front of the engine compartment. Suddenly the engine and [propeller] stopped cold. I realized that we could not make it to the runway and we then quickly decided to head for the water.' Examination of the engine revealed a 1 inch hole in the crankcase in the vicinity of the #2 cylinder, and the #1 connecting rod bolt had separated. The bolt was not located for further examination.

NTSB Probable Cause Narrative

separation of the number one connecting rod bolt, which resulted in a total loss of engine power.
