Probable cause
A total loss of engine power for undetermined reasons.
NTSB analysis
About 2 hours into a cross-country flight over water, the pilot heard a noticeable change in engine noise and observed erratic engine torque readings. Moments later the airplane experienced a complete loss of engine power. After declaring an emergency, the pilot attempted to diagnose the problem and restart the engine to no avail. The airplane ditched 175 miles from land, in water over 5,000 feet deep. The airplane was not recovered and the reason for the loss of engine power could not be determined.
