Accident Overview
A general aviation aircraft was cruising at 10,000 feet MSL when the pilot observed a loss of manifold pressure. The pilot initiated a descent to 5,000 feet, where the outside air temperature was 38 degrees Fahrenheit. Despite the descent, manifold pressure did not exceed 20 inches of mercury. Shortly thereafter, the engine ceased producing power, necessitating a ditching maneuver.
Ditching and Rescue
The pilot ditched the aircraft in Prince William Sound near Naked Island. A nearby boat crew rescued the pilot and passenger from the water. Both individuals received treatment for hypothermia following the incident.
Aftermath
The aircraft sank in deep water and was not recovered. No further details regarding the aircraft type, registration, or operator were provided in the source material.
