The NTSB's narrative final · quoted from the NTSB record
During cruise flight the pilot experienced an increase in engine noise before the engine suddenly lost power. While the fuel status and tank indications were normal, he attempted to restart the engine three separate times without success. The pilot reported to air traffic control that the engine had failed and that he would be conducting an emergency landing into the Gulf of Mexico. The pilot and passengers were able to egress the airplane and held onto a crab pot buoy. The occupants of the airplane were rescued by the United States Coast Guard the next morning. After impact, the airplane sank and was not located.
