Flight and Weather Advisory
During flight, the pilot obtained VFR flight following from Jacksonville Air Route Traffic Control Center (ARTCC) and was advised of adverse weather along the intended route. The pilot questioned the controller about a buildup that was 15–20 miles ahead. Radar data indicated that the airplane was heading 123 degrees with a ground speed of 125 knots. The controller suggested the pilot fly south for about 25 miles for weather avoidance.
Deviations and Turbulence
Over the next seven minutes, radar data showed the heading changed only 25 degrees, to a heading of 148 degrees. About two minutes before radar and radio contact were lost, the pilot advised the controller that the flight was experiencing turbulence.
Descent and Loss of Contact
At about 2035, the airplane entered a rapid descent from 9,200 feet to 1,100 feet mean sea level (MSL). Subsequently, radio and radar contact were lost. Wreckage from the airplane was located in the Gulf of Mexico near the location of the last radar contact.
Weather Conditions
Review of weather records indicated a rapidly developing thunderstorm in the area, rated VIP level 3 to level 5.
