What happened
During a maritime supply operation conducted for the Central Intelligence Agency, an aircraft crashed into the ocean a short distance from Hua Hin. The mission was being performed at a low altitude when the pilot-in-command initiated a left-hand turn. During this maneuver, the left wing made contact with the water's surface, leading to the immediate destruction of the aircraft.
There were seven fatalities recorded in the accident, with no survivors among the crew members on board.
Findings
Investigations into the crash determined that the incident was caused by a misjudgment of altitude relative to the sea surface. The flight crew failed to correctly evaluate their distance from the water during the low-level turn, which directly led to the wing strike and subsequent impact.
