The National Transportation Safety Board determines that the probable cause of this accident was the pilot’s inadequate airspeed management due to workload and degraded situation awareness and his improper inputs leading up to and during the aerodynamic stall, which increased the airplane’s angle of attack. Also causal was operation of the airplane above maximum gross weight, which reduced the airplane’s stall margin. Contributing to the accident were the operator’s inadequate safety management, which allowed the routine operation of flights that exceeded weight limitations, and the Federal Aviation Administration’s inadequate oversight of the operator, which failed to identify and address the routine operation of overweight flights.
