NTSB/AAR-07/01. Washington, DC.
Abstract: This report explains the accident involving a Bombardier CL-600-2B19, N8396A, which
crashed into a residential area about 2.5 miles south of Jefferson City Memorial Airport, Jefferson
City, Missouri. During the flight, both engines flamed out after a pilot-induced aerodynamic stall
and were unable to be restarted. Safety issues discussed in this report focus on flight crew training
in the areas of high altitude climbs, stall recognition and recovery, and double engine failures;
flight crew professionalism; and the quality of some parameters recorded by flight data recorders
on regional jet airplanes.
The National Transportation Safety Board is an independent Federal agency dedicated to promoting aviation, railroad, highway, marine,
pipeline, and hazardous materials safety. Established in 1967, the agency is mandated by Congress through the Independent Safety Board
Act of 1974 to investigate transportation accidents, determine the probable causes of the accidents, issue safety recommendations, study
transportation safety issues, and evaluate the safety effectiveness of government agencies involved in transportation. The Safety Board
makes public its actions and decisions through accident reports, safety studies, special investigation reports, safety recommendations, and
statistical reviews.
