 As a member of the NTSB at that time, Dr. John Lauber suggested that the probable cause of this accident included "The failure of Continental Express management to establish a corporate culture which encouraged and enforced adherence to approved maintenance and quality assurance procedures".As a result of this and other similar aviation accidents, safety culture came to the forefront as the exclusive topic at the U.S. National Summit on Transportation Safety, hosted by the NTSB in 1997.This movement for air safety continued with the enactment on April 5, 2000, of the Wendell H. Ford Aviation Investment and Reform Act for the 21st Century, which is also called AIR 21.
