Continental Express Flight 2574:
Continental Express Flight 2574 was a scheduled domestic passenger airline flight operated by Britt Airways [1] from Laredo International Airport in Laredo, Texas to Bush Intercontinental Airport in Houston, Texas. On September 11, 1991, the Embraer EMB 120 Brasilia, registered N33701, crashed as it was approaching the runway for landing, killing all 14 people on board. The aircraft wreckage hit an area near Eagle Lake, Texas.
[edit] Investigation
The National Transportation Safety Board (NTSB) investigation revealed that bolts had been removed from the horizontal stabilizer during maintenance the night before the accident and, following a shift change, the screws were not replaced. The plane crashed on its second flight of the day.
NTSB cited the failure of airline maintenance and inspection personnel to adhere to proper maintenance and quality assurance procedures. The failure of Federal Aviation Administration (FAA) surveillance to detect and verify compliance with approved procedures was cited as a contributing factor. Following the accident, the FAA conducted a National Aviation Safety Inspection Program (NASIP) of Continental Express' maintenance program. It found very few safety deficiencies, and complimented the airline on its internal evaluation system. NTSB expressed concern that the NASIP did not find deficiencies in shift turnover procedures and other matters relevant to the accident, and recommended that the agency improve its NASIP procedures.
[edit] Probable cause
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
"The failure of Continental Express maintenance and inspection personnel to adhere to proper maintenance and quality assurance procedures for the airplane's horizontal stabilizer device boots that led to the sudden in-flight loss of the partially secured left horizontal stabilizer leading edge and the immediate severe nose-down pitchover and breakup of the airplane. Contributing to the cause of the accident was the failure of the Continental Express management to ensure compliance with the approved maintenance procedures, and the failure of FAA surveillance to detect and verify compliance with approved procedures."
[edit] Role in developing the culture of safety
According to Meshkati (1997), the crash of Continental Express Flight 2574 was the most dramatic turning point for “safety culture” in the United States.[1] As a member of the National Transportation Safety Board (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” (NTSB/AAR-92/04, 1992, pg. 54, as cited in Meshkati, 1997). 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.
Continental still uses Flight 2574 on its Houston-Fayetteville-Newark route, and it continues to fly under Continental Express banner operated by ExpressJet Airlines.
