Colgan Air Flight 3407 crashes into a house in Clarence Center, New York while on approach to Buffalo Niagara International Airport, killing all on board and one on the ground.
Colgan Air Flight 3407, operating as Continental Connection Flight 3407 under a codeshare agreement, was a scheduled passenger service that tragically crashed on Thursday, February 12, 2009. The flight originated from Newark Liberty International Airport (EWR) in Newark, New Jersey, and was destined for Buffalo Niagara International Airport (BUF) in Buffalo, New York. This devastating accident resulted in significant reforms for regional airline operations and pilot qualification standards across the United States.
The Tragic Event: Colgan Air Flight 3407
On that fateful evening, the Bombardier Q400 turboprop aircraft, carrying 49 passengers and crew, approached Buffalo. At approximately 10:17 pm EST (03:17 UTC on February 13), the aircraft experienced an aerodynamic stall, a critical condition where the wings can no longer generate sufficient lift. Despite the pilots' attempts, the aircraft did not recover from the stall and subsequently crashed into a residential house in Clarence Center, New York, a suburb of Buffalo.
The impact claimed the lives of all 49 individuals on board, including 45 passengers and 4 crew members. Tragically, one person inside the house also perished, bringing the total fatalities to 50. The destruction was extensive, with the aircraft and house completely engulfed in flames.
- What is a codeshare agreement in aviation?
- A codeshare agreement allows one airline to market and sell flights operated by another airline under its own flight number. In this case, Colgan Air operated Flight 3407, but it was marketed and sold as a Continental Connection flight, providing broader network access for passengers and airlines alike. Passengers booked through Continental Connection expected the same safety standards and service, regardless of the operating carrier.
The Bombardier Q400 Aircraft
The aircraft involved, a Bombardier Q400 (De Havilland Canada DHC-8-400), is a twin-engine, medium-range turboprop airliner designed for short-haul regional flights. Known for its speed and efficiency compared to other turboprops, it typically carries between 68 and 90 passengers. Its robust design and operational history made the nature of this accident particularly alarming to the aviation community.
Investigation and Probable Cause by the NTSB
The National Transportation Safety Board (NTSB), the independent U.S. government agency responsible for civil aviation accident investigations, promptly initiated a thorough inquiry into Flight 3407. After a comprehensive investigation, the NTSB published its final report on Tuesday, February 2, 2010. The report meticulously detailed the sequence of events and identified the probable cause of the crash.
Key Findings and Contributing Factors
The NTSB concluded that the probable cause of the accident was the pilots' inappropriate response to the stick shaker and stick pusher stall warnings. Specifically, the Captain's actions contradicted standard stall recovery procedures by pulling back on the control yoke, which further aggravated the stall condition, instead of pushing forward to increase airspeed and regain lift.
Several critical contributing factors were also identified:
- Pilot Fatigue: The Captain, Marvin Renslow, and First Officer, Rebecca Lynne Shaw, were found to have been experiencing significant fatigue, which impaired their performance. The Captain, in particular, had commuted long distances overnight to reach Newark for his shift.
- Inadequate Pilot Training: Colgan Air's training programs, especially regarding stall recognition and recovery, were found to be insufficient. Pilots also demonstrated poor airmanship and judgment during simulator check rides.
- Inadequate Airspeed Monitoring: The pilots failed to maintain appropriate airspeed, allowing the aircraft to slow to a dangerously low speed for its configuration.
- First Officer's Role: The First Officer did not effectively monitor the flight instruments or challenge the Captain's inappropriate control inputs, which is a critical aspect of crew resource management (CRM).
- Sterile Cockpit Violations: Discussions unrelated to flight operations during critical phases of flight further compromised the crew's focus.
- Insufficient FAA Oversight: The Federal Aviation Administration (FAA) was found to have provided insufficient oversight of Colgan Air's training and fatigue management programs.
- What is an aerodynamic stall and why is it dangerous?
- An aerodynamic stall occurs when the angle of attack (the angle between the wing and the oncoming air) becomes too great, causing the airflow over the wings to separate and dramatically reduce lift. This can lead to a rapid loss of altitude and control. Modern aircraft are equipped with stall warning systems, such as stick shakers and stick pushers, designed to alert pilots and, in some cases, automatically initiate recovery actions. Proper recovery typically involves reducing the angle of attack and increasing engine thrust.
Lasting Impact: Regulatory Reforms and Pilot Safety
Colgan Air Flight 3407 stands as the most recent aviation incident involving a U.S.-based airline that resulted in multiple fatalities to date, excluding general aviation or military incidents. The tragedy profoundly impacted the families of the victims, who became powerful advocates for aviation safety reform.
The Airline Safety and Federal Aviation Administrative Extension Act of 2010
Through persistent lobbying efforts by the families, the U.S. Congress enacted the Airline Safety and Federal Aviation Administrative Extension Act of 2010 (Public Law 111–216). This landmark legislation significantly enhanced regulations for regional carriers and pilot qualifications, directly addressing many of the NTSB's findings from the Flight 3407 investigation.
Key provisions of the Act included:
- Increased First Officer Flight Hour Requirements: The minimum flight hours required for a first officer to qualify for an airline transport pilot (ATP) certificate was raised from 250 hours to 1,500 hours, matching the requirements for captains. This "1,500-hour rule" aimed to ensure that all airline pilots possess a higher level of experience.
- Enhanced Pilot Fatigue Rules: New, more stringent rules were mandated regarding pilot rest periods and duty limitations to combat fatigue effectively.
- Mandatory Airline Transport Pilot (ATP) Certificate: All airline pilots were required to hold an ATP certificate, a higher standard of pilot certification, before flying for an airline.
- Improved Training Standards: The Act mandated improvements in airline pilot training programs, particularly focusing on stall prevention and recovery, upset recovery, and adherence to sterile cockpit procedures.
- Better Record Keeping: Airlines were required to maintain better pilot records to track performance and training histories more effectively.
The Colgan Air Flight 3407 disaster served as a pivotal moment in aviation history, leading to sweeping changes that have fundamentally reshaped regional airline operations and significantly improved pilot training and fatigue management, ultimately enhancing air safety for passengers in the United States.
