Colgan Air Flight 3407, marketed as Continental Connection under a codeshare agreement with Continental Airlines, was a scheduled passenger flight from Newark, New Jersey, to Buffalo, New York, which crashed on February 12, 2009. The aircraft, a De Havilland Canada Dash-8 Q400, entered an aerodynamic stall from which it did not recover and crashed into a house in Clarence Center, New York at 10:17 p.m. EST (03:17 UTC), killing all 49 passengers and crew on board, as well as one person inside the house.
Continental Connection was a brand name under which several commuter airline carriers and their holding companies operated services marketed exclusively by Continental Airlines. As such, all Continental Connection banner carrier services were operated primarily with turboprop aircraft in contrast to Continental Express, whose flights were operated by Continental's regional jet partners, ExpressJet Airlines and Chautauqua Airlines. Continental Connection operations were merged into Continental Express in 2012.
A codeshare agreement, also known as codeshare, is a business arrangement, common in the aviation industry, in which two or more airlines publish and market the same flight under their own airline designator and flight number as part of their published timetable or schedule. Typically, a flight is operated by one airline while seats are sold for the flight by all cooperating airlines using their own designator and flight number.
Continental Airlines was a major United States airline founded in 1934 and eventually headquartered in Houston, Texas. It had ownership interests and brand partnerships with several carriers.
The National Transportation Safety Board conducted the accident investigation and published a final report on February 2, 2010, which found the probable cause to be the pilots' inappropriate response to the stall warnings.As of 2019, Flight 3407 is the most recent aviation incident resulting in mass casualties involving a U.S.-based airline.
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, and railroad accidents. When requested, the NTSB will assist the military and foreign governments with accident investigation. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. As of December 2014, it has four regional offices located in Anchorage, Alaska; Denver, Colorado; Ashburn, Virginia; and Seattle, Washington. The agency also operates a national training center at its Ashburn facility.
Families of the accident victims lobbied the U.S. Congress to enact more stringent regulations for regional carriers, and to improve the scrutiny of safe operating procedures and the working conditions of pilots. Although it did nothing to address the specific causes of the crash –improper stall recovery technique and pilot fatigue –the Airline Safety and Federal Aviation Administrative Extension Act of 2010 (Public Law 111-216) required some of these regulation changes.
Colgan Air Flight 3407 (9L/CJC 3407) was marketed as Continental Connection Flight 3407. It was delayed two hours, departing at 9:18 p.m. Eastern Standard Time (EST; 02:18 UTC), en route from Newark Liberty International Airport to Buffalo Niagara International Airport.

Newark Liberty International Airport, originally Newark Metropolitan Airport and later Newark International Airport, is one of the major airports of the Port Authority of New York and New Jersey and is located in the U.S. state of New Jersey. The airport straddles the boundary between the cities of Newark and Elizabeth, the former of which is the most populous city in the state. The airport is owned jointly by the cities of Elizabeth and Newark and leased to and operated by the Port Authority of New York and New Jersey.
The twin-engine turboprop Bombardier Dash 8 Q400, FAA registry N200WQ, was manufactured in 2008 for Colgan.
A turboprop engine is a turbine engine that drives an aircraft propeller.
This was the first fatal accident for a Colgan Air passenger flight since the company was founded in 1991. One previous ferry flight (no passengers) crashed offshore of Massachusetts in August 2003, killing both of the crew on board. The only prior accident involving a Colgan Air passenger flight occurred at LaGuardia Airport, when another plane collided with the Colgan aircraft while taxiing, resulting in minor injuries to a flight attendant.
Colgan Air Flight 9446 was a repositioning flight operated by Colgan Air for US Airways Express. On August 26, 2003 a Beech 1900D crashed into water 100 yards offshore from Yarmouth, Massachusetts, United States shortly after taking off from Barnstable Municipal Airport in Yarmouth. Both pilots were killed.
LaGuardia Airport is an airport in the northern part of the New York City borough of Queens in the United States. It is on the waterfront of Flushing and Bowery Bays in East Elmhurst and borders the neighborhoods of Astoria and Jackson Heights. The airport is the third busiest airport serving New York City, and the twentieth busiest in the United States. LaGuardia Airport covers 680 acres (280 ha).
Captain Marvin Renslow, 47, of Lutz, Florida, was the pilot in command, and Rebecca Lynne Shaw, 24, of Maple Valley, Washington, served as the first officer.There were two flight attendants: Matilda Quintero and Donna Prisco. Captain Renslow was hired in September 2005 and had accumulated 3,379 total flight hours, with 111 hours as captain on the Q400. First Officer Shaw was hired in January 2008, and had 2,244 hours, 774 of them in turbine aircraft including the Q400.
There were two Canadian passengers, one Chinese passenger, and one Israeli passenger on board. The remaining 41 passengers, as well as the crew members, were American.
Shortly after the flight was cleared for the runway 23 instrument landing system approach to Buffalo Niagara International Airport, it disappeared from radar. The weather consisted of light snow and fog with wind of 15 knots (28 km/h; 17 mph). The de-icing system had been turned on 11 minutes after takeoff. Shortly before the crash, the pilots discussed significant ice buildup on the aircraft's wings and windshield. Two other aircraft reported icing conditions around the time of the crash.
The last radio transmission from the flight occurred when the first officer acknowledged a routine instruction to change to tower radio frequency. The plane was 3.0 miles (4.8 km) northeast of the radio beacon KLUMP (see diagram) at that time. The crash occurred 41 seconds after that last transmission. Since ATC approach control was unable to get any further response from the flight, the assistance of Delta Air Lines Flight 1998 and US Airways Flight 1452 was requested. Neither was able to spot the missing plane.
Following the clearance for final approach, landing gear and flaps (5 degrees) were extended. The flight data recorder (FDR) indicated the airspeed had slowed to 145 knots (269 km/h). The captain then called for the flaps to be increased to 15 degrees. The airspeed continued to slow to 135 knots (250 km/h). Six seconds later, the aircraft's stick shaker activated, warning of an impending stall as the speed continued to slow to 131 knots (243 km/h). The captain responded by abruptly pulling back on the control column, followed by increasing thrust to 75% power, instead of lowering the nose and applying full power, which was the proper stall recovery technique. That improper action pitched the nose up even further, increasing both the g-load and the stall speed. The stick pusher activated ("The Q400 stick pusher applies an airplane-nose-down control column input to decrease the wing angle-of-attack [AOA] after an aerodynamic stall"), but the captain overrode the stick pusher and continued pulling back on the control column. The first officer retracted the flaps without consulting the captain, making recovery even more difficult.
In its final moments, the aircraft pitched up 31 degrees, then pitched down 25 degrees, then rolled left 46 degrees and snapped back to the right at 105 degrees. Occupants aboard experienced g-forces estimated at nearly 2 G's. The crew made no emergency declaration as they rapidly lost altitude and crashed into a private home at 6038 Long Street, 5 miles (8.0 km) from the end of the runway, with the nose pointed away from the airport. The aircraft burst into flames as the fuel tanks ruptured on impact, destroying the house of Douglas and Karen Wielinski, and most of the plane. Douglas was killed; his wife Karen and their daughter Jill managed to escape with minor injuries. There was very little damage to surrounding homes, even though the lots in that area are only 60 feet (18.3 meters) wide. The home was close to the Clarence Center Fire Company, so emergency personnel were able to respond quickly. Two of the firefighters were injured. Twelve nearby houses were evacuated.about
A total of 50 people died, including the 49 passengers and crew on board when the aircraft was destroyed, and one resident of the house that was struck. There were four injuries on the ground, including two other people inside the home at the time of the crash. Among the dead were:
The U.S. National Transportation Safety Board (NTSB) began their inquiry on February 13, with a team of 14 investigators.Both the flight data recorder (FDR) and the cockpit voice recorder (CVR) were recovered and analyzed in Washington, D.C.
Data extracted from the FDR revealed the aircraft went through severe pitch and roll oscillations shortly after the extension of flaps and landing gear, which was followed by the activation of the "stick shaker" stall warning system. The aircraft fell 800 feet (240 m) and then crashed on a northeast heading, opposite of the approach heading to the airport. Occupants experienced estimated accelerations of up to 2 g prior to impact.
Freezing temperatures made it difficult to access crash debris. Portable heaters were used to melt ice left in the wake of the firefighting efforts. Human remains were carefully removed, and then finally identified, over a period of several weeks. The cockpit had sustained the greatest impact force, while the main cabin was mostly destroyed by the ensuing fire. Passengers in the rear section were still strapped in their seats.
The autopilot was in control until it automatically disconnected when the stall warning stick shaker activated. The NTSB found no evidence of severe icing conditions, which would have required the pilots to fly manually.Colgan recommended its pilots to fly manually in icing conditions, and required them to do so in severe icing conditions. In December 2008, the NTSB issued a safety bulletin about the danger of keeping the autopilot engaged during icing conditions. Flying the plane manually was essential to ensure pilots would be able to detect changes in the handling characteristics of the airplane, which are a warning sign of ice accumulation.
After the captain reacted inappropriately to the stick shaker stall warning, the stick pusher activated. As designed, it pushed the nose down when it sensed a stall was imminent, but the captain again reacted improperly and overrode that additional safety device by pulling back again on the control column, causing the plane to stall and crash.Bill Voss, president of Flight Safety Foundation, told USA Today that it sounded like the plane was in "a deep stall situation".
On May 11, 2009, information was released about Captain Renslow's training record. According to an article in The Wall Street Journal , before joining Colgan he had failed three "check rides", including some at Gulfstream International's training program, and "people close to the investigation" suggested that he might not have been adequately trained to respond to the emergency that led to the airplane's fatal descent.Investigators examined possible crew fatigue. The captain appeared to have been at Newark airport overnight, prior to the day of the 9:18 pm departure of the accident flight. The first officer commuted from Seattle to Newark on an overnight flight. These findings during the investigation led the FAA to issue a "Call to Action" for improvements in the practices of regional carriers.
Another press report said that the pilot had failed five prior tests, and also alleged "flirtatious" conversation in the cockpit between the pilot and the much-younger First Officer.
In response to questioning from the NTSB, Colgan Air officials acknowledged both pilots apparently were not paying close attention to the aircraft's instruments and did not properly follow the airline's procedures for handling an impending stall. "I believe Capt. Renslow did have intentions of landing safely at Buffalo, as well as first officer Shaw, but obviously in those last few moments ... the flight instruments were not being monitored, and that's an indication of a lack of situational awareness," said John Barrett, Colgan's director of flight standards.
The official transcript of the crew's communication, obtained from the CVR, as well as an animated depiction of the crash, constructed using data from the FDR, were made available to the public on May 12, 2009. Some of the crew's communication violated federal rules banning nonessential conversation.
On June 3, 2009, The New York Times published an article detailing complaints about Colgan's operations from an FAA inspector who observed test flights in January 2008.As in a previous FAA incident handling other inspectors' complaints, the Colgan inspector's complaints were deferred and the inspector was demoted. The incident is under investigation by the Office of Special Counsel, the agency responsible for U.S. Government federal whistle-blower complaints.
On February 2, 2010, the NTSB issued its final report, describing the details of its investigation that led to 46 specific conclusions.
Among those conclusions were the fact that both the Captain and the first officer responded to the stall warning in a manner contrary to their training. The NTSB could not explain why the first officer retracted the flaps and suggested that the landing gear should also be retracted, though it did find that the current approach-stall training was not adequate:
The current air carrier approach-to-stall training did not fully prepare the flight crew for an unexpected stall in the Q400 and did not address the actions that are needed to recover from a fully developed stall.
Those findings were immediately followed by the Board's "Probable Cause" statement:
The captain's inappropriate response to the activation of the stick shaker, which led to an aerodynamic stall from which the airplane did not recover. Contributing to the accident were (1) the flight crew's failure to monitor airspeed in relation to the rising position of the low-speed cue, (2) the flight crew's failure to adhere to sterile cockpit procedures, (3) the captain's failure to effectively manage the flight, and (4) Colgan Air's inadequate procedures for airspeed selection and management during approaches in icing conditions. 155:
NTSB Chairman Deborah Hersman, while concurring, made it clear that she considered fatigue to be a contributing factor. She compared the twenty years that fatigue had remained on the NTSB's Most Wanted List of transportation safety improvements, during which there was no meaningful action taken by regulators in response, to the changes in tolerance for alcohol over the same period, noting that the impact on performance from fatigue and alcohol were similar. 161–170:
However, Vice Chairman Christopher A. Hart and Board Member Robert L. Sumwalt, III dissented on the inclusion of fatigue as a contributing factor, on the grounds that there was not enough evidence to support such a conclusion. It was noted that the same kind of pilot errors and standard operating procedure violations had been found in other accidents where fatigue was not a factor. 171–173:
To state that fatigue was a contributing factor, and thus part of the probable cause, would be inconsistent with the above finding and would, therefore, disrupt this flow of logic. I did not feel, therefore – nor did the Board's majority – that we had sufficient information or evidence to conclude that fatigue should be part of the probable cause of this accident. 171–173:
The FAA has proposed or implemented several rule changes as a result of the Flight 3407 accident, in areas ranging from pilot fatigue to Airline Transport Pilot Certificate (ATP) qualifications of up to 1500 hours of flight experience prior to hiring.One of the most significant changes has already taken effect, changing the way examiners grade checkrides in flight simulators during stalls.
Investigators also scrutinized the Practical Test Standards (PTS) for ATP certification, which allowed for an altitude loss of no more than 100 feet (30 m) in a simulated stall. The NTSB theorized that due to this low tolerance in a tested simulation environment, pilots may have come to fear loss of altitude in a stall and thus focused primarily on preventing such a loss, even to the detriment of recovering from the stall itself. New standards subsequently issued by the FAA eliminate any specific altitude loss stipulation, calling instead for "minimal loss of elevation" in a stall. One examiner has told an aviation magazine that he is not allowed to fail any applicant for losing altitude in a simulated stall, so long as the pilot is able to regain the original altitude. This is not unusual since the standard recovery procedures for recovering from a stall involve trading some altitude for speed, and this is why it is considered much more important to not stall in the first place at low altitude.
On February 12, 2019 (the 10th anniversary of the crash), a remembrance ceremony started.
The Cineflix/National Geographic series Mayday featured the incident in the fourth episode of Season 10, titled Dead Tired.
United Airlines Flight 232 was a regularly scheduled United Airlines flight from Denver to Chicago, continuing to Philadelphia. On July 19, 1989, the DC-10 serving the flight crash-landed at Sioux City, Iowa, after suffering a catastrophic failure of its tail-mounted engine, which led to the loss of many flight controls. At the time, the aircraft was en route from Stapleton International Airport to O'Hare International Airport. Of the 296 passengers and crew on board, 112 died in the accident and 184 survived, making the crash the fifth-deadliest involving the DC-10, behind Turkish Airlines Flight 981, American Airlines Flight 191, Air New Zealand Flight 901, and UTA Flight 772. Despite the deaths, the accident is considered a prime example of successful crew resource management because of the large number of survivors and the manner in which the flight crew handled the emergency and landed the airplane without conventional control.
Aviation safety means the state of an aviation system or organization in which risks associated with aviation activities, related to, or in direct support of the operation of aircraft, are reduced and controlled to an acceptable level. It encompasses the theory, practice, investigation, and categorization of flight failures, and the prevention of such failures through regulation, education, and training. It can also be applied in the context of campaigns that inform the public as to the safety of air travel.
USAir Flight 405 was a regularly scheduled domestic passenger flight between LaGuardia Airport in Queens, New York City, New York, and Cleveland, Ohio. On March 22, 1992, a USAir Fokker F28, registration N485US, flying the route, crashed in poor weather in a partially inverted position in Flushing Bay, shortly after liftoff from LaGuardia. The undercarriage lifted off from the runway; however, the airplane failed to gain lift, flying only several meters above the ground. The aircraft then veered off the runway and hit multiple obstructions before coming to rest in Flushing Bay, just beyond the end of the runway. Of the 51 people on board, 27 were killed, including the captain and a member of the cabin crew.
Continental Airlines Flight 1713 was a commercial airline flight that crashed while taking off in a snowstorm from Stapleton International Airport in Denver, Colorado on November 15, 1987. The Douglas DC-9 was operated by Continental Airlines and was a scheduled flight to Boise, Idaho. Twenty-five passengers and three crew members died in the crash.
Historically, the term pilot error has been used to describe an accident in which an action or decision made by the pilot was the cause or a contributing factor that led to the accident, but also includes the pilot’s failure to make a correct decision or take proper action. Errors are intentional actions that that fail to achieve their intended outcomes. Chicago Convention defines accident as "An occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] except when the injuries are [...] inflicted by other persons." Hence the definition of the "pilot error" does not include deliberate crash.
Bellview Airlines Flight 210, was a scheduled domestic passenger flight, operating as a Boeing 737-200 aircraft from Murtala Muhammed International Airport in Lagos en route to the Nigerian capital Abuja. On 22 October 2005, the plane nose dived and crashed at Lisa Village, Ogun State, killing all 117 people on board. The records obtained by the Associated Press (AP) showed that the captain of a Bellview Airlines flight that crashed had gone back to work as a pilot despite being shot in the head years before. And in another case, a pilots' manual included blank pages instead of key safety information, the investigation further revealed.
On October 14, 2004, Pinnacle Airlines Flight 3701 crashed while flying from Little Rock, Arkansas to Minneapolis–Saint Paul International Airport in Minnesota. No passengers were aboard. Both pilots were killed. Federal investigators determined the crash was due to the pilots' unprofessional behavior and disregard for training and procedures.
Comair Flight 3272 was a Comair flight from Cincinnati to Detroit on Thursday, January 9, 1997. While on approach for landing, the Embraer EMB 120 Brasilia aircraft crashed nose-down 18 miles (29 km) southwest of Detroit Metropolitan Wayne County Airport at 15:54 EST. All 29 aboard, 26 passengers and three crew members, were killed.
Turkish Airlines Flight 1951 was a passenger flight that crashed during landing at Amsterdam Schiphol Airport, Netherlands, on 25 February 2009, resulting in the death of nine passengers and crew, including all three pilots, who died on impact.
Korean Air Flight 801 crashed on August 6, 1997, on approach to Antonio B. Won Pat International Airport, in the United States territory of Guam, killing 228 of the 254 people aboard. The aircraft crashed on Nimitz Hill in Asan, Guam, while on approach to the airport.
Northwest Orient Airlines Flight 6231 was the fatal crash of a Boeing 727 on December 1, 1974 in Harriman State Park near Stony Point, New York, just north of the New York City area. The Northwest Airlines 727 had been chartered to pick up the Baltimore Colts professional football team in Buffalo in western New York.
On December 27, 1968, North Central Airlines Flight 458 (N2045) crashed into a hangar while attempting a night landing in poor weather at O'Hare International Airport in Chicago, Illinois, in the United States. Of the 41 passengers and 4 crew, only 17 passengers and one crew member survived. One person was killed and six injured on the ground.
National Airlines Flight 102 was a cargo flight operated by National Airlines between the British military base Camp Bastion in Afghanistan and Al Maktoum Airport in Dubai, with a refueling stop at Bagram Airfield, Afghanistan. On 29 April 2013, the Boeing 747-400 operating the flight crashed moments after taking off from Bagram, killing all seven people on board.
Asiana Airlines Flight 214 was a scheduled transpacific passenger flight from Incheon International Airport near Seoul, South Korea, to San Francisco International Airport in the United States. On the morning of 6 July 2013, the Boeing 777-200ER crashed on final approach into San Francisco International Airport. Of the 307 people on board, three died; another 187 were injured, 49 of them seriously. Among the injured were four flight attendants who were thrown onto the runway while still strapped in their seats when the tail section broke off after striking the seawall short of the runway. It was the first fatal crash of a Boeing 777 since that aircraft type entered service in 1995.
JAL Cargo Flight 8054 was a charter flight on January 13, 1977, from Grant County, Washington to Tokyo with a stopover in Anchorage. The flight crashed during the initial climb phase, shortly after takeoff from Anchorage due to pilot intoxication.
Empire Airlines Flight 8284 was a cargo flight operated by Empire Airlines for FedEx Feeder between Fort Worth Alliance Airport and Lubbock Preston Smith International Airport, Texas. On 27 January 2009, it crashed on final approach to its destination. Both crew members survived with minor injuries but the aircraft was written off.
Southwest Airlines Flight 1380 was a Boeing 737-700 that experienced an uncontained engine failure after departing from New York–LaGuardia Airport en route to Dallas Love Field on April 17, 2018. Debris from the failed engine damaged the fuselage, causing rapid depressurization of the aircraft after damaging a cabin window. The crew conducted an emergency descent and diverted to Philadelphia International Airport. One passenger was partially ejected from the aircraft and later died. Eight other passengers received minor injuries. The aircraft was substantially damaged. It was the first fatal airline accident involving a U.S. passenger carrier since the crash of Colgan Air Flight 3407 in February 2009, and the first accident involving Southwest Airlines that resulted in the death of a passenger.
