Flight 1420 of American Airlines claimed the lives of 11 passengers on June 1, 1999. From the NTSB report one can conclude that there were several human factors that contributed to the accident of American Airlines flight 1420. Examples include unsafe acts by the pilots, violations that represent a willful disregard for the rules and regulations that govern safe flight as well as fatigue and substandard practices of operators which in this case include communication and coordination between the pilots and the air traffic controller. This paper will talk about these

The unsafe acts of aircrew can be loosely classified into two categories: errors and violations (Reason, 1990). In this particular accident the pilots both made errors and violated the rules and regulations implemented by American Airlines. The two factors I believe played a vital role in this accident are unsafe acts of the pilots which include error and violation and precondition for unsafe acts which includes adverse mental state.
Error
Pilot error falls under the unsafe act of the HFACS model. In the NTSB report it is stated air traffic controller in Little Rock, AK warned the American Airlines dispatcher that there was a storm heading to Little Rock but the dispatcher was confident that the pilots could make it before the storm hit. As they proceeded to fly, they were in contact with the air traffic controller in Little Rock, AK who was sending them reports of the current weather conditions. Several times they had to change their flying path to land on a certain runway since the storm was a factor in this incident. This only caused the pilots to have a heavy workload in keeping track of certain storm elements such as the rain, the clouds and the wind. By having these distractions it can be concluded that the pilot was not able to determine his exact location while
One notable event on Riker's Island was Northeast Airlines Flight 823. According to Correction History, “On February 1, 1957, at around 6:00 p.m. a plane of the Northeast Airlines to Miami from LaGuardia Airport crash-arrived on the penitentiary grounds on Riker's Island, a couple of minutes in the wake of taking off from the field”. In addition, “there were ninety-one travelers on the plane, of whom twenty were murdered as a result of the crash and blast” (Correction History). As indicated by Gabrielle Fonrouge (2017), According to Gabrielle Fonrouge (2017), “the Miami-bound plane crashed into a patch of trees on Rikers Island, ripping off its wings and bursting into flames less than a minute after take-off”. Detainees dashed to the plane crash to help survivors. As agreed by Lion Calandra (2017), “Rikers Assistant Deputy Warden James Harrison made the unprecedented decision to release prisoners to aid in the rescue”. (1) “Harrison gave the order to release more than 50 inmates known as “trusties” prisoners whose good behavior had earned the guards’ trust. (2) “They raced to the scene to help stunned passengers and crew” (Lion Calandra, 2017).
This crash is considered to be the second deadliest aviation accident at the time in the US.
On a snowy day on March 10, 1989, Air Ontario flight 1363 was initiating take off at Dryden Airport, Canada by Captain George C. Morwood. It was the second part of the flying schedule for that day which was a round trip from Winnipeg to Thunder Bay, with midway stops at Dryden. Both pilots were highly experienced. Captain Morwood had been flying for almost 35 years and his first officer, Keith Mills, has had over 10,000 hours of flying. However, both pilots were fairly new to the aircraft, which was an F28-1000, having less than 150 hours combined.
On the morning of September 11th, 2001, at 8:46 a.m., the United States was attacked by members of the terrorists from Al-Qaeda. Nineteen hijackers from Egypt, Saudi Arabia, the United Arab Emirates, and Lebanon, hijacked four American passenger jets bound for California. Both flight 11 of American Airlines and flight 175 of United Airlines would be flown into the north and south towers of the World Trade Center in New York City. American Airlines flight 77 would be flown into the Pentagon in Washington D.C. Finally, United Airlines flight 93 would be flown into a farmer’s field in Shanksville, Pennsylvania, failing to reach
In February of 2009, Colgan Air flight 3407 crashed while on approach killing forty-nine people on board as well as one on the ground according to the official National Transportation Safety Board (NTSB) Accident Report (2010). In February of 2008, go! flight 1002 ignored several radio calls after departure and eventually flew past its destination and continued over open water according to the NTSB’s Report (2009). In April of 2007, Pinnacle Airlines flight 4712 overran the runway after landing at its destination airport. According to the NTSB’s official Accident Report (2008), there were no injuries. The incidents and accidents listed above all have one common factor: fatigue. Fatigue was shown to have played some role in Colgan 3407, go! 1002, and Pinnacle 4712.
On February 24th, 1989 United Airlines 811 (UA811) took off from Honolulu International Airport, Hawaii (HNL) for a regularly scheduled 8 hour flight to Auckland, New Zealand. The routine flight aboard the Boeing 747-122 had left Los Angeles, California enroute to Sydney, Australia, but made a scheduled intermediate stop in Honolulu and would make one more in Auckland (NTSB, 1992, p. 1). UA811 departed Gate 10, at HNL, 3 minutes late with 3 flight crew, 15 flight attendants and 337 passengers onboard (NTSB, 1992, p. 1). The flight took place in the aftermath of Lockerby and additional boarding procedures were in place adding to an extended passenger boarding process. The second officer noted that all cabin and cargo door lights were out prior to departing the gate (NTSB, 1992, p. 2). The captain was at the controls for the takeoff from HNL runway 8R at 0152:49 HST (NTSB, 1992, p. 2). “The flightcrew reported the airplane’s operation to be normal during the take off and during the initial and intermediate segments of the climb” (NTSB, 1992, p. 2). Due to thunderstorms enroute the flightcrew elected to deviate left of course and the captain left the passenger seat belt sign “on”. When climbing between 22,000 feet and 23,000 feet at 300 knots the flightcrew
Flight 1420 was a disaster that taught the aviation community several important lessons. All the Seven Major Elements of Aviation safety can be seen as contributing factors but the greatest factor was human error and the impact of pilot fatigue. With proper preventative measures, the pilots probably would have had the time to arm the MD-82’s spoiler system and the flight would have touched down safely.
On a clear Tuesday Morning, approximately nineteen (19) militants of a radical group known as Al Qaeda boarded and hijacked four different airliners. The First Aircraft, a Boeing 767 flying out of Boston, Struck the North Tower of the World Trade Center at 0845 local time. The Second, another Boeing 767, struck the South Tower of the World Trade Center approximately eighteen (18) minutes later. As millions of Americans watched the events transpire on T.V. a third aircraft, a Boeing 757, collided with the Pentagon at approximately 0945 local. A fourth aircraft, United-Airlines Flight 93 out of Newark New Jersey, was hijacked. The passengers onboard attacked the hijackers and the plane plummeted toward the ground crashing into a field in
The American Airlines McDonnell Douglas MD-82 carrying 143 passengers attempted a landing in fierce winds just shy of midnight on June 2, 1999. As the flight was en-route to Little Rock the Air Traffic Control (ATC) facility at the Little Rock Airport reported to the pilots that a thunderstorm had moved into the area with strong
The airplane took off northeast from Runway 4 at 3:25 pm, Skiles was the first to notice flock of birds approaching the aircraft while passing through an altitude of about 2,800 feet on the initial climb out to 15,000 feet. According to the flight data recorder (FDR) data, the bird encounter occurred at 3:27 PM when the passengers and cabin crew reported hearing “very loud bangs” from both engines and seeing flaming exhaust along with a strong odor of unburned fuel in the cabin (World). The airplane was at an altitude of 2,818 feet and a distance about 4.5 miles north-northwest of the approach end of runway 22 at LaGuardia Airport. Even though the airplane was struck by flock of birds, the airplane’s altitude continued to increase while the airspeed decreased until 3:27 PM, when the airplane reached its highest altitude of roughly 3,060 feet at roughly 185 knots (213 mph). The altitude then started to decrease as the airspeed started to increase reaching 215 knots at 3:28 PM at an altitude of about 1,650 feet. At this point, Sullenberger took over the controls while Skiles begins going through the emergency procedures checklist in an attempt to restart the engines. Sullenberger asked the departure controller if they could attempt an emergency landing in Teterboro Airport as a possibility and was quickly gained permission to do so but he made his intention clear to bring the plane
On August 14, 2013 United Postal Service (UPS) Flight 1354, an Airbus A300-600, crashed short of runway 18 during a localizer non-precision approach to runway 18 at Birmingham-Shuttlesworth International Airport, Birmingham, Alabama (BHM). The pilot and first officer were the only two people on board and both were killed. The aircraft was completely destroyed by ground impact at the post-crash fire (National Transportation Safety Board [NTSB], 2014, p. 13).
Multiple factors were contributing to American Airlines fatal accident in 1999. To identify the factors and different issues with American Airlines Flight 1420 the SHELL model will be used. One of the major cause of this accident was a breakdown in Liveware-Software. Liveware-Software investigates procedures, manuals, checklists and standard operational procedures (ICAO SHELL Model, 2016).
This assignment will be discuss, analyse and critical evaluate on the incident of aircraft Boeing 737-400 with flight registration number G-OBMM near Daventry on 23 February 1995. This assignment will be base on the report of Air Accident Investigation Branch (AAIB), Department of Transport with report number 3/96 (EW/C95/2/3). This aircraft incident has been choose because of the report provided by AAIB was clear with the sequences of incident, information of the aircraft operator and the Authority, complete with clear finding and factors that lead to incident also provide with 15 safety recommendations to prevent this type of incident occur again in the future.
Among the four aircrafts, two belonged to American Airlines and another two belonged to United Airlines. The first hijacked aircraft to take-off, American Airlines Flight 11, was boarded by five hijackers: Mohammed Atta (a trained pilot and ringleader of the attacks), Abdulaziz al-Omari, Waleed al-Shehri, Wail al-Shehri, and Satam al-Suqami. At 7:59 a.m., Flight 11, holding 81 passengers (including the hijackers) and 11 crew members, takes off from Logan International Airport runway 4R, bound for Los Angeles International Airport. Nearly 15 minutes later, the second hijacked aircraft, United Airlines Flight 175, containing 56 passengers and nine crew members, takes off from Logan International Airport runway 9 and heading towards Los Angeles International Airport.
The above mentioned airplane was a planned commercial passenger flight that took off from LaGuardia Airport, New York destined for Charlotte Douglas Airport in North Carolina on January 15, 2009. Six minutes after takeoff, the airplane was successfully abandoned in Hudson River after striking multiple birds during its initial climb out. The crew reported by radio two minutes after takeoff at an altitude of 3,200 feet, the Airbus experienced multiple bird strikes. The result of this multiple bird strikes, which occurred in northeast of George Washington Bridge was compressor stalls as well as loss of thrust in both engines. The Airbus was ditched in Hudson River after the aircrew
