Air France 447 Case Study

Improved Essays
This case is about what really happened in Air France 447 and what were causes of it.
After analyzing the only data available, which were cryptic set of communications, experts found out that mostly the crash happened because of human factors. The weather conditions were bad and after AF447 passed into clouds associated with a large system of thunderstorms, its speed sensors became iced over, and the autopilot disengaged. In the ensuing confusion, the pilots lost control of the airplane because they reacted incorrectly to the loss of instrumentation and then seemed unable to comprehend the nature of the problems they had caused. So neither weather nor malfunction or a complex chain of error caused this crash, but a simple but persistent mistake on the part of one

Also, the misleading stall warnings tricked the pilots into resuming the wrong action when they were on the right track. Information that the flight is in alternate mode is limited which presumably led the pilots to think that the aircraft cannot be stalled.
Operational limitations: Air France was alerted to the problem of misbehaving pitot tubes by other crews and procedures were in place to repair or replace the pitot tubes on all its aircrafts. However this flight was allowed to fly without any modification, assuming there would not be any problem in the face of delay and money involved in grounding the entire fleet.
Lack of division of authority – As I stated earlier, lack of CRM was among crew members. They failed at cooperation. It was unclear to them who were responsible for what and that lead to misunderstanding between them. According to Nutter, it is natural result of having two co-pilots flying the plane. If the captain was there, it would be clear who is in charge. He has command authority and is responsible for everything. But in our case two first officers were in front and it caused

    The captain had a history of showing a weakness in basic aircraft controls and instrument flying, this notwithstanding he was not readily identified. Remedial training is a must for pilots with deficiencies. Colgan Air’s procedures and training at the time of the accident did not specifically require flight crews to cross-check the approach speed bug settings in relation to the reference speeds switch position, such awareness is important because a mismatch between the bugs and the switch could lead to an early stall warning.…

    Knowing this immediately poses the question: Did the engineer who was responsible for sketch the Concorde’s wheel system forget to include the important spacer in the design? The engineers at Air France evidently overlooked fixing these minute problems that would have saved a hundred innocent lives and an airline. Yet these very small problems will now irrevocably haunt them for their entire lives. The fact that the design and the engineering team had known about these problems and had done nothing, raises huge ethical concerns. An engineer’s foremost obligation is to the public welfare and engineers must “approve only those designs that safeguard the life, health, welfare and property of the public” (Engineering Your Future 8Th ED).…

    In the novel, the so called “Catch-22” is the main loophole that is endorsed by the military and that naturally oppresses soldiers. This rule is used to keep soldiers from escaping missions; for example, “Orr was crazy and could be grounded. All he had to do was ask; and as soon as he did, he would no longer be crazy and would have to fly more missions. Orr would be crazy to fly more missions and sane if he didn’t, but if he was sane he had to fly them. If he flew them he was crazy and didn’t have to; but if he didn’t want to he was sane and had to” (46).…

    Charles Mann also believes that the TSA follows useless procedures. He did research on his own and boarded a plane with a false boarding pass. The TSA examined his pass and swabbed it to test for explosives. Charles Mann explains, “The uselessness of the swab, in his view, exemplifies why Americans should dismiss the TSA 's frequent claim that it relies on "multiple levels" of security”(Mann 2013). Charles Mann is not a biased author because he has no expertise on the subject of airport…

    While the total loss of hydraulics is considered virtually impossible since they all are separate systems, the hydraulics in the plane shared the same route through the tail which is where penetration occurred. This is what led to the engine and hydraulic failure, which caused the pilots to lose control of the plane leading to the crash at SUX airport. There are a few ethical considerations at work with the crash of the United Airlines Flight 232. Firstly, there is the failure of the United Airlines maintenance personnel and processes for not being able to identify the existing cracks in the fan disk which was indicated by the presence of a penetrating fluorescent dye. United Airlines could have of been able to detect the crack if they had more personnel on the maintenance, however, having to employ more people would lead to losing money.…

    Mechanical errors also cause 22% of aircraft accidents. In mechanical error, systems may fail beyond the capability of the crew. Some of the mechanical errors have been as a result of poor plane design. Bad weather is responsible for 12% of plane crashes and is the reason most of the times planes are grounded till the weather clears. Fog, heavy winds, and lightening can disable plane systems to cause and accident.…

    Those men that stopped our plane were trying to find any of their political adversaries that might be on board and luckily they didn’t involve any non-related parties in their conflict that day. Our plane was the last large plane to land in Angola for a long time as that situation could have devolved into the horrific event. When I made this realization at the age of nine, the way I viewed the world around changed and brought with it a higher acknowledgement of my surroundings. Becoming aware that not everything in the world is safe and that there are dangers around that can bring you into its orbit can be seen as the death of innocence but I see it the acknowledgement of…
