IntroductionThis mission will be a research regarding the crash of Crossair flight 3597 at Zurich airport on November 24, 2001, the objective of this mission is to reflect, list and justify 3 contributing factors involved in the accident in the context of flight operations. Another objective of this mission is to show how we can learn from this accident, and at the same time prevent any future accidents that could be similar to this one. Facts about the crash of Crossair Flight 3579 There were several causes for the accident, such as the type of approach. , weather conditions, dangerous attitudes and violation of the minimum descent altitude. There was a sudden change in runway used for landing, due to the new law closing runway 14, causing the runway to change to runway 28. Which required the pilot to fly the approach at a very high frequency (VHF) to omnidirectional radio range (VOR) or distance measuring equipment (DME), because Runway 28 was not equipped with an instrument landing system (ILS). The VOR/DME approach is more difficult than the precision approach, and the pilot has previously demonstrated major and repeated deficiencies in his ability to operate an aircraft safely, particularly his ability to perform a complicated approach and use modern instruments. Therefore, the type of approach is one of the causes that led to the accident. Weather conditions at the time of the accident were poor, with low visibility and a cloud base. The visual range measured by the airport is greater than the minimum; however, this was not accurate. The calculation of weather minimums at the airport used data from a station far from Runway 28, so the weather minimums did not reflect actual conditions on Runway 28. Another plane that landed had reported the wrong weather conditions during landing...... middle of paper ...me. Another weather minimum update was given by one of the flights that landed on runway 28, the pilot of that flight said the weather minimum was only at the limit and the runway did not was only spotted at 1.3 miles. The weather is one of the contributing factors because if the weather minimum had been calculated accurately, this would have avoided the accident because the pilot would have been forced to cancel the approach. ConclusionIn conclusion, I believe that all factors are important and interconnected. Because according to the “Swiss Cheese” model, a single factor is not capable of causing disaster, disaster will only happen when all the factors coincide. Therefore, all factors are responsible for the crash of Crossair Flight 3597 and must be examined thoroughly, in order to learn from past mistakes and prevent any similar future accidents...
