Introduction
This assignment is going to be a research regarding the crash of Crossair flight 3597 at Zurich Airport on 24 November 2001, the objective of this assignment is to reflect, list and justify 3 contributing factors involved in the accident within the flight operations context. Another objective of this assignment is to show how we can learn from this accident, and at the same time prevent any future accidents that might be similar to this accident.
Facts about Crossair Flight 3579 Crash
There were several causes of the accident, such as approach type, weather, hazardous attitudes, and violation of minimum descent altitude.
There was a sudden change of runway used for landing, due to the new law that closes runway 14, causing the runway to change to runway 28. Resulting to the pilot having to fly the very high frequency (VHF) Omni-directional Radio-Range (VOR) or Distance-measuring Equipment (DME) approach, as runway 28 did not have instrument landing system (ILS). The VOR/DME approach is more difficult as compared to the precision approach, and pilot has previously shown repeated major deficiencies in his ability to safely operate an aircraft, in particular the ability to fly complicated approach and use modern instrument. Hence, the approach type is one of the causes that led to the accident.
The weather during the accident time was poor, with low visibility and cloud base. The visual range measured by the airport is above the minimum; however, it was not accurate. The airport calculation of the weather minimums used data from a station distant from runway 28, causing the weather minimums not reflecting the actual conditions on runway 28. Another aircraft that landed had advised of the poor weather condition at the run...

...me. Another weather minimum update was given by one of the flight that have landed on runway 28, the pilot of that flight says that the weather minimum was only borderline, and runway was only spotted 1.3 miles out. The weather is one of the contributing factors is because if the weather minimum were to accurately calculated, it would have avoided the crash as the pilot would have been forced to cancel the approach.
Conclusion
In conclusion, I think that all the factors are important and interconnected, as according to the “Swiss Cheese” model, one factor alone is not capable of causing the disaster, the disaster will only happens when all the factors coincide. Hence, all the factors are responsible for the crash of Crossair flight 3597, and are to be reviewed throughly, so as to learn from the past mistakes, and to prevent any future accidents that are similar.

Some of the earlier tests of the seals brought to the attention of the engineers that the seals where prone to failure when exposed to extreme temptures and due to the location of the seals not staying within the parameters of the seals would cause a catastrophic failure. Other warnings where not taken into account when the launch days drew closer, the unusually cold weather caused delays in the original launch date and the on the new launch day the temtures around the seals where estimated “to be 28degrees +/- 5 degrees Fahrenheit” (NASA, n.d). According to the NASA investigation
In the aftermath of the collapse of the walkways, investigations revealed that a breakdown in communication between Jack D. Gillum and Associates and Havens Steels Company was largely responsible for the fatal design flaw.
This review of the inquiry of Air India Flight 182: A Canadian Tragedy will examine the numerous objectives of the inquiry. The review will examine the mandate, methods, and the key findings by the commission. An evaluation will be made on the recommendations set out in the inquiry and the impacts of the recommendations that have been implemented in addition to evaluating whether or not all the recommendations have been implemented in Canada. This review will also evaluate the context in which the particular group of Sikhs and Indians were treated as a victim, terrorist, or witness.
The investigation was also one of the largest international law enforcement endeavors of its time (Birkland, 2004). This tragedy, like most devastating events, changed the course of history and is a directly affected aviation safety as we know it today. The forensic findings during the investigation also helped change aviation safety policy and procedures. The result was improvement in training for airport security personnel, examination of quality control issues and heightened aviation security regulations (Birkland,
Even though there were many factors contributing to the Challenger disaster, the most important issue was the lack of an effective risk management plan. The factors leading to the Challenger disaster are:
56 passengers are injured. Three are dead. People are shocked, terrified, confused. What happened on TPA flight 545? Why did it happen? Could it have been prevented? A very popular late night news show has the power to totally destroy an innocent airplane manufacturer. A race between a high executive working for Norton, and a news reporter from Newsline to outwit one another has begun.
After World War II there was an excess of aircraft and trained pilots in the United States, which significantly increase in private and commercial flights. An increase in the use of private aircraft and large passenger planes meant an increase in the possibly of aircraft safety incidents. Even though safety measures had been put in place to tend to large number of aircraft in the skies, in late 1950’s there were two unfortunate accidents that finally led to legislation that would be a major change to the world of aviation that affects us even today. The introduction of the Federal Aviation Act of 1958 spurred several changes in aviation that eventually led to the creation of the Federal Aviation Administration.
Due to the new noise law, Runway 14 is down after 10pm in order to keep out of German Airspace and the aircraft was diverted to Runway 28. Runway 28 has less precise technology as compared to Runway 14. Runway 28 uses a less accurate navigational system which is VHF Omnidirectional Range / Distance Measuring Equipment (VOR/DME) as VOR/DME does not provide guidance on the plane’s altitude and the approach to Runway 28 was not equipped with Minimum Safe Altitude Warning (MSAW) thus the pilots are not warned about the greater risk of crashing into a terrain.
Technology was a lacking factor on that January 12th day of 1888, which did not give those people warning on what was coming their way. Forecasters that were subject to human error did not have access to information that could have been provided by the Army. Certain weather terminology was forbidding to use for the fear that some cities were immune to these storms. During that day of the blizzard there were no advanced warning signs (outside of the temperature dropping) that the worst blizzard was about to occur, technology had not yet reached that point. If on that day or any day, the Army would have made weather a top priority some of those children could have been saved or at home with their families instead of dying alone in the snow. Forecasters could only get weather information the day of or twenty-four hours before. Many of the weather disasters were not accurate, so if there were any weather predictions good or bad, the people had no choice to believe it. Both parties really did not know any more than the
While model grid spacing’s were becoming less sporadic going form 15-20 to 38 grid points over the great lakes, the model resolution was still not sufficient enough to pick up on this type of event. Forecasters wanted a high resolution mesoscale model but the model is only as good as the data that is incorporated into it. There needed to be vastly improved data and they “called for a high resolution (temporal and spatial) observational network that included automatic weather stations able to report surface temperature, pressure, and precipitation in real time; wind profilers able to estimate wind speed and direction at various levels; and a new Doppler radar system that could locate snow bands 100 kilometers away.”
Safety in the ethics and industry of aerospace technology is of prime importance for preventing tragic malfunctions and crashes. Opposed to automobiles for example, if an airplane breaks down while in mid-flight, it has nowhere to go but down. And sadly it will often go down “hard” and with a high probability of killing people. The Engineering Code of Ethics states first and foremost that, “Engineers shall hold paramount the safety, health and welfare of the public.” In the aerospace industry, this as well holds very true, both in manufacturing and in air safety itself. Airline safety has recently become a much-debated topic, although arguments over air safety and travel have been going ...
Pilots with Big Island Air that were scheduled with a departure time of 7am or earlier would always receive a morning weather report to use as a reference and this weather report would always be included on their flight plane and weather fo...
“At 12:42 p.m. the air was perfectly calm for about one minute; the next minute the sky was completely overcast by heavy black clouds which, for a few minutes previous, had hung along the western and northwestern horizon, and the wind veered to the west and blew with such violence as to render the position of the observer on the roof unsafe. The air was immediately filled with snow as fine as sifted flour” (Potter). No one expected the blizzard that would soon come rolling over to create some of the unfortunate deaths. Now, the questions are what exactly happened during the storm, how are snowstorms created, and what damages it caused.
Another theory is that the pilot, Jason Dahl might have purposefully crashed the plane to prevent the hijackers from taking it over. Or perhaps that Dahl had cut off the planes fuel with out the hijackers being aware. It was said that the plane looked like it went straight down; and that the plane had almost completely disintegrated on impact leaving a hole several feet deep.
