There are many airplane accidents a year. On an average, 70 –80% are human error. Though there are many other factors, such as design factors, management, and weather factors, human error is the largest. Each one of these factors played a certain role in the three articles of accidents. The BOAC Comet, the PSA crashes in San Diego, and the Air Florida crash in Washington D.C., were analyzed differently, taking into consideration each possible factor. Within the follow, each accident will be discussed.
The cause in every accident of the BOAC Comet was a design factor. The pressurization limitations were determined wrongly. In the mid air collision in San Diego, the cause was human error of the Cessna pilot for changing headings, the Boeing for not being sure of having the right traffic insight, and the tower for not warning the aircrafts they were very close together when his warning went off. Finally, the Air Florida crash, investigators took into consideration the factors of the weather, engine performance, and pilot error.
Principle Mishaps / Human Factors
The Comet DH-106 was the first jetliner to carry passengers. The person to give credit for this accomplishment would be de Havilland. The DH-106 carried thirty-six passengers, had a pressurized cabin, a ceiling of 40,000ft, and traveled 500mph. According to the investigation of the BOAC Comet, the reason the comets were exploding, was because of the pressurization within the cabin. There was no real sufficient information prior to the flights that indicated there was a problem. At first, the pilots of the comet does not know that in roll out, they need to use a lesser angle of attack and keep the nose on the ground longer. Many pilots flying the Comet had little to no experience flying this aircraft. There was a singular error in the engineering of the aircraft. The structure of the aircraft was said to with stand a certain amount of pressure. Today, the skin of an airplane is much thicker. Also, the windows are a lot smaller. In actuality, the plane could not with hold this amount of pressure and stress.
In the PSA crash in San Diego, information was sufficient to both pilots prior to mid air collision. Both aircrews were aware of one another. The 727 aircrew assumed they had the right traffic insight to avoid collision. The Cessna made the mistake of altering his designated heading from tower. Air Traffic Control (ATC) made the mistake of not notify either of the aircrews of collision when the warning went off in the tower. If the Cessna had informed tower of their heading change, this...
