Planes have never crashed because of a single problem, and there is almost always a combination of factors that lead to an accident.
Although flying is extremely safe, a typical cause of a plane crash is a mechanical defect, such as engine failure, engine failure, or mechanical failure. Mechanical glitches alone could be handled correctly by the pilot and should not mean that the plane crashed, and there was never a single cause attributed to a plane crash. If an aircraft has a serious technical problem but does not result in the loss of the aircraft, pilot error and / or mechanical failure can be expected, as the pilots subsequently mishandled the aircraft that caused the crash, even if they did not cause the problem.
So some factors are causal, such as mechanical defects, pilot error and mechanical failure, but not all cause an aircraft crash.
As a result, statistics on the cause of plane crashes are not always clear, and air accidents never occur for a specific reason. There are always a number of factors that contribute to a plane crash, such as mechanical defects, pilot error and mechanical failure. Controlled flight is an example of pilot error, but pilot fatigue combined with bad weather or technical problems could be an example.
However, if these factors are not present, crashes can occur due to other factors such as mechanical defects, pilot error or mechanical failure.
The Swiss cheese model, known in the industry as the “cheese model,” if you imagine different cheese blocks lined up side by side, you will probably see a hole, as if it were a slice of cheese. However, if the holes are in different places, you will not even be able to see what is in each slice of cheese!
In the Swiss cheese model, the holes are lined up, meaning that all the factors come together to cause an accident. At this stage of flight, a crash is most likely due to a combination of factors, such as fuel shortages, poor flight control or a failure of a control system, among others.
Boeing has released the following statistics on the number of accidents per 100,000 flight hours in the United States. Statistically, the area where an accident is most likely is land, which statistically borders on land – on the sea – and land on the air.
