Human errors in aviation accidents



When you Google human errors in aviation accidents or aircraft accidents you get a whole lot of stuff to sift through. The one thing or statement that is usually with-in the first paragraph is human error causes more than half of all aviation accidents. Actually human error has been documented as a primary contributor to more than 70 percent of commercial airplane hull-loss accidents. So what does this really mean to us? When you read a report and it usually says that pilot error of some sort caused the accident, the question has to be asked, did it really? Or were there other factors involved.
What are human factors? The term "human factors" has grown increasingly popular as the commercial aviation industry has realized that human error, rather than mechanical failure, underlies most aviation accidents and incidents. If interpreted narrowly, human factors are often considered synonymous with crew resource management (CRM) or maintenance resource management (MRM). However, it is much broader in both its knowledge base and scope. Human factors involves gathering information about human abilities, limitations, and other characteristics and applying it to tools, machines, systems, tasks, jobs, and environments to produce safe, comfortable, and effective human use. In aviation, human factors is dedicated to better understanding how humans can most safely and efficiently be integrated with the technology. That understanding is then translated into design, training, policies, or procedures to help humans perform better.
Despite rapid gains in technology, humans are ultimately responsible for ensuring the success and safety of the aviation industry. They must continue to be knowledgeable, flexible, dedicated, and efficient while exercising good judgment. Meanwhile, the industry continues to make major investments in training, equipment, and systems that have long-term implications. Because technology continues to evolve faster than the ability to predict how humans will interact with it, the industry can no longer depend as much on experience and intuition to guide decisions related to human performance. Instead, a sound scientific basis is necessary for assessing human performance implications in design, training, and procedures; just as developing a new wing requires sound aerodynamic engineering.
As in the pictures below, weather you’re the mechanic performing the maintenance or the pilot flying the plane, is it going to be your fault for what went wrong. As Smoky the Bear say’s only you can prevent forest fires, you can also help prevent aviation accidents by doing things the right way.
