Human Error Case Study On December 8, 2005, a Boeing 737-7H4, N47WN- operated by Southwest Airlines- was involved in an accident at Chicago Midway International Airport. The airplane went through the perimeter fence and blast fence of the airport and knocked an automobile on the adjacent road before coming to a stop; the airplane was substantially damaged (NTSB, 2005). This case study applies the data analysis tools of the Human Factors Analysis and Classification System (HFACS) to this accident to analyze the human error aspects of the accident.
HFACS framework embodies four levels of human failure (unsafe acts, preconditions for unsafe acts, unsafe supervision and organizational influences) that lead to an accident (Harris, 2011). Errors correspond to human activities that fall short of producing intended outcomes (Wiegmann and Shappell, 2012). In this accident, the captain made a skill-based error by failing to prioritize his attention; he told the investigators that the use of the autobrake system diverted his concentration from thrust reversers. Violation refers to willful discount for safety rules and regulations (OConnor & Cohn, 2010). Violation committed in this case if failure by the pilots to adequately familiarize themselves with the autobrake system; they were using it for the first time. They both resulted into delayed response.
Preconditions for unsafe acts refer to incident resulting into unsafe acts (Wiegmann and Shappell, 2012). In this case, the pilots lacked effective communication/coordination. This can be seen when the first officer took away the captain’s hand from the thrust reverser levers rather than directing him to engage thrust reversers. Under unsafe supervision, the pilots were not allowed sufficient brief time as they departed without the latest updated weather information and dispatch documents and only evaluated and analyzed the procedures for autobrake system while en route.
Southwest airlines failed to provide precise landing calculations to her pilots; all of the landing calculations were completed by the On Board Performance Computer (OPC) which wrongly completed the calculations. Hence, organizational influence level error.
In summary, e accident was caused by divided attention, insufficient preparation, lack of communication/coordination and unclear landing calculations. The autobrake system distracted the pilot’s attention and unfamiliarity with such system, together with inappropriate communication, hampered the response time. Inaccurate results provided by the OPC also contributed to the accident.

Technology and Human Error in Aviation

...?Running Head: TECHNOLOGY AND ERROR IN AVIATION Technology and Human Error in Aviation Introduction Technology is the product of human intelligence. In fact, man is so smart that he created technology to be smarter than him, so it seems. The computer is the basic technology used in aviation systems. Computers do extraordinary jobs beyond human capabilities. It is thus no wonder that computers are resorted to when things do not go effciently or effectively, hoping that a simple “delete” or “backspace” key will undo the errors. One tends to forget that technology has limitations since it only works according to how people design, manage,...

Devastatingly Human - An Analysis of Registered Nurses' Medication Error Accounts--NURSING

...?Medication Errors: Devastatingly Human Dispensing medicines is a risky task and medication errors are common in nursing profession. Camire et al (2009) opined that medication errors are the most common errors in nursing profession and they account for 78 percent of serious medical errors in the critical care unit. The technicality, complexity and the chaotic working atmosphere of nurses make nurses more amenable to medication errors. Nurses are taught that administration of medication is an individual responsibility and that the blame for administering wrong medication is on the individual who has administered the drug....

Proof of God's existence and Human error

...? Descartes – Proof of God’s Existence and Human Error Descartes was one of the philosophers that endeavored to prove the existence of God by providing logical reasons. He provided this discussion in his works titled Meditations on First Philosophy. Descartes provided two proofs of the existence of God which are discussed and analyzed below. First proof of the existence of God given by Descartes is that; something cannot be created from nothing. It is one of the logics Descartes used to prove the existence of God. It is a logical reality that in order for something to be created, someone must create it. According to Descartes, in order for an idea to contain objective reality, it must be derived from a...

Human Error within Safety Critical Systems

...? Human Error Human Error Human error simply refers to an error that is made by human beings. However, we find that it gets somehow complicated than just that. It is true that mistakes are made by people; but the most important thing is why they make the mistakes. With that taken into consideration, human error is when an individual makes a mistake because that particular individual made a mistake, contrary to being influenced or even confused by some other design factors. It is also referred to as Operator Error. Nevertheless, human...

Managing Human Error in Aviation

...Management (CRM) resolves these issues to some extent. CRM dissects the cultural, societal and company, psychological and social human factors in communications and decision making. A more collaborative management ensues from this training. All crew members can speak out on safety issues. One study showed an Asian based airline’s pilots considered chain of command to take precedence over safety. The net result is training teams, rather than leaders and followers. This same technique applies to emergency room teams, surgical teams and first responders. The main concern using this paradigm is communicating the facts of a situation for a more clear picture.

Human Error in Aviation

...Unit Accidents are inevitable because they are not only part of human life, but also intensified by the technologies developed by man. For instance, the aviation industry has witnessed several accidents most of which are attributed to human error. This paper analyses human errors as the main cause of aviation accident, especially in the United States. Human error occurs in the form of system errors arising from people failing to do their duties, failures resulting from wrong steps and decisions, and finally, errors resulting from the deviation from standards, or the aviation staff...

Human Error in Aviation

... Human error in aviation Abstract It will not be reasonable when an individual assumes that a person can be in a position to operate continuously without ever making a mistake. Therefore, human error is considered real and a common problem that cannot be in the aviation industry. Unfortunately, those who encounter this error, usually, have a disastrous result. The huge number of deaths can result from one momentary lapse of judgment. This can cause loss of hundreds of millions in the industry due to damages incurred. Introduction Human error in...
