1 Introduction
The aircraft safety is a continuous improvement with the aid of new technology and aircraft accident investigation recommendations. These help to sufficiently and effectively manage the safety aspects along with efficient monitoring and reviews, and enhance the applicability of Safety Management System (SMS) elements in the organization.
The aim of this report to identify the insufficiency and inefficiency of SMS elements deployed in the organization results into major accident. This is analysed and discussed with the help of ValuJet Airlines Flight 592 accident. by identifying the contributing factors and latent errors.
1.1 Summary of Flight 592 Accident
The Flight 592 was a McDonnell Douglas Model DC-9-32 operated by ValuJet

Further strengthening is done by involving oversight in various phases of design and with right level of oversight. Moreover, Technical failure is relatively rare, regulatory oversight is strong, and the engineering of protective devices is highly developed in complex aviation system functions such as production and transportation. However, there have been misconceptions in people about complex systems which include operator’s intentions and the operating environment about the design and corresponding rationale and boundaries of safe operations.
The overall study concludes that design can contribute to accidents. However, it was unable to differentiate the failure is due to design stage or type of safety oversight. It also discussed about people’s misconceptions while designing a complex system. Safety studies and safety assessments are conducted with an aim of preventing reoccurrence of similar accidents with the help of practical solutions which are usually operational, training etc, rather than redesign. Additionally, use of best practice material and guidance on Human Factors can be considered in design

However, they may also contribute to accidents/incidents due to several factors. This demand for considering higher levels of safety performance in certification processes. To address this, the European Commission (EC) started a project of risk modelling called ‘Aviation Safety and Certification of new Operations and Systems (ASCOS)’. This will provide guidance to eliminate certification obstacles and assist in implementation of new technologies. In this context risk model is an improved certification. The model mainly consists of developed fault trees and Event Sequence Diagrams (ESDs) along with expert opinion to quantify the data.
The risk model has three steps:
1. Precursor identification by Future Aviation Safety Team (FAST), a group consisting of multi-disciplinary, international safety experts who identify and publish emerging/future risks. They assess interactions and overlaps or gaps among the system, and maintain a repository of Areas of Change (AoC).
2. Link the identified precursor with a least possible level of derived base events of fault tree analysis.
3. Use experts to link each precursor with a base event by performing safety assessment and reviews
The risk model representation of Safety culture and safety management is ideally done by linking the base event of the fault trees with the components of safety culture and safety management. However,
When it comes to safety most people think they are safe, and they have a true understanding on how to work safe. Human nature prevents us from harming ourselves. Our instincts help protect us from harm. Yet everyday there are injuries and deaths across the world due to being unsafe. What causes people to work unsafe is one of the main challenges that face all Safety Managers across the world.
According to “A Human Error Approach to Aviation Accident Analysis…”, both authors stated that HFACS was developed based off from the Swiss Cheese model to provide a tool to assist in the investigation process to identify the probable human cause (Wiegmann and Shappell, 2003). Moreover, the HFACS is broken down into four categories to identify the failure occur. In other words, leading up to adverse events the HFACS will identify the type error occur.
...ial approaches which are Normal Accident and HROs, although it seems certain that both of them tends to limit the progression that can contribute toward achieving to highly protective systems. This is because the scope of the problems is too narrow and the potential of the solutions is too limited as well. Hence, Laporte and Consolini et.al., (1991) as cited in Marais, et.al., (2004) conclude that the most interesting feature of the high reliability organization is to prioritize both performance and security by the managerial oversight. In addition, the goal agreement must be an official announcement. In essence, it is recommended that there is a continuing need in the high risk organizations for more awareness of developing security system and high reliability environment in order to gain highly successful method to lower risk in an advance technology system.
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 ...
... problem are under constant development and analysis, in a hope to avoid these situations. The civilian industry continues to lead in development due to commercialization, with the military not far behind. The only real deficiency in CRM program development seems to be the area of general aviation as described earlier. Until this problem is addressed, there will still be a glaring weakness in the general area of aviation safety. However, with the rate of technology increase and cheaper methods of instruction, we should begin to see this problem addressed in the near future. Until then, aviation will rely on civil commercial aviation the military to continue research and program development for the years to come, hopefully resulting in an increasingly safe method of travel and recreation.
History has shown the need for continuously improving regulations which govern air operations and maintenance of aircraft. In this sense, military airworthiness authorities are committed to this task and, in recent years, military aviation regulatory frameworks have progressed considerably. Military aviation operations are spread across the world originating the necessity of having analogous regulatory framework in order to facilitate operations. Australian Defence Force (ADF), driven by the same aim, has developed the Defence Aviation Safety Regulations (DASRs) derived from the European Military Airworthiness Requirements (EMARs). Moreover, the European Defence Agency (EDA) has pioneered the interoperability area by establishing a recognition
Data collection and processing in the aviation industry is a very important tool for the companies in this industry to conduct the internal evaluation of the company’s Safety Management System (SMS). Through such evaluations, the company is able to determine whether SMS is in line with its expectations and objectives. The company should take into account the findings of the evaluations performed on a previous date. Furthermore, there is a need to use the data carefully to ensure that the safety criticality of the program under evaluation is put into account. A well guided data collection, processing and trending in the aviation industry can bring revolution in the evaluations defined in aviation companies (Vinshnu, 2014).
As the development of aviation industry grows, more and more aircraft crashes occur. There are many reasons that lead to aircraft crashes, but one of them, is because of improper aircraft maintenance. Why is proper aircraft maintenance so important? Proper aircraft maintenance is critical in order to keep the aircraft can function properly, every aircraft part is in good condition and ensure the safety of pilots and passengers. Proper maintenance has many parts. The most common part is inspections, which pilots do them every day; the main part is overhaul and repair of an aircraft; and maintenance documentation is another important part of aircraft maintenance which improper maintenance documentation has caused many incidents.
This term paper reviews the three most common catagories of aviation accident causes and factors. The causes and factors that will be discussed are human performance, environmental, and the aircraft itself. Although flying is one of the safest means of transportation, accidents do happen. It is the investigators job to determine why the accident happened, and who or what was at fault. In the event of an accident, either one or all of these factors will be determined as the cause of the accident. Also discussed will be one of the most tradgic plane crashes in aviation history and the human factors involved.
Finally to conclude this report, the safety management system in an organization is very important as this forms the basic framework on how the organization works, maintaining safety. The four pillars (main objectives of SMA) are that ones that lead the organization in that direction. From the accident, the four pillars application will benefit the organization but however if the SMS has been a part of the organization even before, accidents as such would not have occurred in the first place.
As the first step, identify potential risks plays a crucial role in the risk management process. The core purpose of identifying risk is to figure out causes of risk and analyze result caused by the risks and its probability . Hence, risk identification can begin with the source of problem, or with the problem itself. The chosen method of identifying risk may depend on culture, industry practice and compliance. The identification
The primary cause is of airplane accidents does at some stage contain an element of a person being unable to discharge his duties correctly and in an accurate manner. More than 53% accidents are the result of ignorance or faults by the pilot during flight. Other staff is responsible for about 8% accidents. The most obvious errors by pilot are made during the take off or landing on the runway. Additionally errors can occur during the maintenance of the airplane outside the plane, whereby a lack of thorough inspection and oversight can lead to complication during mid-flight. Fueling and loading of the plane also sometimes create problems (Shapiro, 2001).
Aviation security plays a vital role in the aviation industry, from protecting passengers, staff and aircraft. The aviation industry, more specifically airports and aircraft, make prime targets for malicious harm, crime, and other threats because of the vast amount of people that use air transportation. Although there are many risks that are posed to the aviation industry, we can only hope to have learned from the history of airport bombings, hijackings, and sabotage terrorist attacks. The aviation industry faces threats at each step of the journey, but assessing the risks properly will help deter and mitigate these threats. Conducting risk analysis in today’s aviation security is not only important to the aviation industry, but it is important
Identification of the risk can simply be done by doing brainstorming with the team members. As Dr. McCarville said, there is no right or wrong answers. Every input is important and can really affect the process. Other beneficial tool is Fishbone Diagram.
A hazard is a potential damage, adverse health or harm that may effects something or someone at any conditions. Other than that, the risk may be high or low, that somebody could be harmed depending on the hazards. Risk assessment is a practice that helps to improve higher quality of the develop process and manufacturing process. It is also a step to examine the failure modes of the product in order to achieve higher standard of safety and product reliability. Unfortunately, it is common that a product safety risk assessments are not undertaken, or not carried out effectively by manufacturer. Mostly an unsafe and unreliable product was produced and launched on to the market. Thus, the safety problems are mostly identified after an accident happened or after manufacturing problems arisen. In order to prevent risk, a person should take enough precautions or should do more to prevent them because as a user should be protected from harm that usually caused by a failure for whom did not take reasonable control measures.
