Root Cause Analysis of Air France Flight 447 Accident (1 June 2009)

Air accidents are extremely rare events and aviation is the safest mode of transportation. On the other hand, the risk is always present whenever any flights take place (Janic, 2000). Therefore, even identifying the main causes of one accident could be very critical for preventing future crashes that could occur at any point and any time. Therefore, the aim of this study is to investigate the root causes of one of the deadliest accidents in the history of Air France that 228 occupants including the crew and the passengers lost their lives– Accident of Air France Flight 447 in 2009. The root causes investigation started with detecting problem and the information gathered through official reports and media was examined via timeline and information mapping tools. After this step, the possible causes were investigated in terms of environmental, vehicle and human-related factors. The problems were detected as pitot tube blockage, improper actions of pilots in an emergency situation and task sharing problems of the crew. In order to find root causes behind these problems, 2 type of root cause analysis were used — 5 Why Technique and then Fish Bone Technique. The results showed that mainly human factors dominated the problems related to accident causations and there was humanrelated improper actions even behind the mechanical failures. Therefore, at the end of this analysis, it could be said that the needs of the crew should be always evaluated in detail by the organizations. Moreover, training and instructions should be clear and adequate in order to support human-machine interaction, especially during emergency situations. Lastly, hierarchical relationships could have negative effects on the appropriate behaviors of the crew members in emergency situations

Assessment of psychosocial risk factors among air traffic controllers
Altunok, Gizem; Demirel, Nuray; Department of Occupational Health and Safety (2019)
Impeccable air traffic controlling is of vital importance for air traffic management and aviation safety. Air traffic controllers, who provide advisory services to the aircraft in airspace and on the ground, usually face high level of psychological risk factors due to essence of the work. Although psychosocial risk factors among air traffic controllers have been investigated since air traffic control services were born by the first decade of the twentieth century, there is still need for further studies in ...
Improving road safety awareness through experiential learning: an action research with preschool children
Demiray Sandıraz, Betül; Ok, Ahmet; Department of Educational Sciences (2020)
Children are one of the highest risk groups in traffic injuries and casualties. All around the world, many countries try to decrease hazardous situations concerning traffic through environmental, structural, and educational adjustments. Road safety education is critical to increase awareness of children as pedestrians, bicyclists, passengers, and future vehicle drivers. The purpose of this action research is to analyze the effects of a road safety teaching unit developed by the researcher based on experient...
Investigating the effects of lightweight recycled bumper and chassis system on vehicle crashworthiness
Gürer, Batuhan; Esat, Volkan; Sustainable Environment and Energy Systems (2016-8)
Accidents are one of the main reasons of death for people across the globe, among which automobile accidents are a major portion resulting in fatalities and various injuries. Crashworthiness is an engineering concept that is used to analyse the ability of vehicle structure to cover and protect passengers in the case of an accident or impact. Crashworthiness aims to affect the design of the structure of the vehicle so that it absorbs as much energy as it can which is sustained from an impact by plastic...
Scaling for icing wind tunnel tests andvalidation with numerical simulations
Özbek Yanmaz, Gizem.; Özgen, Serkan; Department of Aerospace Engineering (2019)
Icing is one of the most dangerous hazards to be encountered by air vehicles in flight. Ice accretion, particularly on control surfaces, wings and flight data sensors usually degrades both performance and operational safety of air vehicles. Thus, it has become important in the design and certification phases of system development to evaluate performance degradation because of icing. Icing wind tunnel testing is the most convenient method considering feasibility, cost and safety. However, when full-size mode...
An Analysis of the Factors Influencing Score Achieved during Pilot Training
YAZGAN, EBRU; Cilingir, Fatma Canan; Erol, Dogan; ANAGÜN, AHMET SERMET (Japan Society for Aeronautical and Space Sciences, 2017-01-01)
Human error is considered a causal or contributory factor in a major part of aviation incidents. It's also known from relevant research and reports that even the smallest error made by a person can cause fatal results in the aviation sector. In this study, the relationship between factors that contribute to trainee error based on scores achieved in pilot training, such as personality traits, psychomotor abilities, audio-visual memory capacity and quantitative skills of pilots, are determined by means of a m...
