Analyzing Human-caused Accidents in Aviation Maintenance - Focusing on SHELL Model

Whether aircraft accidents are caused by mechanical defects or human factors, the consequences are fatal to human life and property, which makes it critical to eliminate the causes and develop preventive measures. The research on human factors in aviation accident has been mainly conducted in relation to flight crews and then expanded into the field of aviation maintenance since the early 1990s. The basic concept of aeronautical maintenance is to maintain airworthiness in order to ensure the safety of the aircraft by perfect operation and service of all aircraft systems. This research studies on the theoretical background of human factors in the aviation field and examines the analytic model for the cause of aircraft accidents. In addition, it analyzes some cases which called attention to human factors in aircraft maintenance based on the ‘SHELL Model’, which is recognized as the basic theory of human factors in the aviation field.
