Impacto dos fatores humanos na segurança de voo em manutenção de aeronaves

Abstract

In the past, little was known about flight safety and actions for its prevention. At the 1944 Chicago convention, the Organization of International Civil Aviation (OACI), which recommended standards that would provide air transport security, being present in Brazil through decree, which aims to enact air safety nationwide. The objective of this job is to analyze how Human Factors are impacting the safety of flight within the scope of aeronautical maintenance. The study is based on the Reason, Shell Model and the Human Factors Analysis and Classification System (HFACS). Based on these studies, a survey was carried out with 29 of 31 maintainers of a maintenance hangar, which included a questionnaire elaborated through the interaction proposed by the Shell Model, with analysis and suggestions based on the Reason and HFACS Models. It is concluded that there are many factors, such as structure, fatigue, tiredness, noise, lack of motivation and supervision which often go unnoticed by the organization and can cause failures that, combined with other factors cause accidents. Actions are proposed that can help responsible bodies to act preventively in the aeronautical environment, improving increasingly this perspective that involves hard and continuous work, providing safe and orderly development in the maintenance of aircraft
