AVIATION SAFETY CULTURE MEASUREMENT MODEL FIT VALIDATION OF A SURVEY FOR THE AVIATION MAINTENANCE REPAIR ORGANIZATIONS

It is believed that safety is the major issue for the aviation industry. According to Boeing Study %15 of the fatal accidents are incurred by maintenance sources related. On the other hand, from the last ten years safety management system which firstly introduced by ICAO became popular in the aviation industry. In the beginning, enforcement by ICAO Annex 19 then following it consequtively by EASA’s regulation, at the same time issued many advisory circulars by FAA that SMS entried in force and still other authorities are acting by similar way. However, the most important element of the SMS is based on properly establishment of safety culture in organization. Up to now there are many methods introduced in the literature for measuring safety culture of aviation organizations. Even though an aviation company may select one model as to another one for measuring own safety culture, but they are not sure whether this model run perfectly and reflect true results or not. In this study it is aimed to bring out how the proposed ECAST’s safety culture model which is compliance for the aviation maintenance organizations by validating Structural Equation Modelling.
