SUMMARY
In Indonesia, the rate of accident and serious incident of aircraft have reached alarming stage. National Transportation Safety Committee affirmed that human errors played the biggest role from period 2007 – 2013. Although there are several possible causes for human error, one of the most critical elements is the quality of Aircraft Maintenance Organization, especially the human resources.To get basic knowledge of human factor, the first step of this study is literature study. The literature reviews showed that there are at least four factors that influenced human errors. They are Organizational Design, Safety Climate, Safety Performance, and Safety Outcome. After the factors were discovered, the next step is choosing the methodology. Since most of the literatures used models to describe the situation, this study will use similar approaches. Ostroff et al Model (2003) and Christian et al Model (2009) are chosen among the model because they can represent the most accurate situations in Aircraft Maintenance Organization in Indonesia. To get an added value, after these two model are merged, Principle of Hoffman (2003) is used to give a better and upgraded model. The proposed model is then explained through six proposed hypotheses, in which two of them are the added values. To collect the suitable data for the model, the final step is deciding the operational variables which are described on the form of tables for each factor. Each variable is tested through sub-model. Method used for gathering data is questionnaire which uses Likert scale test. The result of Likert scale test and the sub-models will become the proposed model. The proposed model is expected to give Aircraft Maintenance Organization a better understanding on human error and make them focus their improvement on human factor more so that the rate of accidents and serious incidents in Indonesia can be reduced significantly.
