| Summary: | 碩士 === 中原大學 === 工業與系統工程研究所 === 106 === "Flight Safety" is the most concerned issue to the aviation industry. In the past five years, a Taiwan domestic airline had two consecutive accidents and had resulted in the closure of the company. This case shows that good safety record is an essential factor of the sustainable management to airline operation. In order to ensure the safety quality of the aviation industry, The Civil Aviation Administration (CAA) of Taiwan has regularly dispatched the designated inspectors to conduct safety inspections to airlines. These safety inspection reports could be seen as one of the safety performance indicators of each company. Therefore, in order to explore the possible use of these safety reports collected by the CAA Taiwan, we used the Human Factors Analysis and Classification System – Maintenance Audit (HFACS-MA) to analyze the probable causes inside the records. HFACS-MA is divided into four major facets: Organizational Influences, Unsafe Supervision, Preconditions for Unsafe Acts, and Unsafe Acts. The model was utilized to interpret the safety defects of different organizations, and to convert the written records into quantitative number for the further statistical analysis. We used the chi-square test and odds ratio mainly to investigate the relationship between the four levels of HFACS-MA. In short, 21 causal relationships were verified. For example, the safety oversight at the organizational level would affect the controlling/correcting of the management level, and the skill-based error of the operator. The confirmation of the causal patterns between difference levels of human factors could assist the aviation industry to eatablish a more systematic and efficient improvement plan to eliminate human errors, and would eventually enhance the safety performance of Taiwan''s aviation industry.
