| Summary: | 碩士 === 國立交通大學 === 管理學院碩士在職專班運輸物流組 === 98 === Transportation safety has served as the top concern in appraising the performance of transportation system. One got to concur that minor misbehavior is ignored oftentimes during the operation of transportation system whereas its consecutive accumulation may raise the likelihood to severe catastrophe. Some factors contributing to the occurrence of accident/incident have also been identified, including engineering design, transport vehicle design, human factor and environment factor, etc. As the consequence, it is concluded that adequate investigation, either from engineering, administration, or policy perspective, will be imperative for enhancing transportation safety.
Thanks to the speedy progress in aviation technology and also the diligent effort dedicated by professionals in aviation industry, in general aircraft system has revealed increasingly high reliability in system operation. Contrarily, odds of safety concerns suffered from human error increase constantly, as evidenced by momentous accident history wherein human error involved. According to the statistical data fostered by Aviation Safety Council (short for ASC), Executive Yuan(2009), human error stands as the top factor (96.3%) contributing to the local aircraft accident for the past ten years, in which about 74.1% can be classified as pilot related whereas the others (22.3%) be attributed to poor maintenance and inadequate airborne control. Therefore, at least in the future we may foresee, promotion and implementation of human factor study will play a progressively more crucial role in the flight safety management.
Nowadays some renowned and widely adopted human factor models are available worldwide, for instance, the SHELL and HFACS model. Among them, the HFACS model, which was developed in the States, has been confirmed as a functional tool in the investigation of flight safety events and serves as the most popular in uncovering root cause of accident and locating the relevant prevention strategy. (Wiegmann & Shappell, 2003; Li & Harris, 2005).
The Civil Aeronautics Administration (short for CAA) is authorized by the Civil Aviation Act to implement enforcement measure on the illegal findings that identified via conducting surveillance on airlines as well as their personnel. To ensure prudent and scrupulous judgment thereof, CAA has promulgated the “Principles for establishing CAA Flight safety assessment committee”, effective September 9, 1998, to serve as principal mechanism to carry out surveillance activity over the airlines. Since then the Flight Safety Assessment Committee was established and has operated over 12 years. CAA, as abide by the Article 8 of the said Principles, has continuously maintained the files relating to operation of flight safety assessment committee. Nevertheless, this precious material, mostly concerning the Civil Air transport enterprise, hitherto has seldom been surveyed.
Therefore, upon the filed records enclosing flight safety assessment events for civil transportation enterprises, in this study the HFACS model (Wiegmann & Shappell, 2003) will be implemented. This research will endeavor the evaluation for the impact of human error and, if possible, the analysis of its cause-consequence relationship to flight safety events. Furthering, effort for data-mining potential problems within airlines as well as the adequacy of their strategy for risk management will be conducted. The final outcome can afford CAA as the good reference for its discretion in flight safety surveillance.
