항공기 연료 결함으로 인한 사고는 CICTT에서 규정하는 사고유형 34개 중 상위 13번째를 차지할 정도로 중요하다. 유통과정과 보관환경 등에 따라 수분이나 오염물질의 유입되어 항공기 사고가 발생하는 것으로 알려져 있다. 장기간 보관 항공유의 물성변화를 확인 하고자 JET A-1 항공유를 금속캔에 보관하여 6개월 이후의 변화를 관찰하였다. 그 결과 장기간 보관된 항공유는 품질기준을 만족하였으 며, 연료유의 안정성도 높은 것으로 확인되었다. 하지만 해양경찰 항공기와 같이 임무의 특성상 항공유를 선박과 육상 저장시설, 유조차 등에 분리하여 보관하고 있는 상황에서는 내외부 환경 변화로 인해 수분이나 오염물질의 유입 가능성이 높다. 또한, 오염물질에 대한 분 석은 현존 검, 증류성상 등으로 분석이 가능하지만 수분의 경우는 국내외 표준과 국내법령에서 물 분리지수를 통한 항공유의 수분 분리 능력을 판단할 뿐 수분함량에 대한 분석이 수행되지 않고 있다. 이에 수분함량에 대한 품질관리 기준을 추가하고 국내외 표준과 법령을 획일화하는 개정을 수행하여 항공 안전성을 확보해야 할 것이다.
The major issue in aircraft industry is aviation safety management because of demand improvement and advancement of the aircraft. This study is to assess the risks for aviation safety management using IRPN( importance-risk priority number) which is added to importance coefficient from RPN(risk priority number). In FMEA, RPN requires the factors like the occurrence (O), Severity (S), and Detection (D) of each failure mode to be precisely evaluated. Therefore, the severity and detection is derived by the value from FMEA of expert group based on the Fuzzy theory. The occurrence is calculated from the accident statistics of IATA(international air transport association) database. Particularly, this study introduces importance coefficient to prevent from RPN distortions. It is also derived from FMEA based on the Fuzzy theory. Finally, the critical ranking of risk factors according to I-RPN is compared with the existing research.
The goal of this paper is to suggest aircraft maintenance and its improvement for aviation safety. The purpose of aviation safety is to prevent aviation accidents resulting in damage to human life and property. Aviation safety relies heavily on maintenance. Human error is cited as a major causal factor in most aviation mishaps, including maintenance error. Errors can be described as active failures that lead directly to the incident, and latent failures whose presence provokes the active failure. Maintenance errors are parts installed incorrectly, missing parts, and necessary checks not being performed. In comparison to many other threats to aviation safety, the mistakes of an aviation maintenance technician(AMT) can be more difficult to detect. Often times, these mistakes are present but not visible and have the potential to remain latent, affecting the safe operation of aircraft for longer periods of time. State safety programmes is a system of activities for the aim of strengthening the safety and integrated management of the activities of government by standards of the ICAO. In summary, It is necessary to revise regulations on the basis of the aviation practice for aviation safety regulatory requirements. The goverment will eventually need to promulgate fatigue management standsrds for AMT also pay particular attention to the safety and education for small aircraft AMT.
The Chicago Convention in 1944 made important contributions to aviation safety improvement, building an aviation safety monitoring system for its signatory countries. As ICAO is now on the verge of changing its supervision system from self-reporting to preventive Continuous Monitoring Approach(CMA) in 2013, we also expect our own safety system to make a progress accordingly. The government is pushing ahead with plans to build an integrated safety management system at government level that satisfies international standards and reflects domestic features. To this end, this report proposes the most effective system-building model, by analyzing the current status of the system that is in use and meets the requirements of international aviation agencies.
Purpose - In this study, the safety related tasks for low cost carriers’ were examined and measures to improve them were suggested. As the air demand increases rapidly, number of passenger has mushroomed in Korea and in order to keep with the demand low cost carriers have played a role. However, low cost carriers’ safety related tasks are not reliable level so far. Thus, in this study, the low cost carriers’ current situations in terms of safety are investigated, especially regarding how well the ICAO’s new safety policies are applied.
Research design, data, and methodology - The results of the Ministry of Land, Infrastructure and Transportation’ investigation are introduced and field study results are analysed. Current status of retaining experts, staffs, administrators in terms of aviation safety tasks of low cost carriers is compared to those of major airliner and low cost carriers’ aviation safety culture is also analyzed by examining the systems and questioning staffs. Especially the culture regarding aviation safety is very important because the culture surrounding the safety tasks plays a major role in every respect of conducting the tasks.
Results – Overall the current status of low cost carriers’ aviation safety tasks is below standard. Especially retaining experts and staffs is basically below the required level. Also, system and organization to conduct safety tasks are not satisfactory. In particular, aviation safety culture is not settled to operate appropriately.
Conclusions - The International Civil Aviation Organization (ICAO) and member states are continuing to launch new safety policies in response to the surging demand for air travel worldwide. The most urgent and important issue among the various safety policies is to reduce air accidents. In order to reduce the number of accidents, ICAO decided to reduce the number of accidents by using the Reactive Safety Management. ICAO has to ensure that each member country can implement proactive safety management for aviation safety. A safety management system (Safety Management System) is a system in which each member state implements a fulfillment standard. The current situation and problems of the safety management system for each airline are suggested and proposed for improvements.
