  • The need for risk based safety management has been highlighted in accordance with the growth of aviation industry and public interest in aviation safety. Maintenance, Repair and Overhaul (MRO) in aviation industry is defined to guarantee the safety and reliability. Therefore, state's Civil Airworthiness Authority (CAA) has established safety oversight system dedicated for the development of a healthy MRO industry. The study proposed a risk based oversight system considering Korean environment. Based on literature review including analysis of International Civil Aviation Organization guidance and advance system, we identified two organization risks. Organization complexity can be evaluated in accordance with how large the organization is and how complicated the service they provide are. Organization profile is the organization's characteristic related with safety. This study contributes to improving the process of identifying risk of organization and focusing surveillance capabilities on risk areas for efficient management of CAA's resources.

  • 우리나라 양계업도 기초단계에서 발전단계를 거쳐 완전한 한 개의 산업으로서 정립할 단계에 와있다. 모든 산업이 다 이런 과정을 거처 도약하고 있으니 양계산업도 예외는 될 수 없을 것이다. 다시 말하면 정비상완기에 돌입하였다는 말이요 만약 촌시라도 정비보완을 게을리 한다면 차기도약은 불가망일 것이며 아깝게도 우리의 땀과 열성으로 길러온 양계업은 빛도 못 본체 고사하고 마는 중대한 전환기라 하겠다. 보라!(중략)

  • The marine transport industry generally applies new technologies later than other transport industries, such as airways and railways. Vessels require efficient operation, and their performance and lifespan depend on the level of maintenance and management. Many studies have shown that corrective maintenance (CM) and time-based maintenance (TBM) have restrictions with respect to enabling efficient maintenance of workload and cost to improve operational efficiency. Predictive maintenance (PdM) is an advanced technology that allows monitoring the condition and performance of a target machine to predict its time of failure and helps maintain the key machinery in optimal working conditions at all times. This study presents the development of a marine predictive maintenance (MPdM; maritime predictive maintenance) method based on applying PdM to the marine environment. The MPdM scheme is designed by considering the special environment of the marine transport industry and the extreme marine conditions. Further, results of the study elaborates upon the concept of MPdM and its necessity to advancing marine transportation in the future.

  • The International Civil Aviation Organization (ICAO) in 2015 proposed a road-map for the global recognition system of the Approved Maintenance Organization (AMO) fto mitigate the redundant work and regulatory burdens of the aviation industry and authorities on the certification and oversight activities of the State of Registry. Since then, the ICAO standards and guidelines have been revised accordingly with the goal of implementing the system in 2024. Korea should actively prepare for this AMO global recognition system to cope with the ICAO road-map appropriately as well as to develop the Maintenance Repair Overhaul (MRO) industry. Thus, this paper focused on the ratings and limitations system, a key element of the AMO, and proposes the improvement of domestic regulatory/administrative rules necessary for the global recognition system, through the review of newly established ICAO standards/guidelines and the comparative analysis of leading aviation countries' and Korean system/requirements.
