  • 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.

  • As the majority of Korean MRO demand is outsourced overseas, AMO by major foreign authorities is required to promote the Korean MRO industry to keep Korean MRO demand on shore. This study aims to promote consulting for AMO (obtaining repair station certification) by U.S. Federal Aviation Administration (FAA) for Korean maintenance companies. We analyzed AMO process, studied various industry cases, developed a model for AMO consulting, and identified core competencies for consultants. We suggested a five-step modified Milan model to apply AMO consulting process. We identified seven core competencies (ethics, communications, problem-solving, technical, relationship, resource management, organizational understanding) both social and technical for consultants. Additionally, we text analyzed more than 260 FAA AMO consultant resumes on Linkedin and interpreted frequent words (airline, audit, inspector, DER, regulation, ISO, system) to their competencies. This study contributes to promote consulting for the Korean MRO industry to be recognized by FAA and to develop the Korean MRO industry.

  • 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.

  • 국방 무기체계의 운용유지를 위해서는 숙련자에 의한 신뢰성있는 정비 지원이 필요하다. 특히, 고도의 기술력을 바탕으로 연구/제작된 해군 무기체계를 유지하기 위해서는 이와같은 정비 지원이 무엇보다 중요하다. 해군에서는 효과적인 정비지원을 위해 수개의 정비지원부대를 조직하여 운용하고 있다. 원활한 정비지원부대의 운용을 위해 다년간 기술력을 축적한 정비인원의 중도 이탈을 예방하는 것이 요구되므로, 본 논문에서는 머신러닝을 적용하여 해군 정비지원부대의 퇴직자 예측 모델을 제안하였다. 정비인력의 만족도와 관계가 있을 것으로 예상되는 봉급, 특근율 등을 변수로 사용하였고, F1 Score를 통해 모델의 성능을 평가한 결과 0.7이상의 높은 성능을 보였다. 이 모델을 통해 조기 퇴직이 예상되는 그룹의 공통 개선소요를 파악하여 사전 조치가 가능할 것으로 판단하였다.

  • 가스터빈 핵심부품은 모두 고온고압의 열악한 환경에서 사용되므로 정기적으로 열화상태를 파악하여 신품으로의 교체 또는 재생 정비해야 한다. 그러나 국내의 재생 정비기술의 낙후로 인해 재생 가능한 고가의 부품까지 폐기, 교체함으로써 발전원가 상승의 주 요인이 되고 있다. 본 연구에서는 발전용 GT 블레이드 재료인 IN738LC 및 GTD111 판상시편에 대하여 다양한 용접 방법과 변수로 PTA 육성용접하였으며, 각 변수에 따른 미세조직 변화를 관찰하고 모의결함 시편에 대해 기계적 물성을 평가하였다.

  • The aircraft maintenance demands a lot of aviation mechanics in urgent according to the high season and low season in seasonal demand adjusted, unplanned maintenance work such as AD (airworthiness directives) and troubleshooting of aircraft system fault. The advent of Super-Large Aircraft such as A380 with aircraft materials, power plant and avionics systems which were not in previous models must be expected to increase the complexity of the aircraft maintenance system. This study is intended to propose the development plan for formation of positive flexibility culture in aircraft maintenance organization through the review of previous research on flexibility culture of organization and through empirical research for bureaucratic and poor factors by the evaluation of flexibility culture level of domestic aircraft maintenance organization.
