Since most aircraft accidents result in major accidents, the survival probability is lower than in other transportation. The Coast Guard aviation is developing gradually. In the case of Korea, which is surrounded by sea on three sides, rapid response and search and rescue activities with guard ships are limited due to geographical conditions. To overcome these limitations, a rapid response is needed above all else. In this way, search and rescue agencies cannot be ruled out to use aircraft with excellent mobility on the sea and to conduct rapid rescue operations in the event of an incident. Aircraft are equipment that flies in the sky and require stricter safety management controls and regulations than equipment that operates on the ground. Therefore, the purpose of this study is to identify aviation safety problems caused by the difficulty of flight missions of the Coast Guard aviation organization and operation of multiple aircraft types and suggest improvement measures. Research methods mainly included literature review, identification of the safety status of Coast Guard aviation, and comparison methods with other organizations. As an improvement plan, first, we propose a management plan for aircraft operation quality and maintenance quality, second, we propose a reorganization of the organizational structure and personnel necessary for aircraft safety management and supervision, and third, we propose a plan to reorganize the safety analysis office.
