As outsourced maintenance in civil aviation expands, the allocation of safety management responsibilities between air carriers and maintenance organizations has become an important legal issue. This study examines the legal structure of outsourced maintenance contracts and the distribution of safety responsibilities through a comparative review of ICAO standards, IATA guidance, the FAA’s oversight approach, and the Korean aviation safety legal framework. The findings show that the Korean system includes key control elements for outsourced maintenance, but they remain dispersed across regulations and certification requirements. Accordingly, the air carrier’s safety oversight authority is not clearly defined. This study argues that the issue should be addressed not by granting comprehensive control, but by clarifying a functional and limited safety oversight authority necessary to ensure continuing airworthiness and safe operations.
