Airline Maintenance Quality Management Standardization

Outsourced maintenance is expanding among Korean airlines, alongside in-house work with domestic and overseas AMOs. This trend heightens the need to align responsibility and authority for continuing airworthiness. This study proposes a standardized quality-management framework for outsourced maintenance tailored to the domestic context. The framework is derived from a comparative reading of FAA and EASA provisions and IATA model terms. Its organizing spine is the AOC’s life-cycle authority: pre-contract due diligence and competency checks, in-process stop- work and change approval, and post-work acceptance with records review. It prescribes consistent documentation across internal manuals, contracts, and oversight guidance. The framework supports credible discharge of continuing-airworthiness responsibility as outsourcing grows.
