The increasing complexity of military aircraft systems has intensified the demand for more efficient and consistent airworthiness certification processes. In response, standardized parts—designed in accordance with international and national specifications—are being increasingly adopted to reduce redundant verification procedures and enhance the transparency and predictability of certification outcomes. This study investigates the role of standardized parts in military airworthiness certification, with an emphasis on their impact on certification processes rather than on component-level performance alone. A comparative analysis of certification frameworks in the United States, Europe, and South Korea is conducted to highlight variations in institutional structures, operational practices, and levels of digital integration. The analysis encompasses three key dimensions: technical factors related to verification reliability, organizational factors associated with documentation and data reuse, and economic factors involving testing and scheduling costs. The findings suggest that the use of standardized parts contributes significantly to minimizing redundant certification activities and facilitates the structured utilization of previously validated data. These characteristics form a practical foundation for transitioning toward digitalized certification ecosystems and for enhancing overall process efficiency in defense aerospace programs.
