This study examines how parts standardization policies affect the quality of airworthiness certification. While standardization enhances efficiency and compatibility, it may conflict with safety-based certification criteria. By analyzing domestic and international cases, the study reveals structural misalignments that can lead to certification delays and test inconsistencies. Key findings highlight the need for performance-based certification, standardization frameworks aligned with safety requirements, and a feedback mechanism between policy and certification processes. The proposed improvements aim to ensure both safety assurance and industrial efficiency. This research provides actionable insights for regulators and industry stakeholders in aviation safety policy.
