The rapid development of Electric Vertical Take Off and Landing (eVTOL) aircraft is transforming urban aviation, introducing new challenges for airworthiness certification an essential process to ensure operational safety and regulatory compliance. This paper presents a Type Certification framework for eVTOL aircraft, leveraging the Arcadia Model-Based Systems Engineering (MBSE) approach through the Capella tool. This framework replaces traditional document-based methods with a model-driven approach that integrates regulatory standards and Means of Compliance (MoCs) into a unified system model. Additionally, automation is introduced through Large Language Models (LLMs) to dynamically predict and validate MoCs from textual requirements, streamlining checklist generation and enabling rapid adaptation to evolving regulations. While the framework improves efficiency, it complements rather than replaces expert supervision, emphasizing the importance of human oversight in complex regulatory contexts. The proposed framework is scalable and adaptable, applicable not only to various eVTOL platforms but also to other emerging aircraft types. Findings from case studies and expert evaluations demonstrate a significant reduction in workload, enabling faster certification while maintaining accuracy and regulatory alignment. This study offers a replicable, efficient model for certification that fosters the adoption of emerging technologies while ensuring high safety standards and supporting sustainable growth in urban air mobility.
