This paper develops a conceptual framework to examine the relationship between Supply Chain Management (SCM) strategies, SCM capabilities, and the sustainability of aviation ground maintenance operations. It highlights how SCM strategies can significantly enhance operational sustainability when mediated by SCM capabilities such as coordination, information exchange, integration, and responsiveness. The study synthesizes insights from existing literature to propose how strategic management of supply chains can lead to improved sustainability outcomes in the aviation industry. The framework suggests that integrating advanced SCM strategies with robust capabilities is essential for ensuring efficiency, compliance, and environmental stewardship within aviation maintenance operations. This research contributes to the academic discourse on supply chain sustainability by providing a structured framework that can serve as a foundation for future empirical research.
