This study investigates the effectiveness of Key Performance Indicator (KPI)-driven strategies in aviation maintenance, specifically within Continuing Airworthiness Management Organizations (CAMO). As the aviation industry evolves, CAMOs are increasingly shifting from traditional, reactive maintenance approaches to more proactive, data-driven methods centered around KPIs. This research explores the adoption of KPI-based maintenance strategies, assessing their influence on operational efficiency, regulatory compliance, and overall maintenance performance. Utilizing a mixed-methods research design that combines quantitative data analysis with qualitative insights from industry professionals, the study highlights significant enhancements in maintenance outcomes attributable to the strategic use of KPIs. Advanced analytics enable CAMOs to better predict maintenance needs, optimize resource allocation, and reduce downtime, thereby improving safety and cost-effectiveness. Despite these benefits, the research also identifies challenges related to data integration, organizational change management, and regulatory alignment that must be addressed to fully leverage KPI-driven practices. The study concludes with practical recommendations for aviation maintenance managers aiming to optimize their CAMO operations through targeted KPI implementation. Additionally, it outlines promising directions for future research, including the integration of emerging technologies such as artificial intelligence and machine learning to further refine predictive maintenance strategies and enhance the safety and reliability of aviation operations.
