中文摘要：

随着轻型飞机的大量使用，其可靠性和和可用性不断面临新的挑战。因此，轻型飞机的健康管理与预测（PHM）技术显得日益重要，它不仅能够保证飞行安全，同时也可以降低使用成本、合理安排维修计划。针对目前尚未成熟的PHM技术，本文首先对轻型飞机PHM系统的框架以及受益进行了分析。其次，讨论了轻型飞机PHM系统设计与分析中的关键问题。最后，阐述了轻型飞机PHM技术应用的关键技术难题以及未来发展方向。

英文摘要：

To face new challenges appearing in reliability and availability of more and more light aircraft, Prognostics and Health Management （PHM） is proposed and shows great power in guiding maintenance plan and cutting related costs. However, the aviation application of PHM is still immature until now. In this paper, some important points on light aircraft PHM are discussed. Firstly, framework, architecture and benefit tbr light aircraft PHM is analyzed. Then, the key design and analysis problems of light aircraft PHM system are reviewed. Finally, the anticipated challenges and future direction are provided, suggesting those areas in which further improvements are necessary.
