【 摘 要 】

CFM56-7B engine has had several ruptures of HPT blades since its service, resulting engine failure during the flight. Through borescope inspection for HPT blade can detect the damage of blade on the front and rear edge effectively, and avoid the use of damaged blades. This paper briefly summarizes the experiences of borescope inspection for HPT blade, mainly using hose to check the defect of leading edge for blade.
