This quality improvement study aims to investigate the cause of structural defects that occur during aircraft operation and to confirm structural health for the improvement configuration. Aircraft are exposed to various loads due to harsh environments and rapid maneuver during operation and mission performance. The influence of various and complex factors such as vibration, shock load, and repeated load is a potential hindrance to flight safety due to structural strength degradation and cracking compared to design load. Therefore, quality improvement is essential through inspection and cracking of vulnerable areas of the aircraft structure and analysis of structural strength, fatigue, and life. In particular, it was analyzed for defects in the structure of the landing device in which static loads and repetitive loads are concentrated during takeoff and landing. After improving the quality for defects, it was confirmed through structural strength and lifespan analysis.
