The invention provides a safety assessment method for a light structure of an aircraft, belongs to the technical field of aerospace, and solves the problem that the safety assessment capability of the light structure of the aircraft is insufficient at present. The method comprises the following steps: S1, aiming at the safety problem of the light structure of the aircraft, identifying and determining key factors influencing the response of the light structure; s2, designing a simulation experiment simulation criterion and implementing a simulation experiment for analyzing the influence degree of the key factors on the safety of the lightweight structure of the aircraft; s3, testing the response of the light structure of the aircraft in a wind tunnel experiment environment, and obtaining safety evaluation data reflecting the light structure of the aircraft in an actual operation environment; s4, combining the influence degree obtained by the simulation experiment with the safety evaluation data obtained by the
