The invention relates to the technical field of aircraft system fault diagnosis, and provides a method and a device for detecting and handling pipeline leakage of an aircraft control surface control system. The method comprises the following steps: acquiring working data of each control surface; according to the position signal of the control surface actuator cylinder, the position values of the control surface actuator cylinder at different positions when the control surface deflects at different flight speeds are obtained, the movement speed V1 of the actuator cylinder is obtained through calculation, and a control surface actuator pressure supply pipeline flow speed monitoring model is obtained according to V1; calculating the hydraulic oil flow velocity of the pressure supply pipeline through a flow velocity model, and comparing the flow velocity with an actual flow velocity value; judging whether the pressure supply pipeline of the control surface actuator leaks or not according to the comparison result; after the pipeline leakage fault is judged, fault handling is carried out. According to the method, the defect of a control surface control system pipeline leakage fault detection means at the present stage is overcome; the method is simple to implement and simple in external field modification, realizes the detection of the leakage fault of the pressure supply pipeline endangering the flight safety, and can powerfully guarantee the flight safety.
