The present invention relates to a method for modifying an aeroservoelastic figure analysis model with flight test analysis data and a device thereof. The method for modifying the aeroservoelastic figure analysis model comprises a step for calculating the gain margin of the figure analysis model by analyzing the figure analysis model for an aircraft having a predetermined armed shape, a system, and a control mode; a step for obtaining the flight test analysis data by performing a flight test for the aircraft and calculating the gain margin of the flight test analysis data; a step for comparing the gain margin of the figure analysis model analysis result with the gain margin of the flight test analysis data; and a step for modifying a decrease figure of the figure analysis model in order that the difference calculated in a part which shows a comparison result structure vibration mode is under a setting value. The present invention is provided to confirm conservatism of an existing figure analysis model by comparing the figure model with the flight test analysis data, thereby modifying the decrease value and improving the accuracy and reliability of the figure analysis model.
