A method for balancing an aircraft turbofan engine using a respective artificial neural network for each flight of multiple reference aircraft to predict the engine vibrations that would be produced in response to input of flight parameter and balance weight data acquired from a flight of a test aircraft of the same type. The resulting sets of predicted vibrations are then processed to identify and collect those engine vibration predictions which match or nearly match the engine vibration measurements acquired from the test aircraft during its flight test. For each matching modeled flight of the reference aircraft, the magnitude and phase angle of the mass vector for any commonly used balance weight configurations are determined and included in a list of recommended balance weight configurations. A technician can then reconfigure the balance weights attached to the engine on the test aircraft in accordance with a selected recommendation.
