As the aircraft control surface deflection system formed by the hydraulic booster is complex, the faults of the system are difficult to be detected. It is necessary to study the control system stability and analyze the reliability in order to provide a theoretical basis for improving the reliability and security of the system. By building the booster model while considering the structural elasticity, the gap of the support structure, and the oil leakage coefficient, the effects of parametric variations for the booster model are studied based on the system stability condition. On this basis, the failure mode effect analysis and fault tree analysis are conducted to obtain the main failures and the weaknesses of the system. Then, effective measures are proposed to improve the reliability of the system in order to ensure flight safety and flying qualities of the aircraft.
