【 摘 要 】

While aeronautical technology has been developing continuously in recent years, aviation accidents can never be completely eliminated. According to statistics, the actual risk of engine control system is often higher than risk expected in the design stage, which does harm to aviation safety. Therefore, a probability risk assessment method of engine control system is proposed, in which bottom faults, loss of thrust control (LOTC) events and serious consequence of aircraft are all evaluated. At last, the validity and practicability of this method are verified by the example of the failure risk analysis and control of VSV actuator in CFM56-7B engine. This paper provides a reference for risk management of engine control system in the stage of continued airworthiness.
