建立了民用运输类飞机持续适航阶段的风险评估方法,给出了事件风险类型的分类、事件后果严重度等级的划分、事件概率水平的确定方法,通过风险矩阵和冈斯顿方法分别确定事件风险水平和高风险事件纠正措施的实施时间。采用所建立的风险评估方法对某型飞机机翼油箱超压损坏的危险事件进行了风险评估,确定了该事件的风险水平,给出了适当的纠正措施。
The risk assessment approach for the civil transport category airplanes during continued airworthiness has been established in the present analysis. The risk types of the event, the severity level of the event consequence and the approach to determine the probability level of the event have been given. The risk matrix method and the Gunstone method were used to determine the risk levels and the time of appropriate corrective actions. The risk assessment of wing fuel tank overpressure damage event of a certain airplane was analyzed using the present approach. The risk level of the event was determined and appropriate corrective actions were also given.
