In the continuous airworthiness stage of civil aircraft,risk assessment needs to be carried out to ensure that the operation safety level can be maintained within an acceptable range.Based on the transport aircraft risk assessment method(TARAM)and the risk criteria,by considering different crack sizes,the calculation method of fleet risk value is given in this paper according to the fleet fault number,critical crack and characteristic life.Taking the fatigue crack of the fuselage supercharging boundary structure as an example for ongoing safety risk assessment,the risk level of the event,and the time limit of corrective action implementation are calculated.And the implemen-tation time limit of corrective measures is validated by individual risk within time limit using corrective actions.Results show that the individual risk is below the risk threshold.It can be concluded that the corrective measures and implementation time limit formulated in this article can meet the continuous safety requirements of the fleet and thus ensure the safe operation of the fleet. |
