The safety analysis and evaluation of civil aircraft run through the entire life cycle of the aircraft. Based on the characteristics of the operational environment and damage to civil aircraft structures, a continuous safety risk assessment process for civil aircraft structures was established based on SAE 5150. From the perspective of Probability Damage Tolerance Analysis (PDTA), the data characteristics of civil aircraft structures in the design, manufacturing, and operation stages were considered, and a probability prediction model for the structure was established using the MC method. Taking the civil aircraft keel beam crack event as an example, the safety of structural crack events was systematically evaluated, and the risk level charts were proposed that can simultaneously achieve risk level determination and determine the implementation time limit of corrective measures. Compared with the traditional risk assessment methods, the results of the determination area map based on the “Gunston” method are more accurate and intuitive.
