Civil aircraft may encounter icy conditions on the ground or during flight, such as freezing fog, rain, and snow. Icing may cause deformation of typical aircraft mechanisms and cause damage or blockage, which is an essential factor that threatens the safety of civil aviation operations. In order to analyze the failure evolution process of civil aircraft doors, the performance of civil aircraft doors is analyzed with time based on the experimental data of cabin doors under freezing conditions. The evolution process of failure of civil aircraft doors is studied to provide support for improving the safety and environmental adaptability design of civil aircraft doors.
