Inspection Requirements for Structure Corrosion of Transport Aircraft

During the service of transport aircraft, corrosion must be checked in time according to the requirements of aircraft structure corrosion inspection to avoid catastrophic damage caused by structure corrosion. Based on the structure corrosion data during the service of a type of mature transport aircraft in a typical corrosive environment, the main influencing factors and distribution rules of the structure corrosion of the transport aircraft were determined. According to the airworthiness requirements of transport aircraft, the corrosion inspection position, corrosion inspection mode, corrosion inspection method, first inspection period and repeated inspection interval were defined.
