运输类飞机服役期间必须依据飞机结构腐蚀检查要求及时检查发现腐蚀，避免结构腐蚀引起飞机灾难性破坏。基于典型腐蚀环境中一种成熟运输类飞机服役期间的结构腐蚀数据，确定了运输类飞机结构腐蚀的主要影响因素和分布规律。在此基础上，根据运输类飞机适航要求，明确了飞机结构腐蚀检查要求的腐蚀检查位置和腐蚀形式、腐蚀检查方法、首次检查期限和重复检查间隔。

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.
