The origin, the current status and existing problems of the same subject both at home and abroad in the research field of the service life of the aircraft were presented. Several key problems and their technical settlement were expounded emphatically, such as the model of corrosion fatigue of aircraft, the evaluation technique for corrosion damage of anticorrosion coats, the database of material-environment-service time and evolution law of corrosion-damage colony, the methods for theoretical analysis of the service life, the technique of nondestructive inspection (NDI) for corrosive damage and so on.
