Abstract�� In order to estimate fatigue life of aircraft structures under corrosive environment, a nominal stress approach under corrosive condition (Cor-NSA) was developed. Based on the curve of parking corrosion influence factor (C) versus parking time (T),��p-S-N�� curves for the critical part of an aircraft component can be determined by inverse computation method, corresponding to different parking years. Thus, the fatigue safe life of aircraft structures under service environment could be predicted according to Miner's law. Furthermore, the life should be modified with flight corrosion influence considered. Finally, an example was given to show the validity of the method.
