Abstract: To do Corrosion Fatigue tests and analyses of typical Components of aircraft,the Compilation of aircraft. In this Paper the Concept and Classification of aircraft load-environ- ment spectra are stated and compiling method of the spectra put out.Compiling procedure of aircraft equivalent environment spectra is mentioned.The equivalent environment spectra and the load-environment spectra of N5A aircraft have been compiled.The method is of general usage and engineering application,and can be used for compiling equivalent environment and load-en- vironment spectra of different type aircraft.

Key words: corrosionenvironmental models, aiveraft specification
