In order to verify the influence of environment on xx aircraft life, local environment spectrum of typical parts was developed based on the analysis of structural of typical corrosive fatigue components of XX aircraft and corrosive environment. Through the linear fitting and computation, the conversion relationship between the environment spectrum for local parking and the lab acceleration environment was established according to the equivalent acceleration principle, and has been successfully applied to the life extension of xx aircraft. It verified an important effect on aircraft life and supplied a reference on aircraft operation maintenance.
