ResumoStatistial investigation for corrosion damage of aircraft structure has been conducted by four probability distribution function.The result show that the maximum corrosion depth for aluminum alloy in the service environment is in conformity three parameters Weibull distribution and it was good agreement with the corrosion damage cumulation law.Statistical tests of the distributions are conveniently made by the Pearson statistical parameter—linear relationship coefficient r .Critical value of the r for an accepted distribution is determined by a transformation of r-to-t distribution function.The location parameter of Weibull distribution was obtained by relative coefficient optimization method.
