Keywords: airframe, reliability, bayesian analysis, corrosion fatigue

A reliability approach is applied and illustrated through a typical structural model for determining the inspection schedule and estimating the uncertain parameters. Monte Carlo simulations are adopted to demonstrate the validity of the analysis. The numerical simulation results show that the requirements for damage detection and inspection need to be more stringent for aircraft structures with corrosion effect.
