The article describes the stages of "life cycle" of aircraft in conjunction with external factor-tors that affect the reliability of aircraft. The mechanisms of changes in physical and mechanical properties of materials by degradation processes during prolonged use. Based on Markov Model Theoretical analysis of changes in the technical data of the state for the contacts-tual sacristy potential.
life cycle Markov model, the contact potential difference, the fatigue of structural materials
