Abstract

Switching to double inspection frequency after first fatigue crack discovery during aircraft inspection in operation is investigated. The method of calculation of the probability of fatigue failure based on the use of Markov chains theory is offered. For inspection program development on a base of lifetime approval test result processing the use of p-set function and minimax approach is offered. In this case there is no necessity to look for dubious compromise choice of required reliability and confidence probability.
