PLANNING OF INSPECTION INTERVAL TO PROVIDE RELIABILITY OF FATIGUE-PRONE AIRCRAFT USING RESULT OF ACCEPTANCE FATIGUE TEST

The planning of inspection interval is considered. The purpose is to limit probability of any fatigue failure (FFP) in the fleet of N aircraft (AC) and to provide the economical effectiveness of airline (AL) under limitation of fatigue failure rate (FFR). Solution of these two problems in different previous authors’ publications has been considered. Review and some development of solutions of both problems is offered. It is based on minimax approach to processing of results of acceptance fatigue tests during which the estimate of parameters of fatigue crack growth trajectory is obtained. Numerical examples are given.
