The Fatigue Crack Growth (FCG) requires the monitoring of the evolution of the length of the crack during the lifespan of the component. Maintenance inspections are needed to ensure the survival of the component. Depending on the inspections results a maintenance policy is implemented. Based on an economic study and using a dynamic method the optimal time is determined for a single and two inspections. Generalization of this method is presented for the multiple inspections. In order to illustrate and validate this method two applications are carried out: the first one is general and the second one is applied to the crack growth in mixed mode.
