Abstract: There is provided a method of and system for forecasting maintenance operations to be applied to an aircraft engine including a plurality of components monitored by damage counters, each damage counter being limited by a corresponding damage ceiling, the method including simulating consumption of the damage counters by iteratively drawing a series of simulation missions from a learning database; for each iteration, determining an accumulated consumption of each of the damage counters, until at least one damage counter related to a current simulation mission reaches a predetermined value limited by the damage ceiling associated with the damage counter; and applying a maintenance strategy on the current simulation mission to determine maintenance indicators representative of maintenance operations to be planned on the aircraft engine.
