FIELD: control; regulation.SUBSTANCE: invention concerns a method and system for forecasting maintenance operations to be applied to an aircraft engine comprising a plurality of elements monitored by damage counters, each damage counter being limited by a corresponding damage ceiling. This system comprises processing means (7) suitable for simulating a consumption of said damage counters (C1-Cm) by iteratively pulling a series of simulation missions from a learning database (9) containing test missions, processing means (7) suitable for determining, at each iteration, an accumulation of consumption of each of said damage counters until at least one counter counting damage related to a current simulation mission reaches the damage ceiling associated with same, and processing means (7) suitable for applying a maintenance strategy to said current simulation mission to determine maintenance indicators representative of the maintenance operations to be planned on the aircraft engine.EFFECT: maintenance operations
