A method for controlling a multi-engine bay (10), according to which the following steps are carried out: a) the bay is controlled so that it ensures a desired thrust and so that each engine is used in accordance with a set of operating limits for the engine; b) damage (ENDO) of each of the engines is evaluated periodically, the damage to an engine being a piece of information representing a probability of failure of the engine; c) for each engine, it is periodically evaluated whether its damage (ENDO) exceeds a predetermined value (ENDO_S); and d) if the damage to an engine, referred to as the damaged engine, exceeds a predetermined value, at least one operating limitation of the damaged engine is modified so that the rate of damaging of the damaged engine (dENDO/dt) is less than a predetermined maximum rate of engine damaging (dENDO/dt_max). Control system for a multi-engine bay and multi-engine bay allowing the implementation of the method.
