Abstract

The control system of the invention includes at least one actuator (6) for a cowling (2), driven by at least one electric motor (7), and control means (9) for the electric motor (7) and the actuator (6). The control system includes an electric circuit (C) that comprises: a plurality of electric components; a plurality of measuring means (16-18) adapted for measuring respectively a characteristic magnitude of an electric component or a group of electric components in the electric circuit; a failure detection means (19) adapted for detecting a failure at a component of the electric circuit when the characteristic magnitude measured at said component exceeds a predetermined value or is in a range of predetermined values.
