Abstract: An installation for draining liquid away from an aircraft engine compartment. Said drainage installation comprises a collector for collecting said liquid and provided with an opening putting the collector into fluid flow communication with an upstream inlet of a drainage line that is open to the outside via a downstream outlet. The drainage line includes an obstacle to the flow of the liquid that allows the liquid to flow towards the downstream outlet of the drainage line when there is a predefined quantity of liquid retained by said obstacle. The opening of the collector is provided with a firebreak grille arranged as a cap extending in elevation over the opening and including a plurality of orifices distributed at the periphery of the firebreak grille going from its base towards its top.
