A fireproof assembly for an aircraft engine, comprises a fireproof housing having an internal volume and an opening. A fireproof internal shield is located within the fireproof housing. The internal shield divides the volume into a first sub-volume and a second sub-volume, the first sub-volume configured for receiving a component of the aircraft engine. A non-fireproof component seals the opening of the fireproof housing. Fireproof fasteners are used to support internal shield inside the housing.
