An intake duct assembly for an auxiliary power unit system is provided. A first inlet adapter includes at least one hole through the duct wall. A fire containment apparatus forms a first passage to direct intake air between exterior wall of the aircraft and the enclosure. An inner duct mounted on the first inlet adapter at a first position downstream of the at least one hole and mounted on the second inlet adapter. An outer sheath is mounted on the first inlet adapter at a second position upstream of the at least one hole and mounted on the second inlet adapter. The outer sheath circumscribes the inner duct to form at least a portion of a barrier annulus between the inner duct and outer sheath in fluid communication with the first passage via the at least one hole in the first inlet adapter.
