A decompression panel assembly for use in an aircraft includes a frame including a first surface and an opposing second surface, wherein the frame defines a grille opening and at least partially defines a flow path opening that are each defined between the first and second surfaces. The decompression panel assembly also includes a first panel and a second panel pivotally coupled together at a central hinge. A retention plate is releasably coupled to the first and second panels and is configured to move between a closed position and an open position. The first and second panels at least partially cover the grille opening in a planar position when the retention plate is in the closed position, and the first and second panels move away from the grille opening to a folded position when the retention plate is in the open position.
