Abstract: A stair closure mechanism is disclosed. In embodiments, the stair closure mechanism is attached to and deploys in concert with a door separating an overhead crew rest compartment and access stairway from the main cabin. As the door is closed, a closure panel mechanically pivots with the closing of the door into a horizontal deployed position. When in the deployed position, the closure panel conforms to the floor of the overhead compartment, securely blocking the free space between the stairway and the floor from persons in the overhead compartment who might otherwise step or stumble thereinto.

Abstract: A cart bay for an aircraft galley structure includes a housing defined by interior surfaces and capable of housing one or more removable galley carts in a secured position. Chilled air is introduced into the cart bay through a plenum of inlet to maintain perishable contents of the galley cart at a safe temperature. The side walls of the cart bay include rubstrip assemblies for guiding the galley carts in and out of the bay, absorbing impact and noise. The rubstrip assemblies may include a corrugated carrier layer behind a solid rubstrip; the corrugated carrier layer includes apertures for controlling and directing the flow of chilled air along the side walls to maximize the exterior surfaces of the galley carts reachable by the chilled air, separating the galley carts from the side walls and allowing chilled air to reach the side exterior surfaces of the galley carts via the apertures.
