A sealant containment assembly is configured to bound at least a portion of a fastener pattern between at least two components, such as components used to form at least a portion of an aircraft. The sealant containment assembly includes at least one sealant containment member that is configured to sealingly engage peripheral portions of components. The sealant containment member(s) is configured to form a sealing chamber around at least a portion of the fastener pattern. Fluid sealant is configured to flow into the sealing chamber and cure to seal fasteners within the fastener pattern that connect the components together.

An object transfer system ('OTS') for a flight of steps for transporting an object on the flight of steps is disclosed. The OTS may include a rail positioned in place of a handrail on the flight of steps, a trolley assembly movably attached to the rail, and an object carrier attached to the trolley assembly. The rail has a rail length and the object carrier is configured to hold the object. Additionally, the trolley assembly is configured to transport the object held by the object carrier along the rail length.
