Abstract
A stair and stairwell construction for interconnecting two different decks, especially in an aircraft, includes stair treads, stringers, and a stairwell enclosure or housing. At least one of the just enumerated components is constructed to be positionable or tiltable relative to the planes defined by the decks. One of these components is positionable into an open position, thereby providing a passageway, or into a closed position thereby blocking the passageway. In both positions, this positionable component is lockable.
