Abstract: An aircraft door lock having a bolt and a closure block, wherein the bolt is fastened in a movable manner to a door leaf structure and the closure block can at least partially receive the bolt. The closure block prevents any movement of the bolt in at least one direction, wherein the closure block is arranged on a portion of a hinge arm that overlaps the door leaf structure when the door leaf structure is in a closed position. Furthermore, an aircraft door having such an aircraft door lock, and an aircraft having such an aircraft door are described.
