A door assembly, particularly for doors of passenger aircraft, includes a door frame, a door having a door body hingedly installed in the door frame, at least one door latch (2) connected to an edge of the door body or the door frame, the door latch (2) having a latch fulcrum (2a) and a latch lever (2b) and being configured to pivot around a pivot axis around the latch fulcrum (2a) running parallel to the edge of the door body, and at least one hook member (3) attached to the door frame or the edge of the door body, respectively, the hook member (3) being configured to catch the door latch (2) in hooking engagement, to retain the door latch (2) in a direction perpendicular to the door body and to allow pivoting movement of the door latch (2) out of the hooking engagement around the pivot axis. A bistable latch linkage (7b) is hingedly connecting the latch lever (2b) to the door body or the door frame. The bistable latch linkage (7b) may take on a spring-actuated overcenter position in which the pivoting movement of the door latch (2) out of the hooking engagement with the hook member (3) is blocked and a deadcenter position in which the latch lever (2b) is pivoted in an opposite direction to the pivoting movement of the door latch (2) out of the hooking engagement with the hook member (3), thereby moving the door initially against its opening direction.
