Abstract: A latch-lock mechanism for an airplane cargo door (34) is disclosed. The latch-lock mechanism includes straight-through drive shafts rotated by a common powered drive unit (61). Affixed to the outer ends of the drive shafts are pull-in hooks (67) that co-act with pull-in pins affixed to the fuselage of the airplane adjacent to the sides of the cargo door opening. The co-action between the pull-in hooks and the pull-in pins pulls the cargo door into a closed position against a distorted fuselage cargo door opening. During opening, the co-action between the pull-in hooks and the pull-in pins force the door open against ice jams. After being pulled into a closed position, latch cams (89) rotated by the drive shafts are closed around latch pins (131). Thereafter, lock pawls (159) are moved into a closed position. The latch-lock mechanism also includes witness ports (193) located in the cargo door (34) that enable a mechanic to verify that the lock pawls (159) are in the closed position.
