An aircraft latch is disclosed for latching to the preexisting latch pin of an aircraft assembly. The latch includes a trigger safety to block the trigger from accidentally being opened. A link trunion adds rigidity to the system and cooperates with the trigger safety to provide an anti-vibrating feature. A detent on the latch cooperates with the installation housing in which the latch pin is mounted to hold the latch handle in place when the latch is fully opened to prevent the aircraft doors in which the latch is mounted from being closed inadvertently while the latch is still unlatched.

Aircraft latch

Disclosed is an increased strength dogging mechanism operable by a handle for releasably securing a door on each side of the door to a structure. The dogging mechanism includes a plurality of dog keepers each having a ramp portion and a seating portion mounted to each side of the door. A dog having a roller is rotatably mounted to engage a cooperatively associated dog keeper. A mounting bolt extends through the structure and through the approximate center of each dog. A drive assembly which is movable by the handle between open and closed positions moves each dog, simultaneously, between unlocked and locked positions. As the dog is rotated to the locked position, the roller of each dog engages the ramp portion of its associated dog keeper and rolls upon the ramp and into the seating portion. The action of the dogs rolling upon the ramps of the dog keepers on each side of the door moves the door perpendicularly into the structure compressing a seal and rigidly secures the door on all sides to the structure to form a waterproof enclosure.
