PASSENGER DOOR LOCK FOR DROP-DOWN STYLE DOORS ON AN AIRCRAFT
Apparatus, systems, and methods for selectively locking and unlocking a passenger door. The apparatus includes a first shaft (110) having a first longitudinal centerline (111) and a member (120) connected to the first shaft (110). A handle (130) is connected to the first shaft (110) via the member (120), the handle (130) being movable via rotation of the first shaft (110) from a locked position and an unlocked position. A first protrusion (140, 140A) extends from the handle (130) and a latch crank (160) is connected to the second shaft (150). A second protrusion (170, 170A) extends from the latch crank (160) and a linkage (180) is connected between the latch crank (160) and the member (120). When the handle (130) in the locked position, the first protrusion (140, 140A) is positioned adjacent to the second protrusion (170, 170A) to prevent rotation of the second shaft (150). When the handle (130) is in the unlocked position, the first protrusion (140, 140A) is positioned away from the second protrusion (170, 170A) to enable the second shaft (150) to rotate.
