In an example, a system is described. The system includes a guardrail having a post, and the post having a post dog. The system also includes a latch eye configured to be coupled to a flip door. The system also comprises a safety latch mechanism configured to be coupled to a fixed structure and including a body, a socket configured to receive the post, and a door latch rotatably coupled to the body and biased in a latched position that is configured to engage with the latch eye and thereby retain the flip door in a lowered position. Based on the post being inserted into the socket of the safety latch mechanism, the post dog engages with and rotates the door latch from the latched position to an unlatched position, thereby allowing the flip door to be raised from the lowered position to a raised position.

Inboard-mounted safety latch mechanism for preventing a walkway platform flip door from being raised without a guardrail installed

In an example, a system for preventing a flip door from being raised without a guardrail installed is disclosed. The system includes a guardrail having a post, and the post having a post dog. The system also includes a safety latch mechanism configured to be coupled to a fixed structure. The safety latch mechanism includes a body, a socket disposed in the body and configured to receive the post, and a door latch rotatably coupled to the body and biased in a latched position that is configured to retain a flip door in a lowered position. Based on the post being inserted into the socket of the safety latch mechanism, the post dog engages with and rotates the door latch from the latched position to an unlatched position, thereby allowing the flip door to be raised from the lowered position to a raised position.

Methods and systems for assembling containerized aircraft as complete aircraft. The methods comprise removing aircraft components from shipping container(s), unloading the aircraft components from shipping fixture(s), removing tooling comprising aircraft component positioning structure(s) from the shipping container(s), loading aircraft component(s) onto aircraft component positioning structure(s), positioning the aircraft components in aircraft component installation positions, positioning the aircraft component(s) using the aircraft component positioning structure(s), and attaching the aircraft components to assemble the complete aircraft. The systems comprise aircraft components configured to be loaded into shipping container(s) in a shipping arrangement, unloaded from the shipping arrangement and attached to at least one other aircraft component to assemble the complete aircraft; shipping fixture(s) configured to support the aircraft components in the shipping arrangement, and tooling configured to facilitate assembly of the aircraft components and comprising aircraft component positioning structure(s) configured to position aircraft component(s) in aircraft component installation position(s).

A method and system for alleviating a load is provided. A support system is positioned at a nominal location with respect to an object. The support system comprises jacks and supports. Each of the supports is associated with one of the jacks. The object is positioned on the support system. The support system with the object is moved across a path. The height of each of the jacks is adjusted as the support system moves along the path to maintain a desired minimum load on each jack. Maintaining the desired minimum load prevents damage to the object.

Method and system for load alleviation

A fuselage cradle support assembly, which can be used as part of a jacking system during aircraft manufacture, is described. The fuselage cradle support assembly can include an array of fuselage cradles. The fuselage cradle support assembly can be configured to limit motion of each fuselage cradle in a cradle array to only vertical and horizontal movements. The vertical movements can be generated using actuators, such as hydraulic actuators, which are communicatively coupled to one another to distribute loads within the cradle array.
