Method and apparatus for supporting an aircraft structure during repair

摘要

Systems and methods for jacking an aircraft structure using beams coupled to seat tracks attached to a floor beam grid structure. Mechanical load distribution plates can have offset lift pin location to allow a certain percentage of the load to be applied to specific seat tracks. Different quantities of seat tracks can be utilized per requirements. Attachment rails that interface with the seat tracks use the same hardware that is used to fasten aircraft seats to the seat tracks. This helps handle the load and prevent damage to the seat tracks. The jacking apparatus also includes load swivels and a hanger link to prevent any side or twisting loads from being applied.

主权项

1. A method for supporting an aircraft structure comprising: (a) placing a beam so that one end protrudes out a first window opening on one side of a fuselage, another end protrudes out a second window opening on another side of the fuselage, and a portion of the beam inside the fuselage overlies a floor that is attached to the fuselage; (b) mechanically coupling the beam to seat tracks on the floor; and (c) raising the beam until at least a portion of the weight of the aircraft structure is supported by the beam via the mechanical coupling of the beam to the seat tracks.
