The KnuckleSaver Binder Release is a safety tool that releases lever-type chain binders with reduced impact danger to the operator. Essentially a J-hook with handles, the operator engages the hook to the handle of the lever-binder and pulls which releases the tension on the binder without dangerous “hands-on” contact with the binder. 1. The KnuckleSaver Binder Release tool is a metal (plastic , composite , or other materials) J-style hook of appropriate length with handles affixed perpendicular to—and reverse From—the J hook , up the tool from the back of the hook. The handle(s) may be complete with plastic/rubber handgrips. There is a hand shield of wide metal (plastic , composite , or other materials) bar stock or sheet metal (plastic , composite , or other materials) that runs flat up the length of the tool to isolate the users hand from the released binder handle when it springs upward. The operator grips the handle(s) , slides the J-hook under the binder handle and pulls up on the lever (binder handle). Once the lever is forced past the release point , kinetic tension will whip the handle upwards under pressure and it will slide harmlessly past the operator's hands along the shield—and the binder is safely released.2. Device as recited in claim 1 , wherein there is a reverse hook on the obverse side and approximately two inches up the frame of the tool from the primary J-hook.

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. 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.2.
