Apparatus for adapting aircraft floors and related methods are disclosed. An example floor of an aircraft includes a floor beam, a seat track, and a cap coupled to the seat track. The cap is disposed over the seat track and the floor beam. The example floor includes a floor panel aligned with the cap.

Apparatus for adapting aircraft floors and related methods

An attachment system and method that includes first and second fittings, a first eccentric bushing positioned within the first fitting, and a second eccentric bushing positioned within the second fitting. The system may include a first friction washer positioned between the first bushing and first fitting and a second friction washer positioned between the second bushing and the second fitting. A coating on the exterior of the friction washers prohibits rotation of the bushings with respect to the fittings. The coating may be a nickel-diamond coating that prohibits rotation even in the presence of a lubricant. The first fitting may be a frame fitting connected to a fuselage of an aircraft and the second fitting may be a beam fitting connected to the floor of the aircraft. The system may include lock plates that engage lock stops to prohibit rotation of the bushings in combination with the coated friction washers.

Anti-rotation for eccentric bushings

A laminated reinforced member that provides bending and stiffening support and that includes metal reinforcing sheets, and a method of making the member. Metal reinforcing sheets at connection locations eliminate the need for additional external connection reinforcements for engaging connectors.
