Abstract: A pallet frame assembly is designed to support and retain various loads with the interior of a commercial aircraft. Moreover, the pallet assembly maintains those loads in a manner which facilitates the removable but secure attachment of a load retaining cover or the like structure in overlying relation to the freight mounted on the base of the pallet. More specifically, the pallet frame assembly comprises a base formed preferably, but not necessarily, of a solid sheet of high strength, light weight material, such as, for example, metal. The base is connectable with a track assembly which forms a frame. The track assembly preferably comprises a plurality of track segments, and four segments are used for a pallet having a rectangular or square shape. Each of the track segments might also be formed of a light weight, high strength metal, or other suitable material.
