Method for installing a collapsible mobile platform interior structure

A method of installing an interior structure of a mobile platform, said method comprising:

• carrying a lightweight collapsible frame through a man-door of a mobile platform while the collapsible frame is in a collapsed state, the lightweight collapsible frame being of dimensions suitable to form at least one of a galley, a lavatory, an overhead mounted compartment, an elevator shaft, or an overhead mounted compartment;
• expanding the collapsible frame into an expanded state to provide at least a portion of a load bearing frame for a mobile platform interior structure, the collapsible frame including:
• a pair of folding end sections that each include a folding top rail and a folding bottom rail fixedly coupled to a pair of end rails;
• and at least a pair of side sections that each include a top rail and a bottom rail fixedly coupled to a pair of end rails, and at least one racking rail diagonally connected between the respective side section top rail and bottom rail, the side section end rails longitudinally hingedly connected to the end rails of the folding end sections;
• attaching a plurality of interchangeable panels to the collapsible frame to form interior surfaces of the mobile platform interior structure;
• providing at least one of the plurality of interchangeable panels with an indexing feature that enables adjustable positioning of the at least one interchangeable panel on the lightweight collapsible frame using a fastener which is operably secured to the at least one interchangeable panel at the indexing feature;
• and
• connecting the collapsible frame while in its said expanded state to the mobile platform to form an integral portion of the mobile platform.
