Looking for someone familiar with McDonnell Douglas MD-90 aircrafts, and mainly the floor structure, outboard. Outboard floor structure of the MD-90 has the shear web (diaphragm as Douglas calls it), floor beam and then a floor panel which is a thin aluminum sheet with hat channel stiffeners. Trying to figure out through research if this top floor panel is truly a shear panel and carrying aircrafts loads or a closeout panel to simply support carpet and closing out the floor panels to the fuselage. This panel does not tie into the skin of the aircraft where as the lower diaphragm panel does tie into cusp.
My gut instinct is this is not a structural member as it does not seem ridged enough and attachment method is the use of clip-nuts to the seat track. I have no reference or data proving this and was hoping someone could help me out.
Anyone with a reference saying/showing that the upper floor panel/web is a non-structural and does not carry significant aircraft loads.
