What was found
FLOOR PANEL BETWEEN FORWARD AND REAR WING SPARS ON WHICH AFT FACING CENTER SEATS ARE MOUNTED IS DELAMINATING. THE FLOOR PANEL CONSISTS OF 2 SHEETS OF ALUMINUM (.040 INCH) WITH A SOUND DEADENING STIFF FOAM BETWEEN THEM. THE SEAT MOUNTING BRACKETS ARE BOLTED THRU BOTH SHEETS, BUT THIS STILL MAY BE A STRUCTURE ISSUE. HAVE CALLED MFG FOR GUIDANCE, BUT HAVE NOT HEARD ANYTHING AS YET.
