## Discrepancy

WHILE REMOVING FLOORING INSULATION BECAUSE OF AGE AND WEAR, CRACKS WERE FOUND IN THE FLOOR PANEL (P/N 50-440012-655), INVESTIGATION FOUND SEVERAL CRACKS IN THE FLOORS SECOND LAYER AND ELEVATOR PULLEY SUPPORT BRACKET (P/N 50-524432-29) AT FS242, JUST INSIDE THE CABIN ENTRY DOOR.  MY CONCERN IS THAT THESE CRACKS WERE UNDER THE FLOORING INSULATION WHICH IS GLUED  TO THE PANEL AND NOT VISIBLE UNTIL THE INSULATION WAS REMOVED, THESE CRACKS MAY HAVE GONE UNDETECTED FOR WHO KNOWS HOW LONG OR UNTIL THE BRACKET FAILED COMPLETELY. PICTURES ARE AVALABLE.
