## Discrepancy

(CAN) EXCESSIVE LOOSENESS BETWEEN THE TWO HALVES OF THE FLAP AT THE CENTER HINGE ARM POSITION. THE RIBS ON EITHER SIDE OF THE HINGE ARM ARE ASSEMBLED TO THE ARM BY THE USE OF MS20470AD5-24 SOLID RIVETS.  IT WOULD APPEAR THAT THERE HAS BEEN SOME WORKING BETWEEN THE RIVET HEADS AND THE RIBS WHICH HAS CAUSED WEARING OF THE RIB AROUND THE RIVET HOLES.
