## Discrepancy

NR 5 LEADING EDGE SLAT WEDGE, 49 INCH SECTION DEPARTED AIRCRAFT. SUPPLEMENTAL DATA UPDATE REPLACED THE NR 5 LEADING EDGE SLAT.  THE LOSS OF THE 49 INCH SECTION OF THE TRAILING EDGE WEDGE WAS DUE TO DELAMINATION BETWEEN THE SKIN-TO-CORE BOND LINE.  DELAMINATION IS BELIEVED TO BE CAUSED BY WATER INGRESSION.
