## Discrepancy

AIRCRAFT EXPERIENCED LEADING EDGE SLAT PROBLEM. THE NR 6 SLAT TRAILING EDGE WEDGE BROKE APART.  A SECTION OF THE TRAILING EDGE WEDGE SEPARATED FROM THE SLAT.  THE SUSPECT CAUSE OF DAMAGE WAS CORROSION OF THE ALUMINUM HONEYCOMB IN THE TRAILING EDGE WEDGE DUE TO MOISTURE INGRESSION.  INTENSIFIED INSPECTIONS WILL DETECT DELAMINATIONS PRIOR TO SEPARATON FAILURES.
