## Discrepancy

LT WING AFT FLAP TRAILING EDGE HAS 6 INCH SPANWISE BY 4 INCH CHORDWISE DELAMINATION 4 FT INBD FROM OTBD EDGE OF FLAP.   THE ABOVE NOTED DELAM CONDITION WAS DISCOVERED WITH RELATIVELY LOW FLIGHT-HOURS AND FLIGHT-CYCLES.  THE DELAM WAS DUE TO AERODYNAMIC LOADING DURING FLIGHT, ESPECIALLY DURING LANDING WHEN THE FLAP IS POSITIONED MORE DIRECTLY INTO THE AIRSTREAM, AND THUS IS SUBJECT TO MORE AIRLOADS.  THE DELAMINATION WAS REPAIRED.
