What was found
THRUST REVERSER C-DUCT HAD A SECTION OF DEBONDED INNER SKIN THAT WAS REMOVED FOR REPAIR EVALUATION. ONCE THE SKIN WAS REMOVED, DISCOVERED THE PROTECTIVE COVERING FOR THE PRE-PREG ADHESIVE FILM WAS NOT REMOVED FROM THE CORE TO INNER SOLID SKIN BOND LINE SIDE. THIS MANUFACTURING QUALITY ESCAPEMENT REDUCES THE BOND LINE STRENGTH AND SERIOUSLY COMPROMISES THE DURABILITY, STRENGTH AND LONGEVITY OF THE BONDED ASSEMBLY.
