## Discrepancy

POST LANDING INSPECTION REVEALED THAT THE NR 1 ENG HAD A SEPARATION OF PN 114-980077-17 SKIN FROM THE PN 114-980077-5 BOND ASSEMBLY & WAS NO LONGER ATTACHED TO THE ACFT.  MX VERIFIED THAT ALL BOND ASSEMBLY FASTENERS WERE IN PLACE & THAT THE FAILURE WAS THE BOND BETWEEN THE SKIN & THE THICKER SUBSTRUCTURE.  ACFT WAS CONTACTED CONCERNING THE FAILURE OF THE BOND & PROVIDED AN APPROVED FIELD REPAIR FOR CORRECTING FAILED BONDS ON THIS ASSEMBLY.  A VISUAL INSPECTION ON THE FLEET DID NOT DISCLOSE IMMINENT FAILURE OF ADDITIONAL PANELS.  WE ARE ISSUING A FLEET CAMPAIGN TO PERFORM DETAILED INSPECTION & REPAIRS AS REQUIRED ON ALL AFFECTED PANELS IN THE FLEET IAW THE FACTORY PROVIDED SERVICE DOCUMENTATION FR-CO-00037.
