## Discrepancy

REF CMM 78-31-24, REV 24, 01JUL2012, FIGURE 3, ITEM 675.  THE 315A2502-102 BOND PANEL HAS VISUAL DELAMINATION ALONG THE AFT EDGE 6.00 FROM THE LOWER EDGE TO 23.00 FROM THE LOWER EDGE.  ULTRASONIC INSPECTION PER NDT MANUAL REVEALS SEVERAL AREAS OF DISBOND THROUGHOUT THE ENTIRE NOZZLE END OF THE PANEL.  AREA MEASURES 19.0 X 71.0".  AN APPROX 6 X 6 REPRESENTATIVE SAMPLE HAS BEEN REMOVED FROM THE 315A2502-102 BOND PANEL.  VISUAL INSPECTION REVEALS THAT THE PERFORATED FACE SHEET OML SURFACE APPEARS TO NOT HAVE BEEN PROPERLY PREPARED PRIOR TO ORIGINAL BONDING.
