## Discrepancy

DURING A POST FLIGHT CHECK, A MECHANIC NOTICED A BULGE ON THE UNDERSIDE OF THE IB LEADING EDGE OF THE LT WING.  UPON FURTHER INVESTIGATION, A DELAMINATION AREA OF APPROXIMATELY 22 INCHES X 10 INCHES WAS FOUND.  AFTER REMOVAL OF THE LEADING EDGE AND CLOSER  EXAMINATION THE DELAMINATION WAS CONTAINED WITHIN THE EXHAUST GAS FLOW PATH FROM THE LT ENGINE IB EXHAUST STACK.  AFTER CONTACTING MFG, IT WAS DETERMINED THAT THE PART WAS NOT REPAIRABLE AND THE PART MUST BE REPLACED.  (GL19200504135)
