## Discrepancy

(CAN)  FLOAT INSTALLATION THE REAR SPREADER BAR EXHIBITED SIGNS OF CORROSION PRODUCT EXITING THE HOLLOW TUBE ASSY.  FURTHER INTERNAL INVESTIGATION REVEALED SEVERE CORROSION INTERNALLY IN THE TUBE ASSY, D30511-1.  SPREADER BAR REPLACED, FWD SPREADER BAR WAS REPLACED EARLIER FOR AN UNRELATED ISSUE, REINVESTIGATION OF THIS SPREADER BAR INDICATED IDENTICAL INTERNAL CORROSION.  ON EXTERNAL INSPECTION NO SIGN OF CORROSION IS EVIDENT, A BOROSCOPE IS REQUIRED TO INTERNALLY INSPECT THE SPREADER BAR.  THE MFG HAS POSSESSION OF THE DEFECTIVE SPREADER BAR ASSY.
