## Discrepancy

(CAN) DURING NDT INSPECTION THE HUB WAS FOUND TO HAVE A CRACK INDICATION ON ONE OF THE EARS.  THE INDICATION WAS BLENDED, WITH APPROX. .010-.015 INCH OF MATERIAL BEING REMOVED.  THE HUB WAS THEN RE-INSPECTED AND INDICATIONS OF THE DEFECT WERE STILL EVIDENT UNDER BLACK-LIGHT CONDITIONS.
