## Discrepancy

DURING PRELIMINARY INCOMING INSPECTION ON 7/11/05 IT WAS NOTED THAT NR3 MAIN WHEEL TIRE HAD CRACKS OR SPLITS RADIALLY IN BETWEEN TREAD.  IT WAS DETERMINED THAT THIS TIRE WAS INSTALLED ON THE NR 3 WHEEL (PN AH52788, SN 675/8129 ON 6/8/05 ACTT 11,926.5, ACTL 12,443)  AC TIMES ON 7/11/05 (WHEN DEFECT WAS NOTED) WERE ACTT 11996.2, ACTL 12,552.  THE TIRE HAS AC MFG TRACKING NR 983290, WO/CONTRACT/INVOICE NR 506021.  IT IS SUSPECTED THAT THE CRACKS/SPLITS IN THE TREAD ARE DUE TO POSSIBLE MFG FLAW.  IF UNDETECTED THIS COULD HAVE BEEN POTENTIALLY VERY DANGEROUS SITUATION UNDER LANDING LOADS.  THE CRACKED/SPLIT TIRE WAS REMOVED AND REPLACED WITH A NEW TIRE AND THE WHEEL/BOLTS WERE NDT INSPECTED.
