AC HAD BEEN OUT FOR ENGINE RUNS AFTER AN ENGINE CHANGE AND WAS IN THE HANGAR, IT WAS CHECKED AND FOUND TO HAVE A SECTION OF THE NR 2 MAIN WHEEL P/N AHA1489 OB FLANGE MISSING. THE OUTER WHEEL HALF P/N AHA1483 IS FOUND IN THE MFG CMM IPL 32-42-59 FIG NR 1 ITEM NR 160.  THIS WHEEL WAS ON BUILD 17 AND HAD BEEN NDT AT THAT TIME WITH NO DEFECTS NOTED AT THE TIME. THE WHEEL WAS REPLACED AND THE WHEEL HALF HAS BEEN SENT TO MFG FOR ANAYLSIS.  WE WILL FOLLOW-UP ON THE INCIDENT ONCE WE HEAR BACK FROM THE MANUFACTURER WITH THEIR FINDINGS.
