## Discrepancy

(CAN) UPON LANDING IT WAS NOTED THAT SMOKE AND SPARKS WERE ORIGINATING FROM RT  INBD WHEEL AREA.  MAINTENANCE REMOVED WHEEL AND DISCOVERED BOTH BEARINGS HAD FAILED. IT WAS EVIDENT THAT THE BEARINGS HAD SEVERLY BROKEN DOWN.  THE INNER BEARING APPEARED TO BE THE WORST.  ALSO, THE INNER BEARING ID HAD WELDED ITSELF TO THE AXLE.  ASSOCIATED WHEELS, BRAKE UNITS AND AXLE WERE ALL DAMAGED AND HAD TO BE REPLACED.
