## Discrepancy

DURING REPAIR, AVIALL WHEEL AND BRAKE SERVCIES FOUND THE OUTBOARD WHEEL HALVE CRACKED.  AVIALL HAS SENT THE WHEEL TO BF GOODRICH FOR ANALYSIS.  THE WHEEL ASSEMBLY FAILED DUE TO FATIGUE CRACKS ORIGINATING AT THE CORNER OF THE HOLE ON THE MATING FACE SIDE OF THE WHEEL. THE 3-1446-1 WHEEL HALVES ARE BEING REPLACED ON ATTRITION BY THE 3-1544.
