## Discrepancy

(CAN) FOR THE SECOND TIME IN 20 MONTHS, A BRAKE UNIT, PN AHA2227-6 HAD TO BE REPLACED DUE TO ROTOR CLIP FAILURE.  THE PROBLEMS WAS OBSERVED DURING BRAKE INSPECTION AFTER MAIN WHEEL CHANGE.  BOTH BRAKE UNITS WERE MODIFIED IAW SB AHA2227-32-1304.  THIS SB IS IMPLEMENTED TO IMPROVE THE ROTOR CLIP DESIGN DUE TO BRAKE ROTOR FAILURE.
