## Discrepancy

HAD THE #3 BRAKE ASSY FAIL DURING TOWING OPERATIONS CAUSING THE BRAKE TO LOCK UP AND SHED PARTS. UPON INSPECTION AFTER REMOVAL AND A SECOND FAILURE IN THE FLEET WE NOTED THAT IT APPEARS THAT THE RIVETS THAT HOLD THE BRAKE FRICTION MATERIAL WERE INSTALLED INCORRECTLY DURING OVERHAUL. BOTH BRAKE ASSYS WERE OVERHAULED BY SOUTHWIND AVIATION AND SOUTHWIND HAS BEEN NOTIFIED BY SC AVIATION OF THE POSSIBLE ISSUES.
