## Discrepancy

TAIL ROTOR BLADE PN 355A12005014, SN 24326 WAS RECEIVED NEW AND INSTALLED ON AC.  THE BLADE FAILED TO TRACK & BALANCE AND WAS DETERMINED TO BE THE CAUSE AND WAS REMOVED AND SENT IN FOR REPAIR AFTER ACCUMULATING .2HRS TIS DURING TRACK & BALANCE OPERATION.  THE BLADE WAS RECEIVED BACK FROM REPAIR AND INSTALLED WHERE IT AGAIN FAILED TO TRACK & BALANCE.  THE REPAIR SHOWS THAT THE TRACKING FINGERS WERE REPLACED.
