## Discrepancy

CREW RECEIVED A SLAT FAIL MESSAGE DURING APPROACH, DECLARED EMERGENCY AND LANDED WITHOUT INCIDENT IN CLT.  MAINTENANCE WAS DISPATCHED TO THE A/C TO TROUBLESHOOT, AND FOUND LT O/B SKEW SENSORS TO BE AT FAULT.  MAINTENANCE REMOVED AND REPLACED BOTH LT O/B SKEW SENSORS AND PERFORMED OPS CHECKS PER EMB AMM.  A/C WAS THEN RELEASED BACK INTO SERVICE.
