## Discrepancy

CREW REPORTED THAT UPON APPROACH, THEY RECEIVED A "FLAP FAIL" MESSAGE.  ABORTED LANDING TO RUN QRH.  HAD FLAPS 2 AND SLATS 3. DECLARED AN EMERGENCY.  LANDED AND TAXIED TO THE GATE WITHOUT INCIDENT.  MX FOUND BOTH THE LT FLAP T3 AND T4 SKEW SENSORS HAD FAILED. MX R & R BOTH IAW AMM AND OPS CHECKED GOOD.
