## Discrepancy

MAD - FLT 730  PHL TO MAD.  DURING APPROACH, THE FLAPS AUTOMATICALLY LOCKED AT 20 DEGREES DUE TO A LEADING EDGE SLAT ASYMMETRY WARNING.  THE CREW DECLARED AN EMERGENCY, ACCOMPLISHED QRH PROCEDURES, AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE PERFORMED A BITE CHECK OF THE FSEU, AND OPERATED THE SLATS/FLAPS OVER A FULL RANGE.  NO DEFECTS WERE NOTED.  ALSO, THE PHYSICAL INSPECTION OF THE SLATS IN THE DEPLOYED POSITION REVEALED NO DEFECTS.  OK FOR SERVICE.
