## Discrepancy

THE CREW REPORTED AFTER TAKEOFF FROM KLAX, A FLAP DISAGREEMENT WARNING OCCURRED. THEY PERFORMED A SYSTEM CHECK IN ACCORDANCE WITH QRH AND RECYCLED THE FLAPS, BUT THE FLAP DISAGREEMENT WARNING RETURNED. THE CREW DECLARED AN EMERGENCY, AND LANDED AT KONT WITHOUT INCIDENT. MAINTENANCE PERFORMED A VISUAL INSPECTION OF THE FLAPS AND FOUND NO DEFECTS. THEY ALSO PERFORMED AN OPERATIONAL AND SYSTEM BUILT-IN TEST AND FOUND NO ANOMALIES OR DUPLICATION OF FLAP DISAGREEMENT. THE AIRCRAFT WAS RELEASED AND RETURNED TO SERVICE.
