## Discrepancy

AIRCRAFT WAS GROUNDED: DESCENDING THROUGH APPROXIMATELY FL200 WE NOTICED A TE EDGE FLAP ASSYMETRY WHERE THE LEFT NEEDLE WAS SHOWING UP AND THE RIGHT NEEDLE WAS SHOWING BETWEEN UP AND 1. AT 8,000 FT WE SELECTED FLAPS1 AT 220 KNOTS AND THERE WAS NO MOVEMENT OF TRAILING EDGE NOR LEADING EDGE DEVICES. CYCLED THE HANDLE ONE MORE TIME BACK TO 0 AND 1 AND FLAPS STILL DID NOT MOVE. HYDRAULICS ALL REMAINED NORMAL. SPLIT INDICATION REMAINED UNTIL AFTER LANDING WHEN BOTH FLAPSTHEN EXTENDED TO 1. AN EMERGENCY WAS DECLARED AND ARFF ROLLED AS A PRECAUTION. AIRCRAFT LANDED WITHOUT INCIDENT. MAINTENANCE REPLACED IAW AMM 27-51-01 PER FIM 27-51-00-810-840.
