Narrative:

After takeoff from mia, when raising the flaps the leading edge flaps transit amber light remained illuminated. We leveled off at 8000 ft, 220 KIAS and performed the leading edge flaps transit checklist. The leading edge flaps and slats would not retract and the leading edge flaps transit light remained illuminated with all the leading edge device amber transit lights illuminated. We could also visually verify that the leading edge slats were asymmetrical. Slats 1 and 8 appeared fully extended and 2,3,6 and 7 appeared partially extended. We declared an emergency with mia approach control, performed the asymmetrical or no leading edge device procedure for landing checklist and landed at mia at a gross weight of approximately 130000 pounds. The approach and landing were uneventful.

Title: B737-700 CREW HAD LEADING EDGE SLATS THAT WOULD NOT RETRACT AFTER DEPARTING MIA.

Narrative: AFTER TKOF FROM MIA, WHEN RAISING THE FLAPS THE LEADING EDGE FLAPS TRANSIT AMBER LIGHT REMAINED ILLUMINATED. WE LEVELED OFF AT 8000 FT, 220 KIAS AND PERFORMED THE LEADING EDGE FLAPS TRANSIT CHKLIST. THE LEADING EDGE FLAPS AND SLATS WOULD NOT RETRACT AND THE LEADING EDGE FLAPS TRANSIT LIGHT REMAINED ILLUMINATED WITH ALL THE LEADING EDGE DEVICE AMBER TRANSIT LIGHTS ILLUMINATED. WE COULD ALSO VISUALLY VERIFY THAT THE LEADING EDGE SLATS WERE ASYMMETRICAL. SLATS 1 AND 8 APPEARED FULLY EXTENDED AND 2,3,6 AND 7 APPEARED PARTIALLY EXTENDED. WE DECLARED AN EMER WITH MIA APCH CTL, PERFORMED THE ASYMMETRICAL OR NO LEADING EDGE DEVICE PROC FOR LNDG CHKLIST AND LANDED AT MIA AT A GROSS WT OF APPROX 130000 LBS. THE APCH AND LNDG WERE UNEVENTFUL.
