Narrative:
During flap retraction on departure from dfw, leading edge flaps and slats jammed in various asymmetrical configns. Trailing edge flaps came up on schedule. All attempts to correct leading edge flaps or raise them failed. Could not continue flight due to speed and altitude restraints in this confign. I returned to dfw and on arrival, had crash fire rescue equipment team meet the aircraft to inspect brakes due to the flaps 15 degrees reference +15 KTS landing speed. The landing runway was runway 17R, and brakes were not over heated during landing. Taxied to gate and the aircraft was taken OTS and the flight canceled. Further inspection revealed that the leading edge devices were stuck in various configns.

Title: RETURN LAND DICTATED TO A PIC OF A B737 WHEN THE LEADING EDGE FLAPS AND SLATS WILL NOT RETRACT AFTER TKOF FROM DFW, TX.
Narrative: DURING FLAP RETRACTION ON DEP FROM DFW, LEADING EDGE FLAPS AND SLATS JAMMED IN VARIOUS ASYMMETRICAL CONFIGNS. TRAILING EDGE FLAPS CAME UP ON SCHEDULE. ALL ATTEMPTS TO CORRECT LEADING EDGE FLAPS OR RAISE THEM FAILED. COULD NOT CONTINUE FLT DUE TO SPD AND ALT RESTRAINTS IN THIS CONFIGN. I RETURNED TO DFW AND ON ARR, HAD CFR TEAM MEET THE ACFT TO INSPECT BRAKES DUE TO THE FLAPS 15 DEGS REF +15 KTS LNDG SPD. THE LNDG RWY WAS RWY 17R, AND BRAKES WERE NOT OVER HEATED DURING LNDG. TAXIED TO GATE AND THE ACFT WAS TAKEN OTS AND THE FLT CANCELED. FURTHER INSPECTION REVEALED THAT THE LEADING EDGE DEVICES WERE STUCK IN VARIOUS CONFIGNS.
