Narrative:
Departing mci runway 1L. Departing mci for dfw. Upon flap retraction to 0 degrees, leading edge slat #7 failed to retract. Recycled flaps and visual inspection showed #7 remained extended. Returned mci and landed below maximum landing weight. Slat retracted on after landing clean-up. Maintenance lubricated roller on leading edge slat recycled by maintenance on the ground and checked ok. Departed for dfw again and encountered the same problem. We spoke with maintenance and they recommend pitch/speed changes while recycling the flaps. #7 slat then retracted and we continued to dfw with no further problems. Dispatch concurred based on our fuel load and notified ATC of possible minimum fuel arriving dfw. Landed dfw with 9.7 fuel on board.

Title: A B727 RETURNS TO MCI AFTER TKOF WHEN UNABLE TO RETRACT #7 LEADING EDGE SLAT. WORKED OK ON GND. MAINT LUBRICATED IT AND THEY DEPARTED AGAIN. SAME PROB OCCURS. ACFT MANEUVERS PERFORMED AND SLAT RETRACTED. RPTR MENTIONS MINIMUM FUEL POSSIBLE AT DFW.
Narrative: DEPARTING MCI RWY 1L. DEPARTING MCI FOR DFW. UPON FLAP RETRACTION TO 0 DEGS, LEADING EDGE SLAT #7 FAILED TO RETRACT. RECYCLED FLAPS AND VISUAL INSPECTION SHOWED #7 REMAINED EXTENDED. RETURNED MCI AND LANDED BELOW MAX LNDG WT. SLAT RETRACTED ON AFTER LNDG CLEAN-UP. MAINT LUBRICATED ROLLER ON LEADING EDGE SLAT RECYCLED BY MAINT ON THE GND AND CHKED OK. DEPARTED FOR DFW AGAIN AND ENCOUNTERED THE SAME PROB. WE SPOKE WITH MAINT AND THEY RECOMMEND PITCH/SPD CHANGES WHILE RECYCLING THE FLAPS. #7 SLAT THEN RETRACTED AND WE CONTINUED TO DFW WITH NO FURTHER PROBS. DISPATCH CONCURRED BASED ON OUR FUEL LOAD AND NOTIFIED ATC OF POSSIBLE MINIMUM FUEL ARRIVING DFW. LANDED DFW WITH 9.7 FUEL ON BOARD.
