Narrative:

Into approach at st louis, we lowered the flaps to flaps 2 degrees. We got the amber light on the front panel for flaps, and check on flight engineer panel. #2 slat indicated it did not come down. We got the checklist out. We were handed over to tower. Told tower of our problem, and that we needed delay vectors to do the checklist. We got out the emergency checklist -- one leading edge device inoperative checklist. We did it, told approach we were ready to come back, and that we had to declare an emergency as per company procedures, and had equipment standing by. Gave them souls on board, fuel, hazmat information. Landing went fine. After taxi in, we left flaps at 15 degrees, so we could see visually, after we parked, what true position slat #2 was in. Well, slat #2 was in the proper position after all. We cycled the flaps there on ground 3 times. Slat #2 worked great each time, but with amber light, and flight engineer showed slat #2 was not down in proper position. Mechanic worked on it and got it fixed. After all paperwork done, we went on and to toledo, oh. All I can say, my crew did a great job working together to resolve the problem, do the checklist, get the plane on the ground.

Narrative: INTO APCH AT ST LOUIS, WE LOWERED THE FLAPS TO FLAPS 2 DEGS. WE GOT THE AMBER LIGHT ON THE FRONT PANEL FOR FLAPS, AND CHK ON FE PANEL. #2 SLAT INDICATED IT DID NOT COME DOWN. WE GOT THE CHKLIST OUT. WE WERE HANDED OVER TO TWR. TOLD TWR OF OUR PROB, AND THAT WE NEEDED DELAY VECTORS TO DO THE CHKLIST. WE GOT OUT THE EMER CHKLIST -- ONE LEADING EDGE DEVICE INOP CHKLIST. WE DID IT, TOLD APCH WE WERE READY TO COME BACK, AND THAT WE HAD TO DECLARE AN EMER AS PER COMPANY PROCS, AND HAD EQUIP STANDING BY. GAVE THEM SOULS ON BOARD, FUEL, HAZMAT INFO. LNDG WENT FINE. AFTER TAXI IN, WE LEFT FLAPS AT 15 DEGS, SO WE COULD SEE VISUALLY, AFTER WE PARKED, WHAT TRUE POS SLAT #2 WAS IN. WELL, SLAT #2 WAS IN THE PROPER POS AFTER ALL. WE CYCLED THE FLAPS THERE ON GND 3 TIMES. SLAT #2 WORKED GREAT EACH TIME, BUT WITH AMBER LIGHT, AND FE SHOWED SLAT #2 WAS NOT DOWN IN PROPER POS. MECH WORKED ON IT AND GOT IT FIXED. AFTER ALL PAPERWORK DONE, WE WENT ON AND TO TOLEDO, OH. ALL I CAN SAY, MY CREW DID A GREAT JOB WORKING TOGETHER TO RESOLVE THE PROB, DO THE CHKLIST, GET THE PLANE ON THE GND.
