I was the pilot monitoring as we approached runway 7R. While configuring for landing; we got an amber ICAS message and rolling motion as I selected flaps from 20 to 25. Also annunciated was the Leading edge light advising us we had an asymmetry problem. I felt the flap handle binding as I moved it toward 25 so I placed it back at 20 degrees. We abandoned the approach to run the checklist.After running the checklist and preparing the cabin and passengers for the landing we went back toward the airport and landed on 7L at our present configuration. We taxied back to the gate without incident. After landing we found that the inboard leading edge slats were only in the takeoff position while the outboard leading edge was in the landing position.
A B767-300 developed an asymmetric leading edge slat accompanied by a binding flap handle and roll motion when flaps 25 was selected on short final. The approach was abandoned; the checklist completed and the flight returned for an uneventful landing.
