Actually the incident you're talking about came from a non authorized procedure of pulling the CB's on the LE slats, and selecting the first flap. it allowed a higher cruise altitude. The problem was the FE came back from the lav and saw some cb's out, and reset them. the attendant yaw/roll was sufficient that he couldn't reach the other side cb's. needless to say this came out in the inquiry. Kind of like the go fast switch in the learjet.
