Narrative:

Approaching dfw at 11000 ft we were given a descent to 5000 ft and told to intercept the runway 31R localizer. Shortly after beginning the descent, we were given a frequency change to 135.5. On initial contact the controller immediately told us to revise our descent and level at 7000 ft (we were passing through approximately 7700 ft at the time). Upon leveling at 7000 ft the controller told us to turn back to a heading of 250 degrees from our current heading of 290 degrees to reintercept the runway 31R localizer. We had overshot the localizer during the rapid transition to the revised leveloff at 7000 ft. Then intercepted the runway 31R localizer and the flight continued normally. No mention of any conflict was made by the controller.

Title: AN ACR MD80 FLC OVERSHOT THE LOC WHILE CONCENTRATING ON LEVELING OFF AT A REVISED ASSIGNED ALT.

Narrative: APCHING DFW AT 11000 FT WE WERE GIVEN A DSCNT TO 5000 FT AND TOLD TO INTERCEPT THE RWY 31R LOC. SHORTLY AFTER BEGINNING THE DSCNT, WE WERE GIVEN A FREQ CHANGE TO 135.5. ON INITIAL CONTACT THE CTLR IMMEDIATELY TOLD US TO REVISE OUR DSCNT AND LEVEL AT 7000 FT (WE WERE PASSING THROUGH APPROX 7700 FT AT THE TIME). UPON LEVELING AT 7000 FT THE CTLR TOLD US TO TURN BACK TO A HDG OF 250 DEGS FROM OUR CURRENT HDG OF 290 DEGS TO REINTERCEPT THE RWY 31R LOC. WE HAD OVERSHOT THE LOC DURING THE RAPID TRANSITION TO THE REVISED LEVELOFF AT 7000 FT. THEN INTERCEPTED THE RWY 31R LOC AND THE FLT CONTINUED NORMALLY. NO MENTION OF ANY CONFLICT WAS MADE BY THE CTLR.
