Narrative:

Approach control gave us a runway change inbound from runway 8L to runway 9R and issued the ILS frequency. At that time the first officer briefed the approach for the changed runway and dialed in the wrong frequency as issued by ATC. The frequency as issued by ATC was for the wrong runway. It seemed to be taking too long to intercept the final approach localizer and I rechked the approach plate and attempted to retune the two receivers to the correct frequency. Immediately after this attempt the tower called the flight, and notified us that we had gone through the proper final approach path and were about to encroach the other runways final approach path. We were turned right, outbnd perpendicular to final and repositioned for another final approach. At no time were we notified of a 'near miss' or possible violation action as a result of this near encroachment. I feel that the problem was a direct result of a runway change during IFR conditions and a critical phase of flight. In addition to the issuance of what the entire crew feels was an incorrect frequency.

Title: ACR LGT OVERSHOT LOC INTERCEPT FOR IAP ILS APCH TO ATL.

Narrative: APCH CTL GAVE US A RWY CHANGE INBND FROM RWY 8L TO RWY 9R AND ISSUED THE ILS FREQ. AT THAT TIME THE F/O BRIEFED THE APCH FOR THE CHANGED RWY AND DIALED IN THE WRONG FREQ AS ISSUED BY ATC. THE FREQ AS ISSUED BY ATC WAS FOR THE WRONG RWY. IT SEEMED TO BE TAKING TOO LONG TO INTERCEPT THE FINAL APCH LOC AND I RECHKED THE APCH PLATE AND ATTEMPTED TO RETUNE THE TWO RECEIVERS TO THE CORRECT FREQ. IMMEDIATELY AFTER THIS ATTEMPT THE TWR CALLED THE FLT, AND NOTIFIED US THAT WE HAD GONE THROUGH THE PROPER FINAL APCH PATH AND WERE ABOUT TO ENCROACH THE OTHER RWYS FINAL APCH PATH. WE WERE TURNED R, OUTBND PERPENDICULAR TO FINAL AND REPOSITIONED FOR ANOTHER FINAL APCH. AT NO TIME WERE WE NOTIFIED OF A 'NEAR MISS' OR POSSIBLE VIOLATION ACTION AS A RESULT OF THIS NEAR ENCROACHMENT. I FEEL THAT THE PROB WAS A DIRECT RESULT OF A RWY CHANGE DURING IFR CONDITIONS AND A CRITICAL PHASE OF FLT. IN ADDITION TO THE ISSUANCE OF WHAT THE ENTIRE CREW FEELS WAS AN INCORRECT FREQ.
