Narrative:
While on final approach to dfw airport for runway 17C, I noticed a target on the TCASII getting close. I was flying, asked the captain if he could see an aircraft about 7-8 O'clock position. As we were talking, the target went from TA to RA within a few seconds. I followed TCASII action necessary and the captain and I got a brief look at 2 huge landing lights. We both agreed that TCASII had saved us from a midair. There was no advisory from ATC and when we brought it up ATC said they would 'check it out.' apparently the aircraft in question was supposed to be on approach for runway 17L. Our aircraft was on course with the autoplt flying until we took evasive action. Our concern was that neither ATC that controls the runway 17L or runway 17C runways pointed us out. This happened at a very busy time but the results could have been serious. The crew was well rested as it was our first leg and alert to the impeding problem.

Title: AN ATR72 FO'S RPT ON A POSSIBLE NMAC WHILE FLYING A NIGHT OP APCH TO RWY 17C, 10 NM N OF DFW, TX.
Narrative: WHILE ON FINAL APCH TO DFW ARPT FOR RWY 17C, I NOTICED A TARGET ON THE TCASII GETTING CLOSE. I WAS FLYING, ASKED THE CAPT IF HE COULD SEE AN ACFT ABOUT 7-8 O'CLOCK POS. AS WE WERE TALKING, THE TARGET WENT FROM TA TO RA WITHIN A FEW SECONDS. I FOLLOWED TCASII ACTION NECESSARY AND THE CAPT AND I GOT A BRIEF LOOK AT 2 HUGE LNDG LIGHTS. WE BOTH AGREED THAT TCASII HAD SAVED US FROM A MIDAIR. THERE WAS NO ADVISORY FROM ATC AND WHEN WE BROUGHT IT UP ATC SAID THEY WOULD 'CHK IT OUT.' APPARENTLY THE ACFT IN QUESTION WAS SUPPOSED TO BE ON APCH FOR RWY 17L. OUR ACFT WAS ON COURSE WITH THE AUTOPLT FLYING UNTIL WE TOOK EVASIVE ACTION. OUR CONCERN WAS THAT NEITHER ATC THAT CTLS THE RWY 17L OR RWY 17C RWYS POINTED US OUT. THIS HAPPENED AT A VERY BUSY TIME BUT THE RESULTS COULD HAVE BEEN SERIOUS. THE CREW WAS WELL RESTED AS IT WAS OUR FIRST LEG AND ALERT TO THE IMPEDING PROB.
