Narrative:

While on vectors for approach at 7000 ft assigned altitude, spotted conflicting aircraft as it passed off our right side. First officer was flying and pointed it out as it passed. It was in sight for about 2 seconds, and we had no time to react. The other aircraft appeared to be banking away from us. The other aircraft was not idented, except to be a single engine aircraft with a t-tail. TCASII would have helped in this situation. It would also have helped if approach control would have alerted us to the traffic ahead of time.

Original NASA ASRS Text

Title: LGT AT ASSIGNED ALT HAS NMAC WITH SMA.

Narrative: WHILE ON VECTORS FOR APCH AT 7000 FT ASSIGNED ALT, SPOTTED CONFLICTING ACFT AS IT PASSED OFF OUR R SIDE. FO WAS FLYING AND POINTED IT OUT AS IT PASSED. IT WAS IN SIGHT FOR ABOUT 2 SECONDS, AND WE HAD NO TIME TO REACT. THE OTHER ACFT APPEARED TO BE BANKING AWAY FROM US. THE OTHER ACFT WAS NOT IDENTED, EXCEPT TO BE A SINGLE ENG ACFT WITH A T-TAIL. TCASII WOULD HAVE HELPED IN THIS SIT. IT WOULD ALSO HAVE HELPED IF APCH CTL WOULD HAVE ALERTED US TO THE TFC AHEAD OF TIME.
