Narrative:

On final approach, inside OM ILS 12R-hon TCASII shows 'extremely close' target on parallel approach to 12L. Tower advises us and says 'he has you in sight.' favored right side of localizer and stayed slightly high on GS to facilitate visual contact. About that time (according to a tower person in later phone conversation) an small transport was making a visual approach to 22. At some point in his approach he was advised to make a left turn. Instead he made a right turn directly into our path on the ILS. We were trying to make visual contact with the TCASII target on our left and were not aware of any other traffic. TCASII announced 'monitor vertical speed' then 'climb, climb, climb' showing 2000 FPM rate of climb (green band). Although we had been assured our traffic to left 'had us in sight,' I commanded first officer (who was PF) to obey TCASII climb command. Small transport that had allegedly made 'wrong turn' passed 100-200 ft below us left to right 'less than a mi' according to flight engineer. I never saw that aircraft. Evasive climb maneuver accomplished with no 'unusual attitudes.' circled to land uneventfully. Tower apologized, ground control apologized. Tower personnel obviously assumed small transport would make left turn, lost visual contact and never knew we were on 'collision course.' past 'spurious' TCASII warnings almost made us ignore climb command. I'm glad we didn't. Much too close for comfort! Small transport pilot should have turned left or if unable, let tower know his intentions to turn right.

Title: ACR ON APCH. TCASII SHOWS CLOSE PROX TARGET FROM ACFT ON PARALLEL APCH. CTLR SAYS TFC HAS YOU IN SIGHT. HAS TCASII RA TO CLB WHILE LOOKING FOR TFC. RESPONDS. TFC CROSSES 100-200 FT BELOW. NOT PARALLEL TFC.

Narrative: ON FINAL APCH, INSIDE OM ILS 12R-HON TCASII SHOWS 'EXTREMELY CLOSE' TARGET ON PARALLEL APCH TO 12L. TWR ADVISES US AND SAYS 'HE HAS YOU IN SIGHT.' FAVORED R SIDE OF LOC AND STAYED SLIGHTLY HIGH ON GS TO FACILITATE VISUAL CONTACT. ABOUT THAT TIME (ACCORDING TO A TWR PERSON IN LATER PHONE CONVERSATION) AN SMT WAS MAKING A VISUAL APCH TO 22. AT SOME POINT IN HIS APCH HE WAS ADVISED TO MAKE A L TURN. INSTEAD HE MADE A R TURN DIRECTLY INTO OUR PATH ON THE ILS. WE WERE TRYING TO MAKE VISUAL CONTACT WITH THE TCASII TARGET ON OUR L AND WERE NOT AWARE OF ANY OTHER TFC. TCASII ANNOUNCED 'MONITOR VERT SPD' THEN 'CLB, CLB, CLB' SHOWING 2000 FPM RATE OF CLB (GREEN BAND). ALTHOUGH WE HAD BEEN ASSURED OUR TFC TO L 'HAD US IN SIGHT,' I COMMANDED FO (WHO WAS PF) TO OBEY TCASII CLB COMMAND. SMT THAT HAD ALLEGEDLY MADE 'WRONG TURN' PASSED 100-200 FT BELOW US L TO R 'LESS THAN A MI' ACCORDING TO FE. I NEVER SAW THAT ACFT. EVASIVE CLB MANEUVER ACCOMPLISHED WITH NO 'UNUSUAL ATTITUDES.' CIRCLED TO LAND UNEVENTFULLY. TWR APOLOGIZED, GND CTL APOLOGIZED. TWR PERSONNEL OBVIOUSLY ASSUMED SMT WOULD MAKE L TURN, LOST VISUAL CONTACT AND NEVER KNEW WE WERE ON 'COLLISION COURSE.' PAST 'SPURIOUS' TCASII WARNINGS ALMOST MADE US IGNORE CLB COMMAND. I'M GLAD WE DIDN'T. MUCH TOO CLOSE FOR COMFORT! SMT PLT SHOULD HAVE TURNED L OR IF UNABLE, LET TWR KNOW HIS INTENTIONS TO TURN R.
