Narrative:
While on radar vectors to ILS runway 19R at john wayne airport, we had to take evasive action to avoid traffic at our altitude of 3000 ft AGL. We were heading 240 degrees when we got a TCASII TA. We saw the aircraft and it appeared to be on final ILS runway 19R to john wayne. TCASII TA turned into RA to 'descend.' first officer, PF, did not comply with TCASII RA. We both still thought traffic was on final to john wayne. I took evasive action, right turn, as approach control gave us 270 degree heading to avoid traffic. I should have ordered first officer to comply with TCASII RA or taken control of aircraft. I relied on my visual perception instead of TCASII. First officer was new to company on high minimums. Next time I will believe TCASII.

Title: FO OF A B737-300 FAILED TO RESPOND TO A TCASII RA RESULTING IN APCH CTLR ISSUING A HEADING CHANGE TO PROVIDE SEPARATION.
Narrative: WHILE ON RADAR VECTORS TO ILS RWY 19R AT JOHN WAYNE ARPT, WE HAD TO TAKE EVASIVE ACTION TO AVOID TFC AT OUR ALT OF 3000 FT AGL. WE WERE HEADING 240 DEGS WHEN WE GOT A TCASII TA. WE SAW THE ACFT AND IT APPEARED TO BE ON FINAL ILS RWY 19R TO JOHN WAYNE. TCASII TA TURNED INTO RA TO 'DSND.' FO, PF, DID NOT COMPLY WITH TCASII RA. WE BOTH STILL THOUGHT TFC WAS ON FINAL TO JOHN WAYNE. I TOOK EVASIVE ACTION, R TURN, AS APCH CTL GAVE US 270 DEG HDG TO AVOID TFC. I SHOULD HAVE ORDERED FO TO COMPLY WITH TCASII RA OR TAKEN CTL OF ACFT. I RELIED ON MY VISUAL PERCEPTION INSTEAD OF TCASII. FO WAS NEW TO COMPANY ON HIGH MINIMUMS. NEXT TIME I WILL BELIEVE TCASII.
