Narrative:
On arrival to slc, we were cleared, after turning left base from downwind, for visual approach to runway 34L. Simultaneous approachs were being conducted to runways 34L and 34R. We had the prior aircraft, air carrier Y B757 and the airport in sight continuously. On base turn, overhead salt lake city municipal #2 airport, we got a TCASII TA initially, then followed by a TCASII RA to climb. My speed was 210 KTS slowing to 180 KTS and descending from 8000 ft MSL. I started to climb. Then we got an immediate 'descend' TCASII RA. Both of these events, combined, allowed our aircraft to overshoot into runway 34R approach path. Immediate correction to the left was made with tower inquiring to our runway intention. No further deviations happened throughout the rest of the approach. Landing was completed. Prior to this approach, I have witnessed TCASII TA over slc municipal #2 before, but never an RA. That airport traffic pattern should be studied for other TA/RA advisory services.

Title: A B767-200 FLC OVERSHOOTS THEIR ASSIGNED RWY DURING AN EVASIVE ACTION CLB INITIATED BY A TCASII RA NEAR U42 MUNI ARPT 11 MI S OF SLC, UT.
Narrative: ON ARR TO SLC, WE WERE CLRED, AFTER TURNING L BASE FROM DOWNWIND, FOR VISUAL APCH TO RWY 34L. SIMULTANEOUS APCHS WERE BEING CONDUCTED TO RWYS 34L AND 34R. WE HAD THE PRIOR ACFT, ACR Y B757 AND THE ARPT IN SIGHT CONTINUOUSLY. ON BASE TURN, OVERHEAD SALT LAKE CITY MUNICIPAL #2 ARPT, WE GOT A TCASII TA INITIALLY, THEN FOLLOWED BY A TCASII RA TO CLB. MY SPD WAS 210 KTS SLOWING TO 180 KTS AND DSNDING FROM 8000 FT MSL. I STARTED TO CLB. THEN WE GOT AN IMMEDIATE 'DSND' TCASII RA. BOTH OF THESE EVENTS, COMBINED, ALLOWED OUR ACFT TO OVERSHOOT INTO RWY 34R APCH PATH. IMMEDIATE CORRECTION TO THE L WAS MADE WITH TWR INQUIRING TO OUR RWY INTENTION. NO FURTHER DEVS HAPPENED THROUGHOUT THE REST OF THE APCH. LNDG WAS COMPLETED. PRIOR TO THIS APCH, I HAVE WITNESSED TCASII TA OVER SLC MUNI #2 BEFORE, BUT NEVER AN RA. THAT ARPT TFC PATTERN SHOULD BE STUDIED FOR OTHER TA/RA ADVISORY SVCS.
