Narrative:
On visual descent into pit approaching 4000 ft, had called pit in sight and cleared for visual approach. I was flying aircraft manually. Near the ags airport we received an RA on TCASII. I immediately transitioned outside and caught visual on the nearing aircraft. I turned slightly left to pass behind and thought I had arrested my rate of descent to stop at 4000 ft MSL. I believe I lost about 200-300 ft below 4000 ft before the altitude alert came on and I recovered to 4000 ft. To me, it was more important to solve the RA on the other aircraft. We came no closer than approximately 2 mi slant range. I had the other aircraft visually at all times immediately following the TA/RA on our TCASII.

Title: A BOEING 737 FLC RECEIVED A TCASII RA ON APCH TO PIT AND DEPARTED FROM THE ASSIGNED ALT DURING A TURN TO AVOID THE TFC.
Narrative: ON VISUAL DSCNT INTO PIT APCHING 4000 FT, HAD CALLED PIT IN SIGHT AND CLRED FOR VISUAL APCH. I WAS FLYING ACFT MANUALLY. NEAR THE AGS ARPT WE RECEIVED AN RA ON TCASII. I IMMEDIATELY TRANSITIONED OUTSIDE AND CAUGHT VISUAL ON THE NEARING ACFT. I TURNED SLIGHTLY L TO PASS BEHIND AND THOUGHT I HAD ARRESTED MY RATE OF DSCNT TO STOP AT 4000 FT MSL. I BELIEVE I LOST ABOUT 200-300 FT BELOW 4000 FT BEFORE THE ALT ALERT CAME ON AND I RECOVERED TO 4000 FT. TO ME, IT WAS MORE IMPORTANT TO SOLVE THE RA ON THE OTHER ACFT. WE CAME NO CLOSER THAN APPROX 2 MI SLANT RANGE. I HAD THE OTHER ACFT VISUALLY AT ALL TIMES IMMEDIATELY FOLLOWING THE TA/RA ON OUR TCASII.
