Narrative:
Descending to srq for approach ATC called traffic at 2 O'clock about 7-8 mi. Acquired visually. Maintained visual on VFR target as it passed behind us on the right. Received 'TA' about 6 mi out, -1100 ft as we descended through 6500 ft (- 500 ft) and received RA 'decrease descent' and then as we leveled at 6000 ft received 'climb' RA. We initiated climb to 6500 ft and returned to 6000 ft, deviating from clearance. We informed approach. We felt we were well clear at all times, and followed TCAS procedures.

Title: ALT DEV ALT EXCURSION FROM ASSIGNED. TCASII RA CAUSED PIC RPTR TO PERFORM AN EVASIVE ACTION CLB TO SATISFY RA.
Narrative: DSNDING TO SRQ FOR APCH ATC CALLED TFC AT 2 O'CLOCK ABOUT 7-8 MI. ACQUIRED VISUALLY. MAINTAINED VISUAL ON VFR TARGET AS IT PASSED BEHIND US ON THE R. RECEIVED 'TA' ABOUT 6 MI OUT, -1100 FT AS WE DSNDED THROUGH 6500 FT (- 500 FT) AND RECEIVED RA 'DECREASE DSCNT' AND THEN AS WE LEVELED AT 6000 FT RECEIVED 'CLB' RA. WE INITIATED CLB TO 6500 FT AND RETURNED TO 6000 FT, DEVIATING FROM CLRNC. WE INFORMED APCH. WE FELT WE WERE WELL CLR AT ALL TIMES, AND FOLLOWED TCAS PROCS.
