Narrative:

Upon visual descent into psp, the approach controller cleared air carrier X for a visual approach to psp. I asked if there was any inbound traffic to psp, he responded with, 'I have a malibu inbound from the west I've turned to the north to avoid you.' the captain began our visual approach. Soon we received a TCASII 'traffic,' then a 'climb, climb.' my view of the TCASII display was 1 mi, dead ahead 400 ft below, at which time I saw the malibu pass under us left to right. During this short period the malibu pilot said, 'hey, what's that jet going to do anyway?' this was the first time the approach controller realized there was a conflict and mentioned the traffic to us. Supplemental information from acn 273066: X did not visually acquire the traffic, although he was shown as traffic on our TCASII. We initiated a descending right turn to base from our downwind altitude of 6000 ft or 7000 ft. Traffic was instructed to turn wbound and had visually acquired us. As we continued our right turn, the traffic trajectory on TCASII was going to pass across our nose. As we passed through 5000 ft we initiated a leveloff with the TCASII displaying only a 200 ft differential in our respective altitudes. We continued to transition into a climb simultaneously with the TCASII transitioning from a TA to an RA. At that point, as we were already in a climb, we complied with the RA.

Narrative: UPON VISUAL DSCNT INTO PSP, THE APCH CTLR CLRED ACR X FOR A VISUAL APCH TO PSP. I ASKED IF THERE WAS ANY INBOUND TFC TO PSP, HE RESPONDED WITH, 'I HAVE A MALIBU INBOUND FROM THE W I'VE TURNED TO THE N TO AVOID YOU.' THE CAPT BEGAN OUR VISUAL APCH. SOON WE RECEIVED A TCASII 'TFC,' THEN A 'CLB, CLB.' MY VIEW OF THE TCASII DISPLAY WAS 1 MI, DEAD AHEAD 400 FT BELOW, AT WHICH TIME I SAW THE MALIBU PASS UNDER US L TO R. DURING THIS SHORT PERIOD THE MALIBU PLT SAID, 'HEY, WHAT'S THAT JET GOING TO DO ANYWAY?' THIS WAS THE FIRST TIME THE APCH CTLR REALIZED THERE WAS A CONFLICT AND MENTIONED THE TFC TO US. SUPPLEMENTAL INFO FROM ACN 273066: X DID NOT VISUALLY ACQUIRE THE TFC, ALTHOUGH HE WAS SHOWN AS TFC ON OUR TCASII. WE INITIATED A DSNDING R TURN TO BASE FROM OUR DOWNWIND ALT OF 6000 FT OR 7000 FT. TFC WAS INSTRUCTED TO TURN WBOUND AND HAD VISUALLY ACQUIRED US. AS WE CONTINUED OUR R TURN, THE TFC TRAJECTORY ON TCASII WAS GOING TO PASS ACROSS OUR NOSE. AS WE PASSED THROUGH 5000 FT WE INITIATED A LEVELOFF WITH THE TCASII DISPLAYING ONLY A 200 FT DIFFERENTIAL IN OUR RESPECTIVE ALTS. WE CONTINUED TO TRANSITION INTO A CLB SIMULTANEOUSLY WITH THE TCASII TRANSITIONING FROM A TA TO AN RA. AT THAT POINT, AS WE WERE ALREADY IN A CLB, WE COMPLIED WITH THE RA.
