Narrative:

We were on a phx approach control vector. 1ST call from the controller was 'VFR traffic at 12 O'clock position 2 mi, 4800 ft climbing.' we were on our assigned altitude of 5000 ft. Seconds later, call from controller, 'if you don't see him, turn left to 250 degrees.' at that time, both myself and the copilot saw the C206 dead-on at the same level as our aircraft. I made a hard left descending turn to avoid the C206. I lost almost 500 ft and probably turned past 250 degree heading as the C206 looked very close. The copilot saw the C206 go by the right side of the citation. He estimated the C206 at 1/4 to 1/2 mi from us. Our aircraft does not have TCASII. (I wish it did!) it seems to me that the controller waited too long to call out the traffic or he (C206) just popped up. The total time for us to hear the controller's calls and then see the aircraft was probably around 20 seconds. In the evasive maneuver, I'm sure I was off altitude by more than 300 ft and off heading, but I don't see how else I could have handled the situation. The controller said nothing further about the incident. I called the phx approach control facility later from the ground. The guy on duty said he had no reports of a problem. The C206 acted from his flight path, that he never saw us.

Title: C560 CREW HAVE A SERIOUS CONFLICT WITH A C206 ISSUED AS TFC BY THE P50 AT 2 MI, CLBING.

Narrative: WE WERE ON A PHX APCH CTL VECTOR. 1ST CALL FROM THE CTLR WAS 'VFR TFC AT 12 O'CLOCK POS 2 MI, 4800 FT CLBING.' WE WERE ON OUR ASSIGNED ALT OF 5000 FT. SECONDS LATER, CALL FROM CTLR, 'IF YOU DON'T SEE HIM, TURN L TO 250 DEGS.' AT THAT TIME, BOTH MYSELF AND THE COPLT SAW THE C206 DEAD-ON AT THE SAME LEVEL AS OUR ACFT. I MADE A HARD L DSNDING TURN TO AVOID THE C206. I LOST ALMOST 500 FT AND PROBABLY TURNED PAST 250 DEG HDG AS THE C206 LOOKED VERY CLOSE. THE COPLT SAW THE C206 GO BY THE R SIDE OF THE CITATION. HE ESTIMATED THE C206 AT 1/4 TO 1/2 MI FROM US. OUR ACFT DOES NOT HAVE TCASII. (I WISH IT DID!) IT SEEMS TO ME THAT THE CTLR WAITED TOO LONG TO CALL OUT THE TFC OR HE (C206) JUST POPPED UP. THE TOTAL TIME FOR US TO HEAR THE CTLR'S CALLS AND THEN SEE THE ACFT WAS PROBABLY AROUND 20 SECONDS. IN THE EVASIVE MANEUVER, I'M SURE I WAS OFF ALT BY MORE THAN 300 FT AND OFF HEADING, BUT I DON'T SEE HOW ELSE I COULD HAVE HANDLED THE SIT. THE CTLR SAID NOTHING FURTHER ABOUT THE INCIDENT. I CALLED THE PHX APCH CTL FACILITY LATER FROM THE GND. THE GUY ON DUTY SAID HE HAD NO RPTS OF A PROB. THE C206 ACTED FROM HIS FLT PATH, THAT HE NEVER SAW US.
