Narrative:

We were a VFR aircraft on descent to sna when approach gave us an urgent 30 degree vector for traffic. The other aircraft (a commuter) was on an IFR flight plan and was never given a turn. It seems to me that ATC is reluctant to give IFR aircraft turns for VFR traffic. If that would have happened we would not have come so close.

Original NASA ASRS Text

Title: NMAC BTWN A CPR JET AND A COMMUTER ACFT.

Narrative: WE WERE A VFR ACFT ON DSCNT TO SNA WHEN APCH GAVE US AN URGENT 30 DEG VECTOR FOR TFC. THE OTHER ACFT (A COMMUTER) WAS ON AN IFR FLT PLAN AND WAS NEVER GIVEN A TURN. IT SEEMS TO ME THAT ATC IS RELUCTANT TO GIVE IFR ACFT TURNS FOR VFR TFC. IF THAT WOULD HAVE HAPPENED WE WOULD NOT HAVE COME SO CLOSE.
