Narrative:

While traveling ssebound on V363 we were vectored to a heading of 120 degrees at 4000' MSL. With our high wing aircraft our view during the turn was blocked, although we did clear the turn prior to initiating. When we rolled wings level an small transport came into view, gear down, flaps at 10 degrees and descending on a collision course. Immediately I pulled up and over the small transport resulting in the near miss. The small transport made no movement to avoid us. I also immediately advised coast approach of our situation at which time the 'traffic alert' less than 1 mi was given to us by coast. The problem arose because coast for one reason or another (probably because of an incredible amount of traffic with an antiquated ATC system) didn't call traffic to our attention and secondly because the small transport probably never even saw the traffic outside of their wind screen (us). I believe that the problem could have been solved first with the old see and avoid method on the part of the small transport pilot (and all aircraft, for that matter), because I believe all of us on an IFR flight plan are lulled into a small sense of security (which incidentally is a false security). Secondly, I believe the ATC system should be improved, now! The public should be made aware of the situation in order that public funding for the ATC improvements might be initiated (certainly we were never get the trust fund monies released in time to make a difference. Fortunately, nothing resulted from this incident and we are all alive to warn others from our experience.

Title: ACFT ON VECTOR CAME IN CLOSE PROX TO ANOTHER ACFT.

Narrative: WHILE TRAVELING SSEBOUND ON V363 WE WERE VECTORED TO A HDG OF 120 DEGS AT 4000' MSL. WITH OUR HIGH WING ACFT OUR VIEW DURING THE TURN WAS BLOCKED, ALTHOUGH WE DID CLR THE TURN PRIOR TO INITIATING. WHEN WE ROLLED WINGS LEVEL AN SMT CAME INTO VIEW, GEAR DOWN, FLAPS AT 10 DEGS AND DSNDING ON A COLLISION COURSE. IMMEDIATELY I PULLED UP AND OVER THE SMT RESULTING IN THE NEAR MISS. THE SMT MADE NO MOVEMENT TO AVOID US. I ALSO IMMEDIATELY ADVISED COAST APCH OF OUR SITUATION AT WHICH TIME THE 'TFC ALERT' LESS THAN 1 MI WAS GIVEN TO US BY COAST. THE PROB AROSE BECAUSE COAST FOR ONE REASON OR ANOTHER (PROBABLY BECAUSE OF AN INCREDIBLE AMOUNT OF TFC WITH AN ANTIQUATED ATC SYS) DIDN'T CALL TFC TO OUR ATTN AND SECONDLY BECAUSE THE SMT PROBABLY NEVER EVEN SAW THE TFC OUTSIDE OF THEIR WIND SCREEN (US). I BELIEVE THAT THE PROB COULD HAVE BEEN SOLVED FIRST WITH THE OLD SEE AND AVOID METHOD ON THE PART OF THE SMT PLT (AND ALL ACFT, FOR THAT MATTER), BECAUSE I BELIEVE ALL OF US ON AN IFR FLT PLAN ARE LULLED INTO A SMALL SENSE OF SECURITY (WHICH INCIDENTALLY IS A FALSE SECURITY). SECONDLY, I BELIEVE THE ATC SYS SHOULD BE IMPROVED, NOW! THE PUBLIC SHOULD BE MADE AWARE OF THE SITUATION IN ORDER THAT PUBLIC FUNDING FOR THE ATC IMPROVEMENTS MIGHT BE INITIATED (CERTAINLY WE WERE NEVER GET THE TRUST FUND MONIES RELEASED IN TIME TO MAKE A DIFFERENCE. FORTUNATELY, NOTHING RESULTED FROM THIS INCIDENT AND WE ARE ALL ALIVE TO WARN OTHERS FROM OUR EXPERIENCE.
