Narrative:

On apr/sun/02, at around XA30, while en route from san carlos, ca, to santa monica, we were given a vector heading for 11 O'clock position traffic. I called the traffic in sight (an A320 airbus) about 12 mi out moving left to right. I acknowledged to maintain visual separation and the spacing was good. At that point the airbus made a hard right turn in our direction passing on our right side about 5 mi out. The captain of the airbus wanted the controller to save the tapes so he could file a complaint. At all times I had the airliner in sight. I feel that the captain never saw us and upon receiving a TCASII advisory, rather than change his altitude, he blindly turned into us. My corrective action was to turn slightly to the left. The aircraft were never closer than 5 mi to each other. Supplemental information from acn 545843: descending on bsr arrival with bay approach. Mutual traffic called at 1 O'clock position, 5 NM. We never saw aircraft. He told bay he had the airbus. Bay said to him to 'maintain visual separation' and cleared us to descend to 10000 ft MSL. Shortly after, we got a TCASII RA 'reduce descent.' green band between 0 and +/-1000 FPM. Disconnected autoplt and flew to -500 FPM. 5-7 seconds later we got 'climb, climb now.' full power and full aft stick applied. No green area until +3500 FPM climb. Navigation display was selected to 10 NM at first RA. Red square at 1 - 1:30 O'clock position and approximately 2 NM to 1.5 NM. Tracked right to us on a collision course. No change in clock position. I think the last number I saw was 300 ft below us. It could have been less. I told bay what happened and asked that the tapes be marked. Also, declared an near midair collision with them. Other aircraft failed to maintain visual separation with us!

Title: NMAC BTWN AN INBOUND DSNDING A320 ON THE BIGSUR ARR AND AN OUTBOUND CLBING C525 ON VECTOR VISUAL SEPARATION NEAR V25, S OF SKUNK INTXN, CA.

Narrative: ON APR/SUN/02, AT AROUND XA30, WHILE ENRTE FROM SAN CARLOS, CA, TO SANTA MONICA, WE WERE GIVEN A VECTOR HDG FOR 11 O'CLOCK POS TFC. I CALLED THE TFC IN SIGHT (AN A320 AIRBUS) ABOUT 12 MI OUT MOVING L TO R. I ACKNOWLEDGED TO MAINTAIN VISUAL SEPARATION AND THE SPACING WAS GOOD. AT THAT POINT THE AIRBUS MADE A HARD R TURN IN OUR DIRECTION PASSING ON OUR R SIDE ABOUT 5 MI OUT. THE CAPT OF THE AIRBUS WANTED THE CTLR TO SAVE THE TAPES SO HE COULD FILE A COMPLAINT. AT ALL TIMES I HAD THE AIRLINER IN SIGHT. I FEEL THAT THE CAPT NEVER SAW US AND UPON RECEIVING A TCASII ADVISORY, RATHER THAN CHANGE HIS ALT, HE BLINDLY TURNED INTO US. MY CORRECTIVE ACTION WAS TO TURN SLIGHTLY TO THE L. THE ACFT WERE NEVER CLOSER THAN 5 MI TO EACH OTHER. SUPPLEMENTAL INFO FROM ACN 545843: DSNDING ON BSR ARR WITH BAY APCH. MUTUAL TFC CALLED AT 1 O'CLOCK POS, 5 NM. WE NEVER SAW ACFT. HE TOLD BAY HE HAD THE AIRBUS. BAY SAID TO HIM TO 'MAINTAIN VISUAL SEPARATION' AND CLRED US TO DSND TO 10000 FT MSL. SHORTLY AFTER, WE GOT A TCASII RA 'REDUCE DSCNT.' GREEN BAND BTWN 0 AND +/-1000 FPM. DISCONNECTED AUTOPLT AND FLEW TO -500 FPM. 5-7 SECONDS LATER WE GOT 'CLB, CLB NOW.' FULL PWR AND FULL AFT STICK APPLIED. NO GREEN AREA UNTIL +3500 FPM CLB. NAV DISPLAY WAS SELECTED TO 10 NM AT FIRST RA. RED SQUARE AT 1 - 1:30 O'CLOCK POS AND APPROX 2 NM TO 1.5 NM. TRACKED R TO US ON A COLLISION COURSE. NO CHANGE IN CLOCK POS. I THINK THE LAST NUMBER I SAW WAS 300 FT BELOW US. IT COULD HAVE BEEN LESS. I TOLD BAY WHAT HAPPENED AND ASKED THAT THE TAPES BE MARKED. ALSO, DECLARED AN NMAC WITH THEM. OTHER ACFT FAILED TO MAINTAIN VISUAL SEPARATION WITH US!
