Narrative:

I was on a VFR flight from auburn, ca (aun) to san jose, ca (sjc), receiving flight following services along the route. As stockton approach handed me off to bay approach on 135.4, I was slowly descending through 6000 ft. I increased my rate of descent when bay requested to maintain at or below 5000 ft for traffic. About 5 NM ese of the livermore, ca (lvk) airport, bay issued a TA 10 O'clock and requested immediate descent to 3000 ft. I descended to 3000 ft at a rate greater than 1500 FPM. Both my passenger and I, an ATP-MEL and commercial helicopter pilot scanned not only our 10 O'clock but the full area. Arriving at 3000 ft, we found it -- at our 2 O'clock position: a mooney (possibly a cherokee), white/blue, was headed straight at us. Both aircraft took evasive action to the left. We were basically at the same altitude and missed by approximately 200 ft laterally. My immediate call to the controller was ignored. His next communication for me was several mins later, as I was approaching the sunol intersection, when he instructed me to contact stockton approach on 123.85. Since stockton is to the northeast of this sector of bay approach and I was leaving the sector to the southwest, I told him that I would be contacting bay approach on 121.3. He copied that.

Title: NMAC. VFR ACFT SEE AND AVOID.

Narrative: I WAS ON A VFR FLT FROM AUBURN, CA (AUN) TO SAN JOSE, CA (SJC), RECEIVING FLT FOLLOWING SERVICES ALONG THE RTE. AS STOCKTON APCH HANDED ME OFF TO BAY APCH ON 135.4, I WAS SLOWLY DSNDING THROUGH 6000 FT. I INCREASED MY RATE OF DSCNT WHEN BAY REQUESTED TO MAINTAIN AT OR BELOW 5000 FT FOR TFC. ABOUT 5 NM ESE OF THE LIVERMORE, CA (LVK) ARPT, BAY ISSUED A TA 10 O'CLOCK AND REQUESTED IMMEDIATE DSCNT TO 3000 FT. I DSNDED TO 3000 FT AT A RATE GREATER THAN 1500 FPM. BOTH MY PAX AND I, AN ATP-MEL AND COMMERCIAL HELI PLT SCANNED NOT ONLY OUR 10 O'CLOCK BUT THE FULL AREA. ARRIVING AT 3000 FT, WE FOUND IT -- AT OUR 2 O'CLOCK POS: A MOONEY (POSSIBLY A CHEROKEE), WHITE/BLUE, WAS HEADED STRAIGHT AT US. BOTH ACFT TOOK EVASIVE ACTION TO THE L. WE WERE BASICALLY AT THE SAME ALT AND MISSED BY APPROX 200 FT LATERALLY. MY IMMEDIATE CALL TO THE CTLR WAS IGNORED. HIS NEXT COM FOR ME WAS SEVERAL MINS LATER, AS I WAS APCHING THE SUNOL INTXN, WHEN HE INSTRUCTED ME TO CONTACT STOCKTON APCH ON 123.85. SINCE STOCKTON IS TO THE NE OF THIS SECTOR OF BAY APCH AND I WAS LEAVING THE SECTOR TO THE SW, I TOLD HIM THAT I WOULD BE CONTACTING BAY APCH ON 121.3. HE COPIED THAT.
