Narrative:

I was on a VFR flight from O88 to sql. I am very familiar with this route, which is, after takeoff, to turn to a magnetic heading of approximately 198 degrees, call travis approach at 2000 ft for flight following and coordinate with bay approach for an arsa clearance through oakland's airspace, climb to 4500 ft, track inbound to oak VOR, expect 2000 ft crossing the VOR, be switched to oak north tower, then be switched again to oak south tower, descend to 1400 ft after crossing the shoreline, 'cross the mid-span of the san mateo bridge, squawk 1200, contact san carlos tower.' I was told to contact oak north tower on 118.30. I called north tower, confirmed that I would cross the runway 29 approach lights at 2000 ft, leveled off at 2000 ft about a mi before the approach lights. So far everything was normal. Just about the time that I was within a quarter mi or so from the middle of the runway 29 approach lights several things happened. First, I wondered why I hadn't yet been switched to the south tower. I looked to the south and saw a jet approaching oak. It appeared to be within 2 mi and slightly above my altitude. It appeared to enter a steep turn, and I have never seen an airliner do that before. I therefore added throttle to speed up, turned perpendicular to the runway (flew west a bit), and dove steeply out of any conceivable path of this jet. During this time, oak north tower finally handed me off to the south tower, but I was unable to raise them, and so I tried bay approach. I then switched back to oak south tower and this time I was able to make contact. I told them that I had been unsuccessful in raising them before. Oak south tower advised me of the small aircraft that was in front of me at 1300 ft and I acknowledged having it in sight. There was no mention of the jet at all. Oak south tower then had both of us (individually) squawk and told us each to contact san carlos.

Title: SMA X HAD CONFLICT WITH ACR IN OAK ARSA. EVASIVE ACTION TAKEN.

Narrative: I WAS ON A VFR FLT FROM O88 TO SQL. I AM VERY FAMILIAR WITH THIS RTE, WHICH IS, AFTER TKOF, TO TURN TO A MAGNETIC HDG OF APPROX 198 DEGS, CALL TRAVIS APCH AT 2000 FT FOR FLT FOLLOWING AND COORDINATE WITH BAY APCH FOR AN ARSA CLRNC THROUGH OAKLAND'S AIRSPACE, CLB TO 4500 FT, TRACK INBOUND TO OAK VOR, EXPECT 2000 FT XING THE VOR, BE SWITCHED TO OAK N TWR, THEN BE SWITCHED AGAIN TO OAK S TWR, DSND TO 1400 FT AFTER XING THE SHORELINE, 'CROSS THE MID-SPAN OF THE SAN MATEO BRIDGE, SQUAWK 1200, CONTACT SAN CARLOS TWR.' I WAS TOLD TO CONTACT OAK N TWR ON 118.30. I CALLED N TWR, CONFIRMED THAT I WOULD CROSS THE RWY 29 APCH LIGHTS AT 2000 FT, LEVELED OFF AT 2000 FT ABOUT A MI BEFORE THE APCH LIGHTS. SO FAR EVERYTHING WAS NORMAL. JUST ABOUT THE TIME THAT I WAS WITHIN A QUARTER MI OR SO FROM THE MIDDLE OF THE RWY 29 APCH LIGHTS SEVERAL THINGS HAPPENED. FIRST, I WONDERED WHY I HADN'T YET BEEN SWITCHED TO THE S TWR. I LOOKED TO THE S AND SAW A JET APCHING OAK. IT APPEARED TO BE WITHIN 2 MI AND SLIGHTLY ABOVE MY ALT. IT APPEARED TO ENTER A STEEP TURN, AND I HAVE NEVER SEEN AN AIRLINER DO THAT BEFORE. I THEREFORE ADDED THROTTLE TO SPD UP, TURNED PERPENDICULAR TO THE RWY (FLEW W A BIT), AND DOVE STEEPLY OUT OF ANY CONCEIVABLE PATH OF THIS JET. DURING THIS TIME, OAK N TWR FINALLY HANDED ME OFF TO THE S TWR, BUT I WAS UNABLE TO RAISE THEM, AND SO I TRIED BAY APCH. I THEN SWITCHED BACK TO OAK S TWR AND THIS TIME I WAS ABLE TO MAKE CONTACT. I TOLD THEM THAT I HAD BEEN UNSUCCESSFUL IN RAISING THEM BEFORE. OAK S TWR ADVISED ME OF THE SMA THAT WAS IN FRONT OF ME AT 1300 FT AND I ACKNOWLEDGED HAVING IT IN SIGHT. THERE WAS NO MENTION OF THE JET AT ALL. OAK S TWR THEN HAD BOTH OF US (INDIVIDUALLY) SQUAWK AND TOLD US EACH TO CONTACT SAN CARLOS.
