Narrative:
On the ground at oak, I contacted ground and indicated that I was VFR to 201 gansner field, quincy, ca. Ground requested route of flight and altitude. I indicated V6 sac direct at 15500 ft. Ground provided a squawk code and taxi clearance. Holding short of runway 27R, I contacted the tower indicating that I was ready to go, holding short of runway 27R. The tower provided the following takeoff clearance: 'clear for takeoff on runway 27R, right crosswind departure, on course, approved.' on departure, I climbed straight to 800 ft MSL, then turned right, climbing and intercepted V6 continuing the climb. The tower contacted me with multiple targets, which I idented on TCASII, but did not have visual. I indicated that I was looking for traffic and continued to climb on course. Upon reaching 4000 ft MSL, the tower came on frequency using a very concerned voice and stated 'pilatus, you are climbing beyond your clearance of 2500 ft, descend immediately, you are entering class B airspace.' I immediately began a descent, and responded that I hadn't been given any altitude restr, and inquired what altitude they would like me to descend to. I was given 3000 ft by the tower controller. The controller then called with a frequency change to norcal departure, and indicated that they would have higher. Upon switching to norcal departure, I was cleared to climb on course to 15500 ft. While there was never a dangerous traffic conflict, there was obviously confusion, which could have led to a more serious situation. Interestingly, based on my TCASII output, the continued climb helped avoid the traffic that was being reported by the tower controller. There does not appear to be a clear procedure for managing VFR traffic, which is climbing rapidly from class C airspace into class B airspace at this particular location. I certainly believed that since I was in controled airspace with a transponder code and a clearance to depart on course, that I had no altitude restr and that the airspace transition would be handled by the controller.

Title: NEAR INTRUSION INTO CLASS B OF SFO BY A LOW TIME COMMERCIAL PLT IN A PILATUS PC12 4 NM NE OF OAK VOR, CA.
Narrative: ON THE GND AT OAK, I CONTACTED GND AND INDICATED THAT I WAS VFR TO 201 GANSNER FIELD, QUINCY, CA. GND REQUESTED RTE OF FLT AND ALT. I INDICATED V6 SAC DIRECT AT 15500 FT. GND PROVIDED A SQUAWK CODE AND TAXI CLRNC. HOLDING SHORT OF RWY 27R, I CONTACTED THE TWR INDICATING THAT I WAS READY TO GO, HOLDING SHORT OF RWY 27R. THE TWR PROVIDED THE FOLLOWING TKOF CLRNC: 'CLR FOR TKOF ON RWY 27R, R XWIND DEP, ON COURSE, APPROVED.' ON DEP, I CLBED STRAIGHT TO 800 FT MSL, THEN TURNED R, CLBING AND INTERCEPTED V6 CONTINUING THE CLB. THE TWR CONTACTED ME WITH MULTIPLE TARGETS, WHICH I IDENTED ON TCASII, BUT DID NOT HAVE VISUAL. I INDICATED THAT I WAS LOOKING FOR TFC AND CONTINUED TO CLB ON COURSE. UPON REACHING 4000 FT MSL, THE TWR CAME ON FREQ USING A VERY CONCERNED VOICE AND STATED 'PILATUS, YOU ARE CLBING BEYOND YOUR CLRNC OF 2500 FT, DSND IMMEDIATELY, YOU ARE ENTERING CLASS B AIRSPACE.' I IMMEDIATELY BEGAN A DSCNT, AND RESPONDED THAT I HADN'T BEEN GIVEN ANY ALT RESTR, AND INQUIRED WHAT ALT THEY WOULD LIKE ME TO DSND TO. I WAS GIVEN 3000 FT BY THE TWR CTLR. THE CTLR THEN CALLED WITH A FREQ CHANGE TO NORCAL DEP, AND INDICATED THAT THEY WOULD HAVE HIGHER. UPON SWITCHING TO NORCAL DEP, I WAS CLRED TO CLB ON COURSE TO 15500 FT. WHILE THERE WAS NEVER A DANGEROUS TFC CONFLICT, THERE WAS OBVIOUSLY CONFUSION, WHICH COULD HAVE LED TO A MORE SERIOUS SIT. INTERESTINGLY, BASED ON MY TCASII OUTPUT, THE CONTINUED CLB HELPED AVOID THE TFC THAT WAS BEING RPTED BY THE TWR CTLR. THERE DOES NOT APPEAR TO BE A CLR PROC FOR MANAGING VFR TFC, WHICH IS CLBING RAPIDLY FROM CLASS C AIRSPACE INTO CLASS B AIRSPACE AT THIS PARTICULAR LOCATION. I CERTAINLY BELIEVED THAT SINCE I WAS IN CTLED AIRSPACE WITH A XPONDER CODE AND A CLRNC TO DEPART ON COURSE, THAT I HAD NO ALT RESTR AND THAT THE AIRSPACE TRANSITION WOULD BE HANDLED BY THE CTLR.
