Narrative:

While en route from dut-sjn-4AC, climbing out of 6000 ft for 11500 ft, I contacted ZAB for advisories. They gave me a squawk code and I continued my climb. As I was passing through 7500 ft, I realized that they had not said 'cleared through class B airspace.' I know I was very close to the edge of the airspace (7000 ft). I asked center if I had violated the class B airspace, and after a moment he said that he had spoken with phx and they were 'aware' of my position. That worried me a little, so when I stopped at sjn for fuel I called phx TRACON on the phone and they told me they were not aware of any violations that morning. I was not concerned enough about my position relative to the class B airspace after contacting center for flight following and I was distraction by a radio that was acting funny. I really don't know if I clipped the corner of the class B airspace, but I was certainly very close. I will pay much closer attention in the future.

Title: C152 PLT HAD POSSIBLE INCURSION INTO PHX CLASS B AIRSPACE.

Narrative: WHILE ENRTE FROM DUT-SJN-4AC, CLBING OUT OF 6000 FT FOR 11500 FT, I CONTACTED ZAB FOR ADVISORIES. THEY GAVE ME A SQUAWK CODE AND I CONTINUED MY CLB. AS I WAS PASSING THROUGH 7500 FT, I REALIZED THAT THEY HAD NOT SAID 'CLRED THROUGH CLASS B AIRSPACE.' I KNOW I WAS VERY CLOSE TO THE EDGE OF THE AIRSPACE (7000 FT). I ASKED CTR IF I HAD VIOLATED THE CLASS B AIRSPACE, AND AFTER A MOMENT HE SAID THAT HE HAD SPOKEN WITH PHX AND THEY WERE 'AWARE' OF MY POS. THAT WORRIED ME A LITTLE, SO WHEN I STOPPED AT SJN FOR FUEL I CALLED PHX TRACON ON THE PHONE AND THEY TOLD ME THEY WERE NOT AWARE OF ANY VIOLATIONS THAT MORNING. I WAS NOT CONCERNED ENOUGH ABOUT MY POS RELATIVE TO THE CLASS B AIRSPACE AFTER CONTACTING CTR FOR FLT FOLLOWING AND I WAS DISTR BY A RADIO THAT WAS ACTING FUNNY. I REALLY DON'T KNOW IF I CLIPPED THE CORNER OF THE CLASS B AIRSPACE, BUT I WAS CERTAINLY VERY CLOSE. I WILL PAY MUCH CLOSER ATTN IN THE FUTURE.
