Narrative:

I was returning from a local flight over the corona, ca, area, and on the way back to torrance, ca, I may have inadvertently entered class B airspace in the los alamitos area. I was returning from corona on a heading of 238 degrees (U394) off the seal beach VOR. I was at 7000 ft, 5 mi west of corona, above a broken cloud deck. I contacted socal approach, told them my position, and they asked me to identify on VFR squawk 1200 after which they told me to contact another frequency as I was not in their area. I contacted the next controller but he was busy and was putting people on standby, me included. After a little while I tried to make contact again but he was still busy. By this time I was several miles along towards seal beach VOR and I had climbed up to 8300 ft to stay out of clouds. It was then that I realized I was approaching class B airspace which was between 7000 and 10000 ft. I was still VFR on top of a broken cloud deck. I immediately made a 90 degree right turn and rapidly descended to 3000 ft. On descent I believe I entered class B airspace just south of fullerton. My lapse in judgement at waiting for controller response was my fault. I am very familiar with this particular area and do realize how sensitive this area is. To my knowledge there was no conflict with other aircraft.

Title: PLT OF A MOONEY MO21 INADVERTENTLY ENTERED CLASS B AIRSPACE ENRTE TO HOME BASE. HE EXITED THE AIRSPACE IMMEDIATELY AFTER RECOGNIZING HIS ERROR.

Narrative: I WAS RETURNING FROM A LCL FLT OVER THE CORONA, CA, AREA, AND ON THE WAY BACK TO TORRANCE, CA, I MAY HAVE INADVERTENTLY ENTERED CLASS B AIRSPACE IN THE LOS ALAMITOS AREA. I WAS RETURNING FROM CORONA ON A HDG OF 238 DEGS (U394) OFF THE SEAL BEACH VOR. I WAS AT 7000 FT, 5 MI W OF CORONA, ABOVE A BROKEN CLOUD DECK. I CONTACTED SOCAL APCH, TOLD THEM MY POS, AND THEY ASKED ME TO IDENT ON VFR SQUAWK 1200 AFTER WHICH THEY TOLD ME TO CONTACT ANOTHER FREQ AS I WAS NOT IN THEIR AREA. I CONTACTED THE NEXT CTLR BUT HE WAS BUSY AND WAS PUTTING PEOPLE ON STANDBY, ME INCLUDED. AFTER A LITTLE WHILE I TRIED TO MAKE CONTACT AGAIN BUT HE WAS STILL BUSY. BY THIS TIME I WAS SEVERAL MILES ALONG TOWARDS SEAL BEACH VOR AND I HAD CLIMBED UP TO 8300 FT TO STAY OUT OF CLOUDS. IT WAS THEN THAT I REALIZED I WAS APCHING CLASS B AIRSPACE WHICH WAS BETWEEN 7000 AND 10000 FT. I WAS STILL VFR ON TOP OF A BROKEN CLOUD DECK. I IMMEDIATELY MADE A 90 DEG R TURN AND RAPIDLY DESCENDED TO 3000 FT. ON DESCENT I BELIEVE I ENTERED CLASS B AIRSPACE JUST S OF FULLERTON. MY LAPSE IN JUDGEMENT AT WAITING FOR CTLR RESPONSE WAS MY FAULT. I AM VERY FAMILIAR WITH THIS PARTICULAR AREA AND DO REALIZE HOW SENSITIVE THIS AREA IS. TO MY KNOWLEDGE THERE WAS NO CONFLICT WITH OTHER ACFT.
