A NEWLY LICENSED C172 PLT CROSSES A RWY WITHOUT AUTH AND LATER ENTERS CLASS B AIRSPACE WITHOUT AUTH.

Narrative

LAST SUNDAY I TOOK MY FIRST FLT SINCE RECEIVING MY PVT PLT CERTIFICATE THE WK BEFORE. I JOINED A FLYING CLUB AND WAS TAXIING OUT OF THE PARKING AREA AT MONTGOMERY FIELD. ME: GND; THIS IS CESSNA XYZ; DO I NEED A CLRNC FOR DEP? GND: CESSNA XYZ; ARE YOU FLYING VFR? ME: YES; VFR. GND: YOU ONLY NEED CLRNC FOR IFR. ME: OK; I'M NEAR THE EXXON SIGN; REQUEST DEP RWY 28L PLEASE. I'M NOT COMPLETELY CLR ON THE EXACT WORDING; BUT BASICALLY I THINK SOMETHING LIKE 'STAND BY' WAS SAID. NEXT COMES THE NIGHTMARE FOR ME. HAVING SOME RADIO STATIC PROBS; I MAY HAVE MISSED ANOTHER ACFT'S CALL SIGN; BUT HEARD THE CTLR SAY FOLLOW THE CESSNA AHEAD; ETC. THINKING THAT SHE MEANT ME; I STARTED ROLLING. WHEN I GOT TO RWY 28L; I CALLED: GND; CAN I DO MY RUN-UP RIGHT HERE? GND: OK SIR; I'LL CANCEL YOUR INSTRUCTIONS. (APPROX WORDING.) AT THIS POINT I DIDN'T UNDERSTAND WHY MY TAXI INSTRUCTIONS WERE CANCELED; BUT THAT I WOULD PROBABLY UNDERSTAND AFTER MY RUN-UP. NOTICE THAT AT THIS POINT I DIDN'T REALIZE IT; BUT THE GND CTLR THOUGHT THAT I WAS STILL AT THE AREA OF THE EXXON SIGN. I STUPIDLY DIDN'T SAY THAT I WAS GOING ONTO THE TXWY WHEN SHE HAD SAID FOLLOW THE CESSNA; ETC. I FINISHED THE RUN-UP AND SAID: GND; XYZ WE'RE READY TO GO. AT THIS POINT; I WAS PERHAPS 35 FT FROM THE HOLD LINES NEXT TO THE THRESHOLD OF RWY 28L. I ONCE AGAIN DIDN'T DO AS I ALWAYS DO AT MY HOME ARPT WHICH IS TO SAY; 'HOLDING SHORT OF THE L' BEFORE I SAID 'WE'RE READY TO GO.' GND: CESSNA XYZ; TAXI TO RWY 28R. WITH ONLY A SLIGHT BIT OF HESITANCY; I ROLLED SAYING: XYZ. I ROLLED ACROSS THE ACTIVE RWY OBEYING INSTRUCTIONS IN MY MIND (MOMENTARILY FORGETTING THAT I WAS SUPPOSED TO HEAR 'CROSS RWY SUCH AND SUCH; HOLD SHORT OF THE OTHER RWY SUCH AND SUCH.') ME: XYZ HOLDING SHORT OF THE R BTWN RWYS. THERE WAS A DEAFENING HUSH UNTIL THE GND CTLR SAID: CESSNA XYZ; SIR YOU'RE NOT WHERE YOU'RE SUPPOSED TO BE. I WAITED A FEW MINS; GOT U-TURN INSTRUCTIONS; TOOK OFF ON THE L AFTER BEING TOLD TO CONTACT THE TWR AT A PARTICULAR PHONE NUMBER WHEN WE RETURNED. AFTER A DOWNWIND DEP; I WAS ATTEMPTING TO STAY CLR OF THE CLASS B AIRSPACE AROUND 10 MI OUT AND WAS CALLED BY THE TWR OF THE ARPT WHICH I HAD JUST DEPARTED. TWR: CESSNA XYZ; YOU'RE IN CLASS B AIRSPACE; TURN L IMMEDIATELY. ME: XYZ TURNING L. NOTHING MORE WAS SAID ON THE RADIO ABOUT MY DRIFTING INTO THE CLASS B AIRSPACE DURING THE FLT. WHEN I RETURNED TO MONTGOMERY FIELD; I CALLED THE TWR AND APOLOGIZED FOR DOING SUCH A STUPID THING ON THE RWY AND ON MY DEP. THE CTLR WAS VERY POLITE AND SAID THAT TFC CTL WOULD BE CALLING ME AT HOME TO DISCUSS THE MATTER. THE TWR MGR CALLED ME A FEW DAYS LATER WANTING TO CLR UP WHAT HAD TRANSPIRED AT THE ARPT AND SAID THAT SOCAL OR ANOTHER AGENCY WOULD BE CALLING ME ALSO. A WK LATER; I HAVE NOW RECEIVED 5 1/2 HRS OF TRAINING ON MONTGOMERY FIELD OPS AND AIRSPACE OP AROUND SAN CLASS B AIRSPACE.
