C177 PLT ENTERED LAS CLASS B WITH CLRNC.

Narrative

THE FLT WAS FROM GCN TO L15 (HENDERSON) VIA THE PEACH SPRING VOR. AROUND 20 MI SE OF HENDERSON I BEGAN MY DSCNT TO 4500 FT TO CLR THE RIDGE S OF THE ARPT. AROUND 10 MI SE OF THE ARPT I BEGAN MY ATTEMPTS TO ESTABLISH COM WITH HENDERSON TWR. I WAS NOT ABLE TO SAY MY CALLSIGN UNTIL 3 MI S OF THE ARPT; BUT DURING THAT TIME WAS ABLE TO DETERMINE THAT RWY 18 WAS IN USE. THERE WERE 3 PLANES AHEAD OF ME AND BY THE TIME I WAS 3 MI S OF THE ARPT; LINED UP FOR ENTERING DOWNWIND; THE TWR CALLED THE PLANE AHEAD OF ME TO MAKE A WIDE DOWNWIND. I FOLLOWED THE PLANE AHEAD OF ME AND BEGAN MY DSCNT TO PATTERN ALT OF 3300 FT. MIDFIELD OF THE DOWNWIND; I HEARD ON THE RADIO; 'ACFT X YOU ARE TOO HIGH AND IN CLASS B AIRSPACE'. I MADE A RUSHED DSCNT TO 3300 FT; TURNED BASE AND FINAL AND MADE AN EXTREMELY POOR LNDG. I KNEW ABOUT THE CLASS B AIRSPACE. I KNEW IT WAS 4000 FT STARTING 3 MI S AND 1 MI W OF THE ARPT. I BLUNDERED INTO IT ANYWAY. I HAD SUCCESSFULLY LANDED JUST 4 DAYS EARLIER AT HENDERSON SO I WAS FAMILIAR WITH THE AREA. THIS TIME; THE TFC AND COM LEVEL; ALTHOUGH NOT AT HIGH LEVELS; WAS ABOVE MY ABILITY TO HANDLE. I FORGOT TO DSND IN TIME. I BELIEVE I NEED MORE EXPERIENCE IN HIGH TFC AREAS. IF I CAN DO THIS SAFELY I WOULD BE VERY HAPPY.
