A C172 CFI RPTED AN ENCOUNTER AT 102 WITH AN AGGRESSIVE BEECH PLT.

Narrative

WE WERE APCHING THE FIELD FROM THE NNE TO OVERFLY N TO S FOR A WIND CHK BEFORE ENTERING THE TFC PATTERN AT LAMPSON FIELD. ONE OTHER ACFT HAD CHKED IN A BONANZA RPTING 10 MI N INBOUND FOR 45 DEG ENTRY TO R DOWNWIND ON RWY 28; APPROX 2-3 MINS PRIOR. AS WE REACHED OVERHEAD (2900 FT MSL); WE HEARD THE BONANZA RPT 'ENTERING THE 45.' AS MY STUDENT BEGAN A TURN BACK TO THE N TO SET UP FOR OUR ENTRY TO THE PATTERN; I QUERIED THE BONANZA FOR ALT. THE RESPONSE WAS; 'WHAT DOES IT MATTER TO YOU?' I FOOLISHLY DECLINED TO ANSWER THE QUESTION. WE SAW THE BONANZA AS WE CONTINUED THE TURN. HE WAS ON THE DOWNWIND AT WHAT APPEARED TO BE PATTERN ALT; 500 FT BELOW US. WE CLRED THE PATTERN TO THE N; DSNDED TO PATTERN ALT; AND ENTERED ON THE 45-TO-DOWNWIND FOR R TFC RWY 28. MY STUDENT WAS HANDLING THE RADIOS AT THIS POINT; AND BOTH HE AND THE BONANZA WERE MAKING STANDARD RPTS. WE ENTERED THE DOWNWIND AS THE BONANZA ROLLED FINAL. THE BONANZA LANDED AND STOPPED APPROX MIDFIELD; AND STATED HIS INTENT TO MAKE A 180 DEG TURN; AND EXIT THE RWY AT THE NEAREST TXWY. AT THIS POINT; WE CAME ABEAM THE APCH-END NUMBERS; AND MY STUDENT RETARDED THE PWR FOR DSCNT; AND CONTINUED FOR PERHAPS 3/4 MI BEFORE TURNING BASE. AS WE ROLLED LEVEL ON BASE; I COULD SEE THE BONANZA BACK TAXIING; AND ALMOST TO THE INTXN. I CONSIDERED THE BONANZA TO BE NO FACTOR. MY STUDENT TURNED FINAL A BIT TOO EARLY AND UNDERSHOT THE RWY CTRLINE; RESULTING IN WHAT LOOKED TO BE AN OBLIQUE-TO-FINAL. AS HE DID THIS; A VOICE ON THE RADIO SAID; 'THAT'S A PRETTY UNUSUAL BASE THERE CESSNA; YOU WANT TO GO AROUND?' I LOOKED UP TO SEE THE V-TAIL BONANZA STOPPED; WAITING ON THE RWY AT THE INTXN. TOO STUNNED TO REACT; I ALLOWED US TO CONTINUE TO SHORT FINAL; AS THE BONANZA SAT THERE. MY STUDENT MADE NO EVASIVE ACTION. ON SHORT FINAL; I COMMANDED A GAR; WHICH MY STUDENT EXECUTED. AS WE OVERFLEW THE RWY; I LOST SIGHT OF THE BONANZA; BUT PICKED HIM UP AGAIN; TAXIING TO PARKING; AS WE LEVELED ON THE DOWNWIND. AFTER WE HAD LANDED AND WERE CLR OF THE RWY; I ASKED MY STUDENT WHY HE HAD CONTINUED ON THE APCH EVEN AFTER THE BONANZA PLT HAD MADE CLR HIS INTENT TO REMAIN ON THE RWY. MY STUDENT (A POST-SOLO STUDENT PLT) REPLIED THAT; UNTIL A SHORT WHILE AFTER I COMMANDED THE GAR; HE WAS UNAWARE THAT THE BONANZA WAS THERE.
