WHILE ENTERING A NON CTLED ARPT TFC PATTERN ON A 45 DEG ANGLE; AN SMA PLT OBSERVED A CESSNA 182 ALSO ENTERING ON A 90 DEG ANGLE CAUSING HIM TO TAKE EVASIVE ACTION TO ASSURE SEPARATION. BOTH ACFT HAD PREVIOUSLY RPTED THEIR POS AND INTENTIONS; EVEN THOUGH THE C182 HAD NOT RPTED STARTING HIS ENTRY.

Narrative

I WAS RETURNING TO FTG FOLLOWING A SOLO AEROBATIC PRACTICE SESSION. AT A DISTANCE OF 12 NM FROM THE ARPT; I PICKED UP THE AWOS BROADCAST; THEN SWITCHED TO CTAF AT ABOUT 10 NM. THE FREQ WAS CONGESTED; WITH NEARLY CONSTANT POS RPTS OF ACFT IN THE PATTERN. AT 8 NM THERE WAS A PAUSE IN THE RADIO TFC; AND I RPTED IN AS FOLLOWS: 'FRONT RANGE TFC XA 8 SE; PLANNING A 45 DEG ENTRY TO R DOWNWIND; RWY 8; FRONT RANGE.' AT ABOUT 4 NM FROM THE ARPT; I HEARD A SKYLANE RPT IN '6 MI SW;' ALSO PLANNING A 45 DEG ENTRY TO R DOWNWIND FOR RWY 8. AT 3 NM FROM THE ARPT; I AGAIN RPTED; 'FRONT RANGE TFC; XA 3 SE; PLANNING A 45 DEG ENTRY TO R DOWNWIND; RWY 8; FRONT RANGE.' I RPTED MY POS A THIRD TIME WHEN STARTING THE 45 DEG ENTRY LEG; ABOUT 1.5 MI SE OF THE FIELD. THROUGHOUT THIS PERIOD; I WAS LOOKING AHEAD AND TO THE L IN ORDER TO LOCATE THE SKYLANE; BUT DID NOT SPOT HIM. SHORTLY AFTER I TURNED TOWARDS THE FIELD; ANOTHER CESSNA ANNOUNCED THAT HE WAS TURNING A R XWIND LEG OFF RWY 8. I SWITCHED MY PRIMARY SEARCH SCAN TO THE R; AND LOCATED THE XWIND CESSNA AFTER 5 OR 10 SECONDS. I THEN SWITCHED MY PRIMARY SEARCH SCAN BACK TO THE L; LOOKING FOR THE SKYLANE. I ROLLED OUT ONTO A MIDFIELD R DOWNWIND AT ABOUT 100 KIAS; AND ANNOUNCED MY POS AGAIN. THEN I SPOTTED THE SKYLANE AT MY 10 O'CLOCK POS; SAME ALT (6500 FT MSL); HEADING STRAIGHT N. (NOTE THAT A 45 DEG ENTRY TO R DOWNWIND FOR RWY 8 SHOULD BE FLOWN ON A HEADING OF 305 DEGS.) I ESTIMATE THAT THE SKYLANE WAS LESS THAN 1000 FT AWAY; AND WAS MOVING AFT IN MY FIELD OF VIEW. I IMMEDIATELY OPENED THE THROTTLE FULLY IN ORDER TO INCREASE SEPARATION; AND ROCKED MY WINGS TO HELP ENSURE THAT THE SKYLANE WOULD SEE ME. A FEW SECONDS LATER; THE SKYLANE ANNOUNCED THAT HE WAS TURNING DOWNWIND BEHIND 'THE GUY WHO JUST CUT INTO THE PATTERN.' I REPLIED THAT I HAD ANNOUNCED MY INTENTIONS AND THEN FLOWN THE CORRESPONDING PATTERN ENTRY. I WENT ON TO PERFORM A TOUCH AND GO AND THE SKYLANE LANDED; BOTH WITHOUT FURTHER INCIDENT. AT NO TIME DID THE SKYLANE BROADCAST ANY PART OF HIS N-NUMBER. I FEEL THAT THIS WAS CAUSED BY A BUSY ARPT TFC ENVIRONMENT; COUPLED WITH THE SKYLANE'S FAILURE TO FLY AN APPROPRIATE TFC PATTERN ENTRY. IT ALSO SEEMS LIKELY THAT THE SKYLANE EITHER DID NOT HEAR OR DID NOT UNDERSTAND MY POS RPTS.
