Narrative:

Upon arrival over lvm, I was given holding instruction for a skywest regional jet inbound on the approach into bzn. Crossing 13 mi east of the bzn field, I could see the whole airport. I turned on ASOS to get the latest WX, they called 100 ft broken, 3 mi. I couldn't cancel. I proceeded over the VOR and started outbound for manne (OM) to hold as published at 11000 ft. I continued to monitor the ASOS WX. Upon arrival at manne, the condition went VFR 8000 ft broken, 3 mi. At this point I canceled my IFR with center, they cleared me to bzn tower. I reported that I had just canceled with center and that I would go ahead and continue outbound for the procedure turn. Tower replied report a 4 mi final. I started my descent 11000 ft, only went outbound for 30 seconds or so and turned outbound on the procedure turn (all in VFR conditions) continuing to loose altitude and resetting bug's for a visual approach. I leveled off at 6800 ft, same as the instrument approach, turned back inbound for the airport. Found myself north of centerline for runway 12 and slowing to approach speed. I started to move south to join centerline when skywest called RA and started a climbing right turn. I proceeded in and found conditions approaching from the west to be marginal but VFR. There was a fog bank obstructing the approach end of runway 12, but could see the rest of the runway ok. I made a high approach to stay visual. Contributing factors: lack of center and inform me where skywest was on the approach. My assumption: I thought that skywest would have either been on short final or landing by the time I got to the OM. Also, reference my efc time would have expired. Within 2 mins of me reaching the OM, help me to believe he was further along than he was. My over-eagerness to get in. I was already 5 hours late, I shouldn't have canceled. Communication: I should have asked for their position, but was convinced he was further along.

Title: UNAWARE OF THEIR RELATIVE POS TO TFC AHEAD ON FINAL, FLC GAINED ON SAID TFC, CAUSING THAT TFC'S TCASII TO DISPLAY A CLB RA, RESULTING IN A GAR.

Narrative: UPON ARR OVER LVM, I WAS GIVEN HOLDING INSTRUCTION FOR A SKYWEST REGIONAL JET INBOUND ON THE APCH INTO BZN. XING 13 MI E OF THE BZN FIELD, I COULD SEE THE WHOLE ARPT. I TURNED ON ASOS TO GET THE LATEST WX, THEY CALLED 100 FT BROKEN, 3 MI. I COULDN'T CANCEL. I PROCEEDED OVER THE VOR AND STARTED OUTBOUND FOR MANNE (OM) TO HOLD AS PUBLISHED AT 11000 FT. I CONTINUED TO MONITOR THE ASOS WX. UPON ARR AT MANNE, THE CONDITION WENT VFR 8000 FT BROKEN, 3 MI. AT THIS POINT I CANCELED MY IFR WITH CTR, THEY CLRED ME TO BZN TWR. I RPTED THAT I HAD JUST CANCELED WITH CTR AND THAT I WOULD GO AHEAD AND CONTINUE OUTBOUND FOR THE PROC TURN. TWR REPLIED RPT A 4 MI FINAL. I STARTED MY DSCNT 11000 FT, ONLY WENT OUTBOUND FOR 30 SECONDS OR SO AND TURNED OUTBOUND ON THE PROC TURN (ALL IN VFR CONDITIONS) CONTINUING TO LOOSE ALT AND RESETTING BUG'S FOR A VISUAL APCH. I LEVELED OFF AT 6800 FT, SAME AS THE INST APCH, TURNED BACK INBOUND FOR THE ARPT. FOUND MYSELF N OF CTRLINE FOR RWY 12 AND SLOWING TO APCH SPD. I STARTED TO MOVE S TO JOIN CTRLINE WHEN SKYWEST CALLED RA AND STARTED A CLBING R TURN. I PROCEEDED IN AND FOUND CONDITIONS APCHING FROM THE W TO BE MARGINAL BUT VFR. THERE WAS A FOG BANK OBSTRUCTING THE APCH END OF RWY 12, BUT COULD SEE THE REST OF THE RWY OK. I MADE A HIGH APCH TO STAY VISUAL. CONTRIBUTING FACTORS: LACK OF CTR AND INFORM ME WHERE SKYWEST WAS ON THE APCH. MY ASSUMPTION: I THOUGHT THAT SKYWEST WOULD HAVE EITHER BEEN ON SHORT FINAL OR LNDG BY THE TIME I GOT TO THE OM. ALSO, REF MY EFC TIME WOULD HAVE EXPIRED. WITHIN 2 MINS OF ME REACHING THE OM, HELP ME TO BELIEVE HE WAS FURTHER ALONG THAN HE WAS. MY OVER-EAGERNESS TO GET IN. I WAS ALREADY 5 HRS LATE, I SHOULDN'T HAVE CANCELED. COM: I SHOULD HAVE ASKED FOR THEIR POS, BUT WAS CONVINCED HE WAS FURTHER ALONG.
