NMAC BTWN A C210 ENTERING AN UNCTLED TFC PATTERN AND A C152 ON XWIND DURING CLBOUT AFTER TKOF.

Narrative

FNL (UNCTLED) WAS HOSTING A SPECIAL EVENT ON 03/SAT/02. BECAUSE OF THAT; TFC WAS UNUSUALLY HVY. TFC WAS USING RWY 33. DUE TO TERRAIN; HOST FLTS ARE FAST OF THE ARPT; OPPOSITE FROM THE TFC PATTERN. AT THE CONCLUSION OF ONE FLT; I WAS INTENDING TO ENTER THE PATTERN FROM A MID FIELD XWIND. I ANNOUNCED THIS PLAN FROM 5E; 1E AND OVER THE ARPT. THE ONLY RESPONSE WAS FROM ANOTHER ACFT EXECUTING A SIMILAR PLAN (BEHIND ME). AT THE XWIND TO DOWNWIND TURN; SAW ACFT #2 PASS BELOW AND INSIDE OF #2. AFTER LNDG; PLT #2 CAME TO MY LOCATION. HE MADE COMMENTS WHICH I FELT WERE THREATENING. HE DID NOT APPEAR WILLING TO DISCUSS THIS. I REVIEWED THE AIM AFTER RETURNING HOME. THE CURRENT AIM RECOMMENDS A SINGLE PATTERN ENTRY; 45 DEGS MID FIELD DOWNWIND. I PLAN TO USE THAT ENTRY FOR FUTURE FLTS. THE FUNDAMENTAL PROBS WERE: TOO MANY ACFT COMING FROM TOO MANY DIRECTIONS; AND A LACK OF COM FROM SOME ACFT. THE LACK OF COM CANNOT BE RESOLVED SINCE NORDO ACFT ARE ALLOWED (IN THIS CASE; #2 WAS NOT NORDO). MERGING ACFT PRIOR TO PATTERN ENTRY WILL HELP TO ADDRESS THE FIRST PROB. REMINDING PLT TO COMMUNICATE WOULD HELP -- THEY SET AN EXAMPLE FOR BOTH NEW AND EXISTING PLTS.
