THE TFC THE RPTR WAS FOLLOWING WENT 7 MI DOWNWIND AT 1500 FT BEFORE TURNING BASE. THE RPTR BEING AT THE STANDARD PATTERN ALT OF 1000 FT HAD TO TURN TOWARDS THE OTHER ACFT ON FINAL TO AVOID THE HILLS.

Narrative

WHILE ON THE DOWNWIND LEG FOR R TFC RWY 24; THE BONANZA THAT I WAS FOLLOWING HAD EXTENDED HIS DOWNWIND LEG AT LEAST 7 MI E OF THE ARPT. THE BONANZA WAS FLYING AT AN ESTIMATED ALT OF 1500 FT MSL AND WAS FLYING A PATTERN THAT WAS AT LEAST DOUBLE THE NORMAL DISTANCE FROM THE RWY AS A NORMAL DOWNWIND LEG. THE BONANZA APPEARED TO BE CLBING AS THOUGH IT WERE LEAVING THE TFC PATTERN. THE PATTERN THAT THE BONANZA WAS FLYING WAS PULLING MY ACFT OVER MOUNTAIN TERRAIN TO THE NE OF THE ARPT. IN ORDER TO AVOID THE TERRAIN I HAD TO MANEUVER MY ACFT TOWARDS THE FINAL APCH PATH WHICH CONFLICTED WITH THE BONANZA. THIS PROB WAS CAUSED BY THE BONANZA FLYING THE TFC PATTERN AT 1500 FT MSL INSTEAD OF THE STANDARD 1000 FT MSL LISTED AS THE APPROVED TFC PATTERN ALT FOR SINGLE ENG ACFT. AS THE BONANZA WAS AT A HIGHER ALT HE COULD CLR THE TERRAIN TO THE NE WITH SUFFICIENT CLRNC. BUT BEING AT 1000 FT MSL I HAD TO MANEUVER THE ACFT TO THE S; THUS INFRINGING ON THE FINAL APCH PATH OF THE RWY IN USE; RWY 24. THIS CAUSED ME TO GET WITHIN 700 FT VERTLY AND 1000 FT HORIZLY OF THE ACFT.
