MOONEY 20R PLT DEPARTS ARPT NEAR CANADIAN BORDER AND MAKES A L TURN VERSUS A R TURN AS HE CONTACTS CANADIAN ATC. THEY REMIND HIM OF THE CORRECT TURN DIRECTION AS THEY CLR HIM THROUGH THE AIRSPACE.

Narrative

AFTER DEPARTING ON RWY 32 AT SAULT STE MARIE; MI; I CLBED 500 FT AND WAS OVER THE DEP END OF THE RWY. AT THIS TIME I CONTACTED SAULT STE MARIE; CANADA; REQUESTING CLRNC THROUGH THEIR AIRSPACE AND STARTED A SHARP L TURN. AT THIS TIME SAULT STE MARIE; CANADA; TOLD ME THAT I WAS CLRED THROUGH THEIR AIRSPACE; AND THAT I WAS SUPPOSED TO MAKE A R TURN-OUT; NOT A L ONE WHEN DEPARTING RWY 32 AT SANDERSON. THIS WAS WHERE MY CONFUSION STARTED. ACCORDING TO MY GUIDE; R TFC WOULD BE FLOWN IF YOU WERE LNDG OR DEPARTING RWY 14; AND STANDARD L TFC FOR RWY 32. BECAUSE OF THIS I DEPARTED RWY 32 AT Y62 AND TURNED TO THE S (L) TO STAY AWAY FROM THE CLASS D AIRSPACE; AND THE UNITED STATES/CANADIAN BORDER. WHEN I RETURNED TO BTL AND LOOKED THROUGH THE AIRWAYS FACILITIES DIRECTORY I DISCOVERED THAT I HAD FLOWN AN IMPROPER TFC PATTERN. I COULD HAVE AVOIDED THIS INCIDENT BY CHKING OTHER REFS TO FIGURE OUT ANY SPECIFIC OR UNUSUAL PROCS FOR THIS ARPT (Y62); IE; CALL FBO; OR CHK ANY OTHER AIRWAYS FACILITIES DIRECTORY TYPE SOURCES. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT THE COMMERCIAL CHART IS DIFFERENT THAN THE SECTIONAL OR STATE CHARTS. THE COMMERCIAL GUIDE RPTR REFED IS AN ARPT FACILITY TYPE GUIDE. THE GOV ARPT FACILITY DIRECTORY DOES NOT MENTION A TURN OUT DIRECTION. HE INDICATED HE WOULD SEND A COPY OF THE ARPT FACILITY DIRECTORY WHICH SHOWS THE R TURN OUT. THIS WAS A FEW WKS AGO AND EVEN THOUGH HE RETURNED A CALL AND SAID WOULD GET TO IT; HE HAS NOT YET SENT THE COPY.
