PLT OF AN SMA SINGLE ENG LAND ACFT NMAC WITH ANOTHER ACFT APCHING TO LAND AT AN UNCTLED ARPT.

Narrative

BEFORE TAKING OFF ON RWY 35 I OBSERVED 1 SMA SINGLE ENG LAND IN L TFC FOR RWY 5. I WAITED UNTIL HE WAS PAST THE INTXN ON HIS TOUCH AND GO THEN TOOK OFF. AFTER TKOF I MADE A R TURNOUT; CLBED AND TURNED DOWNWIND FOR 35. AS I TURNED BASE FOR 35 I DECIDED TO MAKE A W DEP FROM THE TFC PATTERN. MY DEP PATH WAS S OF AND PARALLEL TO THE TXWY. THIS PATH LED ALMOST OVER THE END OF RWY 5. THE TFC I WAS WATCHING WAS OVER THE DEP END OF RWY 5 AND WAS NOT A CONFLICT. I DID NOT OBSERVE ANOTHER SINGLE ENG LAND SMA ON HIGH CLOSE-IN L DOWNWIND FOR RWY 5. WHEN I OBSERVED THE SECOND SINGLE ENG LAND SMA MY HDG WAS 280 ALMOST ABEAM OF AND S OF THE APCH END OF RWY 5. THE SECOND SINGLE ENG LAND SMA WAS IN A L TURN ALMOST OVER THE NUMBERS AT 800 AGL. I PERCEIVE HE WAS DECONFLICTING WITH ME. MY ERRORS WERE: NOT FLYING A STANDARD DEP WHEN BRAKING OFF MY APCH TO RWY 35; AND FLYING A PATH WHICH INTERSECTED WITH THE APCH TO RWY 5. I BECAME DISORIENTED AND DIDN'T REALIZE THAT A PATH PARALLELING THE TXWY WOULD INTERSECT WITH THE APCH PATH TO RWY 5. THE WIND WAS OUT OF THE N AT 8 KTS.
