PLT OF A BEECH KING AIR AFTER TOUCHING DOWN AT AN UNCTLED ARPT CAUSED 2 OTHER ACFT APCHING TO LAND IN THE OPPOSITE DIRECTION TO GAR. THE RPTR BASED THE WIND DIRECTION ON HIS LAST DEPARTED ARPT AND ANOTHER IN BTWN; WHICH WERE 60 AND 30 MI RESPECTIVELY.

Narrative

I WAS LNDG AT AN UNCTLED ARPT WHERE NO UNICOM IS IN SVC. THE ONLY ACTIVITY AT THIS PARTICULAR ARPT IS AN OCCASIONAL ACFT BEING BROUGHT INTO THE MAINT FACILITY LOCATED ON THE FIELD. THE RWY IS RWY 18/36. UPON CALLING BASE FOR RWY 18 AS KING AIR XXX; ANOTHER ACFT CALLED BASE FOR RWY 36 WITH AN N-NUMBER ONLY -- NOT TYPE. ON TURNING FINAL FOR RWY 18; THE OPPOSING ACFT CALLED FINAL FOR RWY 36. (I USED RWY 18 BECAUSE WIND DIRECTION AT MY DEP ARPT 60 MI AWAY WAS AND MY BRIEF FOR THE CLOSEST RPTING STATION 30 MI AWAY WAS FROM THE SW.) AT 1/2 MI FINAL; I SPOTTED A LNDG LIGHT 3 MI FROM THE DEP END OF RWY 18. THINKING I HAD PLENTY OF TIME AND KNOWING THE ARPT; I CONTINUED MY APCH. HOWEVER; PRIOR TO TOUCHDOWN; AN ACFT APPEARED ON SHORT FINAL FOR RWY 36 WHILE THE ACFT WITH THE LNDG LIGHTS ON WAS CONTINUING HIS APCH. IT BECAME APPARENT TO ME THE CLOSEST ACFT WAS THE ONE CALLING PATTERN; THE FURTHEST WAS SILENT. AS I TOUCHED DOWN; THE ACFT ON FINAL FOR RWY 36 (THE CLOSEST) CALLED GAR AND THE FURTHEST DID THE SAME. NOT KNOWING WHO IS IN THE WRONG OR RIGHT; ALL I CAN SUBMIT IS THAT GOOD COMS AND VIGILANCE IN LOOKING FOR TFC IS UTMOST IN UNCTLED FIELDS. P.S. I STARTED CALLING APCH TO THE FIELD 15 MI OUT AS I HAVE DONE SO FOR THE PAST 3 YRS.
