PART 135 ATX PLT LANDS AT TCB AND LATER FINDS OUT HE WAS SUPPOSED TO CONTACT NASSAU APCH.

Narrative

I WAS ON AN IFR FLT PLAN FROM JACKSONVILLE TO TREASURE CAY; BAHAMAS. MY COMPANY RECEIVED PRIOR PERMISSION FROM THE BAHAMIAN AUTH IN TREASURE CAY TO LAND AT THEIR ARPT AT APPROX XC00 LCL. I WAS STILL ON ZMA RADIO CTL UNTIL MY ACFT WAS ONLY 10 MI N OF THE AIRFIELD AND A DSCNT CLRNC DOWN TO 3000 FT. MY LAST REQUEST TO ZMA WAS 'XYZ HAS TREASURE CAY IN SIGHT. I NEED TO CANCEL IFR AT THIS TIME.' THE CTLR RESPONDED THAT CANCELLATION RECEIVED AND FREQ CHANGE APPROVED. SINCE ZMA DID NOT SAY TO CONTACT NASSAU APCH; I ASSUMED THAT I WAS CLRED TO SWITCH DIRECTLY OVER TO THE AIRFIELD UNICOM FREQ. SO I DID THIS AND LANDED INTO TREASURE CAY WITHOUT INCIDENT. LATER AT THE ARPT TERMINAL; A BAHAMAS ATC SUPVR CALLED ME ON THE PHONE TO THREATEN ME WITH VIOLATION BECAUSE I DID NOT CONTACT HIM ON THE RADIO FOR CLRNC PRIOR TO LNDG AT TREASURE CAY. (THE BAHAMAS ARE ONLY UNDER IFR RULES DURING NIGHT HRS.) I TRIED TO EXPLAIN TO HIM THAT I UNDERSTOOD FROM ZMA CTLRS THAT I WAS CLRED TO LAND AT THE AIRFIELD SINCE I WAS UNDER THEIR RADAR CTL UP UNTIL 10 MI FROM THE AIRFIELD AND THEY SUBSEQUENTLY ACCEPTED MY IFR CANCELLATION REQUEST AND DID NOT HAND ME OVER NASSAU. I APOLOGIZED TO HIM FOR THE MISUNDERSTANDING BUT HE WAS NOT VERY ACCEPTING. THE PURPOSE OF THE FLT WAS TO TRANSPORT 2 ACR MECHS TO TREASURE CAY TO REPAIR A DISABLED COMPANY ACFT.
