Narrative:
In VFR conditions while on an IFR flight plan, cleared for circling approach to runway 30. Was on the ILS runway 2 approach at 1000 ft MSL at the break-off. Handed off to local tower, who issued a left base entry to runway 30. No vector was given and we were unfamiliar with the airport. We mistook runway 34 for runway 30, and headed inbound for runway 34. Winds were 300 degrees at 22 KTS. I observed a right drift while holding on the final approach to runway 34. At 400 ft AGL, realized we were lined up for runway 34 instead of runway 30. Called tower and advised. Tower issued go around with left turn to downwind for runway 30. No heading given. Turned base and thought we lined up with runway 30, but it was runway 34 again. Advised tower and they issued a right downwind to runway 30. This time we became fully aware of the airport runway and located runway 30 downwind, then to base. There was substantial traffic in pattern. Controller got somewhat concerned about getting us down.

Title: AFTER BREAKING OFF AN ILS APCH, PLT OF BE36 IS CLRED FOR CIRCLE-TO-LAND MANEUVER. UNFAMILIAR WITH SAC, HE TWICE LINED UP WITH RWY 34 WHEN CLRED FOR AN APCH TO RWY 30.
Narrative: IN VFR CONDITIONS WHILE ON AN IFR FLT PLAN, CLRED FOR CIRCLING APCH TO RWY 30. WAS ON THE ILS RWY 2 APCH AT 1000 FT MSL AT THE BREAK-OFF. HANDED OFF TO LCL TWR, WHO ISSUED A L BASE ENTRY TO RWY 30. NO VECTOR WAS GIVEN AND WE WERE UNFAMILIAR WITH THE ARPT. WE MISTOOK RWY 34 FOR RWY 30, AND HEADED INBOUND FOR RWY 34. WINDS WERE 300 DEGS AT 22 KTS. I OBSERVED A R DRIFT WHILE HOLDING ON THE FINAL APCH TO RWY 34. AT 400 FT AGL, REALIZED WE WERE LINED UP FOR RWY 34 INSTEAD OF RWY 30. CALLED TWR AND ADVISED. TWR ISSUED GAR WITH L TURN TO DOWNWIND FOR RWY 30. NO HDG GIVEN. TURNED BASE AND THOUGHT WE LINED UP WITH RWY 30, BUT IT WAS RWY 34 AGAIN. ADVISED TWR AND THEY ISSUED A R DOWNWIND TO RWY 30. THIS TIME WE BECAME FULLY AWARE OF THE ARPT RWY AND LOCATED RWY 30 DOWNWIND, THEN TO BASE. THERE WAS SUBSTANTIAL TFC IN PATTERN. CTLR GOT SOMEWHAT CONCERNED ABOUT GETTING US DOWN.
