MLT REQUESTED AND TOLD EXPECT LEFT ILS. CTLR APPARENTLY PLANNED RIGHT ILS BUT NEVER CLARIFIED.

Narrative

WE WERE ON A PAX HAULING MISSION INTO MSP. WE REQUESTED 29L ON INITIAL CONTACT WITH APCH; AND WERE TOLD TO EXPECT IT. SWITCHING OVER TO FINAL APCH CTL; WE IMMEDIATELY RELIEVED VECTORS TO THE WEST. AFTER A COUPLE OF VECTORS; WE WERE TOLD 'TURN RIGHT TO 280 DEG; MAINTAIN 4000' UNTIL ESTABLISHED ON THE LOC; CLRED FOR THE APCH.' WE COMPLIED AND INTERCEPTED THE 29L LOC. APCH THEN CALLED TO REQUEST WE 'INTERCEPT THE LOC;' AND GAVE US A SLIGHT TURN TO THE RIGHT TO EXPEDITE. THE NEXT CALL WAS FOR A TURN FURTHER RIGHT AFTER HE EVIDENTLY REALIZED WE WERE NOT EXECUTING 29R AS HE EXPECTED. HE PASSED THE LOC FREQ AS 109.3 AND CLRED US TO INTERCEPT. THAT CAUSED CONFUSION UNTIL WE GOT OUT THE 29R APCH PLATE AND FOUND THE CORRECT FREQ OF 109.9. ONCE ESTABLISHED; NO FURTHER PROBLEMS RESULTED. THERE WAS VERY LITTLE TFC AT THE TIME. OUR NORMAL CREW OF FIVE IN THE COCKPIT WERE MONITORING THE RADIOS DURING APCH. WE WERE POSITIVE WE HAD NOT RECEIVED CLRNC FOR THE RIGHT; NOR HAD WE MISSED A CALL. IT WAS NOT BUSY. I BELIEVE THERE WAS A COMMUNICATION LAPSE BETWEEN THE TWO APCH CTLRS WE TALKED TO. ONE XMISSION BY THE CTLR DURING ANY OF THE APCH PHASE WITH THE MENTION OF 29R ADDED IN WOULD HAVE BROKEN THE CHAIN OF EVENTS. THIS IS MY ONLY SUGGESTION - SIMPLE. I NOW CONFIRM APCH CLRNCS WITH FINAL APCH; NO MATTER HOW LIGHT THE TFC LOADS APPEAR.
