Narrative:

The first officer was flying and I was working the radios. I had checked on with augusta approach and was told to expect a visual approach to runway 35. Approach was also talking to a cessna who was on vectors for a practice approach to the ILS runway 35. Approach gave us a clearance to descend to 2700 ft and turn to a heading of 150 degrees and asked if we had the cessna in sight. I indicated that we had the traffic in sight. He said we were cleared for the visual approach to runway 35 'with reference' to the cessna traffic. I interpreted this to mean we were following the cessna who was also going to runway 35. We were traveling much faster as we entered the left downwind to follow the cessna. When we received a TA on the cessna, I told the first officer to widen out to stay clear of the cessna. Approach then asked where we were going. I explained that we were widening out our downwind and I suggested we could do a 360 degree turn on downwind. He said we were actually #1 for the approach and had us turn left to 090 degrees and maintain no higher than 2500 ft. We turned, passed under the cessna, and landed. The controller in this situation should have said that we were #1 for the approach when he initially cleared us for the approach.

Title: AT72 FLC INITIATES EVASIVE ACTION FROM C172 AHEAD ON APCH, NOT REALIZING THAT AGS APCH WANTED THE AT72 TO PROCEED INBOUND IN FRONT OF THE C172.

Narrative: THE FO WAS FLYING AND I WAS WORKING THE RADIOS. I HAD CHKED ON WITH AUGUSTA APCH AND WAS TOLD TO EXPECT A VISUAL APCH TO RWY 35. APCH WAS ALSO TALKING TO A CESSNA WHO WAS ON VECTORS FOR A PRACTICE APCH TO THE ILS RWY 35. APCH GAVE US A CLRNC TO DSND TO 2700 FT AND TURN TO A HDG OF 150 DEGS AND ASKED IF WE HAD THE CESSNA IN SIGHT. I INDICATED THAT WE HAD THE TFC IN SIGHT. HE SAID WE WERE CLRED FOR THE VISUAL APCH TO RWY 35 'WITH REF' TO THE CESSNA TFC. I INTERPED THIS TO MEAN WE WERE FOLLOWING THE CESSNA WHO WAS ALSO GOING TO RWY 35. WE WERE TRAVELING MUCH FASTER AS WE ENTERED THE L DOWNWIND TO FOLLOW THE CESSNA. WHEN WE RECEIVED A TA ON THE CESSNA, I TOLD THE FO TO WIDEN OUT TO STAY CLR OF THE CESSNA. APCH THEN ASKED WHERE WE WERE GOING. I EXPLAINED THAT WE WERE WIDENING OUT OUR DOWNWIND AND I SUGGESTED WE COULD DO A 360 DEG TURN ON DOWNWIND. HE SAID WE WERE ACTUALLY #1 FOR THE APCH AND HAD US TURN L TO 090 DEGS AND MAINTAIN NO HIGHER THAN 2500 FT. WE TURNED, PASSED UNDER THE CESSNA, AND LANDED. THE CTLR IN THIS SIT SHOULD HAVE SAID THAT WE WERE #1 FOR THE APCH WHEN HE INITIALLY CLRED US FOR THE APCH.
