Narrative:

Conducting visual approach into non radar airport with an operating control tower in VMC. As we turned a right base we were cleared to land. We heard tower working 2 other aircraft, a light single who was proceeding toward runway 6 and an army king air proceeding to the same runway as us. He had us and the king air in sight (apparently). He pointed us out to the king air who called us in sight and subsequently instructed the king air to follow us #2 to the runway. We acquired the single who was off to our right and would cross our path on short final due to the converging runway setup. When we acquired the king air we saw we were on converging paths, with us on a straight in final and the king air on a left base. As we were about to take evasive action the tower made the king air realize that he was screwing up upon which the king air rolled to the right which took him behind us eliminating the need for evasive action on our part. Apparently the king air either misjudged our distance or was looking at the single going to runway 6. The tower was on the ball and recognized the true nature of what was happening. I feel that with TCASII we would have acquired the king air sooner so that the king air would not have passed within 1/4 mi of us like he did. It is also worth noting that the lack of radar put the tower controller in a difficult situation.

Original NASA ASRS Text

Title: TFC PATTERN CONFLICT.

Narrative: CONDUCTING VISUAL APCH INTO NON RADAR ARPT WITH AN OPERATING CTL TWR IN VMC. AS WE TURNED A R BASE WE WERE CLRED TO LAND. WE HEARD TWR WORKING 2 OTHER ACFT, A LIGHT SINGLE WHO WAS PROCEEDING TOWARD RWY 6 AND AN ARMY KING AIR PROCEEDING TO THE SAME RWY AS US. HE HAD US AND THE KING AIR IN SIGHT (APPARENTLY). HE POINTED US OUT TO THE KING AIR WHO CALLED US IN SIGHT AND SUBSEQUENTLY INSTRUCTED THE KING AIR TO FOLLOW US #2 TO THE RWY. WE ACQUIRED THE SINGLE WHO WAS OFF TO OUR R AND WOULD CROSS OUR PATH ON SHORT FINAL DUE TO THE CONVERGING RWY SETUP. WHEN WE ACQUIRED THE KING AIR WE SAW WE WERE ON CONVERGING PATHS, WITH US ON A STRAIGHT IN FINAL AND THE KING AIR ON A L BASE. AS WE WERE ABOUT TO TAKE EVASIVE ACTION THE TWR MADE THE KING AIR REALIZE THAT HE WAS SCREWING UP UPON WHICH THE KING AIR ROLLED TO THE R WHICH TOOK HIM BEHIND US ELIMINATING THE NEED FOR EVASIVE ACTION ON OUR PART. APPARENTLY THE KING AIR EITHER MISJUDGED OUR DISTANCE OR WAS LOOKING AT THE SINGLE GOING TO RWY 6. THE TWR WAS ON THE BALL AND RECOGNIZED THE TRUE NATURE OF WHAT WAS HAPPENING. I FEEL THAT WITH TCASII WE WOULD HAVE ACQUIRED THE KING AIR SOONER SO THAT THE KING AIR WOULD NOT HAVE PASSED WITHIN 1/4 MI OF US LIKE HE DID. IT IS ALSO WORTH NOTING THAT THE LACK OF RADAR PUT THE TWR CTLR IN A DIFFICULT SIT.
