Narrative

AFTER COMPLETING A SCURRY 9 ARR TO MEACHAM ARPT WE WERE CLRED FOR A VISUAL APCH TO RWY 16L AND ADVISED TO CALL MEACHAM TWR; WHICH WE DID. TWR CLRED US TO LAND ON RWY 16L AND CALLED OUT TFC ON SHORT FINAL AND REQUESTED THAT WE HOLD OUR SPD DOWN. WE IDENTED THE TFC ON SHORT FINAL AND HELD OUR SPD BACK TO APPROX 125 KTS. AT THIS TIME WE NOTICED AN ACFT ON TKOF WHICH WOULD BE NO FACTOR. AT ABOUT THIS TIME I LOOKED TO THE RIGHT FRONT OF THE ACFT AND SAW AN SMA AT 2 O'CLOCK AND VERY CLOSE. I IMMEDIATELY TURNED TO THE LEFT AND CALLED FOR A MISSED APCH AND CLBED TO 2000' AND WAS ADVISED TO RETURN TO APCH CTL; WHICH WE DID; AND THEN VECTORED FOR ANOTHER LNDG ON THE SAME RWY W/O INCIDENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR STATES THAT TWR MADE NO COMMENT ABOUT THE SMA ACFT. WHEN QUESTIONED AFTER THE FACT STATED: 'OH; HE WAS PROBABLY CLRED FOR RWY 16R;' A RWY USED FOR TRNING AND GA SMA'S. SAYS WHEN SIGHTED THE ACFT FILLED THE ENTIRE WINDOW AREA AND REALLY SCARED THE CREW.
