H25B LNDG TXK ISSUED VISUAL APCH CLRNC TO FOLLOW TFC IN THE PATTERN AND RESULTED IN GAR.

Narrative

LCL VISUAL APCHS WERE IN PROGRESS AT TXK. WHILE 5-10 NM FROM THE ARPT ZFW SEEMED CONFUSED ABOUT WHAT TFC WE WERE FOLLOWING ON APCH. ON A CLRNC OF DIRECT TO THE ARPT AND MAINTAIN 2500 FT MSL; WE WERE SETTING UP FOR A R BASE. AT A 4 MI R BASE WE WERE STILL SEVERAL THOUSAND FT AGL. BELIEVING I HAD BEEN CLRED FOR A VISUAL I DSNDED 400 FT. AT 2100 FT MSL WE WERE CLRED TO 2000 FT MSL. NOW ON A 3 NM R BASE WE WERE QUITE HIGH. ZFW TOLD US WE WERE TO FOLLOW AN ACFT ON FINAL BUT THEY SEEMED UNSURE OF ITS POS/INTENTION. WHEN CLRED FOR THE VISUAL WE ASKED IF WE SHOULD EXECUTE A 360 DEGS. THEY RESPONDED CLR FOR STRAIGHT IN. WE TURNED INBOUND ON A 2.5 NM FINAL. AFTER SWITCHING TO TWR; TWR INFORMED OF THE C182 ON A 1.5 NM FINAL. OUR TCASII DID NOT SHOW THIS TFC. WE IMMEDIATELY SPOTTED THE ACFT AFTER TWR MENTIONED IT AND WERE TOLD TO GO AROUND. WE EXECUTED AN UNEVENTFUL GAR. 4 CHAIN OF EVENTS PLAYED OUT HERE: 1) AT A 4-5 MI PROX FROM THE ARPT ZFW SEEMED CONFUSED ABOUT WHAT INSTRUCTIONS TO ISSUE FOR US. 2) MY BELIEF THAT AT THIS CLOSE PROX TO THE ARPT WE WERE CLRED FOR A VISUAL AND DSNDING 400 FT BELOW LAST CLRNC. 3) NO TCASII -- APPARENTLY THE C182 XPONDER WAS NOT ON. 4) POOR SEQUENCING BY ZFW; CONTRIBUTING TO OUR GAR.
