Narrative:

I am a tower controller at a VFR tower. I was working local control at XA00 local time. The conditions were a gray-blue sky making it hard to spot aircraft. At this time I had 2 small aircraft's and an small aircraft X in left closed traffic for runway 29. The approach control facility having IFR jurisdiction coordinated an medium large transport air carrier (air carrier Y) inbound from the southeast on a visibility approach to runway 29. Initial contact between Y and me occurred when the aircraft was on a 2 mi final. Conflicting traffic was small aircraft X on a 1/2 mi base to final. I instructed small aircraft X to fly north through final and reenter behind air carrier Y. After small aircraft X flew through final, he turned south and flew through air carrier Y's final again. Air carrier Y landed west/O incident. The pilot advised me that approach never transferred communication and decided to do it on his won. Result: 2 aircraft in close proximity of each other. Solution: in need of a tower radar scope. With this type of equipment, traffic could have been passed, approach could have been promoted to transfer communication and the landing sequence could have been changed.

Original NASA ASRS Text

Title: ACR CONTACTED TWR LATE, RESULTING IN THE CTLR TAKING ACTION TO RESEQUENCE AN SMA ON CLOSE FINAL.

Narrative: I AM A TWR CTLR AT A VFR TWR. I WAS WORKING LCL CTL AT XA00 LCL TIME. THE CONDITIONS WERE A GRAY-BLUE SKY MAKING IT HARD TO SPOT ACFT. AT THIS TIME I HAD 2 SMA'S AND AN SMA X IN LEFT CLOSED TFC FOR RWY 29. THE APCH CTL FAC HAVING IFR JURISDICTION COORDINATED AN MLG ACR (ACR Y) INBND FROM THE SE ON A VIS APCH TO RWY 29. INITIAL CONTACT BTWN Y AND ME OCCURRED WHEN THE ACFT WAS ON A 2 MI FINAL. CONFLICTING TFC WAS SMA X ON A 1/2 MI BASE TO FINAL. I INSTRUCTED SMA X TO FLY N THROUGH FINAL AND REENTER BEHIND ACR Y. AFTER SMA X FLEW THROUGH FINAL, HE TURNED S AND FLEW THROUGH ACR Y'S FINAL AGAIN. ACR Y LANDED W/O INCIDENT. THE PLT ADVISED ME THAT APCH NEVER TRANSFERRED COM AND DECIDED TO DO IT ON HIS WON. RESULT: 2 ACFT IN CLOSE PROX OF EACH OTHER. SOLUTION: IN NEED OF A TWR RADAR SCOPE. WITH THIS TYPE OF EQUIP, TFC COULD HAVE BEEN PASSED, APCH COULD HAVE BEEN PROMOTED TO TRANSFER COM AND THE LNDG SEQUENCE COULD HAVE BEEN CHANGED.
