LGT UNAUTH AIRSPACE ENTRY LATE FREQ CHANGE TO TWR.

Narrative

GJTT IS A NON RADAR APCH CTL FACILITY. THE LCL CTLR DOES NOT HAVE A BRITE RADAR TO ASSIST HIM IN SEQUENCING ARRIVING TFC; OR SEPARATING ARRIVING AND DEPARTING TFC. THERE ARE CERTAIN INDIVIDUALS IN THIS FACILITY WHO HAVE DEVELOPED A HABIT OF; WHEN WORKING APCH CTL; TRANSFERRING COMS OF ARRIVING IFR TFC WHEN THOSE ACFT HAVE ALREADY ENTERED THE LCL CTLR'S AIRSPACE. I.E.; ON DOWNWIND OR ON L/R BASE OR ON A 5 MI FINAL (FOR RWY 11; IF THE PLT IS READING HIS DME RATHER THAN ESTIMATING HIS DISTANCE; THAT WOULD BE 3 MI FROM THE APCH END OF THE RWY) OR OVER THE RIVER ON FINAL (FOR RWY 29 THE RIVER IS WITHIN 3.5 MI FROM THE APCH END). THIS SIT COULD BE VERY ACCEPTABLE AND EFFICIENT IF WE HAD A BRITE TO SEQUENCE TFC WITH; HOWEVER; BECAUSE OF THE LACK OF EQUIP TO DETERMINE THE POS OF INBOUND IFR ACFT; THIS SIT CREATES ADDITIONAL WORK FOR THE LCL CTLR AND COULD LEAD TO AN INCIDENT IF THE LCL CTLR IS NOT AWARE OF THE INBOUND TFC; AND ESPECIALLY IF THE LCL CTLR HAS TFC IN THE CLOSED TFC PATTERN. I.E.; I HAD AN SMA IN L CLOSED TFC TO RWY 22. THE APCH CTLR INSTRUCTED AN ACR TO 'CALL TWR ON DOWNWIND' AFTER THE APCH CTLR CLRED THE PLT FOR A VISUAL APCH TO RWY 29. THIS SIT COULD LEAD TO A SERIOUS PROB. THE LCL CTLR DOES NOT HAVE SUFFICIENT TIME TO ISSUE TA'S TO THE INBOUND ACFT NOR OTHER ACFT THAT HE MAY BE IN CONTACT WITH AT THE TIME. THE SAME CTLR INSTRUCTED A PREVIOUS ARRIVING ACFT TO CALL TWR OVER THE RIVER ON FINAL. SMT FROM THE SE. WHEN THE SMT HAD CALLED OVER THE RIVER; SMA HAD JUST TURNED HIS XWIND FOR RWY 22. IF THE SMA HAD BEEN FLYING A WIDE PATTERN; THIS SIT COULD HAVE RESULTED IN A SERIOUS PROB. TRANSFER OF COMS SHOULD BE IN ACCORDANCE WITH ATC MANUAL 7110.65 PARAGRAPH 2-14(A) AND PARAGRAPH 2-17(A).
