SFB LCL CTLR INSTRUCTS ACFT DOWNFIELD INTO POS WITH TFC DEPARTING FROM THE APCH END OF RWY RESULTING IN A RWY INCURSION.

Narrative

AT SFB; GND CTLR HAD 4 OTHER POS COMBINED WITH GND CTLR AT THE TIME. GND CTLR HAD 6-10 ACFT CALLING FOR TAXI. NORMAL PROC IS TO WRITE A HALF STRIP AND PLACE ON LCL CTLR BOARD; TAXI TO RWY 9L AT B1. WHEN SENDING ACFT TO INTXN OTHER THAN B1; TO NOTIFY LCL CTLR; OBTAIN ACKNOWLEDGEMENT AND WRITE INTXN AND RWY ON STRIP (GND CTLR NEVER OBTAINED ACKNOWLEDGEMENT. THE STRIP WAS PLACED IN BIN WITH OTHER STRIPS -- NO SPECIAL; I.E.; COCKING AND/OR UPSIDE DOWN TREATMENT OF THE STRIP.) TRYING TO DEPART AS MANY SMALL ACFT PRIOR TO HVY JET INBOUND. DEPARTED 1 ACFT; TAXIED ANOTHER INTO POS; ANOTHER CALLS INBOUND; ANOTHER CALLS READY; CLR #2; TAXIED INTO POS #3; #4 CALLS READY AT INTXN R (I DID NOT 'REGISTER 'R'). CLRED #3; AND TOLD #4 TO TAXI INTO POS AT 'B1' AND BE READY; HVY JET 6 MI FINAL. AT SAME TIME; RELIEVING CTLR WAS PLUGGED IN; AWAITING BRIEFING; WHICH WAS BEING DONE AS #4 TAXIED ONTO RWY AT 'R' (B1 TO R APPROX 6500 FT). #3 WAS AIRBORNE APPROX 3000 FT PRIOR TO INTXN. IF RELIEVING GND CTLR HAD BEEN ABLE TO PAY ATTN TO GND CTLR AND NOT ANSWERING PHONES; NOTAMS; ETC; AND HAD THEY GOT AN ACKNOWLEDGEMENT OR COCKED THE STRIP OR HIGHLIGHTED THE INTXN; IT COULD HAVE PREVENTED OCCURRENCE. HAD I 'HEARD' #4 CALL AT 'R;' IT WOULD NOT HAVE HAPPENED. HAD I SEEN 'R' SCRIBBLED ON STRIP; IT WOULD NOT HAVE HAPPENED. TOO MANY PEOPLE TRYING TO DO TOO MANY THINGS TOO FAST CONTRIBUTED. THE CIC (WHO WAS THE GND CTLR) WAS NOTIFIED.
