Narrative:

I was working west and south feeder/departure position combined plus sequencing arrs (both IFR and VFR). I was working 14 aircraft (4 VFR/10 IFR). I had a sequence set up for my arrs to runway 2 and had coordinated with the east feeder to use runway 34 for 2 other arrs, one an air carrier making an ILS and an small aircraft that was VFR. The situation was between an air carrier Y (light transport) and air carrier X (medium large transport). I had given air carrier Y a descent to 3000 from 9000. Air carrier Y had been given a 130 heading to follow air carrier Y and a descent to 5000 for sequence. There were 4 other aircraft already sequenced in front of air carrier Y, plus there was an small transport on downwind vector to follow air carrier X and an aircraft on an ILS vector to follow the small transport. I issued a turn to air carrier Y to follow air carrier Y and also a speed reduction back to 190 if feasible. (He was doing 270 KTS indicated at 6800 ft.) I was distracted from this situation by the small aircraft call 14 south of ric requesting landing instructions. This aircraft was just below air carrier. There was also an aircraft calling 20 northwest at 5500 VFR sebound. There isn't any doubt that if staffing would have allowed us (at ric) to have the final controller position open so my job as west and south feeder would have allowed me to concentrate on my duties instead of the responsibility of sequencing arrs plus my other duties this incident would never have occurred.

Title: LOSS OF SEPARATION OCCURRED BTWN AN LTT AND AN MLG ON FINAL APCH DUE TO TFC SPACING PROBLEM. LTSS.

Narrative: I WAS WORKING W AND S FEEDER/DEP POS COMBINED PLUS SEQUENCING ARRS (BOTH IFR AND VFR). I WAS WORKING 14 ACFT (4 VFR/10 IFR). I HAD A SEQUENCE SET UP FOR MY ARRS TO RWY 2 AND HAD COORDINATED WITH THE E FEEDER TO USE RWY 34 FOR 2 OTHER ARRS, ONE AN ACR MAKING AN ILS AND AN SMA THAT WAS VFR. THE SITUATION WAS BTWN AN ACR Y (LTT) AND ACR X (MLG). I HAD GIVEN ACR Y A DSCNT TO 3000 FROM 9000. ACR Y HAD BEEN GIVEN A 130 HDG TO FOLLOW ACR Y AND A DSCNT TO 5000 FOR SEQUENCE. THERE WERE 4 OTHER ACFT ALREADY SEQUENCED IN FRONT OF ACR Y, PLUS THERE WAS AN SMT ON DOWNWIND VECTOR TO FOLLOW ACR X AND AN ACFT ON AN ILS VECTOR TO FOLLOW THE SMT. I ISSUED A TURN TO ACR Y TO FOLLOW ACR Y AND ALSO A SPD REDUCTION BACK TO 190 IF FEASIBLE. (HE WAS DOING 270 KTS INDICATED AT 6800 FT.) I WAS DISTRACTED FROM THIS SITUATION BY THE SMA CALL 14 S OF RIC REQUESTING LNDG INSTRUCTIONS. THIS ACFT WAS JUST BELOW ACR. THERE WAS ALSO AN ACFT CALLING 20 NW AT 5500 VFR SEBOUND. THERE ISN'T ANY DOUBT THAT IF STAFFING WOULD HAVE ALLOWED US (AT RIC) TO HAVE THE FINAL CTLR POS OPEN SO MY JOB AS W AND S FEEDER WOULD HAVE ALLOWED ME TO CONCENTRATE ON MY DUTIES INSTEAD OF THE RESPONSIBILITY OF SEQUENCING ARRS PLUS MY OTHER DUTIES THIS INCIDENT WOULD NEVER HAVE OCCURRED.
