Narrative:
Small transport X was on a vector of 090 degree for the ILS runway 06 approach into abe approximately 19-20 mi southwest of etx VORTAC. The small transport Y was an IFR departure from 1n9 located approximately 6 mi southeast of etx VORTAC. Small transport X was level at 5000' and small transport Y was climbing out of 3000' to 8000' swbnd direct to lrp VORTAC. It soon became apparent that the two aircraft would come close to each other and vectors for avoidance were issued. Small transport X was given a 360 degree heading and small transport Y was given a 200 degree heading. Both aircraft passed each other and small transport X was given vectors for holding at the FAF for the number 2 sequence slot on the approach. FAA flight check operations were in progress below holding up arrs on the ILS approach. Small transport Y was returned to an on-course heading direct lrp and switched to ZNY center control for higher climb. It could not be determined if this was an 80 percent error at the time of this report. It is my belief that it is. I was working approximately 5 aircraft at the time. The position had just been decombined approximately 5 mins prior to the incident and there were several aircraft that had not yet been switched to the other sectors frequency. This was in addition to the 5 that I was working. We were also experiencing problems with the fdio computer in not receiving all flight information on all aircraft coming into the abe airspace. The primary aircraft involved, small transport X, was also a manual handoff from harrisburg approach to me because the flight had tagged as another aircraft even though it was displaying the correct transponder code. All of the above factors helped to add to the complexity of the current situation and was one of the main reasons the position was decombined.

Title: APCH CTLR CLIMBED SMT OFF SATELLITE ARPT THOUGH ALT OF SMT ARRIVAL WITH LESS THAN STANDARD SEPARATION.
Narrative: SMT X WAS ON A VECTOR OF 090 DEG FOR THE ILS RWY 06 APCH INTO ABE APPROX 19-20 MI SW OF ETX VORTAC. THE SMT Y WAS AN IFR DEP FROM 1N9 LOCATED APPROX 6 MI SE OF ETX VORTAC. SMT X WAS LEVEL AT 5000' AND SMT Y WAS CLBING OUT OF 3000' TO 8000' SWBND DIRECT TO LRP VORTAC. IT SOON BECAME APPARENT THAT THE TWO ACFT WOULD COME CLOSE TO EACH OTHER AND VECTORS FOR AVOIDANCE WERE ISSUED. SMT X WAS GIVEN A 360 DEG HDG AND SMT Y WAS GIVEN A 200 DEG HDG. BOTH ACFT PASSED EACH OTHER AND SMT X WAS GIVEN VECTORS FOR HOLDING AT THE FAF FOR THE NUMBER 2 SEQUENCE SLOT ON THE APCH. FAA FLT CHK OPS WERE IN PROGRESS BELOW HOLDING UP ARRS ON THE ILS APCH. SMT Y WAS RETURNED TO AN ON-COURSE HDG DIRECT LRP AND SWITCHED TO ZNY CTR CTL FOR HIGHER CLB. IT COULD NOT BE DETERMINED IF THIS WAS AN 80 PERCENT ERROR AT THE TIME OF THIS RPT. IT IS MY BELIEF THAT IT IS. I WAS WORKING APPROX 5 ACFT AT THE TIME. THE POS HAD JUST BEEN DECOMBINED APPROX 5 MINS PRIOR TO THE INCIDENT AND THERE WERE SEVERAL ACFT THAT HAD NOT YET BEEN SWITCHED TO THE OTHER SECTORS FREQ. THIS WAS IN ADDITION TO THE 5 THAT I WAS WORKING. WE WERE ALSO EXPERIENCING PROBS WITH THE FDIO COMPUTER IN NOT RECEIVING ALL FLT INFO ON ALL ACFT COMING INTO THE ABE AIRSPACE. THE PRIMARY ACFT INVOLVED, SMT X, WAS ALSO A MANUAL HDOF FROM HARRISBURG APCH TO ME BECAUSE THE FLT HAD TAGGED AS ANOTHER ACFT EVEN THOUGH IT WAS DISPLAYING THE CORRECT XPONDER CODE. ALL OF THE ABOVE FACTORS HELPED TO ADD TO THE COMPLEXITY OF THE CURRENT SITUATION AND WAS ONE OF THE MAIN REASONS THE POS WAS DECOMBINED.
