Narrative:

Air carrier X at 4000' northeast of airport being vectored to runway 28 ILS final approach course at syr. I requested the radar assistant to point out air carrier X to adjacent facility. I noticed a 4000' target ene of airport nwbnd, appeared to be ring-around. The radar assistant advised me to watch 4000' traffic from adjacent facility. Air carrier X was given descent to expedite to 3000' and issued traffic, '12 O'clock, 6 mi nwbnd, type unknown, altitude indicates 4000'.' descent was not adequate for sep, and air carrier X was given immediate left turn for traffic. Target then climbed to 5000'. I was then advised that the target was an light transport inbound for syr from utica west/O prior handoff or coordination--reason unknown. At no point was standard sep lost between the 2 aircraft. Supplemental information from acn 108454: cga, an light transport departed runway 27 at oneida county airport. I gave him a departure clearance to syr, 'turn right heading 300 degrees and climb and maintain 4000'.' he was then given a beacon code. Our ARTS iia system at our facility will not tag a departure aircraft if it is more than 5 mi from the airport when its transponder is turned on to the proper beacon code. This was the case with cga; he was outside the 5 mi range when he dialed in the beacon code and his target never acquired the ARTS identify tag. His untagged target went unnoticed till 5 mi inside adjacent facility's airspace. I gave him a climb to 5000' to ensure sep with pattern traffic at 4000' at syr and initiated a handoff. Sep was never lost. The lesson is never to become so dependent on any one aid in controling as to overlook others if this one fails.

Title: CGA PENETRATED ADJACENT FAC AIRSPACE WITHOUT HANDOFF.

Narrative: ACR X AT 4000' NE OF ARPT BEING VECTORED TO RWY 28 ILS FINAL APCH COURSE AT SYR. I REQUESTED THE RADAR ASSISTANT TO POINT OUT ACR X TO ADJACENT FAC. I NOTICED A 4000' TARGET ENE OF ARPT NWBND, APPEARED TO BE RING-AROUND. THE RADAR ASSISTANT ADVISED ME TO WATCH 4000' TFC FROM ADJACENT FAC. ACR X WAS GIVEN DSCNT TO EXPEDITE TO 3000' AND ISSUED TFC, '12 O'CLOCK, 6 MI NWBND, TYPE UNKNOWN, ALT INDICATES 4000'.' DSCNT WAS NOT ADEQUATE FOR SEP, AND ACR X WAS GIVEN IMMEDIATE LEFT TURN FOR TFC. TARGET THEN CLBED TO 5000'. I WAS THEN ADVISED THAT THE TARGET WAS AN LTT INBND FOR SYR FROM UTICA W/O PRIOR HDOF OR COORD--REASON UNKNOWN. AT NO POINT WAS STANDARD SEP LOST BTWN THE 2 ACFT. SUPPLEMENTAL INFO FROM ACN 108454: CGA, AN LTT DEPARTED RWY 27 AT ONEIDA COUNTY ARPT. I GAVE HIM A DEP CLRNC TO SYR, 'TURN RIGHT HDG 300 DEGS AND CLB AND MAINTAIN 4000'.' HE WAS THEN GIVEN A BEACON CODE. OUR ARTS IIA SYS AT OUR FAC WILL NOT TAG A DEP ACFT IF IT IS MORE THAN 5 MI FROM THE ARPT WHEN ITS XPONDER IS TURNED ON TO THE PROPER BEACON CODE. THIS WAS THE CASE WITH CGA; HE WAS OUTSIDE THE 5 MI RANGE WHEN HE DIALED IN THE BEACON CODE AND HIS TARGET NEVER ACQUIRED THE ARTS IDENT TAG. HIS UNTAGGED TARGET WENT UNNOTICED TILL 5 MI INSIDE ADJACENT FAC'S AIRSPACE. I GAVE HIM A CLB TO 5000' TO ENSURE SEP WITH PATTERN TFC AT 4000' AT SYR AND INITIATED A HDOF. SEP WAS NEVER LOST. THE LESSON IS NEVER TO BECOME SO DEPENDENT ON ANY ONE AID IN CTLING AS TO OVERLOOK OTHERS IF THIS ONE FAILS.
