Narrative:
Atx X departed runway 32 from pfn IFR to orlando. Atx X was assigned a departure heading of 360 degrees and an altitude of 3000 ft. Upon talking to tyndall RAPCON departure (1 mi north of pfn) atx X was told to proceed on course. Atx X turned to an approximately heading of 120 degrees at 1200 ft. This heading and altitude brought atx X through the traffic pattern for runway 32. No coordination for this turn had been effected as required by the pfn ATCT- tyndall LOA. The 120 degree heading also put atx X in a head-on conflict with small aircraft Y approximately 6 mi southeast of pfn who was IFR being vectored for a visual approach to runway 32. The local controller advised me of the situation and I called tyndall RAPCON to ask them if they turned atx X southeast. They advised me that they had. No coordination had been accomplished to bring small aircraft Y closer to the airport than 7 mi as required by the LOA. I advised tyndall of the conflict and they hung up. The local controller and I watched the situation on the tower BRITE radar. The 2 aircraft continued converging and when they passed each other they were approximately 4 mi southeast of pfn airport. According to the tower BRITE when they passed atx X was at 1800 ft and small aircraft Y was at 1500 ft. The lateral separation was about 1 mi. A follow-up investigation by the pfn ATCT air traffic manager and tyndall RAPCON concluded that visual separation was being applied by the pilots. I was given an opportunity to hear the tape recording of the situation. The pilot of small aircraft Y did report 'tally ho' when issued traffic on atx X ,however, the traffic call by the controller of '1 O'clock, 3 mi' is inconsistent with what I observed on the tower BRITE radar. According to the altitudes being reported by the pilot of atx X on the tape and what the local controller and I saw on the tower BRITE radar, it appears that a loss of IFR separation existed prior to the pilot of small aircraft Y reporting atx X in sight.

Title: NON COMPLIANCE WITH LOA ATX X UNAUTH UNCOORD TURN IN ATA. SYS ERROR.
Narrative: ATX X DEPARTED RWY 32 FROM PFN IFR TO ORLANDO. ATX X WAS ASSIGNED A DEP HDG OF 360 DEGS AND AN ALT OF 3000 FT. UPON TALKING TO TYNDALL RAPCON DEP (1 MI N OF PFN) ATX X WAS TOLD TO PROCEED ON COURSE. ATX X TURNED TO AN APPROX HDG OF 120 DEGS AT 1200 FT. THIS HDG AND ALT BROUGHT ATX X THROUGH THE TFC PATTERN FOR RWY 32. NO COORD FOR THIS TURN HAD BEEN EFFECTED AS REQUIRED BY THE PFN ATCT- TYNDALL LOA. THE 120 DEG HDG ALSO PUT ATX X IN A HEAD-ON CONFLICT WITH SMA Y APPROX 6 MI SE OF PFN WHO WAS IFR BEING VECTORED FOR A VISUAL APCH TO RWY 32. THE LCL CTLR ADVISED ME OF THE SIT AND I CALLED TYNDALL RAPCON TO ASK THEM IF THEY TURNED ATX X SE. THEY ADVISED ME THAT THEY HAD. NO COORD HAD BEEN ACCOMPLISHED TO BRING SMA Y CLOSER TO THE ARPT THAN 7 MI AS REQUIRED BY THE LOA. I ADVISED TYNDALL OF THE CONFLICT AND THEY HUNG UP. THE LCL CTLR AND I WATCHED THE SIT ON THE TWR BRITE RADAR. THE 2 ACFT CONTINUED CONVERGING AND WHEN THEY PASSED EACH OTHER THEY WERE APPROX 4 MI SE OF PFN ARPT. ACCORDING TO THE TWR BRITE WHEN THEY PASSED ATX X WAS AT 1800 FT AND SMA Y WAS AT 1500 FT. THE LATERAL SEPARATION WAS ABOUT 1 MI. A FOLLOW-UP INVESTIGATION BY THE PFN ATCT AIR TFC MGR AND TYNDALL RAPCON CONCLUDED THAT VISUAL SEPARATION WAS BEING APPLIED BY THE PLTS. I WAS GIVEN AN OPPORTUNITY TO HEAR THE TAPE RECORDING OF THE SIT. THE PLT OF SMA Y DID RPT 'TALLY HO' WHEN ISSUED TFC ON ATX X ,HOWEVER, THE TFC CALL BY THE CTLR OF '1 O'CLOCK, 3 MI' IS INCONSISTENT WITH WHAT I OBSERVED ON THE TWR BRITE RADAR. ACCORDING TO THE ALTS BEING RPTED BY THE PLT OF ATX X ON THE TAPE AND WHAT THE LCL CTLR AND I SAW ON THE TWR BRITE RADAR, IT APPEARS THAT A LOSS OF IFR SEPARATION EXISTED PRIOR TO THE PLT OF SMA Y RPTING ATX X IN SIGHT.
