Narrative:

I was relieving sjt approach controller. There was a BE36 25 mi southwest of sjt wbound IFR at 7000 ft MSL (wrong altitude for direction of flight). Controller briefed that this altitude was requested by the pilot for WX. Controller advised ZFW had approved 7000 ft. At approximately XX55Z, ZFW called via hotline and advised that the BE36 needed to be climbed to 8000 ft for traffic in the military IR169 route southwest of san angelo. I had no strip on the aircraft at the time. I immediately asked X if he could accept 8000 ft. He responded in the affirmative. About this time, I heard a strip printing on the FD10. A few seconds later, the flight data controller brought the strip to me showing MTR Y, a T-38, on the IR169 route, eastbound with an altitude surface to 5000 ft. The actual assigned altitude for IR169 is surface to 7000 ft. Moments later I observed a target 6 mi west of san angelo airspace eastbound squawking the discrete beacon code of Y. Upon reviewing the strip, the IR169 entry time of Y indicated XX39Z approximately 20 mins earlier. Non radar separation requires protecting altitudes 10 mins in advance of an aircraft's estimated time at a fix. This was definitely not accomplished. Had X been at 6000 ft (correct altitude for direction) he would definitely not have been able to climb out of the IR169 in time to avoid an imminent situation. Non radar separation did not exist.

Title: POTENTIAL FOR LTSS ON IR RTE.

Narrative: I WAS RELIEVING SJT APCH CTLR. THERE WAS A BE36 25 MI SW OF SJT WBOUND IFR AT 7000 FT MSL (WRONG ALT FOR DIRECTION OF FLT). CTLR BRIEFED THAT THIS ALT WAS REQUESTED BY THE PLT FOR WX. CTLR ADVISED ZFW HAD APPROVED 7000 FT. AT APPROX XX55Z, ZFW CALLED VIA HOTLINE AND ADVISED THAT THE BE36 NEEDED TO BE CLBED TO 8000 FT FOR TFC IN THE MIL IR169 RTE SW OF SAN ANGELO. I HAD NO STRIP ON THE ACFT AT THE TIME. I IMMEDIATELY ASKED X IF HE COULD ACCEPT 8000 FT. HE RESPONDED IN THE AFFIRMATIVE. ABOUT THIS TIME, I HEARD A STRIP PRINTING ON THE FD10. A FEW SECONDS LATER, THE FLT DATA CTLR BROUGHT THE STRIP TO ME SHOWING MTR Y, A T-38, ON THE IR169 RTE, EBOUND WITH AN ALT SURFACE TO 5000 FT. THE ACTUAL ASSIGNED ALT FOR IR169 IS SURFACE TO 7000 FT. MOMENTS LATER I OBSERVED A TARGET 6 MI W OF SAN ANGELO AIRSPACE EBOUND SQUAWKING THE DISCRETE BEACON CODE OF Y. UPON REVIEWING THE STRIP, THE IR169 ENTRY TIME OF Y INDICATED XX39Z APPROX 20 MINS EARLIER. NON RADAR SEPARATION REQUIRES PROTECTING ALTS 10 MINS IN ADVANCE OF AN ACFT'S ESTIMATED TIME AT A FIX. THIS WAS DEFINITELY NOT ACCOMPLISHED. HAD X BEEN AT 6000 FT (CORRECT ALT FOR DIRECTION) HE WOULD DEFINITELY NOT HAVE BEEN ABLE TO CLB OUT OF THE IR169 IN TIME TO AVOID AN IMMINENT SIT. NON RADAR SEPARATION DID NOT EXIST.
