FLT THROUGH TEMPORARY RESTR AREA.

Narrative

FLEW THROUGH THE TEMPORARY FLT RESTRICTION 24 NM OUT ON THE 183 DEG RADIAL OF THE SAN ANGELO VORTAC ENRTE TO SONORA; TX; AT 4500 FT MSL. I DID NOT KNOW ABOUT THE TEMPORARY FLT RESTRICTION UNTIL I RETURNED FROM THE FLT. WHEN I RECEIVED THE WX BRIEFING NO NOTAM WAS ISSUED TO ME; ALSO NO NOTAM WAS FOUND IN THE CURRENT NOTICES TO AIRMEN PUB. I ONLY DISCOVERED IT WHILE TALKING WITH ANOTHER PLT AFTER REACHING MY DEST. I BELIEVE THIS HAPPENED BECAUSE THE NOTAM SYS FAILED ME. THE NOTAM FOR THE TEMPORARY FLT RESTRICTION WAS NOT PUBLISHED IN THE NOTICES TO AIRMEN PUB; IT WAS FOUND IN THE ARPT/FACILITY DIRECTORY UNDER THE SPECIAL NOTICES SECTION. ALL TEMPORARY FLT RESTRICTIONS SHOULD BE PUBLISHED IN THE NOTICES TO AIRMEN PUB. IF THEY ARE NOT PUBLISHED IN THE NOTICES TO AIRMEN PUB THEN THE BRIEFER SHOULD TELL YOU ABOUT THE TEMPORARY FLT RESTRICTIONS ALONG YOUR RTE OF FLT DURING THE WX BRIEFING. I HAVE BECOME AWARE THAT THIS TEMPORARY FLT RESTRICTION HAS BEEN IN EFFECT FOR MANY YRS AND THE NOTICE IN THE ARPT/FACILITY DIRECTORY STATES 'UNTIL FURTHER NOTICE.' THIS SEEMS LIKE MORE OF A PERMANENT RESTRICTION TO FLT THAN TEMPORARY AND SHOULD BE PUBLISHED APPROPRIATELY (AS A RESTR AREA PLAINLY DISPLAYED ON THE CHART). THIS WOULD PREVENT FUTURE OCCURRENCES OF THIS NATURE!
