ZZZ DEVELOPMENTAL CTLR RECOGNIZES TAXIING ACFT HAS RPTED TAXIING FROM AN INCORRECTLY IDENTED ARPT FBO AND CORRECTS CLRNC TO HOLD SHORT OF RWY FOR DEPARTING TFC.

Narrative

ACFT #1 WAS GIVEN A TAXI CLRNC TO RWY 23 AFTER HE RPTED HIS POS WAS AT FBO-1. FBO-1 IS AN FBO AT ZZZ ARPT. IT IS LOCATED ON THE E SIDE OF THE AIRFIELD. THE APCH END OF RWY 23 IS ALSO LOCATED ON THE NE END OF THE FIELD. THERE ARE NO OTHER RWYS TO CROSS BTWN FBO-1 AND RWY 23. TXWY E PARALLELS THE RAMP AREA THAT LEADS INTO FBO-1 AND IS THE TXWY THAT LEADS TO THE APCH END OF RWY 23. ANOTHER ACFT THAT WAS GIVEN TAXI INSTRUCTIONS FROM FBO-1 TO RWY 23; WAS INSTRUCTED TO FOLLOW ACFT #1 (LR35) TO RWY 23. AT THIS TIME ACFT #1 INDICATED HE WAS ON THE W SIDE OF THE ARPT. ACFT #1 WAS INSTRUCTED IMMEDIATELY TO 'HOLD SHORT OF RWY 19 AT TXWY H.' ACFT #1 WAS OBSERVED JUST ENTERING ONTO TXWY H. HOWEVER; THERE WAS ANOTHER LEARJET (ACFT #2) DEPARTING RWY 19. BECAUSE OF ACFT #1'S ERRONEOUS POS RPT AND BECAUSE OF THE ZZZ ARPT'S MGMNT FAILURE TO TAKE ACTION ON THE FOLLOWING; THE POTENTIAL EXISTS FOR A CATASTROPHE. THERE WAS NO LOSS OF SEPARATION THIS TIME; BUT I BELIEVE THE POTENTIAL EXISTS EVERYDAY! FBO-1 IS AN FBO ON THE E SIDE OF CAK ARPT. THIS IS USUALLY REFERRED TO AS FBO E. THIS IS BECAUSE AT ONE TIME; FBO-1 WAS ALSO LOCATED ON THE WNW SIDE OF THE FIELD. THIS ONE NO LONGER EXISTS. THE FBO ON THE W SIDE NOW IS 'FBO-2.' IT IS MY UNDERSTANDING ACFT USING 'FBO-2' ARE INSTRUCTED TO SAY 'FBO-2' WHEN ASKED THEIR POS AND THERE ARE ALSO SIGNS INSTRUCTING THEM ALSO. HOWEVER; IT IS MY UNDERSTANDING THERE ARE SIGNS WITH 'FBO-1' ON THEM; STILL IN VIEW ON THE W SIDE. THESE 'OLD' SIGNS MISLEAD PLTS AS TO THEIR POS AND AS IN THE CASE BE GIVEN WRONG TAXI INSTRUCTIONS.
