UNAUTH TXWY TKOF BY A PVT GA PLT AT ILG; DE.

Narrative

I WAS INSTRUCTED BY GND CTL TO TAXI TO RWY 14 AT TXWY F3. FOR THE LAST 9+ YRS THAT I HAVE BEEN AT ILG; TO GET TO RWY 14 FROM MY HANGAR; IT WAS L ON TXWY G; R ON TXWY J; TO THE INTXN OF RWY 9/27 AND RWY 14/32; A DEP THAT I HAVE MADE MANY TIMES. DURING THE LAST SEVERAL MONTHS; THERE HAS BEEN A LOT OF CONSTRUCTION IN THAT AREA; WHICH IS NOW COMPLETE. AS I WAS TAXIING W ON TXWY G; THE GND CTLR TOLD ME TO HOLD SHORT OF TXWY J TO ALLOW A G4 TO TAXI TO RWY 9. AS THE JET WENT BY; I DID MY RUN-UP AND SWITCHED TO THE TWR. THE TWR TOLD ME I WAS CLRED FOR A RWY 14 DEP AT TXWY F3. DUE TO ALL THE CONSTRUCTION AND NEW BLACKTOPPED TXWY F; I THOUGHT I WAS ON RWY 14 AND DEPARTED (TXWY F NEVER WENT THAT FAR W BEFORE). AS I STARTED TO ROTATE; I REALIZED MY MISTAKE. MY CHOICE AT THAT POINT WAS TO CUT PWR AND BRAKE HARD OR CONTINUE TKOF. MY DECISION WAS TO CONTINUE TKOF; TURN SLIGHT L AND ALIGN WITH RWY 14. BEFORE MY RETURN TO ILG; I LOOKED AT MY TERMINAL PROCS; VOLUME 3 OF 4; EFFECTIVE FEB/THU/02; PAGE 316; ILG ARPT DIAGRAM AND SAW HOW IT HAD BEEN CHANGED. THE BOOK I WAS USING AT THE TIME OF DEP WAS MY FLT GUIDE WHICH DID NOT SHOW ANY OF THE CHANGES. CORRECTIVE ACTION: I WILL LOOK AT THE TERMINAL PROCS; IF PUBLISHED; AND IF NOT; ASK FOR PROGRESSIVE TAXI.
