## Discrepancy

DURING PERFORMANCE OF C-CHECK INSPECTION TASK ON THE LEFT WING, THE AILERON ATTACH RIB 20 WAS FOUND TO HAVE A GOUGE APPROXIMATELY 1 INCH LONG BY .027 INCH DEEP ON THE OUTBOARD SIDE.  THIS WAS APPARENTLY CAUSED BY PREVIOUS REMOVAL OR INSTALLATION OF AILERON.  THE AREA OF DAMAGE IS HARD TO SEE WITH AILERON INSTALLED.
