## Discrepancy

(CAN) WHEN THE RUDDER BELLCRANK ASSEMBLY WAS REMOVED FOR INSPECTION, IT WAS NOTICED THERE WAS A DEEP PITTING AROUND THE ATTACHMENT BOLT HOLE.  THE CORROSION RADIATED OUT FROM THE HOLE TWO INCHES.  THIS LOCATION IS UNDER THE RUDDER TORQUE TUBE ATTACHMENT FITTING AND IS IMPOSSIBLE TO INSPECT WITH THE RUDDER ASSEMBLY INSTALLED.
