## Discrepancy

WHILE COMPLYING WITH SB (RUDDER TORQUE TUBE INSPECTION), RUST WAS FOUND ON THE INTERIOR AND EXTERIOR OF THE TORQUE TO BE INSIDE AND OUTSIDE THE RUDDER.  THIS PROBLEM MAY HAVE BEEN PREVENTED WITH BETTER INTERNAL AND EXTERNAL PAINT AND RUST CONTROL.  DRAIN HOLES WOULD HAVE HELPED IN THE LOWER RUDDER RIBS.
