## Discrepancy

FOUND THE RUDDER TORQUE TUBE AND WELDED ON ASSEMBLIES VERY CORRODED.  THE WELDED ON PLATE IS ABOVE THE BOTTOM RIB ON THE RUDDER AND CAN ONLY BE SEEN THROUGH A SMALL CUT-OUT IN THE RIB WHERE THE TORQUE TUBE PASSES THROUGH.  THE BOTTOM RIB (PN 40039-00) WAS ALSO UNAIRWORTHY DUE TO CORROSION.
