## Discrepancy

REMOVED RUDDER TORQUE TUBE DUE TO ELONGATED HOLE AT BOTTOM FOR RUDDER HORN.  UPON DISASSEMBLY FOUND PART SEVERLY RUSTED AND CORROSION ON ADJACENT RIBS AND SKINS.  CAUSE FROM WATER ACCUMULATION AND POOR CORROSION PREVENTION ON PART.  NOTE:  SKINS AND RIBS HAD NO PRIMER AND THE TORQUE TUBE IS STEEL.
