## Discrepancy

(CAN) AFTER WATER LANDING PILOT EXPERIENCED LOSS OF WATER RUDDER STEERING CONTROL. MAINTENANCE INSPECTED THE AIRCRAFT AND FOUND THE TORQUE TUBE WHICH CONTROLS THE WATER RUDDER/TAIL WHEEL STEERING HAD SUFFERED A TORSIONAL SHEAR ACROSS THE TUBES DIAMETER AT ITS MIDWAY POINT. THE FAILURE WAS A DIRECT RESULT OF INTERNAL CORROSION ON THE TUBE.
