## Discrepancy

DURING LEVELING A/C FOR WEIGHT AND BALANCE PURPOSES, GREEN SYS ELECT HYD PUMP WAS TURNED ON TO POSITION HORIZ STAB, A/C WAS BEING LEVELED USING 5 LANDING GEAR AXLE JACK POINTS, N/G STEERING SWITCH WAS SELECTED OFF AND N/G STEERING BY-PASS PIN INSTALLED.  AT THE MOMENT OF SYSTEM PRESSURIZATION NOSE LANDING IMMEDIATELY SWUNG 90 DEG.  T/S CARRIED OUT USING BITE INFO; AIRBUS INDUSTRIES WAS ALSO SOLICITED FOR ASSIST.  AN EXISTING TFU 32.51.00.020 DETAILS A SIMILAR PROBLEM.  A RECOMMENDATION WAS RECEIVED FROM AIRBUS TO REPLACE THE SELECTOR VALVE (FIN 5113GC) PRIOR TO NEXT FLT, WHICH WAS ACCOMP AND SENT UNIT OUT FOR ANALYSIS.  ADDITIONAL T/S RELATED TO A CLASS 3 FAULT THAT MAY BE RELATED REMAINS TO BE INVESTIGATED.
