## Discrepancy

(CAN) DURING TAKEOFF THE AIRCRAFT PULLED SLIGHTLY TO THE LEFT WHEN THE PILOT RELEASED THE NOSE GEAR STEERING BUTTON. AFTER TAKE OFF, THE CREW SELECTED GEAR UP AND THE NOSE GEAR IN TRANSIT LIGHT STAYED LIT. AN ATTEMPT TO LOWER THE GEAR NORMALLY AND USING THE EMERGENCY EXTENSION FAILED TO EXTINGUISH THE IN TRANSIT LIGHT AND THE NOSE GEAR STAYED IN THE WHEEL WELL. THE AIRCRAFT LANDED WITH THE NOSE GEAR RETRACTED. MAINTENANCE TRACED THE PROBLEM TO THE NOSE GEAR STEERING SERVO VALVE.
