## Discrepancy

THE CREW REPORTED THAT DURING A NORMAL GEAR EXTENSION, THE NOSE WHEEL WOULD NOT EXTEND.  THE LANDING GEAR WAS CYCLED TWICE, AND THE NOSE GEAR REMAINED RETRACTED.  A MANUAL EXTENSION WAS PERFORMED, AND THE AIRCRAFT LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED THE LANDING GEAR SELECTOR VALVE.  OPERATIONAL AND LEAK CHECKS WERE GOOD.  EXTENSION AND RETRACTION CHECKS WERE PERFORMED WITH NO NOTED DEFECTS.  THE AIRCRAFT WAS RETURNED TO SERVICE.
