## Discrepancy

THE PILOT REPORTED ON FINAL, WHEN SELECTING THE LANDING GEAR TO THE DOWN POSITION THAT THE NOSE GEAR IN-TRANSIT LIGHT REMAINED ILLUMINATED. THE PILOT FOLLOWING PROCEDURES PERFORMED A MANUAL LANDING GEAR EXTENSION AND LANDED WITHOUT INCIDENT IN SXM.  MAINTENANCE INSPECTED THE AIRCRAFTS LANDING GEAR AND HYDRAULIC SYSTEM AND DISCOVERED THE LANDING GEAR SELECTOR VALVE TO BE WEAK CAUSING THE GEAR TO REMAIN IN TRANSIT FOR LONGER THAN NORMAL. MAINTENANCE REMOVED AND REPLACED THE SELECTOR VALVE  WITH A SERVICEABLE UNIT. THEN PERFORMED EXTENSION AND RETRACTION TEST. THE AIRCRAFT WAS CHECK FLOWN AND OPERATION OF THE LANDING GEAR AND INDICATION WAS NORMAL. THE AIRCRAFT WAS RETURNED TO SERVICE AND NO SUBSEQUENT ISSUES HAVE BEEN REPORTED.
