## Discrepancy

DURING APPROACH INTO ABY, THE NOSE GEAR FAILED TO EXTEND.  THE CAPTAIN ABORTED THE INITIAL APPROACH.  WHILE IN A HOLDING PATTERN, APPROXIMATELY 5 MINUTES AFTER BEING SELECTED DOWN, THE GEAR EXTENDED ON ITS OWN.  EVEN WITH THE GEAR SAFE INDICATIONS, A VIBRATIONS WAS STILL FELT COMING FROM THE NOSE AREA.  AN EMERGENCY WAS DECLARED AND AN UNEVENTFUL LANDING WAS MADE IN ABY.  MAINTENANCE REMOVED AND REPLACED THE NOSE LANDING GEAR NR 2 DOWNLOCK PROXIMITY SENSOR.  THE AIRCRAFT WAS JACKED, AND THE GEAR WAS SWUNG SEVERAL TIMES.  SYSTEM OPERATIONAL CHECKS GOOD.  NO DEFECTS WERE NOTED.  AIRCRAFT RETURNED TO SERVICE.  (M)
