## Discrepancy

THE NOSE GEAR UNSAFE LIGHT REMAINED ON AFTER GEAR RETRACTION WITH THE GEAR HANDLE IN THE UP POSITION.  THE CHECKLIST WAS RUN AND THE LIGHT BLINKED OFF AND ON INTERMITTENTLY.  THE LIGHT EXTINGUISHED AND REMAINED OUT AFTER ABOUT TEN MINUTES.  THE FLIGHT WAS CONTINUED TO EWR WHERE IT LANDED WITHOUT FURTHER PROBLEM.  THE PROXIMITY SWITCH CONTROL WAS REMOVED AND REPLACED.  INDICATIONS AND OPERATIONAL CHECKS WERE GOOD.
