## Discrepancy

CREW REPORTED THAT AFTER TAKEOFF THE NOSE LANDING GEAR DOORS DID NOT CLOSE UNTIL 9000 FEET.  ALL LANDING GEAR INDICATIONS WERE NORMAL.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE NOSE LANDING GEAR SEQUENCE PROXIMITY SWITCH AND RELAY K0642.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
