## Discrepancy

CREW REPORTED THAT THE NOSE LANDING GEAR DOORS STAYED OPEN AFTER TAKEOFF.  MAINTENANCE PLACED THE AIRCRAFT ON JACKS AND PERFORMED MULTIPLE GEAR SWINGS WITH NO DEFECTS NOTED OF THE EXTENSION AND RETRACTION SYSTEM.  NOTED THAT THE NOSE LANDING GEAR DOORS WERE CYCLING AND LOCKING UP AS REQUIRED.  AFTER FURTHER TROUBLESHOOTING, FOUND THE DOWNLOCK CONNECTOR CORRODED.  THE DOWNLOCK CONNECTOR WAS CLEANED AND OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECT NOTED.
