## Discrepancy

WHEN THE GEAR WAS LOWERED AGAIN NORMAL INDICATION WAS RECEIVED AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  TROUBLESHOOTING FOUND THE NOSE LANDING GEAR CONTROL VALVE OUT OF ADJUSTMENT.  THE LANDING GEAR CONTROL VALVE WAS ADJUSTED IAW MM 32-31-00, PAGES 501-504.  OPERATIONAL CHECKS WERE GOOD.
