## Discrepancy

WHILE ON APPROACH, ALL 3 GEAR INDICATIONS WERE RED "UNSAFE".  THE CREW PERFORMED A MANUAL GEAR EXTENSION AND LANDED WITHOUT FURTHER INCIDENT, OTHER THAN THE GEAR DOORS BEING OPEN ON LANDING.  MAINTENANCE FOUND ALL POSITION/WARNING SENSORS AND THE DIMENSIONAL LIMITS OF THE PROXIMITY SENSORS WERE WITHIN AMM LIMITS. THE GEAR WAS SWUNG WITH NO DEFECTS.  MAINTENANCE REPLACED THE PSEU.
