## Discrepancy

AFTER LOWERING GEAR HANDLE, THE RIGHT GEAR DID NOT SHOW DOWN WITH GEAR DISAGREE MESSAGE.  LIGHTS CHECKED NORMAL,  CAME DOWN WITH ALTERNATE GEAR EXTENSION.  NO EMERGENCY WAS DECLARED AND THE FLIGHT LANDED WITHOUT FURTHER INCIDENT. THE AIRCRAFT WAS GROUNDED.  FOUND A HYDRAULIC LEAK ON THE RIGHT GEAR TRUCK POSITIONER PRESSURE LINE.  REPLACED THE LINE IAW AMM 20-10-10.
