## Discrepancy

PILOT SELECTED GEAR DOWN ON LANDING. NLG DID NOT FULLY EXTEND FOLLOWED BY A HYD CAWS WARNING.  A FEW SECONDS LATER THE NOSE GEAR INDICATED DOWN AND THE PILOT LANDED UNEVENTFULLY.  A LANDING GEAR FUNCTION CHECK FOUND THE HYD DC ELECTRIC MOTOR SEIZED.  THE AIR INTAKE FAN SHROUD WAS OBSERVED TO BE BEATEN FROM THE INSIDE. THE MOTOR WAS REMOVED AND A 3/32 NUT WAS FOUND SHEARED, RATTLING AROUND IN THE FAN COMPARTMENT OF THE MOTOR.
