LANDING GEAR WOULD NOT EXTEND NORMALLY.  THREE RED UNLOCKED INDICATORS REMAINED ILLUMINATED AFTER SELECTING GEAR DOWN.  PERFORMED EMERGENCY LANDING GEAR EXTENSION.  GEAR CAME DOWN NORMALLY AND 3 GREEN DOWN AND LOCKED INDICATION WITH NO RED UNLOCK LIGHTS ILLUMINATED.  LANDED NORMALLY WITHOUT FURTHER INCIDENT. MX FOUND BROKEN WIRE AT FRAME 27 HYD PUMP BAY TO PIN B AT 13GA LANDING GEAR SELECTOR VALVE. REPAIRED BROKEN WIRE AND PERFORMED NORMAL EXTENSION AND RETRACTION AND EMERGENCY EXTENSION FUNCTION AND FOUND BOTH TO PERFORM NORMALLY.
