## Discrepancy

DURING LANDING APPROACH TO PSC, LEFT MAIN LANDING GEAR WOULD NOT EXTEND.  AFTER SEVERAL ATTEMPTS, FLIGHT CREW LOWERED GEAR USING EMERGENCY GEAR EXTENSION SYSTEM.  LANDING GEAR PRESSURE REDUCER VALVE WAS FOUND TO BE THE CAUSE AND WAS SUBSEQUENTLY REPLACED.  AIRCRAFT RETURNED TO SERVICE.
