## Discrepancy

LANDING GEAR WOULD NOT COME DOWN AND PILOT CARRIED OUT EMERGENCY GEAR EXTENSION PROCEDURE. LANDING WAS COMPETED WITHOUT INCIDENT. MX REPLACED THE LANDING GEAR CONTROL VALVE WITH NO FURTHER PROBLEMS.  3 DAYS PRIOR PILOT HAD REPORTED THAT GEAR WAS SLOWER THAN NORMAL TO EXTEND. NUMEROUS GEAR SWINGS CARRIED OUT BY MX AND CHECKED SERVICEABLE.  ACFT RELEASED TO SERVICE.
