## Discrepancy

CREW REPORTED, AFTER NUMEROUS ATTEMPTS TO LOWER THE GEAR, DID NOT RECEIVE 3 GREEN LIGHTS.  AN ALTERNATE EXTENSION WAS PERFORMED AND AIRCRAFT LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED BOTH MAIN LANDING GEAR DOWNLOCK SWITCHES, AND INSTALLED A NEW CONTROLLER.  OPERATIONAL CHECKS WERE GOOD.  PROBLEM HAD REOCCURRED DURING TEST FLIGHT.  MAINTENANCE REPLACED THE RIGHT MAIN LANDING GEAR DOWNLOCK ACTUATOR.  TEST FLIGHT WAS SATISFACTORY.  AIRCRAFT WAS RETURNED TO SERVICE.
