## Discrepancy

THE DOWNLOCK SWITCH ASSY WAS FOUND TO BE MISSING. THE ACTUATOR/LEVER THAT CONTACTS THE DOWNLOCK/UPLOCK WHEEL ON THE NLG DRAG BRACE. DURING GEAR EXTENSION FOR LANDING, THE PILOT FAILED TO GET A GREEN FOR THE NLG DOWN AND LOCKED. AFTER FLYING OUR AIRFIELD FOR VISUAL CONFIRMATION OF NLG DOWN AND LOCKED, THE ACFT LANDED WITHOUT FURTHER INCIDENT.
