## Discrepancy

ON APPROACH TO BNA CREW  SELECTED LANDING GEAR DOWN. THE NOSE GEAR INDICATOR LIGHT DID NOT SHOW DOWN AND LOCK , CREW TESTED  LANDING GEAR INDICATOR LIGHT SYSTEM AND THE DOWN LOCK LIGHT (GREEN)  TESTED GOOD FOR NOSE GEAR SYSTEM . CREW NOTIFY ATC OF THEIR PROBLEM . ATC DIVERTED THEM TO MQT. CREW PERFORMED EMERGENCY GEAR EXTENSION PER AIRCRAFT FLIGHT MANUAL PROCEDURE AND STILL THEY DID NOT INDICATE NOSE GEAR DOWN AND LOCK. CREW PERFORMED A LOW PASS BY AIRPORT TOWER AND ASK THEM TO CHECK IF THEY CAN SEE IF THE NOSE LANDING GEAR WAS DOWN. TOWER NOTIFY THEM THAT THE LANDING GEAR LOOK DOWN.  CREW LANDED AIRCRAFT PER THE EMERGENCY GEAR UP PROCEDURE  PRE AIRCRAFT FLIGHT MANUAL JUST IN CASE THE NOSE LANDING WAS NOT LOCKED DOWN. AIRCRAFT LANDED SAFELY WITH NO LANDING GEAR PROBLEMS.  CAUSE OF LANDING GEAR LIGHT INDICATION  LIGHT PROBLEM WAS BROKEN WIRE TO TERMINAL BOARD FOR NOSE GEAR DOWN AND LOCK INDICATOR LIGHT SYSTEM
