## Discrepancy

(CAN) IN CRUISE, FLIGHT CREW STARTED TO SMELL SMOKE AND OBSERVED ARCING NEAR THE NOSEWHEEL STEERING SWITCH. CREW DONNED THEIR OXYGEN MASKS, DECLARED AN EMERGENCY AND DIVERTED TO A NEARBY AIRPORT. SHORTLY AFTER CIRCUIT BREAKER 4-C1 INST FLOOD LTG POPPED AND SMOKE DISSIPATED. AIRCRAFT LANDED WITHOUT FURTHER INCIDENT. UPON ARRIVAL THE AIRCRAFT WAS REMOVED FROM SERVICE AND LOCAL MAINTENANCE QUICKLY DETERMINED SMOKE/ARCING ORIGINATED FROM FLOOD LIGHT ASSEMBLY DS3LA LOCATED JUST ABOVE THE NOSEWHEEL STEERING SWITCH. THE LIGHTING SYSTEM WAS DEACTIVATED AND DEFERRED IN ACCORDANCE WITH MEL 33-11-01-1. THE ASSEMBLY WAS LATER REPLACED AND TESTED SERVICEABLE.
