## Discrepancy

DURING MAINTENANCE BASE VISIT FOUND EMERGENCY LIGHT POWER SUPPLY NR 1 NOT WORKING PROPERLY, HAS MULTIPLE EMERGENCY LIGHTS OUT.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  REMOVED AND REPLACED THE NR 1 EMERGENCY LIGHT POWER SUPPLY AND NR 1 EMERGENCY BATTERY.  ALL CHECKS GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
