## Discrepancy

THE CREW FOUND THAT THE EMERGENCY LIGHTS AT ROWS 7,8, AND 9 WOULD NOT ILLUMINATE.  MAINTENANCE INSPECTED AND FOUND THAT THE EMERGENCY POWER SUPPLY WAS NOT SUPPLYING POWER TO THE EMERGENCY LIGHTS.  MAINTENANCE REPLACED THE EMERGENCY POWER SUPPLY UNIT IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 33-51-01.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
