## Discrepancy

ON SERVICE CHECK, SOME CABIN EMERGENCY LIGHTS WERE FOUND TO BE INOPERATIVE. MAINTENANCE REPLACED THE EMERGENCY PATH LIGHTS AT 20DE, 23DE, AND 29DE. ALSO REPLACED BATTERIES IN EMERGENCY LIGHT BATTERY PACKS B5-100, B5-102, B5-103, B5-107, B5-27. EMERGENCY LIGHTS NOW TEST GOOD. (LP #4753454)
