## Discrepancy

AIRCRAFT WAS GROUNDED: DURING A SCHEDULED REPLACEMENT OF THE L1 DOOR SLIDE RAFT ASSEMBLY FAULT MESSAGES DISPLAYED DURING THE SYSTEM TEST OF THE EMERGENCY LIGHTING SYSTEM.

(AALA202604287506) IN ADDITION, MAINTENANCE ALSO REPLACED THE BATTERIES FOR EMERGENCY POWER SUPPLY UNITS 10WL (AALA202604286882) AND 13WL (AALA202604285119) PER AMM 33-51-38. A SATISFACTORY OPERATIONAL CHECK OF THE EMERGENCY LIGHTING SYSTEM WAS ACCOMPLISHED WITH NO FAULTS NOTED.
