## Discrepancy

DURING C1 C CHECK, INSPECTION REPORTED THE OPERATIONAL TEST OF THE EMERGENCY LIGHTS FAILED WITH A FAULT MESSAGE OF "EPSU (13WL) AFT L/DEU B."  MAINTENANCE REMOVED AND REPLACED THE EPSU IN ACCORDANCE WITH THE REQUIREMENTS OF AMM 33-51-38-000-001 AND AMM 33-51-38-400-001.  UPON COMPLETION OF THE INSTALLATION, THE EPSU OPERATIONALLY CHECKED GOOD.
