## Discrepancy

DURING TRANSIT CHECK, THE CENTER EMERGENCY LIGHTS ROWS 29 TO 33 TURNED OFF. MAINTENANCE PERSONNEL PERFORMED REVISION DETECTING THE BATTERY PACK FAILED; SO THE BATTERY PACK WAS REPLACED IAW AMM DMC-B787-A-33-51-07-02B-520A-A / 720A-A AND EMERGENCY LIGHT TEST WAS PERFORMED IAW AMM DMC B787-A-33-51-00-00B-320-A, TESTED CORRECT.
