What was found
DURING POWER TRANSFER UPON ARRIVAL, THE FLIGHT ATTENDANT NOTICED THAT THE EMERGENCY PATHWAY LIGHTING FOR THE LAST TWELVE ROWS OF SEATS IN THE CABIN HAD FAILED. THIS WAS CONFIRMED DURING SHUTDOWN CHECK WHEN SECURING THE AIRCRAFT. MAINTENANCE REPLACED THE BATTERY PACK, THE BATTERIES, AND SOME BULBS TO GET THE LIGHTS TO RETURN TO AN OPERATIONAL CONDITION.
