## Discrepancy

(CAN) ELECTRICAL ODOR IN REAR GALLEY.  ENGINEERS DISCOVERED THAT AN OVERHEAD CABIN SIDE WALL BULB, 21B WAS BEGINNING TO SPARK AND SMOULDER, PRODUCING A PLASTIC BURNING SMELL, SIMILAR TO THE SAME ODOR EXPERIENCED BEFORE.  BULB REMOVED AND SURROUNDING AREA EXAMINED. CBS TO SIDE WALL PULLED ISOLATING THE ROW OF LIGHTS.  SIDEWALL LAMP HOLDER REPLACED.
