## Discrepancy

FLIGHT 796, PHL-TLV - SHORTLY AFTER DEPARTURE THE FLIGHT CREW WAS ADVISED OF AN ODOR IN THE CABIN WHICH RESEMBLED A "HOT, ELECTRICAL" SMELL.  THE ODOR DID NOT DISSIPATE, SO THE FLIGHT CREW CHOSE TO RETURN TO PHL AS A PRECAUTION.  AN EMERGENCY WAS DECLARED AND THE FLIGHT LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE NR 1 ENGINE.  INSPECTED THE LEFT HAND PACK AND REPLACED THE PRIMARY AND SECONDARY HEAT EXCHANGERS, ACM, AND PLENUM CHAMBER DUE TO CONTAMINATION.
