## Discrepancy

ELECTRICAL ODOR & SMOKE FROM THE LT OVERWING EXIT AREA DURING CLIMBOUT OF EWR AND THE ODOR COULD BE SMELLED IN THE COCKPIT.  THE AIRCRAFT WAS DIVERTED TO PHL.  SMOKE STOPPED ON DESCENT & STARTED AGAIN ON APPROACH.  ACFT LANDED WITHOUT INCIDENT.  MAINTENANCE UNABLE TO DUPLICATE FAILURE DURING AN ENGINE RUN.  THE RT RECIRCULATION FAN (AIR DISTRIBUTION FAN) WAS REMOVED AND REPLACED ALONG WITH THE RT AIR FILTER.  THE ELECTRICAL ODOR CONTINUED SO THE LT AIR DISTRIBUTION FAN AND HEPA FILTER WERE ALSO REMOVED AND REPLACED.  BOTH AIR DISTRIBUTION FANS WERE TESTED AT THE VENDOR AND PASSED ALL PHASES OF FUNCTIONAL TESTING. NO PROBLEM COULD BE CONFIRMED WITH EITHER UNIT.
