## Discrepancy

FLIGHT WIG046A DEPARTED MHT-MVY NORMALLY.  WHILE CLIMBING THRU 4500 FEET THE PILOT NOTED ELECTRICAL FUMES.  THE PILOT DID NOT NOTICE SMOKE BUT ELECTED TO RETURN TO MHT AS A PRECAUTION AND LANDED WITHOUT INCIDENT.  MAINTENANCE EVALUATED THE AIRCRAFT AND DETERMINED THAT THE ACU HAD FAILED.  THE PART WAS REPLACED AND OPERATIONALLY TESTED GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
