## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO DFW DUE TO THE FLIGHT CREW REPORTING THAT DURING CLIMB OUT AN ECAM MESSAGE FOR ENGINE 1 LOW OIL PRESSURE DISPLAYED. THE FLIGHT CREW REPORTED THAT THE OIL PRESSURE INDICATION INITIALLY FLUCTUATED AND THEN DISAPPEARED WITH AMBER XX. INDICATIONS BUT RETURNED AFTER APPROXIMATELY 5 MINUTES FLUCTUATING MOMENTARY AND THEN FEATURED TO NORMAL PARAMETERS. THE AIRCRAFT LANDED SAFELY AT DFW AND TAXIED TO THE GATE UNDER ITS OWN POWER. MAINTENANCE REPLACED THE #1 ENGINE INTERFACE UNIT PER AMM 73-25-34 AND ACCOMPLISHED A SATISFACTORY OPERATIONAL CHECK WITH NO OIL PRESSURE FUCTUATIONS NOTED.
