An Aer Lingus Airbus A330-300, registration EI-FNG, was accelerating for takeoff from Dublin’s runway 28L on flight EI-123 from Dublin (Ireland) to Chicago O’Hare,IL (USA), when the crew rejected takeoff at low speed (about 35 knots over ground) due to a problem with the right hand engine (CF6), the aircraft briefly went off the runway centerline to the right but remained well within the runway
The crew then requested emergency services to inspect their right side; however, they were able to evacuate the runway and taxied off, regaining the runway center line.
After exiting the runway, the crew reported hearing a bang from the right side, but there was no indication of a fire, therefore they requested that emergency services inspect their right engine.
