A de-icing truck collided with the side of the turbine engine of an Airbus A320 on a parking stand at Dublin Airport yesterday morning.
The plane was being de-iced at approximately 6.20am when the rig used to de-ice the plane reportedly malfunctioned and rolled into the engine.
The airline brought a reserve aircraft into service for the flight to Milan.
There were members of staff on the rig when it rolled into the plane, but it is not yet clear whether the plane had passengers on board.
The airlines are responsible for any de-icing operations at Dublin Airport.
