An Aer Lingus flight has returned to Dublin Airport after a "technical issue" onboard. Flight EI660 was en-route to Vienna when the incident happened.
A short time after 8:30am, the captain made the decision to return to Dublin.
The aircraft made a normal landing at 9:20am and emergency services were on stand-by.
Aer Lingus says as part of a normal precautionary procedure, the aircraft will undergo inspection.
It adds that passengers will be accommodated on an alternative aircraft and resume their journey.
It is the second unusual incident at Dublin Airport this morning, after two Ryanair planes made contact on the ground earlier.
Ryanair says the winglet of one aircraft appears to have scraped the tail fin of the other, while they were both taxiing to the runway.
It says both aircraft were under the instruction of Dublin Airport Air Traffic Control at the time.
In a statement, Ryanair adds: "Customers have been bussed back to the terminal and will board replacement aircraft to continue their journeys to Edinburgh and Zadar. Ryanair apologises sincerely to customers for any inconvenience caused."
Ran through T1 but as those two planes in the distance clipped each other, lots of delays @DublinAirport :( pic.twitter.com/k8yz4ALGze
