The Irish Aviation Authority has "strongly" advised passengers who own a Samsung Galaxy Note 7 to turn the device off and refrain from charging the phone on board aircraft.
In a Passenger Advisory Notice issued today, the IAA said passengers are also asked not to stow the Galaxy Note 7 in any checked-in baggage.
The advice applies to all Samsung Galaxy Note 7 devices, including recalled and replacement devices.
It comes as Samsung has scrapped its flagship smartphone, less than two months after its launch, after failing to resolve safety concerns.
Samsung announced the recall of 2.5 million Note 7s in early September following numerous reports of the phones catching fire and yesterday it finally pulled the plug on the €800 device in what could be one of the costliest product safety failures in tech history.
The decision to scrap the Note 7 came after fresh reports of fires in replacement devices prompted new warnings from regulators, phone carriers and airlines.
The company is offering to exchange the device for other products or refund customers.
Samsung's decision to pull the Note 7 off the shelves not only raises fresh doubts about the firm's quality control but could result in huge financial and reputational costs.
Analysts say a permanent end to Note 7 sales could cost Samsung up to $17bn and tarnish its other phone products in the minds of consumers and carriers.
