A replacement model of the Samsung Note7 smartphone started emitting smoke inside an aircraft in the United States on Wednesday, triggering an evacuation drill. All passengers and crew members were taken off the Southwest Airlines flight to Baltimore from Louisville, Kentucky.

The owner of the phone, Indiana passenger Brian Green, said he had exchanged his phone on September 21. His wife Sarah told Reuters that Green had replaced the original phone after getting a text message from Samsung. According to The Verge, Green’s new phone came in a packet that had a label on it indicating it was a replaced model.

The incident prompted fresh investigations by the Consumer Product Safety Commission and the Federal Aviation Administration. The FAA confirmed that a Samsung phone caused the smoke and added that an investigation was underway. Samsung Electronics Company, however, said it was yet to ascertain the cause. “Until we are able to retrieve the device, we cannot confirm that this incident involves the new Note 7,” said the South Korean company’s statement.

The incident comes after the world's largest smartphone maker announced a global recall of at least 2.5 million Note7 smartphones because of faulty batteries. Last month, the Consumer Product Safety Commission of the United States found that there have been 92 cases of battery explosions in such models in the country, besides 26 instances of burns and 55 reports of property damage. Last week, Samsung said it had replaced around 60% of the phones in South Korea and the United States, reported The Guardian.

Australia was the first country to ban the use of the phone inside an aircraft. Japan has also issued a similar advisory, followed by the US. In India, the Director General of Civil Aviation BS Bhullar had also asked people not to put the phone in checked baggage. However, the model has not been banned from being used inside any aircraft.
