An overheating, smoking Samsung smartphone has forced the evacuation of a Southwest Airlines jet that was preparing to take off from Louisville airport.
The incident raised fresh trouble for Samsung, which saw its new Galaxy Note 7 device recalled last month because of overheating batteries.
Samsung, Southwest and federal aviation-safety officials declined to say what model of Samsung phone was involved, saying they were still investigating.
But an Indiana woman, Sarah Green, told The Courier-Journal of Louisville that it was her husband's Galaxy Note 7 that made popping noises and started to smoke after he powered it down while the plane sat at the gate.
Green told the newspaper that her husband, Brian, received the Galaxy Note 7 about two weeks ago as a replacement for his recalled phone. He called her from someone else's phone to tell her what happened.
Last month Samsung agreed to recall the Galaxy Note 7 after receiving 92 reports of batteries overheating in the US, including 26 reports of burns and 55 cases of property damage.
The Federal Aviation Administration took the unusual step of warning passengers not to use or charge the devices while on board and not to stow them in checked luggage.
Flight attendants on many airlines added a warning about the Samsung device to their pre-flight safety demonstrations.
However, the FAA's advisory to airlines did not apply to replacement Galaxy Note 7s. Those phones have a green battery icon.
Samsung Electronics said in a statement that it could not confirm that the latest incident involved a new Note 7. Samsung said it is working with authorities to recover the device and confirm the cause of overheating.
Wednesday's mishap occurred while the Southwest plane with 75 passengers and crew members prepared to fly from Louisville to Baltimore. Fire Capt. Sal Melendez said the device overheated during the crew's safety demonstration.
Southwest Airlines spokesman Brad Hawkins said a passenger reported smoke coming from a Samsung device and that everyone got off the plane through the main cabin door.
No one was injured in the evacuation, but the plane's carpet suffered minor damage where the phone was dropped, fire officials said.
