Plane Fire at Denver Airport Forces Passengers to Evacuate Onto Wing

An American Airlines plane that was diverted to Denver International Airport on Thursday evening after experiencing “engine vibrations” caught fire while taxiing to a gate, prompting the evacuation of dozens of passengers, according to the Federal Aviation Administration and videos posted to social media.

The flight, a Boeing 737-800 with 172 passengers and six crew members, was traveling from Colorado Springs to Dallas but was diverted to the Denver airport, the airline said. Some of the passengers were evacuated from the aircraft using slides, the F.A.A. said.

“After landing safely and taxiing to the gate at Denver International Airport, American Airlines Flight 1006 experienced an engine-related issue,” the airline said, adding that the passengers and crew members had left the plane and had been taken to the terminal.

Videos posted to social media showed passengers standing on the plane’s wing and climbing down a portable staircase to leave the plane. Light gray smoke filled the air. From other angles, black smoke poured out of the aircraft and orange flames could be seen at the base of the aircraft.

A video taken by Mike Insalata, a Denver resident, showed a large fire under the plane’s left engine. It was not immediately clear if anyone had been injured.

This is a developing story.
