“The crew followed all standard procedures and safely returned to MIA,” Atlas Air said in a statement, adding that it would conduct an inspection to determine the cause of the incident which occurred late on Thursday.

Unverified videos on social media platform X showed flames shooting out of the left wing of the aircraft while in flight.

Reuters could not immediately verify the authenticity of the videos.

The aircraft involved was a Boeing 747-8, Flightaware data showed. Boeing’s 747-8 is powered by four General Electric GEnx engines.

Miami-Dade Fire Rescue responded and no injuries were reported, the airport told Reuters.

Boeing, FAA and General Electric did not respond to Reuters requests for comment.

Boeing has been engulfed in a crisis since an Alaska Airlines MAX 9 airliner made an emergency landing after part of its fuselage broke off shortly after take-off from Portland, Oregon, on January 5.

The incident prompted the US Federal Aviation Administration (FAA) to temporarily ground 171 aircraft for safety checks.
