An Atlas Air Boeing 747-8 cargo plane made an emergency landing in Miami shortly after departure after suffering an engine fire.
The plane with five crew members returned safely and no injuries were reported.
The Federal Aviation Administration (FAA) and National Transportation Safety Board are investigating. The FAA said a post-flight inspection showed a softball-size hole above the engine, while the NTSB said it “has opened an investigation and is collecting information to evaluate and determine scope of the investigation”.
“The crew followed all standard procedures and safely returned to [Miami International],” the air freight company said, adding that it would conduct an inspection to find the cause.
Boeing said it is supporting Atlas and “will support the NTSB investigation into this incident”.
The Atlas Boeing 747-8 is eight years old, according to the FAA and is powered by four General Electric GEnx engines.
GE Aerospace said is providing technical assistance to the FAA and the NTSB as they investigate.
The engine failure comes against the backdrop of two high-profile jetliner accidents this year.
On January 2, an Airbus A350 passenger plane operated by Japan Airlines collided with a Coast Guard aircraft in Tokyo, killing five crew members.
A few days later, a Boeing 737 Max 9 jet made an emergency landing after a cabin panel blowout, which prompted the FAA to temporarily ground 171 jets for safety checks.
The Atlas Air flight was headed for San Juan, Puerto Rico, from Miami International Airport late on Thursday.
The pilot made an emergency call to report an engine fire and asked to return to the airport, according to multichannel recordings of conversations between air traffic control and the plane.
“We have an engine fire,” one of the plane crew said, adding the fire occurred “on the climb out” of the airport.
