A Vietnam Airlines flight from Da Nang to Hanoi was forced to make an emergency landing not long after take-off on Wednesday morning after smoke was seen billowing from an engine.

The Airbus A321 with 111 passengers onboard retuned to Da Nang Airport after the problem was reported.

All passengers were transferred to other flights later the same day.

Technicians are inspecting the plane to determine the cause of the problem.

Bui Van Thanh, director of the Central Region Airports Authority under the Civil Aviation Authority of Vietnam, told the Vietnam News Agency that the incident was not serious and the flight crew didn’t need to seek emergency support upon landing.

The case has been reported to the CAAV, Thanh said, and further developments, if any, would be made public when available.

According to local media, the smoke was not because of a fire in the engine but rather a product of the incomplete combustion of fuel due to a lack of airflow.
