Aviation authorities are investigating a case in which a Vietnam Airlines plane that departed from the central city of Da Nang en route to Hanoi made an emergency landing on Wednesday shortly after take-off.

Bound for Hanoi, flight VN7184, operated by the national flag carrier using an Airbus A321 plane, took off from Da Nang International Airport at 10:31 am on Wednesday.

As soon as a technical warning was detected after the take-off, the pilots decided to return to the Da Nang airport for investigation – a move aligning with air safety regulations.

Data on Flightradar24, a Swedish Internet-based service that shows real-time aircraft flight tracking information, indicated that the plane flew over Son Tra Peninsula and neighboring Quang Nam Province after taking off before making the emergency landing.

While some passengers aboard flight VN7184 shared that they had seen smoke billowing from an engine, a leader of the Central Airport Authority under the Civil Aviation Authority of Vietnam (CAAV) said the initial assessment showed that the problem may have involved a wind turbine.

The leader added that the incident was not serious and the flight crew did not need to seek emergency support upon landing.

He also assured that making an emergency landing after detecting a technical warning is a normal flight operation.

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

A technician at the Da Nang airport said that the smoke reported in the incident was likely a product of the incomplete combustion of fuel due to a lack of airflow, which sometimes happens on aircraft, regardless of airline or location.

The Airbus A321 involved in the incident is currently subjected to a technical check for the investigation into the cause.
