A chilling video posted on Russian social media purportedly shows the moment a passenger plane crash-landed at an airport in southern Russia, potentially killing dozens.

The flydubai flight from Dubai crashed on its second landing attempt in Rostov-on-Don early this morning, local time with about 62 people aboard.

A government source told Russian news outlet RT that all 55 passengers and sseven crew aboard were killed.

The confronting surveillance camera footage shot above a car park shows a bright flash across the sky followed by what appears to be an explosion on the ground.

"We are aware of an incident involving our flight FZ981 from Dubai to Rostov On Don," a statement from FlyDubai reads.

"We are investigating further details and will publish an update once more information is available."

Flight tracking website FlightRadar24 shows the aircraft aborting its initial attempt to land at the airport, then circling for almost two hours before the crash during its second landing attempt.

Flying in poor visibility conditions, the plane hit the ground between 50-100m away from the runway.

Most of the passengers aboard were Russians, and it is not known if any Australians were involved.
