It was reported that the engine caught fire and spread to the wing after touching down. There was 241POB, and zero casualties was reported
With video and photos available online, the right wings, flaps and leading edges were badly burnt. The fire was put out by the Airport Emergency Service and the passengers disembarked thought the stair and was transferred to the airport by bus.
The cause of fire is currently under investigation.
There are many discussions online to whether to evacuate the passengers using the left side doors. There are many factors to be considered, and ultimately is the safety of the passengers.
It may become chaotic quickly during the evacuation with the emergency response vehicles rushing to the scene and likely only the 1 & 5 Left doors are usable. Once evacuated, crews must ensure that the passengers move away from the flame and toward upwind. Therefore the crews and pilots must weight in these risk factors against keeping passengers aboard, with the wing on fire.
