While descending towards Dubai the crew received ATIS reporting windshear on all runways.
The aircraft was configured for a landing with flaps at 30 degrees, the Vapp was computed to 152 KIAS (Vref 5 knots).
Descending through 35 feet AGL, at 159 KIAS, the captain initiated the flare, the autothrottle transitioned to IDLE and both thrust levers moved to the IDLE position.
Suddenly the aircraft hit the ground tail/belly first, at the same time the right hand engine caught fire, and the aircraft skidded to a halt, smoke filled the cabin, only at this time the passengers realised the seriousness of the situation. A ground observer reported EK-521 made a normal approach with the landing gear extended, touched down hard and went around, the gear was retracted, however the aircraft appeared to lack power and sank back onto the runway.
(Editorial note: The Aviation Herald noticed the lack of a significant detail in the narration of passengers mentioned above, there was no mention of sounds of engines spooling up).
About a minute later the commander transmitted a Mayday Call and advised they were evacuating.
Fire fighters arrived about one minute after the aircraft came to a stop and began to immediately apply foam.
