Thereafter the aircraft rolled momentarily back to a more neutral position. A few seconds later, while losing altitude, the second left wing down roll started. The left wing touched the ground and when the aircraft rolled back to a more neutral attitude both main landing gears touched the ground.

All gears broke off and the aircraft sled on the area next to the runway. Reportedly, during the impact or shortly thereafter all electrical powers were lost.
When the aircraft came to rest, the fire developed starting from the left wing root towards the fuselage. All passengers and crew were evacuated through the two right over wing emergency exits.
