The Airbus' right gear touched down 770m from the runway 11 threshold. The left gear touched down 9 seconds later, 1525m from the threshold. Only when the left gear touched the runway, automatic systems depending on oleo strut (shock absorber) compression unlocked the use of ground spoilers and engine thrust reversers. The wheel brakes, depending on wheel rotation being equivalent of circumfential speed of 72 knots began to operate after about 4 seconds. Seeing the approaching end of the runway and the obstacle behind it, the pilot steered the aircraft off the runway to the right. The aircraft left the runway at a speed of 72 knots and rolled 90m before it hit the embankment and an LLZ aerial with the left wing. A fire started in the left wing area and penetrated into the passenger cabin.
PROBABLE CAUSE: "Cause of the accident were incorrect decisions and actions of the flight crew taken in situation when the information about windshear at the approach to the runway was received. Windshear was produced by the front just passing the aerodrome; the front was accompanied by intensive variation of wind parameters as well as by heavy rain on the aerodrome itself.
Actions of the flight crew were also affected by design features of the aircraft which limited the feasibility of applying available braking systems as well as by insufficient information in the aircraft operations manual (AOM) relating to the increase of the landing distance."
