"Approximately three minutes after power up, the aircraft began to move forward. The technician in the left seat perceived the motion and informed the Airbus technician in the right seat. The latter acted on the brake pedals and then released the parking brake. The DFDR (digital flight data recorder) then indicates a partial release of the brake pedal command. Since the aircraft continued to move forward, he tried to modify its trajectory by using the nose wheel steering. The nose wheel gear quickly skidded sideways as the aircraft accelerated.
The aircraft struck the slope of the anti-blast wall. The forward fuselage broke and fell down on the other side of the wall.
There were thirteen seconds between the start of aircraft movement and the collision with the wall."[/quote:21l1ezst]
