• Takeoff from runway 06 was carried out (magnetic heading 58 degrees) at taxiway A11. The distance from the start of take-off to the point of collision with Snow blower ~ 1000 meters. The collision occurred at the intersection of the runways (the so-called "crossing").
• At the time of take-off as the following weather conditions: surface wind 120 ° - 3 m / s; at the beginning of runway 06: visibility - 350m, RVR¹ - 1000m; in the middle of the runway 06: visibility - 1000m, RVR - 2100m; slight drizzle, fog.
• At the time of the event the aircraft was under the control of start dispatcher of "tower". Control of the aircraft was carried out by trainee dispatcher under the supervision of a training controller.
• When issuing a dispatcher clearance to take off the runway was clear. The crew confirmed cleared for takeoff.
• After about 10 seconds after the confirmation by the crew of permission to take off the subsystem monitoring the airfield in the control point "tower" recorded movement of the snow thrower on the left edge of the runway 19 in a southerly direction towards the crossing.
• Neither a Request for permission for crossing the runway by the snowplow nor other communications were recorded on the tower audio recorder between the crew confirmed permission to take off and the accident.
• After ~ 14 seconds after the beginning of the aircraft take-off the crew observed an object, identified by them as "car crossing the road" (a phrase in French). The observation of this object did not cause concern and crew continued the take-off in the usual manner in compliance with standard operating procedures. ~ 14 seconds later the aircraft collided with a snowplow. The crew saw the snowplow just before the collision, after the normal command to lift the nose wheel.
• At the moment of collision with a snowplow the aircraft was in the air, the indicated airspeed was about 134 knots (~ 248 km / h). After the collision began to develop intensively right bank, which led to the collision of the aircraft with the ground.
• Failures in the operation of the aircraft systems and engines prior to the collision with a snowplow have not been identified.
