С комментов avherald, похоже ребята из бек эир стараются во всю.
Part 1.
Dear All,
I'm the chief-pilot of Bek Air Company. It is a big tragedy to the aviation world, especially in Kazakhstan's history. To make your view more clear, let me provide you some more information about this accident. I see a lot of opinions about icing creation on the wing.
First of all, the weather conditions were: 1. Wind Direction = 140 degrees. 2. Wind Speed = 1 m/s. 3. Pressure: 1014 hPa. 4. Temperature = -12 degrees Celsius. 5. Visibility = 2100 meters. I want you to look at first to the pressure and temperature values that can show there was no ice condition during the Take-Off. Windshear can be also neglected due to the wind speed.

Part 2.
Secondly, the de-icing procedure was done on the stabilizer, which can mainly prove that the crew checked the wing and found it clear before the departure.
Thirdly, it was found that all anti-ice systems (engines, tail, wing) were switched on during the take-off. This was checked from the data taken from Operational FDR. It also shows that all control units were working and the pilot was controlling them.
Furthermore, Operational FDR also made measurements of wind direction and wind speed during the take-off. We could see that wind direction and the speeds were changing every 2-3 seconds with a high-value of change in direction (for example: from 135 to 0 degrees, from 2 to 20 knots).
Part 3.
These parameters are measured by the IRU system and have an error of 0,7 degrees and 1 knot respectively. The operational range of these measurements from -180 and +180 degrees, and 0 until 256 knots respectively. Therefore, we think that it was wake turbulence left from the previous aircraft. Everyone followed their rules and procedures (Bek Air, KazAirNavigation, Air Astana, Airport). But due to this situation happened in Almaty we need to think about changing intervals between the departures. At least to the Almaty airport which is located in the mountains.
I hope this information will really help. We're here to share our opinions and help to find what happened.
