The crew did not release the interceptors, and the plane landed with overload.
Rosavitsiya conducted a partial analysis of the actions of the crew and the work of the Aeroflot Sukhoi Superjet 100 (SSJ-100) aircraft, which burned down after landing at Sheremetyevo. This was reported by RIA “News” with reference to a document from the Ministry.
According to the document:
- At the time of landing, the mass of the SSJ-100 was about 42.6 thousand kilograms, which is 1.6 thousand kilograms more than the maximum permissible landing weight;
- Landing was carried out without significant deviations at a speed of 155-160 knots (287-296 kilometers per hour). Rosaviatsia clarified that according to the flight manual, the approach speed for the conditions was 155 knots;
- The crew of the SSJ-100, contrary to the instructions, did not release thespoilers (brake covers). Automatic release of brake flaps in “direct mode” or “minimum fcs mode” is not provided, clarified in the department;
- During the landing approach, the commander of the airliner “with maximum effort” tried several times to divert the vessel up and down. This led to alternating changes in the pitch angle (from plus six degrees to minus two);
- The SSJ-100 fire alarm went off 4 seconds before the plane stopped and the fire extinguishing system after 20 seconds.
On the evening of May 5, the Aeroflot plane, which was traveling from Moscow to Murmansk, caught fire during an emergency landing at Sheremetyevo. On board the ship were 78 people, including five crew members. Because of the fire, 41 people died, including one child and a flight attendant.
On May 15, a source close to the investigation told Kommersant that lightning struck the SSJ-100, but the Aeroflot pilots themselves made a critical situation. He believes that the crew began to “press” the board to the ground – this maneuver and became the cause of the disaster.
