On october 13, a UTair boeing 737-500 registrated as VQ-BJP, doing a flight UT588 from Krasnodar to Moscow, stalled while entering the glideslope near Vnukovo international airport.
As the Rosaviatsia says in their document, at the time of the incident there was 111 passengers along with 5 crew members onboard. Plane’s landing weight was 44,9 tons. Pilots finally exited stall at about 350 meters above the ground. At the time of the incident, there was a little 2 mps (meters per second) with gusts up to 5mps, visibility varied between 2 and 2.7km, there was also a haze.
According to the flight recorder, the autopilot was turned on before the glide slope entrance point (the final descend path to the runaway). At this time, the pilots started releasing flaps down to 30 degrees, and while the flaps were releasing, the autopilot was turned off, except for the traction automat (speed autopilot). While flaps were releasing, the aircraft began to slow down, and the traction automat increased the engine power to 95%. The position of the engines under the fuselage on this type of aircraft, along with high trust to weight ratio led to nose rising up, altitude rising up, and airspeed falling. The pilots tried to fix the situation and lower the nose by pulling the yoke away from them and moving the trust levers down in order to lower the engine thrust, however the traction automation was still on. As a result, the nose of the plane went so high, that the pitch was 45 degrees (!), and the airspeed fell below 100 knots (while minimum airspeed on this plane with this configuration is 114 knots), and the airliner started to roll left and right to 95 degrees. Pilots were still trying to lower the nose by pulling the yoke away from them. At an altitude of about 750 meters above ground, the aircraft first lowered his nose to the horizon, but then it continued going down to the ground, and soon the airplane started to drop sharply. Then finally, at the altitude of 350 meters above the ground, plane finally exited this difficult spatial position. After that, the plane continued to climb, and then landed safely at Vnukovo. However, UTair denies the fact of accident with any of their planes on the Krasnodar-Moscow route on october 13. In the end of the document confirming the fact of accident, Rosaviatsiya recommendations on how to prevent this type of accidents in the future. In particular, paying more attention to the training of the flight crew for the withdrawal of the aircraft from a complex spatial situation.
It is truly scary, as on the approach to runaway 24, planes turn closely or even above highly populated yasenevo area.
