The aircraft eventually took off at a speed of 205 km / h . The aircraft was flying at a speed of 210 km / h and a rate of climb of 1.4 m / s. At an altitude of 100–120 m, the flight captain gave the order to retract the landing flaps. The pilots reported the failure of the left engine to air traffic control and were instructed to fly a left turn at a height of 100 m and then to climb to 350 m.
