Narrative:
The Yak-40 operated on a domestic flight from Sverdlovsk (now named Yekaterinburg) to Kostanay and Dzhambul. The aircraft took off at 19:48:30 hours local time in darkness.
Throughout the flight, the engine thrust was insufficient. The aircraft climbed at a very shallow angle. At 19:50:25, at an altitude of just 100 m, the flight crew reported the failure of engine no.1. The flight crew turned left in an effort to return to the airport.
The aircraft struck trees on a hillside, 86 m above airfield elevation, and crashed.
It was determined that the crew failed to select engine anti-ice before takeoff. Additionally the maximum take-off weight of the aircraft was exceeded by 419 kg.
