Circumstances:
On a flight from Ust-Kamenogorsk to Alekseyevka when encountered below-minima weather conditions (low clouds and rain), entered clouds and deviated from the prescribed flight path by 6 km. The decision to return was taken too late and the aircraft crashed at a height of 970 metres into the steep slope of Mt Aina-Sulak (1,121 metres high) located 21 km southwest of Alekseyevka. Both pilots and all 10 passengers were killed.
Probable cause:
The crew exercised poor judgment and took the wrong decision while continuing the flight into adverse weather conditions and below-minima visibility.
