Out of control, the airplane crashed in flames 300 meters further. Two crew members were killed while a third occupant was injured.
Probable cause:
The crew decided to continue the approach in foggy conditions without any visual contact with the ground. At the time of the accident, Kermanshah Airport was not equipped with a control tower.

Circumstances:
While on a positioning flight from Osinovka-Andreyevka to Almaty for crop-spraying operations for the sovkhoz (state farm) 'Andreyevski' with 2 mechanics and 2 local guides on board, the captain decided not to circumvent the Chubundy (Shybyndy) mountain ridge but to make a straight-in flight. Few minutes later, he encountered below-minima weather conditions and decided to return to Andreyevka but this was too late. Shortly later, while completing a turn in clouds at an altitude of 1,200 meters, the single engine airplane collided with the summit of a ridge located about 15 km northeast of Andreyevka Airport and crashed. Injured, the copilot walked down the mountain to find help. The captain was killed while all five other occupants were injured.
Probable cause:
Controlled flight into terrain caused by wrong in-flight decisions on part of the captain.

- Improper emergency procedures,
- Unwanted thrust reversal,
- Continued operations of left engine at climb power after unwanted in-flight deployment of the left engine thrust reverser.
