The crew attempted to takeoff from an airstrip located at Indra Lake bound for Verkhnyaya Salda with the MTOW exceeded by 170 kg and the center of gravity being out of the envelope (too far aft).

- The total weight of the aircraft was in excess of 170 kg to the MTOW,
- The CofG was too far aft and out of the envelope,
- The captain and the second pilot (a passenger) were intoxicated.
