Circumstances:
The aircraft was performing a cargo flight from Kiev to Zaporozhie with an intermediate stop in Dniepropetrovsk, carrying a load of various goods for a total weight of 1,538 kilos, consisting of 566 kilos of mail, signal flares, brass twists and wires, and grinding wheels. On approach, at a height of 200-300 meters, the crew encountered marginal weather conditions, turbulences and strong winds when the left wing partially failed. The aircraft went out of control and crashed onto a hill located nine km short of runway. All four crew members were killed.
Probable cause:
It was determined that the aircraft encountered marginal weather conditions, winds up to 58 km/h and turbulences during the approach, causing the left wing to suffer a partial structural failure.

Circumstances:
The crew completed a mail/cargo flight from Dnipropetrovsk to Kryvyi Rih in the morning. At 1035LT, the crew departed Kryvyi Rih on the return empty leg to Dnipropetrovsk. While approaching the destination, the crew encountered thick fog with very limited visibility. The pilot reduced his altitude, probably to maintain a visual contact with the ground, when the airplane impacted with its right wing the metallic pylon of a high tension line (160,000 volts). The airplane lost height and crashed. The mechanic was injured and the pilot was killed.
Probable cause:
The accident was the consequence of a collision with a metallic pylon while the pilot was flying at an unsafe altitude in bad visibility. It was determined that the crew departed both Dnipropetrovsk and Kryvyi Rih Airport without any weather bulletin. Also, they were cleared for takeoff without such information. The people in charge to transmit weather bulletin prior to departure failed to do so.
