The single engine airplane departed Salekhard Airport at 1903LT on a cargo flight to Mys Kamennyy, carrying a load of 41 alcohol bottles for a total weight of 800 kilos. During initial climb, while flying by a polar night at a speed of 230 km/h, the airplane went out of control and crashed in a snow covered tundra located about 8 km north of Salekhard Airport. The airplane was destroyed and both occupants were killed.

Probable cause:

The crew lost control of the airplane during a night flight after suffering a spatial disorientation caused by the failure of both AGK-47B artificial horizon and GPK-48 gyro compass. It was reported these instruments already failed before the accident without the cause having been established.

Circumstances:

The aircraft was performing a cargo flight from Salekhard to Tarko-Sale, carrying six crew members and a load of 11 tons of cement. Rotation was completed after a course of 1,250 meters. Immediately following takeoff, the airplane entered a steep nose-high attitude (angle of attack of 20°) then banked right and crashed one minute later in a field located 1,800 meters past the runway end. A crew member was rescued while five other occupants were killed.

Probable cause:

Failure of the crew to prepare the flight properly and to follow the pre-takeoff checklist. Takeoff maneuver was completed with the flaps still retracted, causing the airplane to stalled after rotation.

Circumstances:

The crew was involved in a military cargo flight and the aircraft was carrying a load of metallic pipes intended for a pipeline construction. During the takeoff roll, the pilot-in-command encountered an unexpected situation and decided to abort. Unable to stop within the remaining distance, the airplane overran and came to rest in a ditch located 50 meters past the runway end. All six crew members were slightly injured while the aircraft was damaged beyond repair.

Probable cause:

It was determined that prior to takeoff at Tyumen Airport, the crew was instructed to hold for few minutes as an Antonov AN-2 was attempting to land. During this period of time, the crew activated the parking brake and then failed to release it when he was cleared for takeoff. During the takeoff roll, the aircraft was unable to rotate because the parking brake was not released and its speed was insufficient, two factors that were not noticed by the crew in due time.

Circumstances:

The aircraft left Sverdlovsk Airport bound for Petropavl with four passengers, a crew of five, 869 kilos of mail and 496 kilos of various goods. While cruising by night, the crew encountered higher winds than predicted and due to the lack of visibility, lost their orientation and were unable to locate the airport of Petropavl. The captain decided to divert to Kurgan Airport but was unable to contact ground due to communication problems. He then decided to return to Svedlovsk but as the fuel reserves were too low, he eventually decided to continue to Petropavl that was closed due to poor weather conditions. While cruising in snow falls about 215 km from Petropavl Airport, both engines failed due fuel exhaustion. The crew attempted an emergency landing in a snow covered field when the airplane crashed 250 meters from the Omsk-Tyumen railroad. Two passengers were seriously injured while all seven other occupants were killed.

Probable cause:

The accident was the consequence of a loss of orientation by the crew in flight due to the combination of the following factors:
- Lack of discipline on part of the crew,
- Poor flight preparation with the result of insufficient fuel reserve for the entire duration of flight,
- Errors in flight in the navigation calculation. More than two hours of flight were not recorded in the navigator's logbook,
- Failure to use the flight direction finder,
- Poor weather conditions at night with high winds and snow falls,
- Unsatisfactory flight management from RDS Koltsovo and ADS Kurgan.
The following findings were considered as contributing:
- Unjustified weather forecast in the direction of the wind, issued by AMSG Koltsovo,
- Unstable work of the radio compass,
- Insufficient fuel for the operation,
- Unstable work of the communication equipment,
- Low qualification of the communications operators.
