Tyumen | Bureau of Aircraft Accidents Archives

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:

On final approach to Khanty-Mansiysk Airport, the crew failed to realize his altitude was insufficient when the airplane struck a snow covered field. It bounced then crashed in flames short of runway threshold. Four crew members were seriously injured while 43 other occupants were killed. The aircraft was destroyed.

Probable cause:

Possible wrong approach configuration and errors in the piloting techniques, expressed in an inaccurate determination of the airplane's altitude during the final stage of the approach.

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.

Circumstances:

The airplane departed Tyumen Airport at 0805LT on a special flight to Sverdlovsk, carrying three crew members and seven passengers on their way to a political party committee meeting. A little more than an hour into the flight, while cruising at an altitude of 100 metres in good weather conditions, the left engine failed. The pilot lost control of the airplane that rolled to the left then entered a dive and crashed 1,5 km from the village of Chernokorova, bursting into flames. The airplane was totally destroyed and all 10 occupants were killed.

Probable cause:

Loss of control in flight following the failure of the left engine for undetermined reasons.
The following contributing factors were identified:
- The pilot took the decision to continue the flight at an unsafe altitude of 100 metres above ground,
- The crew failed to proceed with a pre takeoff check of the airplane,
- No technical check of the airplane was made since last October 4,
- The total weight of the aircraft was 160 kg above MTOW.
