Circumstances:
The crew was performing an illegal flight, maybe from Belarus, with an important load of Belarusian cigarettes on board. By night, while approaching an unused airfield, the single engine aircraft impacted ground and crashed in an open field. There was no fire. The aircraft was destroyed and both occupants were killed. The registration UR-54853 was announced to be illegal as it was already involved in an accident in Ukraine on 07FEB2013. The registration SP-AOD was still painted on the lower left wing, and the aircraft was operated since Summer 2013 illegally with the UR-54853 registration.

Circumstances:
The aircraft departed Surgut on September 12 on a special flight to Saranpaul and Arbyn, carrying two pilots and five employees of the Sosvapromgeologya Company. On September 18, the crew was supposed to fly back to Surgut but due to poor weather conditions, decided to fly to Nefteyugansk. About an hour and 10 minutes into the flight, while cruising at an altitude of 700 metres, the engine temperature increased to 305° C. and the oil temperature to 90° C. In the same time, the engine lost power. The crew decided to reduce his altitude and to attempt an emergency landing when the aircraft crash landed in a field located 48 km west of Nyagan. There was no fire. All seven occupants were injured and the aircraft was damaged beyond repair.
Probable cause:
Most probably the accident with An-2 RA-33017 aircraft was caused by usage of uncoordinated automative fuel not specified by valid aircraft maintenance engineering documentation with low octane grade, mechanical admixture (rusting) that resulted in cylinder-heads temperature increase beyond operating limits, engine power loss, unintentional flight altitude decrease and the need of an emergency landing on saturated terrain.
The contributing factors could be:
- Unsatisfactory management of storage, refiling procedures and fuel quality inspection at Arbyn Airfield,
- Incorrect PIC's decision to perform a flight after detection of deviation from standards in fuel quick drain (color, consistency, mechanical mixtures).

Crash of a PZL-Mielec AN-2R in Kamako

Circumstances:
Following an uneventful flight from Tshikapa, the pilot initiated the approach to Kamako Airfield in relative good conditions. On final, the wind component suddenly changed. The aircraft lost height and impacted ground 16 metres short of runway 12. Upon impact, the undercarriage were partially torn off and the aircraft slid before coming to rest 37 metres past the runway threshold. All six occupants, one pilot and five passengers, escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
It was determined that the loss of control that occurred on short final was the result of the combination of a human error and weather component. The pilot was surprised by the abrupt change in weather conditions on short final to Kamako runway 12. He elected to initiate a go-around procedure and increased engine power but unfortunately, low level windshear caused the aircraft to lose height and to struck the ground as its speed was insufficient. In consequence, the increase power was too low to allow the pilot to maintain the approach profile. The torsion of the blades confirmed that the engine was at full power for a go-around procedure at impact. The absence of a windsock at Kamako Airfield was considered as a contributing factor as this would help the pilot to recognize the wind component and to decide to land or to go-around in due time.

Circumstances:
Few minutes after takeoff from Vilyuisk Airport, on a schedule service (flight n° PI9977) to Kyubeinde-Ugulet, while cruising at an altitude of about 400 metres, the engine overheated and lost power while the oil pressure dropped. The crew decided to return to Vilyuisk when the engine failed shortly later. The captain attempted an emergency landing in a swampy area located 26 km northwest of Vilyuisk (at N63°54.584" E121°18.048"). The main wheels got stuck in soft ground, the engine was ripped off, and the aircraft came to rest, bursting into flames. Both pilots and all 9 passengers escaped uninjured and the aircraft was totally destroyed by fire.
Probable cause:
The accident with An-2Т RA-01419 aircraft was caused by emergency landing at the landing place in marsh area selected from air that resulted in main landing gear dipping in soft ground, dynamic pitch-down moment followed by engine ground impact and fuselage separation along engine mounting fitting, airframe structure and gear damage. Gasoline pipeline destruction during engine separation from aircraft frame and gasoline ingestion on the hot parts of power unit caused fire which almost completely destroyed the aircraft. Wrong PIC's actions who didn't turn off ignition and shut off fuel before aircraft landing could contribute to the fire. The emergency landing at the landing place selected from air was caused by oil temperature increase and pressure drop below specified by the aircraft FOM values in flight. It wasn't possible to determine the cause of temperature increase and oil pressure drop due to engine component substantial damage during fire.
