Circumstances:
The single engine airplane depart Ekimchan Airport at 0834LT on a cargo flight to Udskoye, carrying two pilots and a load of 1,199 kilos of various goods. Six minutes after takeoff, while climbing to an altitude of 1,600 metres, the crew noticed a strong smell of fuel in the cockpit and decided to return. During the descent, flames came out from the engine that started to rough and eventually stopped on short final. The airplane stalled, impacted a birch tree and crashed in a wooded area located 132 metres short of runway 06, bursting into flames. The copilot was killed and the captain was seriously injured. The aircraft was totally destroyed by a post crash fire.
Probable cause:
The crash of An-2 RA-02305 aircraft occurred during the forced landing. The necessity of the forced landing was caused by the engine stopping in flight due to the destruction of the cylinder head No.1 of the ASH62-IR engine No.K16509153. The destruction of cylinder head No. 1 is of fatigue nature and occurred due to exhaustion of fatigue life of the cylinder head material and reaching its limit state. Most likely, during the last repair of the engine the crack in the cylinder head was present, but was not through and was not revealed during the inspection. The most likely contributing factor to stopping the engine in flight was the impoverishment of the fuel-air mixture due to icing of the BAC filter mesh and the presence of a rubber plug on the filter flange of the corrector.

Circumstances:
The aircraft was engaged in a demonstration flight, taking part to an airshow at Chernoye Aerodrome, celebrating the 70th anniversary of the Antonov AN-2. The pilot-in-command completed a steep turn to the left to join the grassy runway. The airplane descended too low and impacted ground with its left wing and crashed 180 metres further, bursting into flames. The aircraft was totally destroyed and both occupants were killed.
Probable cause:
The most likely cause of the crash of the An-2 RA-35171 was the failure of the PIC to pilot the An-2 aircraft at high flight speeds (an increase in the time required for the aircraft to leave the bank due to the decrease in the angles of the aileron deflection due to the pulling of the cable line due to a significant increase in forces in the transverse of the control channel at speeds of 270-300 km/h), which did not allow the aircraft to arrest the descent when maneuvering with large angles of bank at an extremely low flight altitude.
The contributing factors were:
- Piloting the aircraft at modes beyond the limits set by the AFM of the An-2 aircraft;
- Maneuvering at an altitude less than that established for performing a demonstration flight over the aerodrome.

Circumstances:
The single engine aircraft departed Yeniseysk in the afternoon on a spraying mission over forest area, carrying two pilots. About 40 minutes into the flight, while completing a third pass at an altitude of about 400 metres, smoke spread in the cockpit. The crew decided to return to Yeniseysk when few minutes later, the engine lost power. Fuel leaked from the engine and spread over the windshield. The crew reduced his altitude to 50 metres and the speed to 85 km/h, preparing for an emergency landing. With the flaps down to 45°, the aircraft collided with trees and crashed in a wooded area located 75 km north of Yeniseysk. Both pilots were slightly injured and the aircraft was damaged beyond repair.
Probable cause:
Loss of engine power due to the failure of the cylinder n°5 caused by a faulty manufacturing.

The crew was engaged in a spraying mission over rice paddy fields in the region of Kiliya, Odessa. While completing the 18th sortie of the day, flying at a height of 50 metres and at a speed of 140-150 km/h, the engine failed. The crew attempted an emergency landing when the aircraft hit obstacles and trees and crashed. The captain escaped unhurt while the copilot was slightly injured. The aircraft was damaged beyond repair.
Probable cause:
Engine failure in flight due to fuel exhaustion.
The following contributing factors were identified:
- Poor flight preparation on part of the crew who failed to follow the pre-takeoff checklist,
- The fuel selector was in the wrong position,
- Poor organization on part of the operator, regarding implementation of procedures related to agricultural flghts.

Circumstances:
The single engine airplane was completing a positioning flight from Berdsk to Mansky where insecticides should be pulverized on wooded area. On board were a pilot, a mechanic and a passenger. Following a night in Berdsk, the airplane took off at 1201LT for the last leg to Mansky. En route, weather conditions deteriorated and the visibility was poor. Too low, the aircraft impacted trees and crashed in a wooded area located on the slope of Mt Abatova (747 metres high) located 40 km east of Krapivninsky. The airplane was destroyed by impact forces and a post crash fire. The wreckage was found the following day at an altitude of 541 metres. All three occupants were killed.
Crew:
R. Rodzhapov, pilot,
I. Valiullin, mechanic.
Passenger:
Yuri Pakhomov, maybe acting as a copilot on this flight, despite he was not licensed anymore.
Probable cause:
Controlled flight into terrain following the decision of the pilot to fly under VFR mode in IMC conditions in an uncontrolled area. Poor flight planning and flying without a copilot were considered as contributing factors.

Circumstances:
The airplane was engaged in a crop spraying mission, carrying a load of herbicides, one passenger and one pilot. In the early morning, while completing a seventh low pass, at a height of about 20-40 metres, the pilot initiated a left turn when the aircraft descended to the ground and crashed at a speed of 140 km/h in an open field, bursting into flames. The aircraft was destroyed by impact forces and a post crash fire and both occupants were killed.
Probable cause:
Fatal accident with Аn-2 RA-33462 agricultural aircraft occurred during aerial works on crop-dusting and was caused most probably by the piloting error consisting in unintentional descent when performing a turn for the next crop-dusting round which resulted in the aircraft controlled flight into terrain.
Most probably, the following factors contributed to the accident:
- The PIC not trained for crop-dusting flight without first officer,
- The PIC conducting the flight with a passenger on first-officer’s seat,
- The presence of alcohol in PIC's and the passenger's bodies,
- A possible transfer of the aircraft control from PIC to the passenger (former An-2 pilot) made by PIC,
- Violations of An-2 AFM and FAR-128 requirements on maintaining heights, bank angles during turns and flight speed while crop-dusting,
- Krasny Kut Civil Aviation Flight School management not controlling crop-dusting operations at the fields.
