Circumstances:
The pilot, sole on board, was engaged in a crop spraying mission over plantation located near Aksarino, Republic of Tatarstan, and the aircraft was carrying a load of 1,200 kilos of fertilizers. Shortly after takeoff, while climbing, the engine encountered technical problems. The pilot elected to make an emergency landing when the aircraft crash landed in a field and came to rest. The aircraft was damaged beyond repair and the pilot was uninjured.
Probable cause:
Most probably the accident with An-2 RA-54828 aircraft after its takeoff in order to perform crop dusting was caused by inadvertent engine cut-off due to water ingestion into fuel flow system. Most probably water ingestion into engine fuel flow system was due to violation of refueling procedure by the crew. The aircraft sustained significant damage during the emergency landing on slush soft surface.

Circumstances:
The history of occurrence was established based on the witnesses’ statements. On 31.07.2015, the aircraft AN-2 registered YR-PEG was positioned on a flight field in the vicinity of the farm in Stӑncuţa commune, Brăila County, being prepared in order to perform several aviochemical flights in Giurgeni area on the following day. In the morning of 01.08.2015, the pilot and the aeronautical technical staff from his team were informed by the beneficiary of aviochemical works that, because it was raining in Giurgeni area, they will perform some aviochemical flights in Stӑncuţa area, in the vicinity of the flight field. Consequently, the aircraft was prepared for the flight in the area as follows: 200 l of gasoline were defueled from the aircraft tanks, the engine was started and the operating parameters were checked according to the specific diagram. The aircraft was supplied with chemical substances for the aerial work and after only a few minutes, the engine was started again, in order to take-off. Onboard there were the pilot and an aeronautical technician (hereinafter referred to as passenger) who occupied the pilot's seat on the right. The take-off on the S-N direction was normal in the first part. The take-off run was short – approximately 100 m, in the witnesses’ opinion – under the conditions of a gusty wind from the E direction, whose speed was gradually increasing. During the initial climb, at a height of about 15-20 m, the aircraft began to lean to the left and descend slightly. During this turn in descent, bank angle continued to increase, the aircraft flying with the left wing at very low height above the aircrafts parked towards the northern end of the flight field. Considering the aircraft evolution and observing that the pilot was not acting for correction, the passenger onboard on the right-hand pilot seat, tried instinctively to turn the aircraft control yoke to the right. According to his statement, he failed to operate the control yoke, considering that this was in a blocking state of which nature he could not specify. With the engine still running in take-off mode, the aircraft continued to descend, and after passing the parked aircrafts, it hit the ground with the propeller and the left wing tip. The impact of the wing tip determined the aircraft to pivot to the left and make a hard contact with the ground. The engine stopped because of the shock. An early fire was extinguished by witnesses arrived at the accident site. Amid the destruction of the cockpit and fuselage, the pilot was thrown out of the aircraft suffering serious injuries. The passenger, who occupied the right-hand seat, managed (after recovering from the shock) to exit the aircraft wreckage. The pilot and passenger were transported to the hospital. Later on, the pilot died due to multiple traumatic injuries, and the passenger required a long hospitalization period due to the injuries suffered. The aircraft was totally destroyed. There was no other damage in the area.
Probable cause:
The probable causes of this accident are the following:
- Temporary incapacitation of the pilot,
- Use of flaps upon take-off in the conditions of deterioration/modification of weather conditions during take-off (wind direction and speed),
- Aircraft operation with incomplete crew.

Circumstances:
The single engine aircraft was engaged in a crop spraying mission on behalf of the Mikhail Farm located in the Tatsinsky District of the Rostov Region. The aircraft was carrying 400 kilos of fuel, 1,200 liters of pesticides, one pilot and one boy aged 13, the son of the farmer. Few minutes after takeoff, while approaching the area to be treated at a height of about 20-25 metres and at a speed of 130 km/h, the engine failed. The aircraft lost height, collided with power cables and crashed in a field, bursting into flames. The wreckage was found 2 km from the Mikhail farmhouse. The pilot escaped unhurt while the boy was injured. The aircraft was totally destroyed by a post crash fire.
Probable cause:
The reason for the accident with An-2 RA-84553 was performing a flight in a known defective aircraft, leading to engine failure and the need for in-flight forced landing, during which there was a collision with power lines, followed by a rough landing that led to the structural failure and fire. Investigation to determine the cause of the engine failure was not possible due to the failure to ensure the safety of the aircraft after the accident and the absence of operational and technical documentation. The adoption of the decision by the pilot to reject takeoff after detecting a loss engine power on the takeoff could have prevented the accident. The aircraft did not have a valid Certificate of Airworthiness and the time between overhauls had been exceeded on 10 April 2015.

Circumstances:
The crew was engaged in a crop spraying mission on rice paddy field located in Prototskiye (Krasnoarmeisk district of the Krasnodar region). Two minutes after takeoff, while flying at a height of about 50 metres, the engine lost power. The captain attempted an emergency landing when the aircraft nosed over and came to rest upside down, some 2 km east of Prototskiye. Those parts of the fuselage which were above the water were consumed by the erupting fire and both pilots escaped uninjured.
Probable cause:
The accident with An-2 RA-17890 aircraft was caused by its nosing-over during the emergency landing at the submerged rice bay. The emergency landing was due to the engine power loss in flight caused by the destruction of the can type combustor of the exhaust collector and burnout of the carburetor intake valve with the following high-temperature gases ingestion in the intake areas of the engine carburetor. The fatigue destruction of the can type combustor of the exhaust collector was caused along the main crack near the intake flex socket, it started from the surface of the damaged inlet port under the tube attachment pin towards the exhaust collector. By the moment of the main crack formation both inlet ports in left can type combustor under the tube attachment pin towards the exhaust collector had intolerable damage and size. During the last overhaul of the engine exhaust system of An-2 RA-17890 aircraft the left can type combustor had intolerable damage in its attaching lug to the exhaust collector which wasn't eliminated. The destruction of the inlet port valve was caused by the fusion of the boundaries of it material grains in conditions of acute temperature exposure induced by the destruction of the left can type combustor wall towards the main crack. Inadequate material (aluminum alloy D-16) of the valve specified by the drawing of aluminum allow AL-9T contributed to the valve destruction.

Circumstances:
The single engine aircraft departed Fertöszentmiklós Airport on a local spraying mission against mosquitos, carrying two pilots. Shortly after takeoff from runway 16, while in initial climb in a 15° flaps down configuration, the crew encountered problems with the engine that lost power and started to vibrate. While completing a left turn, the aircraft lost height, impacted ground and crashed in a cornfield. Both pilots escaped uninjured and the aircraft was damaged beyond repair.
Probable cause:
The accident was the result of a turn at low altitude and insufficient speed under the circumstances. The following contributing factors were identified:
- High ambient temperatures,
- The static load on the airplane at its maximum permissible level,
- Dust filter switched on unnecessarily,
- Unjustified use of carburetor heating,
- Increase propeller angle in the given flight position,
- Reducing engine power in the given flight position by taking back the throttle.
