Circumstances:
The crew was performing a survey flight while in a fire fighting program. In flight, the engine failed and the crew elected to make an emergency landing. The aircraft stalled and crashed in the Varnavka River. Both pilots and the passenger were injured while the aircraft sank and was damaged beyond repair.
Probable cause:
The accident was the result of a forced landing on the water surface due to unstable operation of the engine after a loss of power which was caused by the re-enrichment of the fuel-air mixture because of jamming of the needle valve of the left float chamber of the carburetor. The most probable reason for jamming of the needle valve of the left float chamber is its clogging by foreign particles that resulted from failure to comply with section 2.02.01.20 of the rules of maintenance of the AN-2 while performing 100-hour maintenance works due to lack of RTO requirements for mandatory compliance.

Circumstances:
The crew was on a positioning flight for a crop-spraying mission in North Kazakhstan when he lost his orientation between the villages of Taiynsha and Sorochinskiy. He landed on a small field near the village of Sarybulak to establish his position. After takeoff with a slight tail wind, at a height of 15 metres, the pilot-in-command initiated a left turn when the left lower wing struck a tree. The aircraft stalled and crashed, bursting into flames. Both pilots were killed while the engineer was seriously injured. The aircraft was totally destroyed by a post crash fire.
Probable cause:
The following findings were identified:
- Takeoff from a limited area,
- Failure to take into account obstacles by the crew during takeoff,
- Incorrect selection of the take-off site;
- High outside air temperature and tailwind component.

Circumstances:
Shortly after take off from an open field located in Goryachy Klyuch, Krasnodar krai, while at a height of about 15 metres, the single engine aircraft stalled and crashed on a river shore. Both pilots were injured and the aircraft was damaged beyond repair. The crew was supposed to treat a wooded area with chemical products and the aircraft was carrying about 700 liters of this product at the time of the accident.
Probable cause:
The accident of airplane AN-2 RA-40373 was the result of the nose striking the ground during the execution of a forced landing due to shutdown of the ASz-62IR engine while in the process of taking off, most likely due to ingress of water into the carburetor from the fuel system of the aircraft, which led to the shutdown of the engine.
The cause of the accident was a combination of the following factors:
- Failure to comply with guidelines in part: checking facility for storing and dispensing aviation fuels and lubricants, monitoring and verification of the fuel sludge discharge after refueling for the lack of water and solids;
- Execution of a forced landing straight ahead outside the landing area on difficult terrain, covered with forests, a rugged ravine and a creek.

Circumstances:
The Antonov 2 aircraft was assigned to spray birds at the white Nile Scheme. The aircraft arrived at Um-galala airstrip 5 days before the accident date and carried out seven spraying flight in the previous five days. The spraying of birds start daily about 18:30 local time and took about 50 minutes flight. According to the scheduled operation the aircraft started its flight ten minutes before Sun set to fly to the assigned bird location for spraying chemicals.On the day of the accident the airstrip lights were positioned by the captain himself at the edges of the airstrip. He put seven lamps at the left side and three lamps at the right side of the airstrip. The red lamp which should have been placed at the beginning of the airstrip was not placed that day due to a flat battery. At about 15:45 UTC the aircraft took-off for spraying birds. That night was dark and there was no moon light. After take-off the technician switched on all lamps except the red one waiting for aircraft arrival. Fifty minutes after take-off the aircraft was seen approaching the airstrip. The aircraft came flying over the strip at a height of about 25 meters and made a left turn. The aircraft then made another approach and came over the left row of lamps at a height of about 10 meters, as stated by the technician, and made a sharp left turn. At that instant the aircraft went down and crashed east of the airstrip. A fire erupted. The pilot died of his injuries. Although the airplane was formally registered ST-AUS in July 2009, the airplane still carried its previous Polish registration mark SP-WMH.
Probable cause:
The captain, as he was not rated for instrument flying, was disoriented by the absence of the red lamp which was used to indicate the beginning and center line of the airstrip in addition to remains of birds on windscreen which decreased the pilot vision. The presence of some people from the village within the East side of airstrip causing illusion of vision to the pilot was considered a contributory factor to this accident.
