Circumstances:
During a crop spraying flight from Zaupory (Batetski district of the Novgorod region) for the sovkhoz (state farm) of "Peredolski", the engine lost power while the aircraft was flying at low height. The airplane lost height then collided with the roof of a horse stable before coming to rest on the banks of the river Luga located near Rechka. Both pilots were killed.
Probable cause:
The engine failure was caused by soot deposits in the inlet valves.

Circumstances:
The airplane was engaged in a weather survey mission over the Baltic sea and was carrying two passengers and a crew of six. While returning to his base at Kaliningrad-Khrabrovo Airport, the crew failed to set the altimeter properly, causing the aircraft to approach the land at an insufficient altitude. In low clouds, the pilot-in-command did not realize his altitude was too low when the airplane struck trees, lost height and crashed in flames 200 meters further onto a school. The airplane was totally destroyed by impact forces and a post crash fire as well as the school building. All eight occupants on board the aircraft were killed as well as 27 people on the ground, 23 children and three adults. Two other children were seriously injured.
Probable cause:
Wrong altimeter setting caused the aircraft to fly at an insufficient altitude. Lack of visibility due to low clouds and poor ATC assistance was considered as contributing factors.

Circumstances:
The crew was involved in a crop-spraying mission for the kolkhoz (collective farm) of Karl Marx located in Devyaternya (Argyz district of Tatarstan). He decided to takeoff from an area facing a forest and after liftoff, while climbing, the airplane struck birch trees (24 meters high) and crashed in flames 1,162 meters from the departure point. The aircraft was destroyed by a post crash fire and both pilots were killed. Weather conditions were considered as good at the time of the accident.
Probable cause:
It was determined that the crew took the wrong decision in taking off facing the wooded area. The presence of orographic waves was considered as a contributing factor.

Circumstances:
The three engine aircraft departed Irkutsk-Magan Airport at 2229LT bound to the north, cruising at an altitude of 6,000 meters. Weather conditions en route were good. While descending to Bratsk Airport, the crew was informed about the last weather bulletin with no precipitations and a visibility of 50 km. However, during the night approach, weather conditions deteriorated with heavy mixed rain/snow showers and a visibility limited to one km. On short final, the airplane lost height then struck trees and crashed in flames 225 meters further, about 1,250 meters short of runway threshold. The airplane was destroyed by impact forces and a post crash fire and all 18 occupants were killed.
Probable cause:
It was determined that ATC in Bratsk transmitted to the crew a wrong weather bulletin that was referring to weather conditions at 2315LT. Unfortunately, ATC attempted without success to obtain an updated weather briefing and transmitted inaccurate information to the crew. On final, heavy snow/rain showers associated with downdraft and unfavorable winds caused the aircraft to lose height and to crash. The assumption that the crew inadvertently selected the reverse thrust during final approach was not ruled out.

Out of control, the airplane crashed upside down into a water filled ravine located 258 meters further. The wreckage was found 500 meters southwest of Vyezdnoye. Both pilots were killed.
Probable cause:
The crew failed to follow the minimum safe altitude for such operation.

They were returning to Nizhneyansk after they completed investigations following an incident that involved another AN-2 registered CCCP-13704 few days ago. After takeoff, while climbing to a height of 60 meters with flaps up, the airplane banked left to an angle of 45° then stalled and struck the ground. Out of control, it crashed in a snow covered field and came to rest. A passenger was killed while three other occupants were seriously injured. The aircraft was destroyed. At the time of the accident, wind was gusting from 110° at 54 km/h with an OAT of -15° C.
Probable cause:
It was determined that the crew forgot to position the flaps down for takeoff.
