Circumstances:
On a night approach to Novosibirsk-Severny Airport, the crew encountered bad visibility due to fog. On final, the aircraft was 300 meters to the left of the glide and the crew failed to have a visual contact with the runway and ground. In such conditions, the captain decided to abandon the approach and made a go around. Few minutes later, the crew started a second approach with a horizontal visibility of 100 meters. Without any visual contact with the ground or the runway, the pilot-in-command continued the approach, passed below the decision height when the airplane hit trees and crashed in a wooded area located few km short of runway. The aircraft was totally destroyed upon impact but there was no fire. All 29 occupants were killed.
Probable cause:
It was determined that the visibility was below minima at the time of the accident. Because the crew failed to establish any visual contact with the ground and did not have the runway in sight, it would be necessary to divert to the alternate airport for a safe landing. Continuing the approach without any visual contact with the ground and passing below the decision height, the crew engaged the aircraft in a controlled flight into terrain.

Circumstances:
The aircraft left Krasnoyarsk Airport at 1755LT bound for Novosibirsk with an assigned altitude of 2,100 meters. At 1840LT, a second Lisunov LI-2T registered CCCP-A4031 left Novosibirsk Airport bound for Kemerovo with a crew of seven who were involved in an aerial photography mission. While approaching Kemerovo, the captain of the first LI-2 modified his route and flight level without prior permission and passed north of Kemerovo. In excellent weather conditions, while cruising at an altitude of 1,800 meters to a heading of 270° and facing the sun, the first LI-2 was hit on its right wing and right engine by the second LI-2 that was flying from the opposite. Following the collision, both aircraft dove into the ground and crashed in a wooded area located 16,5 km west of Barzas. Debris were found on a greater distance than 600 meters and all 27 occupants on both aircraft were killed.
Probable cause:
It was determined that the pilot of the LI-2 registered CCCP-L4534 deliberately decided to modify his flight path and flight level without prior permission from ATC. Doing so, he flew into the flight path of the second aircraft that was flying to a heading of 90°. It was reported that the pilot at fault had been degraded to the co-pilot position in July 1952 due to lack of discipline and loss of direction. He had returned to his captain position last February despite serious shortcomings in piloting techniques. The low position of the sun was considered as a contributory factor.

Circumstances:
The airplane left Yeniseysk Airport at 1655LT bound for Krasnoyarsk. Thirty minutes later, while cruising at an altitude of 1,800 meters by night and in good weather conditions, the crew encountered technical problems with the left propeller that was over speeding. For unknown reason, the crew was unable to feather the propeller and took the decision to return to Yeniseysk. Due to drag, the aircraft lost height and thirty minutes later, at a speed of 130 km/h, it hit tree tops and crashed in a wooded area located 25 km south of Yeniseysk Airport. Three passengers were killed while 16 other occupants were injured. The aircraft was destroyed.
Probable cause:
Failure of the pressure switch on the left-hand drive regulator in flight, which caused the propeller to overspeed. A contributory factor was the crew who failed to set the nominal mode of operation on the right engine immediately after the start of the descent, using full power on the right engine with delay, which caused the aircraft to lose altitude rapidly. Despite good visibility due to moonlight, the crew failed to attempt an emergency belly landing in a suitable terrain.

Circumstances:
The aircraft was completing a flight from Khabarovsk to Tashkent with intermediate stops in Krasnoyarsk and Novosibirsk, carrying a crew of six and one passenger, a Soviet Army Officer. The airplane left Krasnoyarsk Airport at 1822LT bound for Novosibirsk. En route, the crew encountered poor weather conditions with low clouds and rain falls. While cruising at an altitude of 1,500 meters in the clouds, the crew encountered icing conditions and obtained the permission to descend to 900 meters. As the aircraft failed to arrive in Novosibirsk, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the seven occupants was found. The wreckage was found 15 years later, in 1967, on the northwestern slope of Mt Kuznetsky Alatau (1,037 meters high) located in the region of Belogorsk. According to investigations, it appears the aircraft hit tree tops, flew about 70 meters and crashed in flames in a wooded area at an altitude of 710 meters. The airplane disintegrated on impact and was consumed by a post crash fire. All seven occupants were killed.
Probable cause:
It is believed that the accident occurred when the crew was attempting an emergency landing due to severe icing conditions.

Circumstances:
The crew was performing a flight from Moscow to Khabarovsk with intermediate stops in Krasnoyarsk and Irkutsk with a load consisting of 2,204 kilos of various goods and 115 kilos of mail. En route to Irkutsk, at an altitude of 3,000 meters, the left engine caught fire. The crew was able to extinguish the fire but the captain decided to divert to Nizhneudinsk Airport for a safe landing. As the crew was unable to maintain a safe altitude, the passengers jettisoned the mail bags. While at a height of some 40-60 meters with only the right engine running, the aircraft hit the tops of several larches, stalled and crashed in flames in a grain field located 5 km southeast of the Sheberta rail station, northeast of Marga. One crew member was injured while 13 other occupants were killed. The aircraft was destroyed.
Probable cause:
The fire on the left engine was the consequence of the failure of the piston #12 that broke in flight as a result of the defect of the upper part of the rod. Following this, the bolt broke and the fuel leaked into the engine and ignited while in contact with high temperature elements. It was reported that the piston failure was due to a bore default during the construction. Also, experts blamed the crew who did not take the decision to land immediately rather than trying to reach Nizhneudinsk Airport that was situated 60 kilometers from their position.

Circumstances:
Fifteen minutes after takeoff from Krasnoyarsk-Severniy Airport, the oil pressure on the left engine dropped. The crew shut down the engine, feathered the propeller and decided to return to Krasnoyarsk for a safe landing. On final approach, the speed was too high and the crew encountered problems to lower the undercarriage so the captain elected to make a go around. Few minutes later, during a second attempt to land, while at a height of some 50 meters, the aircraft stalled and crashed few hundred yards short of the runway threshold. Eighteen occupants were injured while seven others, among them four crew members, were killed.

The descent to Novosibirsk Airport was started by night and in poor weather conditions with low clouds and fog. On final approach, while at a height of 50 meters, the aircraft hit with its right wing a radio transmitter. The wing was partially sheared off and the aircraft crashed. All 16 occupants were killed.
Probable cause:
It was reported that the information related to the weather conditions and transmitted to the crew did not reflect the truth and that the approach was started in below minima conditions. Technical issues with ground communications were considered as a contributory factor.

Circumstances:
The aircraft was grounded on September 25, 1945, due to technical problems on the right engine, and was ferried for repair to the Osoaviakhim Airfield in Krasnoyarsk where it was used for some unauthorized training flights between 17 and 20 of October. On October 20, on a ferry flight from the Osoaviakhim Airfield to an airfield on the Molokov island located in the Yenisei River for repair (as the repair capacities at the Osoaviakhim Airfield were limited), the right engine caught fire some 3-4 minutes into the flight. Smoke spread in the cabin and the intoxicated pilot decided to return to the Osoaviakhim Airfield but did not manage to do it. The aircraft lost height on final approach, hit a fence and crash landed. The pilot was killed while the flight mechanic as well as the sole (unauthorized) passenger were injured.
Probable cause:
The accident was the result of the combination of several factors in flight operations and with the crew. In their report, the experts stated that the pilot conducted several training flights during the three days preceding the accident despite the fact that the right engine was not running properly. Due to lack of discipline, the pilot decided to transfer the plane to the island of Molokov with a flight mechanic and a passenger despite the fact that he was not authorized. Some confusion settled with the pilot when the right engine failed, which led him to perform inappropriate actions. The company decided to use this type of aircraft without having the adequate technical description, which had a negative impact on its maintenance and operation. Finally, the pilot did not receive sufficient training on this type of aircraft on which he was not familiarized with its performances, especially in the case of an engine failure.
