Circumstances:
Just after liftoff, while climbing to a height of 2-3 meters, the aircraft stalled. As the undercarriage have been raised, the aircraft hit the ground on its belly, causing the propeller of the right engine to be sheared off. A blade went through the fuselage and penetrated into the cabin, killing a passenger. The aircraft slid for several hundred yards, lost its left wing and left engine before coming to rest 491 meters past the runway end. Five passengers were injured and the aircraft was written off.
Probable cause:
The accident was attributed to a lack of coordination within the flight crew. It was determined that the flight engineer mistakenly reduced the engine power shortly after liftoff, causing the speed to drop and the aircraft to stall. The captain's lack of training was considered as a contributory factor.

The cockpit separated from the rest of the fuselage, the aircraft came to rest and sank. Three passengers, two women and one child, were killed while 17 other occupants were rescued, five of them seriously injured. The aircraft was a total loss.

Circumstances:
Following an uneventful flight from Petropavlovsk-Kamchatsky-Yelizovo Airport, the crew started the descent to Magadan in poor weather conditions. During the final approach, at a distance of 13 km from the runway threshold, the captain was unable to locate the runway and decided to descend to 500 meters, the decision altitude. Unable to establish a visual contact with the runway, he decided to abandon the approach, started a go around and diverted to the Seymchan Airport located some 350 km north of Magadan. Few minutes later, while cruising in poor visibility, the aircraft hit the slope of Mt Marchekanskaya (707 meters high). A passenger was seriously injured while eight other occupants were killed. It appears the aircraft hit the mountain 70 meters below the summit.
Probable cause:
The accident was the result of a controlled flight into terrain in poor visibility due to low ceiling. It was reported that, at the time of the accident, the person in charge to transmit weather information to the crew and based at the airport of Magadan was intoxicated.

Circumstances:
Approaching Bodaibo, the crew lost his orientation due to low visibility caused by poor weather conditions (snow falls). The captain decided to reduce his altitude and followed the Vitim River to join Bodaibo Airport at a height of 100 meters. The aircraft hit the water surface and crashed in a huge explosion into the river off Mamakan, about 13 km southwest of Bodaibo. A passenger was injured and rescued while all 28 other occupants were killed.
Probable cause:
The accident occurred in flight conditions that were below published minima. It was reported that the weather prediction were not efficient and did not reflect the truth. The pilot took the wrong decision to continue and to descent in such poor weather conditions.

Circumstances:
During the takeoff roll, the aircraft veered off the center line to the right as the rudder trim has not been set to neutral position before takeoff. The crew failed to abort the takeoff procedure and about 30 seconds after liftoff, during initial climb, the right wing hit a telegraph line and collided with the pole of a high voltage power line. Out of control, the aircraft stalled and crashed. The mechanic was killed while 13 other occupants were injured. The aircraft was destroyed.
Probable cause:
The crew failed to prepare the flight properly and did not follow the pre departure checklist. In such conditions, they did not realize that the rudder trim was not set in neutral position, causing the aircraft to veer off the runway center line during the takeoff roll.

Circumstances:
An Aeroflot LI-2 registered CCCP-L4279 made an emergency landing near Tynda on April 20. A day later, a Deputy from the Amur Region decided to conduct a mission to help and forced the crew to takeoff despite the fact that weather conditions were below minima. The aircraft left Takhtamygda Airport at 1550LT. About twenty minutes later, the right engine failed. The crew was forced to feather the propeller and the captain decided to return to his departure point. Shortly later, while losing altitude, the aircraft hit tree tops with its propeller while the left elevator hit a telephone pole. The aircraft stalled and crashed. Three crew members, among them the captain, were killed while three other occupants were injured.
Probable cause:
Failure of the right engine in flight. The crew was forced to conduct the mission by a local Deputy despite the fact that weather conditions were below minima at the time of the accident.

Following the disappearance of a LI-2 registered CCCP-N444 on March 7, rescue operations were conducted and dispatched. Unfortunately, due to poor weather conditions (heavy snow falls), most of the crew were forced to stay on the ground. That day, a crew decided to make a sortie but the runway at Vorkuta Airport has not been cleared of snow. The captain ask three crew members to seat in the rear of the cabin and started the takeoff procedure on a snow covered runway (up to 30 cm of snow). After a course of about 700 meters, the aircraft lifted off but failed to gain height due to an insufficient speed. After passing the runway end, the aircraft hit the roof of a house, lost an engine, stalled and crashed in a field. All six crew members were injured and the aircraft was written off.

As the aircraft failed to arrive, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft was found. Walkers found the wreckage in an isolated area on September 17, 1950. All 20 occupants were killed.

Circumstances:
The crew left Chelyabinsk Airport at 1215LT, established contact with RDS Koltsovo and was instructed to proceed to the altitude of 1,500 meters, although this was lower than the minimum safe altitude of 2,100 meters on the route Chelyabinsk - Kazan. An hour later, the crew encountered poor weather conditions with a cloud base at 200 meters, heavy snow falls and an estimated horizontal visibility less than 4 km. While cruising at the altitude of 1,145 meters, the twin engine aircraft hit the slope of Mt Taganay located about 20 km north of Zlatoust. The wreckage was found in an isolated and mountainous area a day later, the aircraft was destroyed by impact forces and a post crash fire and all six occupants have been killed. The aircraft was carrying a load of various goods consisting of grinding wheels, boxes and a furnace-type PET-8 for a total of 2,298 kilos.
Probable cause:
The crew was authorized to fly at an altitude of 1,500 meters while the minimum prescribed altitude was fixed at 2,100 meters. It was reported that weather datas compiled prior to the flight were incomplete in that the person in charge of preparing the file for the crew remained asleep. Despite this situation, the crew decided to leave the airport of Chelyabinsk while they had no specific information about the weather and although they have not been cleared to land in Kazan Airport.

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.
