Circumstances:
Takeoff from Moscow-Bykovo Airport was completed by night. Shortly after liftoff, during the initial climb, the captain ordered to switch off the landing light and to raise the undercarriage. The aircraft encountered problems to gain height and banked left, causing the left engine and its propeller to hit the ground. After a course of some 150 meters, the aircraft hit a telephone pole and wires and then crashed in flames in a garden. Five passengers and the radio operator were killed while 8 other people were injured, some of them seriously. The remaining then occupants were unhurt. The aircraft was destroyed by impact forces and a post crash fire.
Probable cause:
It was determined that the pilot in command suffered a spatial disorientation shortly after liftoff when the landing light was switched off. Due to the absence of ground visual reference and the poor visibility caused by night, the pilot lost his orientation and the control of the aircraft. It was also determined that the crew was tired at the time of the accident because he accumulated more than 11 flying hours per day during the last three days prior to the accident. Also, the lack of assistance on part of the copilot was considered as a contributory factor.

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:
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.

Circumstances:
While flying by night from Dudinka to Amderma, the crew encountered poor weather conditions and due to low visibility, became lost. The aircraft hit the eastern slope of Mt Netem-Pe (1,338 meters high) located 143 km north of Kharp, in the Iamalo-Nenets okrug. 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. It appears the crew was tired at the time of the accident and did not have a sufficient rest time prior to start the flight.

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.

Crew:
Cpt Vasa Vračarević 4.
Probable cause:
The crew was approaching Titograd Airport at a too low altitude, apparently to maintain a visual contact with the ground. Low visibility caused by clouds, fog and night was considered as a contributory factor. The possibility that an altimeter was defective was not ruled out.

Circumstances:
Enroute from Bucharest to Prague, the crew encountered poor weather conditions with low clouds.

Thirteen passengers were rescued, among them Arel Grigoresco, ambassador of Romania in Prague, while thirteen other occupants were killed, among them all five crew members.
Probable cause:
Due to poor weather conditions, the crew decided to fly at an insufficient altitude, neglecting navigational rules. It appears that radio failed in flight, which was considered as a contributory factor.
