Polyarnaya Aviatsiya

On a positioning flight from the Tukalan River to a remote area when the wheels got stuck in the soft ground during the takeoff run. The aircraft nosed over and caught fire. Both pilots escaped unhurt but the aircraft was destroyed by fire.

After takeoff from an area located along the Lena River, in the region of Yakutsk, while climbing to a height of 50-60 meters, the single engine aircraft banked left to 65° and nosed down to 25° then plunged into the Lena River about 200 meters offshore. All four crew members were able to evacuate the cabin but only three reached the shore as the flight engineer was drowned.

While taking off, the aircraft hit ice hummocks with its right wing and crashed. The occupant fate remains unknown.

While taking off by night at a speed of about 80 mph, the airplane encountered problem to gain height when the left wing hit an ice heap. The left main gear was sheared off and the aircraft banked left to right. The right wing hit an ice heap as well and the aircraft stalled before crashing and coming to rest 800 meters past the runway end. The captain and the flight engineer were injured while five other occupants were unhurt. The aircraft was damaged beyond repair and abandoned in situ. Without giving further details, investigators stated that the captain has had a dismissive and arrogant attitude before departure and started the flight by demonstrating overconfidence.

The seaplane was carrying one passenger and five crew members who were completing a post maintenance test flight. The crew was attempting to land in the Khimki Reservoir located northwest of Moscow when the aircraft hit the water surface, nosed down and overturned. Two crew members were killed while three other occupants were injured. The passenger was unhurt and the aircraft sank and was lost.

After touchdown in Yakutsk Airport, the airplane skidded and veered off runway to the right, lost its left main gear and completed a spin before coming to rest. While all nine occupants escaped unhurt, the aircraft was considered as damaged beyond repair due to severe damages on both left engines and the left wing as well. At the time of the accident, a crosswind of 18 km/h was blowing over the airport.

The crew was performing a cargo flight from Kresty Kolymskiye to Mys Kosistyy with an intermediate stop in Chokurdakh. Approaching this airport, weather conditions were poor and the captain decided to divert to the alternate airport of Ust-Yansk located 420 km west of Chokurdakh. On ground at Ust-Yansk, a technical problem was identified on the right engine. After repairs, some tests were made for 1 hour and 10 minutes and as they were conclusive, it was decided to proceed to Mys Kosistyy. En route, while cruising at an altitude of 2,100 meters, the crew encountered technical problems with the right engine due to a loss of hydraulic pressure. The pilot was able to shut the engine down but unfortunately, it was not possible to feather the propeller. Due to high drag, the aircraft was unable to maintain a safe altitude and the crew elected to make an emergency landing. While descending through clouds, the crew encountered icing conditions and the windscreen was covered by ice. In such conditions, the pilot was unable to distinguish the ground when the aircraft crashed in a frozen area located 16 km east of Mys Kosistyy. The wreckage and the six dead bodies were found 16 days later, on November 17, 1948.

The crew was engaged in a reconnaissance mission in the region of the Franz Josef archipelago. While returning to Amderma, the crew encountered poor weather conditions with strong headwind, fog and low visibility. In such conditions, the crew lost his orientation and deviated from the prescribed flight path to the west by 210 km. As fuel seemed to be insufficient to reach Amderma under these conditions, the captain decided to divert to Novaya Zemlya, but failed to regain orientation and missed Novaya Zemlya while flying through the Kara Straits. After being in the air for 15 hours and 12 minutes, the aircraft ran out of fuel. The crew prepared for a ditching in high seas in the Barents Sea between Varandei island, Matveyev Island and Cape Medynski Zavorot by night. An empty dinghy was found few days later but no trace of the seven crew members nor the aircraft that was lost. It was determined that the crew was able to evacuate the cabin but probably did not survive to the extreme outside conditions. Investigators did not understand why the operator and the pilots decided to perform such mission in such conditions with this type of aircraft that was not suitable for this.

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.

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.
