Lensk

The single engine aircraft departed Lensk at 0813LT on a flight to Bratsk. While cruising at 4,200 metres over the cloud layer, the engine failed. The crew elected to divert to Kirensk Airport but was unable to maintain a safe altitude. Eventually, the captain attempted an emergency landing when the aircraft impacted trees and crashed in a wooded area located 37 km west of Kirensk. All nine occupants were injured and the aircraft was damaged beyond repair.

The crew was completing a positioning flight from Krasnoyarsk to Yakutsk with an intermediate stop in Lensk. The intended destination was in fact Prokovsk located about 70 km southwest of Yakutsk but the airfield was not suitable for night movements. On approach to Yakutsk-Magan Airport, the crew continued to Prokovsk where several cars were parked along the runway with their lights ON. Due to low visibility caused by night and snow falls, the crew was unable to establish a visual contact with the ground and two approaches were missed. During a third attempt to land, the aircraft collided with pine trees and power cables and crashed in an open field, bursting into flames. All three occupants were killed.

The aircraft was engaged in a cargo flight from Voronezh to Susuman with intermediate stops in Kurgan, Krasnoyarsk and Lensk, carrying four passengers, five crew members and a load of 3 tons of sausages and cheese. After departure from Kurgan Airport, a fuel pump failed and the crew decided to divert to Novosibirsk-Tolmachevo Airport where repairs were successfully conducted. En route to Susuman, while cruising at an altitude of 5,700 metres, the crew got disoriented and the radio contact were difficult. As the fuel reserves were low, the captain decided to attempt an emergency landing 75 km southeast of Zyrianka Airport. With flaps down at 38° and at a speed of 177 km/h, the aircraft crash landed and slid for 488 metres before coming to rest. All nine occupants escaped with minor injuries and the aircraft was damaged beyond repair.

The aircraft was completing a cargo flight from Petropavlovsk-Kamchatsky to Kiev with intermediate stops in Lensk and Omsk, carrying seven passengers (among them technicians), six crew members and a load of fish. Rotation was completed at night at a speed of 225 km/h and the crew immediately raised the landing gear. The aircraft climbed with a rate of 6 metres per second and after passing the runway end at a height of 70 metres, the crew selected flaps up. The aircraft entered an uncontrolled descent, struck trees (22 metres high) at a speed of 380 km/h and crashed in a huge explosion 3,903 metres past the runway end and 400 metres to the left of its extended centerline. The aircraft was totally destroyed and all 13 occupants were killed.

The single engine airplane departed Lensk Airport at 0909LT on the second leg of a flight from Vitim to Olyokminsk. About an hour later, while cruising at an altitude of 1,500 meters, the engine started to vibrate and the crew decided to attempt an emergency landing. The airplane descended into trees and crashed in a wooded area located 122 northwest of Olyokminsk, bursting into flames. All nine occupants escaped uninjured while the aircraft was destroyed by fire.

During initial climb, at a height of about 15-20 meters, the rear cabin door opened accidentally. Two passengers unfastened their seatbelt to close the door. This movement in the cabin caused the center of gravity to move past the rear limit by 37%. The aircraft reached a super critical angle of attack and at a speed of 60-65 km/h, it stalled and crashed in a near flat attitude near the runway (rate of descent estimated between six and eight meters per second). Two passengers were killed while 10 other occupants were injured. The copilot died from his injuries two days later.

Crashed in unknown circumstances near Lensk. There were no casualties.

The aircraft departed Ust-Kut Airport on a cargo flight to Mirny, carrying a load of 18 tons of cement. Few minutes after takeoff, the crew was informed that a landing at Mirny Airport was impossible due to technical problems and the captain decided, without referring to his operations, to divert to Lensk Airport where the weather conditions were considered as poor. At that time, the sky was overcast with clouds down to 600 meters, an horizontal visibility of 2,500 meters with rain and snow. The flight was continued at an altitude of 8,000 meters then the crew was cleared to descent to 3,000 meters and to start the approach to Lensk. On final, the pilot-in-command failed to realize his altitude was insufficient when the airplane struck tall trees (20 meters high) in a flat attitude, continued the descent and crashed 420 meters further in a wooded area. The wreckage was found 15,6 km short of runway threshold. The aircraft was totally destroyed and all six crew members were killed.

The aircraft departed Olyokminsk Airport at 1810LT bound for Lensk. Eighteen minutes later, while cruising at an altitude of 4,500 meters, the airplane entered an uncontrolled descent until it crashed in a near vertical attitude (80°) in a dense wooded area located 92 km west of Olyokminsk. The aircraft partially disintegrated in the air and debris scattered on a large area. There was no fire on board prior to final impact. None of the 45 occupants survived the accident.
