Dikson

Following an uneventful flight from Dikson, the aircraft landed at Norilsk-Alykel Airport at a speed of 200 km/h. After touchdown, the crew started the braking procedure when the captain inadvertently raised the landing gear. As the gear were locked down, they remained extended but after entering the taxiway, the crew increased power and the speed reached 135 km/h when an unloading of the landing gear and a decompression of the right hand main landing gear damper occurred. This caused the right main gear to collapse slowly. The airplane went out of control, veered to the right and came to rest out of the taxiway. All 20 occupants escaped uninjured while the aircraft was damaged beyond repair.

Following an uneventful flight from Krasnoyarsk, the crew started the approach to Dikson by night and marginal weather conditions. On short final, the aircraft was too high and landed too far down the runway with a tailwind component and at an excessive speed. Unable to stop within the remaining distance available, the aircraft overran, went through an embankment at a speed of 115 km/h and eventually came to rest in a ravine. All 35 occupants were rescued, among them 8 were injured. The aircraft was damaged beyond repair.

The aircraft was completing a flight from Myachkovo to the Krenkel Airstrip located on the Heiss Island (Franz-Joseph Land archipelago, Arkhangelsk oblast) with intermediate stops in Vorkuta and Dikson, carrying six crew members, seven passengers (scientits) and various equipments for a scientific team located in Krenkel. On approach at dusk, the crew twice lost visual contact with the runway lighting. Instead of initiating a go-around, the pilot-in-command decided to continue the approach when the airplane touched down in deep snow (one meter deep) about 32 metres to the left of the runway. On impact, the nose gear collapsed, the lower part of the nose was damaged and the long-range fuel tanks in the cabin broke away, hit and killed two passengers. The other 11 occupants were injured and the airplane was damaged beyond repair.

The SP-22 Polar station was dismantled and several airplanes were dispatched to evacuate personnel and equipment. In the morning, cargo (tractors, woods and various equipment) were loaded on board the AN-12 as well as nine passengers and a crew of seven, en route to Dikson. The ice cracked in the morning and a large crack of about two meters appears, causing the takeoff distance to be 900 meters only. Thus, cargo was offloaded and the crew decided to takeoff with a total weight of 52 tons. During the takeoff roll, the captain started the rotation about 30 meters prior to the crack. Both main landing gear struck the crack, causing the aircraft to be out of control and to crash in flames. The radio navigator was killed while all other occupants were injured, some of them seriously. The aircraft was destroyed.

The final approach was completed in low clouds and marginal visibility when the airplane hit the runway surface and bounced. On impact, the undercarriage were severely damaged, the aircraft rolled for 400 meters and then veered off runway to the right before coming to rest. There were no injuries but the aircraft was damaged beyond repair.

The crew was completing a supply mission to the ice expedition christened 'Sever 7'. On approach to Nagurskoye ice strip, the pilot in command encountered low visibility due to thick fog. Rather than to divert to a suitable terrain, he tried three times to land, without success. During the fourth attempt to land, the aircraft was too low and misaligned when it struck the ground on short final. On touchdown, the left main gear was sheared off and the aircraft went out of control and came to rest. There were no casualties but the aircraft was damaged beyond repair.
