Circumstances:
On final approach to Orenburg, the aircraft dropped below the glide path and the crew did not take the decision to attempt a go around. The three engine aircraft hit the ground 68 meters short of runway threshold with a positive aerodynamic force of 3 g, bounced and touched down again 635 meters further. On the second touchdown, the positive aerodynamic force was 3,9 g, causing the aircraft to brake in two. The airplane went out of control and eventually came to rest. Two crew members and one passenger were injured.
Probable cause:
Wrong approach configuration on part of the crew who failed to follow the approach checklist and published procedures. A series of errors and omissions on part of the flying crew led the aircraft descending below the glideslope and despite several alarms sounded, the captain failed to attempt a go-around manoeuvre. An inappropriate usage of approach charts, stabilizers at -5,5°, flaps at 45° and procedures violation caused the airplane to follow a wrong approach path. Also, the controller in charge of the approaches cleared the crew to land in lieu of giving the instruction to initiate a go-around.

Circumstances:
En route from Yeniseysk to Motygino, while cruising at an altitude of 900 meters in the region of the Pogromnaya River, the engine failed. The crew attempted an emergency landing when the airplane struck trees and crashed in a wooded area located 8 km north of Novoangarsk. All occupants were rescued and the aircraft was damaged beyond repair.
Probable cause:
Engine failure in flight caused by a poor quality fuel.

Circumstances:
The airplane was engaged in a flight where the crew was supposed to test various equipments, probably military ones. According to officials, in poor weather conditions, the airplane deviated from the departure climb course, collided with trees and crashed on a hilly terrain. The wreckage was found in snow about a week later. All nine occupants have been killed.
Probable cause:
Due to the extreme secret character of the mission, no information were published about the circumstances and the causes of the accident. All information related to this tragedy were immediately classified by the Soviet Authorities.

Circumstances:
The crew was completing a ferry flight from Veliky Ustyug to Vologda and initiated the descent by night and poor weather conditions with fog and reduced visibility. On short final, the aircraft passed below the glide and at a height of 20 meters, it struck trees and crashed in flames in a wooded area located short of runway threshold. The aircraft was totally destroyed by impact forces and a post crash fire and three crew members were killed while two others were seriously injured. At the time of the accident, the visibility was 700 meters, well below minimums, but the crew was informed about a visibility of 1,500 meters.
Probable cause:
It was determined that people at Vologda Airport (ATC, meteo,...) falsified weather bulletins to allow certain aircraft to land. The crew was also blamed to let the aircraft descending below the glide without any visual contact with the runway lights.

Circumstances:
The departure from Bugulma was scheduled at 0805LT but postponed first to 0900LT due to poor weather conditions en route. Shortly before takeoff at 0950LT, three additional passengers enplaned, giving a total of 15 passengers (the maximum allowed was 12). One minute after liftoff, during initial climb, at a height of 15 meters, the airplane's speed decreased to 60 km/h then it veered to the left, stalled and crashed. A passenger was killed while another one was uninjured. 15 others occupants were injured and a second passenger died from his injuries five days later, on November 16. At the time of the accident, weather conditions were considered as normal and the total weight of the aircraft and its CofG were within limits.
Probable cause:
It was determined that the loss of control during initial climb occurred after the pilot got distracted. For any reason, he adopted a wrong takeoff configuration and failed to take appropriate actions to maintain a positive rate of climb and a sufficient speed.

Circumstances:
The three engine airplane was engaged in a local training flight at Rostov-on-Don Airport, carrying five crew members, among them one instructor and two pilots who have to be trained to become captain. Following seven successful approaches to Rostov Airport, weather conditions deteriorated and the visibility passed below minimums. In such conditions, the instructor decided to continue the training cession in Krasnodar, about 250 km southwest, and was vectored accordingly. At this time, fuel reserves were estimated for 2 hours and 30 minutes of flight. Nevertheless, en route, the crew lost his orientation and due to poor ATC assistance, was unable to fly to Krasnodar and to know his exact position. About an hour later, all three engines stopped due fuel exhaustion and the crew decided to attempt an emergency landing. The aircraft crash landed in an open field, slid for dozen meters and collided with several trees before coming to rest. The wreckage was found 43 km from Tikhoretsk and all five occupants were rescued. The captain and the instructor were injured while three other occupants were unhurt. The aircraft was damaged beyond repair.
Probable cause:
The crew failed to analyze changing weather conditions en route and did not use the radionavigation and integrated navigation equipment with sufficient effectiveness. On their side, ATC based in Rostov and Krasnodar failed to adequately assist the pilots and gave them instructions that were confusing, including reporting points. Despite the fact that the air controller did not know the exact position of the aircraft, he allowed the crew to descend from 5'100 to 1'800 meters for an approach to Krasnodar while the aircraft was actually out of the airport area. The accident was the consequence of an emergency landing made necessary by the fact that the fuel reserves were exhausted. The following factors were considered as contributing:
- Poor flight organization,
- Poor preparation of the training mission,
- Lack of ATC assistance,
- Serious shortcomings in the organization of ATC in the Krasnodar and Rostov control zones.

Circumstances:
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.
Probable cause:
The wrong reaction of two passengers who decided to unfasten their seatbelt to close the cabin door, causing the CofG to be out of aft limit.
