Circumstances:
Just after liftoff, sparks were observed coming over the main front door. The climb procedure was continued and one minute and 25 seconds after takeoff, the crew retarded engine power to nominal values but both engines n°3 and 4 failed to respond and continued to turn at full power. In such conditions, the captain decided to return for an emergency landing. Following an unstable approach, the aircraft landed hard, bounced and became uncontrollable. It veered off runway and broke in two, bursting into flames. All six occupants were injured.
Probable cause:
It was determined that an electrical short-circuit had occurred in the engine control system for engines n°3 and 4, causing an asymmetric thrust. A lack of crew training and an excessive emotional stress situation for the crew were considered as contributing factors.

Circumstances:
Following an uneventful flight from Kuybyshev, the crew initiated the descent to Surgut Airport by night. The visibility was reduced due to marginal weather conditions. On approach, ATC instructed the pilot to modify his trajectory and to follow the glide as the aircraft deviated to the left. At this time, it is believed that the captain got distracted. After the crew passed the decision height, the captain continued the approach despite the fact he did not establish any visual contact with the runway lights and failed to initiate a go-around. At a height of 38 meters and a speed of 286 km/h, the aircraft passed 50 meters to the left of the threshold and the captain decided to continue. ATC instructed the crew to go-around when, one second later, the aircraft touched the ground of a snowy field some 714 meters past the runway threshold and 113 meters to the left of the runway. With a positive acceleration of 4,8 g, the aircraft lost its right wing and came to rest upside down, bursting into flames. 31 people were injured while 20 others were killed, among them the copilot.
Probable cause:
It was determined that the crew adopted a wrong approach configuration and took the decision to continue the approach after passing the decision height without establishing any visual contact with the runway lights. The following contributing factors were reported:
- The captain got distracted,
- The crew failed to initiate a go-around procedure,
- The approach lights were not activated,
- The visibility was reduced due to the night and marginal weather conditions,
- Poor flight preparation,
- Poor approach planning,
- Inaccurate information were transmitted to the crew related to weather conditions and visibilty.

Circumstances:
Following an uneventful flight from Sverdlovsk-Koltsovo Airport, the crew started the approach to Kuybyshev-Kurumoch Airport. For training purposes, the captain decided to attempt a 'blind' approach and closed the window blinds on his side, which was prohibited in such conditions. At decision height, he decided to continue and failed to realize the configuration was wrong. The aircraft passed over the runway 15 threshold and one second prior to impact, the flight engineer opened the window blinds but this was too late. At a speed of 280 km/h and with a rate of descent of 5 meters per second, the aircraft struck the runway surface with a positive acceleration of 4,8 g. This caused the left wing to be partially torn off. Out of control, the aircraft continued for about 214 meters then came to rest upside down, bursting into flames. 64 occupants were killed while 30 others were injured, some seriously. Within few hours, six of the survivors died from their injuries.
Probable cause:
Decision of the captain to attempt a 'blind' approach in violation of the published procedures. He also decided to continue the approach after he passed the decision height and failed to initiate a go-around maneuver. There was no reaction or any correction from the rest of the flying crew.

Circumstances:
The crew was performing a crop-spraying flight in the Krasny Yar district of the Kuibyshev region when the engine lost power in flight due to problems with a valve couple with cylinder n°7. The crew attempted a forced landing when the aircraft collided with trees and was destroyed. Both pilots escaped injured.
Probable cause:
Engine power loss following problems with a valve of cylinder n°7.

Circumstances:
On final approach to Izhevsk Airport, the aircraft became unstable and the captain decided to make a go-around. Few minutes later, on a second attempt to land, the aircraft rolled left and right than banked right, causing the right wing to struck the ground. At a speed of 180 km/h, the aircraft cartwheeled and crashed in a field near the runway threshold. The copilot and three passengers were killed while all 49 other occupants were injured, some of them seriously.
Probable cause:
It was determined that the loss of control on final approach was the consequence of the failure of the elevator control system following a complete disconnection of the control wiring. This was the result of improper installation and negligences during the last maintenance overhaul conducted at factory #403 at Izhevsk.

Circumstances:
While cruising at an altitude of 5,100 meters on a cargo flight from Kazan to Kuybyshev, the crew informed ATC about a fire in the center of the cabin and declared an emergency. The crew initiated an emergency descent when the aircraft partially disintegrated and crashed in an open field near Bazarnye Mataki. All four occupants were killed.
Probable cause:
The exact cause of the accident and the in-flight fire could not be determined with certainty. Nevertheless, the partial disintegration of the aircraft during the emergency descent was the consequence of aerodynamic forces that exceeded the certification of the aircraft. Strong analysis about fuel feed systems, fuel hoses and electrical cables failed to reveal any anomalies.

Circumstances:
The crew was completing a cargo flight from Novosibirsk to Kursk with intermediate stops at Chelyabinsk and Kuybyshev. Following several errors, the crew started the approach to Kursk-Vostoshny Airport with a wrong approach track. Despite the aircraft was not properly aligned on the localizer and the pilot-in-command did not have any visual contact with approach and/or runway lights, he decided to continue the approach. The airplane descended below the glide then struck trees and crashed in flames in a wooded area located 420 meters short of runway threshold and 250 meters to the left of its extended centerline. The aircraft was destroyed and all five occupants were injured.
Probable cause:
It was determined that the crew adopted a wrong approach configuration, causing the aircraft to follow a wrong approach path and descending below the decision height until it struck obstacles and crashed. The following contributing factors were reported:
- Poor crew coordination,
- Poor flight preparation,
- Crew fatigue due to multiple landings that day,
- The pilot-in-command failed to initiate a go-around,
- Lack of vertical and horizontal visibility due to low clouds, mist and drizzle.

In poor visibility, the aircraft dropped below the glide and hit tree tops some 2,500 meters before the inner marker. The aircraft stalled and crashed in flames in a wooded area. While the aircraft was destroyed, all three crew members were unhurt.
Probable cause:
Wrong approach configuration on part of the crew.

Circumstances:
On approach to Voroshilovgrad Airport, while descending from 1,200 to 600 meters, the airplane went out of control. It dove into the ground and crashed in a huge explosion in a field located 13 km from the runway threshold. The aircraft was totally destroyed upon impact and all 65 have been killed.
Probable cause:
It was determined that a portion of 13 m2 detached from the upper surface of the right wing during the approach, causing the aircraft to be uncontrollable. Investigations were unable to determined the exact cause of this 'structural' failure as no technical problems or any structural issues with rivet was apparently found.
