Circumstances:
En route from Tyumen to Ufa, while cruising at an altitude of 10,600 meters, the fire warning light came on, indicating smoke in the rear cargo compartment. The presence of smoke on board was confirmed but the crew was unable to identify the source of fire. The crew was cleared to initiate an emergency descent and to divert to Pervouralsk Airport. On final approach, the situation deteriorated on board and as the captain realized he could not reach the airport, he attempted an emergency landing in a snow covered area. Upon landing, the aircraft bounced twice, struck an irrigation equipment, went out of control and crashed 3 km from the Pervouralsk Airport. Four crew members and 23 passengers were killed while all other occupants were rescued.
Probable cause:
A short-circuit occured in an electrical installation located in the rear compartment of the aircraft, due to the overheating of a cable with faulty isolation.

Circumstances:
Four minutes after take off from Taraz Airport, the crew encountered freezing fog and severe icing conditions and decided to return to Taraz. Shortly later, the engine lost power and the aircraft rolled to the left to an angle of 20-25° then crashed on the embankment of a canal located some 7,5 km northwest of Taraz Airport. It eventually came to rest upside down in one meter deep water. A pilot was killed while all 11 other occupants were injured.
Probable cause:
It was determined that the engine lost power after the carburetor iced. The poor weather conditions including freezing fog and severe icing conditions have not been forecasted by the met office.

Circumstances:
Following an uneventful flight from Perm, the crew started the descent to Sovetskiy Airport and was informed about the weather conditions at destination with ceiling down to 80 meters and an horizontal visibility estimated to 2 kilometers, which was below minimums. Despite this situation, the crew decided to continue the approach and deliberately passed below the minimum descent altitude probably to establish a visual contact with the ground. On short final, the aircraft struck tree tops (25 meters high), banked right and crashed in a wooded area located 700 meters short of runway 30, about 250 meters to the right of its extended centerline, bursting into flames. Eight passengers were rescued while 32 other occupants were killed.
Probable cause:
It was determined that the accident was the consequence of a wrong approach configuration of the flying crew who decided to continue the approach in below weather minimums and passed the MDA until the aircraft contacted trees and crashed.
The following contributing factors were reported:
- Poor approach planning,
- Unsatisfactory crew interactions,
- Poor distribution of tasks among the flight crew,
- Violation of minimums,
- The crew decided to continue the approach after passing the MDA,
- The crew failed to initiate a go-around procedure.

Circumstances:
The four engine aircraft departed Ulyanovsk on a cargo flight to Leninakan, carrying 5 passengers, 10 crew members and a load of 37,2 tons of construction materials and tools. The crew was cleared to descend to 3,300 meters then ATC transmitted the airport pressure being 637 mm Hg. The crew misunderstood this pressure value and the altimeters were mistakenly set at 736 mm Hg. This caused a gap of 1,100 meters and the aircraft continued the approach with a vertical speed of 10 meters per seconds. After passing below the glide in limited visibility due to the night, while at an altitude of 270 meters, the GPWS alarm sounded. The flight engineer realized the mistake and informed the captain 19 seconds after the first alarm sounded. For unknown reasons, the pilot failed to initiate any corrective action and 10 seconds later, the aircraft struck the mountain at a speed of 440 km/h and disintegrated on impact. All 15 occupants were killed.
Probable cause:
The accident was the consequence of the following factors:
- Wrong altimeter setting on part of the crew with a value of 736 mm Hg pressure instead of the actual 637 mm Hg, causing the aircraft to descend below MDA,
- Failure to use the radio altimeters, which deprived the crew of additional information about their descent below MDA,
- Failure of the crew to respond to the recommendation by the flight engineer to climb and to initiate appropriate corrective actions,
- This was the instructor captain's first flight into Leninakan and the student pilot's (in the right hand seat) first flight on an Il-76,
- Poor crew resource management,
- Lack of crew training regarding the actions to be taken in case of a GPWS warning.
