Circumstances:
The aircraft departed Mineralnye Vody on a schedule service to Ivanovo with an intermediate stop in Donetsk. Following an uneventful flight, the crew initiated the descent to Ivanovo-Yuzhny Airport. The visibility was limited due to the night and poor weather conditions. On final approach, the aircraft was not properly aligned on the glide and the copilot and the navigator attempted to inform the captain about the deviation but without success. The captain continued the approach in a wrong configuration when, at a speed of 370 km/h and a rate of descent of 6 metres per second, the left wing struck a residential building. The aircraft entered a nose-down attitude and crashed 512 metres further, some 2,450 metres short of runway 29, bursting into flames. The aircraft was totally destroyed and all 84 occupants were killed.
Probable cause:
The accident was the consequence of a wrong approach configuration on part of the crew. The captain ignored several alerts from the copilot and the navigator and failed to initiate a go-around procedure despite the GPWS alarm sounded for about 10 seconds. The following contributing factors were reported:
- Loss of altitude control in adverse weather conditions following a premature descent,
- The crew failed to follow the published approach procedures, which resulted in the aircraft approaching the airport at an insufficient altitude and at an excessive speed,
- The 4th turn was completed too late at a distance less than calculated, which caused the aircraft to deviate from the approach path with a separation (deviation) of 1,900 metres to the right of the approach path at a distance of 8,600 metres from the runway threshold at an altitude of 500 metres,
- The captain decided to continue the approach while a landing was obviously impossible,
- A total interruption of interactions within the crew during the approach procedure, which brang the captain in a delicate situation without any assistance from the other members of the crew and causing a regular loss of the altitude control,
- The crew let the aircraft passing the admissible vertical speed during the final approach,
- Failure of the crew to initiate a go-around procedure while the Ground Proximity Warning System alarm sounded for about 10 seconds,
- Excessive corrective maneuvers on part of the captain which caused the aircraft to enter a roll angle greater than the permissible limits,
- The violation by the crew of the approach pattern was facilitated by the lack of assistance from ATC at Ivanovo Airport.

Circumstances:

The aircraft then landed hard and came to a halt on the main runway. All 79 occupants were evacuated, among them five passengers were injured.
Probable cause:
It is believed the aircraft lost height on short final due to an insufficient speed.
The following contributing factors were reported:
- Poor planned approach on part of the crew.
- Poor crew coordination.
- Lack of supervision and crew cross checks.

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:
The approach to Bangkok-Don Mueang Airport was initiated in poor weather conditions with a reduced visibility due to heavy rain falls. On final, the aircraft was too low when it struck the ground and crashed about 6 km short of runway. 14 occupants were rescued while 76 others were killed. The aircraft was destroyed.
Probable cause:
It was determined that after passing the outer marker, without visual contact with the ground due to heavy rain falls, the crew passed the decision height when the aircraft struck the ground and crashed. A loss of altitude caused by possible windshear is not ruled out.
