Circumstances:
Following an uneventful flight from Moscow-Domodedovo, the crew started a night approach to Krasnovodsk Airport. The visibility was reduced due to the night combined with clouds down to 400 meters. The copilot was the pilot-in-command and he completed the approach at a speed of 270 km/h with flaps down at 28°. During the last segment, flaps were downed to an angle of 45° when the rate of descent increased to 10 meters per second. At a height of 30 meters, the copilot did not have visual contact with the runway but the captain decided to continue the approach. At an excessive speed of 275 km/h, the aircraft touched down 3 meters to the left of the runway centerline. It bounced, rolled for few hundred meters and came to rest on the main runway, broken in two. Eleven passengers were killed, 120 people were injured while 15 other escaped uninjured.
Probable cause:
Wrong approach configuration on part of the pilot-in-command (copilot) who continued the approach after passing the minimum descent altitude without any visual contact with the runway.
The following contributing factors were reported:
- Excessive approach speed and rate of descent,
- Poor approach planning and landing preparation,
- Lack of crew coordination,
- Lack of supervision on part of the captain,
- The crew failed to initiate a go-around procedure,
- Poor visibility due to the night and low clouds.

Circumstances:
The aircraft was completing a cargo flight from Sukhumi to Krasnovodsk with intermediate stops in Krasnodar and Rostov-on-Don, carrying 12 passengers (pilots and engineers), four crew members and a load of one ton of mandarins and Christmas trees. Upon departure from Rostov-on-Don Airport, weather conditions were poor due to the night and fog, reducing the vertical visibility to 60 meters and the horizontal visibility to 720 meters. Rotation was made after a course of 750 meters at a speed of 233 km/h. While climbing to a height of 170 meters, at a speed of 320 km/h, the captain requested the flaps to be raised when the aircraft lost height and initiated a descent with a positive acceleration of 1,5 G and with a rate of 5-7 meters per second. In a nose-down attitude and at a speed of 405 km/h, the airplane struck pine trees and crashed in a wooded area located 5 km from the airport, bursting into flames. The accident occurred one minute and 40 seconds after takeoff. The burned wreckage was found 1,180 meters to the left of the approach path. The aircraft was destroyed and all 16 occupants were killed.
Probable cause:
It was determined that the total weight of the aircraft at the time of the accident was 943 kilos above MTOW while the CofG was within limits. Investigations revealed serious shortcomings in the organization and preparation of the flight as well as the training of the various crew members.

Circumstances:
On approach to Krasnovodsk Airport by night, the crew encountered marginal weather conditions and at an approximate altitude of 300 meters while on a distance of 5 km from the airfield, the aircraft's speed dropped from 260 km/h to 200 km/h with a rate of descent of 2,5 meters per second. The crew elected to correct this configuration but the aircraft continued to descend until it struck, at a speed of 150 km/h, a rocky cliff situated on the shore of the Caspian Sea, some 159 meters above sea level and located about 4,700 meters short of runway threshold. Upon impact, the right engine and the right wing were torn off, the aircraft bounced and then crashed in flames few dozen meters further. Two crew members and 21 passengers were killed while 15 other occupants were injured.
Probable cause:
It was determined that the aircraft was caught by orographic turbulence on final approach whose speed was about 30 meters per second (108 km/h). This caused the aircraft to lose altitude and speed and any correction from the flying crew was unsuccessful. The following contributing factors were reported:
- Lack of knowledge on part of the meteorologist about the characteristics of such specific climate phenomenon,
- The absence of a system able to detect such phenomenon,
- The crew inexperience in such flight conditions.

Circumstances:
The aircraft departed Krasnovodsk Airport at 1804LT and shortly after takeoff, the crew was informed about weather conditions at destination with a sand storm and a visibility limited to 1,000 meters. En route, while cruising at an altitude of 6,000 meters, weather conditions worsened and the crew obtained the permission to modify his route. At a distance of 25 km from Ashgabat, the crew started the descent and reached the altitude of 400 meters when he reported the runway lights in sight. Shortly later, the airplane became unstable and lost height. It banked left to an angle of 7°, struck power cables and a concrete post. Out of control, it banked left to an angle of 30°, stalled and crashed in flames 1,012 meters short of runway threshold. Eight crew members and four passengers were killed while 42 other occupants were injured. The aircraft was destroyed by impact forces and a post crash fire.
Probable cause:
Wrong decision on part of the crew who continued the approach in below minima weather conditions. Errors on part of ATC were also reported as they cleared the crew to land in below minima weather conditions and failed to divert the crew to another airport. It was also determined that the information transmitted to the crew relating to weather conditions at destination did not reflect the truth, which was considered as a contributing factor.
