Circumstances:

During the takeoff roll at Sochi-Adler, at a speed of 220 km/h at a distance of 1,100 meters from the runway end, the aircraft's speed fluctuated for about 2-3 seconds. The captain decided to abandon the takeoff procedure and initiated an emergency braking maneuver. The airplane's speed increased to 250 km/h until the reverse thrust activated. Unable to stop within the remaining distance, the aircraft overran, lost its undercarriage and eventually collided with trees. 15 occupants, among them five crew members, were injured. The aircraft was written off.

Probable cause:

The decision of the captain to abandon the takeoff procedure was hasty as the takeoff configuration and all takeoff calculation were correct. It was determined that the speed's fluctuation at 220 km/h was the consequence of a brutal change it the wind direction and speed. Nevertheless, the aircraft was already above V1 and the takeoff should be continued.

Circumstances:

The airplane was completing a cargo flight from Krasnoyarsk to Bajkit with an intermediate stop in Yeniseysk, carrying six passengers, six crew members and a load of 3,700 kg of oranges. On final approach by night, the captain realized his altitude was insufficient and decided to initiate a go-around. He increased power on both engines but followed a wrong path with an insufficient rate of climb. At a speed of 232 km/h, the airplane struck tree tops, stalled and crashed 310 meters further on the slope of a wooded hill (410 meters high) located about 1,700 meters past the end of runway 06. A crew member and three passengers were killed while eight other occupants were injured.

Probable cause:

The captain failed to follow the published procedures related to a go-around maneuver with a too low rate of climb and a wrong path. A poor flight preparation was considered as a contributing factor as well as the fact that the captain was flying to Bajkit for the first time.

Circumstances:

On a positioning flight from Kharyaga to Ust-Tsilma, the engine failed shortly after takeoff. The crew elected to return to the airport but altitude and speed were not sufficient. After 'hopping' over a telegraph line, the left wing hit the ground and the aircraft impacted the tundra 400 metres short of runway. Both pilots and both passengers (aircraft mechanics) were killed. A day prior to the accident, the crew completed flight SU917 from Ust-Tsilma to Kharyanga via Novy Bor but the flight was interrupted in Kharyaga due to engine problems and two technicians were dispatched at Kharyaga Airport.

Probable cause:

Engine failure for undetermined reasons.

Circumstances:

Five seconds after takeoff from runway 01 at Moscow-Vnukovo Airport, while in initial climb, a fire alarm activated in the cockpit panel, informing the crew about a fire in the left engine. The crew declared an emergency, continued to climb and was cleared to return. Following several turns, the crew started an approach to runway 01 by night and marginal weather conditions. On final, the airplane descended below the MDA until it struck the ground at a speed of 350 km/h and crashed in flames in a snow covered field located along a wooded area, 1,548 meters short of runway 01. 58 passengers and a stewardess were killed while 61 other occupants were injured. The aircraft was destroyed.

Probable cause:

It was determined that the fire alarm that activated in the cockpit was false and not related to an engine fire. Analysis revealed that the temperature of the left engine compartment increased to 253° C due to the disconnection of a pipe coupled to the anti-icing system. The accident was the consequence of the combination of several wrong decisions on part of the flying crew and the following factors:
- The approach was completed by night and icing conditions in a single engine configuration,
- The total weight of the aircraft was 10,201 kg above the maximum weight allowed for landing,
- The approach was completed with a tailwind component,
- Excessive approach speed,
- Premature descent resulting in a collision with ground after passing MDA,
- Lack of crew interaction and coordination,
- The navigator failed to inform the captain about the decision height fixed at 120 meters,
- The approach was completed with the GPWS deactivated,
- The copilot failed to monitor the instruments properly, which contributed to the deviation of the airplane to the right during the last sequence until it lost altitude and impacted the ground.

22 minutes after takeoff from Tyumen-Plekhanovo Airport, while cruising at an altitude of 200 meters, the engine lost power and the airplane lost height. The crew elected to restart the engine but without success. The airplane then struck trees and crashed in a wooded area. All four occupants were injured.

Probable cause:

The cause of the accident was the internal destruction of the engine due to fatigue peeling of the nitrided layer and subsequent destruction of the teeth of the fixed gear wheel.

Circumstances:

The crew (one instructor and two student pilots) were completing a local training mission at Belgorod Airport. They departed Belgorod at 1020LT and completed several circuits over the region. While approaching the airport with the right engine out, the crew lost control of the airplane that entered a right turn then spiraled into the ground and crashed in a snow covered field located near the outer marker. The aircraft was totally destroyed and all three crew members were killed. Weather conditions were marginal at the time of the accident.

Probable cause:

Due to the extensive destruction of the aircraft, it was not possible to determine the exact cause of the accident. However, it is believed that the loss of control may have been caused by wrong informations provided by the horizons while on approach in poor weather conditions.

Circumstances:

The aircraft was engaged in a cargo flight from Chersky to Zyrianka, carrying two loadmasters, five crew members and a load consisting of eight wooden copper coils. During the takeoff roll, at a speed of 200 km/h, the pilot-in-command started the rotation (the rotation speed was calculated at 215 km/h). The airplane rotated and continued to climb until the altitude of 150 meters when it entered stall conditions. It turn to the right and crashed in a huge explosion on an hotel located near the airport. The aircraft and the hotel were totally destroyed by a post crash fire. All seven occupants were killed while no one on the ground was injured.

Probable cause:

It was determined that the stall and subsequent loss of control during initial climb was caused by the cargo shifting. Investigations revealed that the wooden copper coils were not properly installed and secured in the cabin but only fixed with the onboard winch cable. At liftoff, the wooden copper coils moved to the rear of the cabin, causing the CofG to be out of the enveloppe and the aircraft to be uncontrollable. Loadmasters failed to install and secure the wooden copper coils according to the published procedures and failed to use appropriate equipment such as nets or belts. The copilot exercised an unsatisfactory supervision of the loading while the captain decided to takeoff despite the load was improperly secured.
