Circumstances:
The aircraft took off from Olenek Airport at 1651LT. While climbing to a height of 100-120 meters, the engine lost power. The captain decided to return for an emergency landing and initiated a turn to the left when the airplane stalled and crashed, one minute after takeoff. The aircraft was destroyed and all five occupants were injured.
Probable cause:
It was determined that the loss of engine power was the consequence of the malfunction of the spark plugs due to an excessive accumulation of tetraethyl plumb.

Circumstances:
The approach to Amderma Airport was initiated by night when the airplane descended below the glide. At a speed of 206 km/h, the airplane struck the ground 1,850 meters short of runway threshold and crashed in flames on a small hill located 140 meters to the left of the extended centerline. Two passengers and a crew member were seriously injured while all 40 other occupants were killed.
Probable cause:
The accident was the consequence of a series of violations on part of the flying crew who failed to follow the published procedures regarding the approach completed by night, which resulted in a premature descent, causing the aircraft to continue the approach below the glide until impact with the ground. The following contributing factors were reported:
- The real altitude of the aircraft was less than the one reported by the navigator,
- The pilot-in-command decided to continue the approach once the aircraft passed below the glide,
- The pilot-in-command failed to initiate a go-around maneuver,
- Poor crew coordination,
- The navigator in charge of the approach was under training and his instructor failed to assist during the approach maneuver,
- The total weight of the aircraft was 816 kilos above the MTOW at takeoff from Arkhangelsk.

Circumstances:
The airplane departed Kiev-Borispol Airport at 2321LT on the second leg of a flight from Odessa to Kazan. While cruising by night at an altitude of 9,000 meters and a speed of 530 km/h, the flaps extended to an angle of 30°. The airplane entered a spin and partially disintegrated at an altitude of 4,000 meters before crashing in a field located near Kirsanov. The aircraft was totally destroyed and debris were found on a wide area. None of the 63 occupants survived the crash.
Probable cause:
It was not possible to determine the exact cause of the extension of the flaps to an angle of 30° while the aircraft was in normal cruise with the autopilot system engaged. Various analysis could not define if the extension was the result of an electrical failure or a human action, voluntary or not. The most likely cause for flap release could be moving the handle of the left pilot flap control switch to the 'down' position by an angle sufficient to trigger the switch. The design of the locking device of the ZPPM-45 switch of the left pilot and its geographical situation does not exclude the possibility of an unintentional flap release, which was revealed by a one-time check of these devices on 16 others Tupolev Tu-124 aircraft.

Circumstances:
The aircraft departed Norilsk Airport in the late evening of August 23 on a cargo flight (SU22200) to Krasnoyarsk, carrying 10 passengers, a crew of six and a load of cargo consisting of six containers for a total weight of 1,920 kilos. Two hours and 18 minutes into the flight, while cruising by night at an altitude of 7,800 meters, all four engines failed simultaneously due to fuel contamination. The crew declared an emergency and initiated a descent to Yeniseysk Airport. On approach, due to low speed, the airplane lost height then struck tree tops and crashed in flames in a hilly and wooded terrain located 17,9 km short of runway. Five passengers were seriously injured while 11 other occupants, among them all six crew members, were killed.
Probable cause:
It was determined that all four engines failed simultaneously as the fuel was contaminated with water. It was also reported that the refueling system at Norilsk Airport was contaminated with water and that it had not been drained or controlled before being used. Analysis of fuel samples at the crash site showed a concentration of water and sediments between 37% and 88%. Finally, several passengers boarded without valid ticket and only upon captain permission, in violation with published procedures.

The aircraft banked right to an angle of 25° then nosed down to an angle of 30° and crashed in flames in a wooded area located 500 meters short of runway threshold. The wreckage was found 550 meters to the right of the runway extended centerline. The aircraft was partially destroyed by a post crash fire and while four passengers were seriously injured, all 10 other occupants were killed.
Probable cause:
Failure of the right engine on final approach due to the destruction of the camshaft.

At the time of the accident, the total weight of the aircraft was 358 kilos above the MTOW and the takeoff speed was too low.
Probable cause:
The accident was the consequence of the combination of the following factors:
- The total weight of the aircraft was 358 kilos above the MTOW,
- The takeoff speed was insufficient,
- Altitude density,
- High OAT at +30° C.
