The aircraft was completing a cargo flight from Moscow-Zhukovsky Airport to Petropavlovsk-Kamchatsky with an intermediate stop in Abakan, carrying 13 passengers, 10 crew members and a load of 30 tons of various goods. Following a night takeoff, the aircraft climbed to a height of 200 metres then encountered difficulties to climb anymore. According to published procedures, the pilot-in-command was supposed to initiate a turn after a course of 4 km but he continued a straight-in route until the aircraft struck the slope of a snow covered mountain located 13,4 km from the runway end. The aircraft disintegrated on impact and all 23 occupants were killed.

Probable cause:

It appears that the manifest was not reflecting the truth as it was mentioned a total weight of 30 tons, an incorrect value. Because the total weight was substantially above the MTOW, the climb gradient was insufficient, resulting in a collision with a mountain that the crew was unable to locate due to the low visibility caused by night. It was also reported that the crew failed to follow the published departure procedures.

Circumstances:

After liftoff from runway 30 at Krasnoyarsk-Iemilianovo Airport, while climbing at a speed of 165 km/h, the aircraft encountered difficulties to gain height. It collided with 25 metres tall trees located about 1,000 metres past the runway end, rolled to the right and crashed in a wooded area, some 450 metres to the right of the extended centerline. Both pilots and a passenger were killed.

Probable cause:

A two-fold decrease in the operating mode of the starboard engine during takeoff, caused by the actuation of the limiting system of the starboard engine and caused, most likely, with the achievement of MCR limit values, or with a failure that caused the system to be connected with the issuance of a false signal to reduce the speed of the gas generator. The activation of the system according to the MCR should have been preceded by its connection to work, which could have occurred as a result of an out-of-order connection of the limiter unit with the automatic protection circuit breakers AZRGK TSEBO turned off or when taking off with the AZRGK TSEBO turned on. The manifestation of a refusal in this flight could be facilitated by shortcomings in the activities of the ATB personnel of the Abakan aviation enterprise. Also, the decision of the crew to takeoff while the total weight of the aircraft was 280 kilos above MTOW.

It was determined that the airplane encountered severe downdrafts and turbulences that exceeded the wing and tail certification, causing the aircraft to become uncontrollable.

Circumstances:

In the early morning, the crew completed a training flight from Abakan to Ermakovskoye with an intermediate stop in Kuragino. The airplane landed at 1000LT at Ermakovskoye Airfield then departed on a back trip to Abakan. After takeoff, the pilot climbed to a height of 10 metres then made a 180 turn bound to Abakan. While flying at low height some two km from the airfield, the airplane collided with a tall pine, lost height and crashed 150 metres further. The pilot was injured and the cadet was killed.

Probable cause:

Lack of discipline on part of the pilot who continued the flight at an unsafe altitude to clear the local obstacles.
