Circumstances:
The airplane was engaged in a special mission on behalf of the Voyekova Geophysical Observatory, carrying a crew of five and six passengers, among them three employees of the observatory. Following a successfully mission consisting of thunderstorm observation, the crew was approaching Bagdarin when he encountered poor weather conditions with low clouds and heavy rain falls. While descending to an altitude of 600 meters in clouds, the airplane struck tree tops, stalled and crashed in flames in a wooded area located on the slope of a mountain (827 meters high), about 28 km from the Bagdarin Airport. The aircraft was totally destroyed and all 11 occupants have been killed.
Probable cause:
Poor approach planning on part of the crew who failed to follow the approved procedures and adopted a wrong approach configuration, causing the aircraft to descend to an unsafe altitude over mountainous area and in poor weather conditions. The lack of visibility due to clouds and rain was considered as a contributing factor as well as a poor ATC assistance.

Circumstances:
Shortly after takeoff from Omsk Airport, while climbing to a height of 10 meters, the pilot-in-command encountered an unexpected situation and reduced the engine power, apparently to attempt an emergency landing. The airplane banked left then stalled and crashed inverted in flames in a field located 128 meters to the left of the runway and about 180 meters past its end. Two passengers and the copilot were seriously injured while 11 other occupants were killed. A day later, both passengers who survived died from their injuries.
Probable cause:
At Omsk Airport, strong winds forced a local technicians team to lock the aircraft rudder while parked on apron. Following negligences on part of the crew, takeoff was initiated with a locked rudder. The following findings were reported:
- The technicians failed to report to the crew that the rudder has been locked by ground personnel,
- The crew failed to follow the pre-takeoff checklist,
- The crew failed to conduct a visual inspection of the airplane prior to takeoff,
- The crew failed to follow the published procedures prior to takeoff,
- The crew failed to proceed to a test of the rudder, ailerons and elevators during the taxi procedure.

Aircraft flight hours:

Aircraft flight cycles:

Circumstances:
The crew was engaged in a crop spraying flight from Kursk for the kolkhoz (collective farm) im. Karla Marksa in the Kursk district of the Kursk region. The crew failed to use the full length of the runway for takeoff and tried to climb out too steeply, losing speed and height. The captain extended the flaps to 37° while flying low over a forest behind the airport's perimeter, causing additional loss of speed and height so the aircraft touched tree tops, crashed in the forest 100 metres further on (1,890 metres behind the runway threshold), caught fire and burnt out. The copilot was injured while the captain was killed.
Probable cause:
Poor flight preparation and wrong takeoff configuration on part of the pilot-in-command (captain). He failed to use the full runway length and started the rotation at an insufficient speed with en engine running too low. With flaps at 37°, this caused the airplane to adopt a nose-up attitude and a high angle of attack. The relative low experience of the copilot (90 flying hours) was considered as a contributing factor.

Circumstances:
At liftoff, the airplane entered a high nose attitude. The pilot-in-command reduced the engine power when the airplane crashed back onto the runway and came to rest. There were no injuries but the aircraft was damaged beyond repair.
Probable cause:
Poor flight preparation on part of the crew who decided to takeoff with an aircraft from which the total weight was about 248 kilos over the MTOW. Also, the CofG was out of the envelope too far aft, causing the aircraft to be uncontrollable after takeoff.

Circumstances:
After takeoff from Terney Airfield, while climbing to a height of 30 meters, the airplane adopted an excessive angle of attack. In a nose-up attitude, it banked left then stalled and crashed in flames in a potatoes field. The captain and five passengers were injured while all 10 other occupants were killed.
Probable cause:
It was determined that the crew failed to prepare the flight properly as the total weight of the aircraft was 449 kilos above the MTOW and the CofG was out of the enveloppe, too far aft. This caused the airplane to enter a high angle of attack during the initial climb and to stall and crash.
