Aircraft flight hours:

Circumstances:
The crew was engaged in spraying mission on behalf of a local sovkhoz located between the villages of Pryutovo and Aksakovo. The night preceding the accident, the crew failed to take a sufficient rest time. Few crop spraying flights were performed in the morning and during the lunch break, the crew drunk a lot of vodka with local farmers and started new rotations in the afternoon with illegal passengers on board. While flying at a height of about 10 to 15 meters, the aircraft banked left to an angle of 50° and crashed in a field. The captain and a passenger were killed while seven other occupants were seriously injured.
Probable cause:
Loss of control in flight caused by an intoxicated crew whose capacities were reduced by alcohol consumption. The crew decided to embark seven farmers for a local tour which was considered as non compliant.

Circumstances:
The takeoff from Ufa Airport was completing in marginal weather conditions and the airplane was unable to gain sufficient speed. Despite the situation, the captain decided to rotate and immediately after liftoff, the aircraft adopted a high angle of attack, causing the base of the tail to struck the ground. The aircraft bounced several times then crash landed, overran and came to rest in a garden located 290 meters past the runway end and 220 meters to the left of the extended centerline. The aircraft was destroyed and all four crew members were seriously injured. Five hours after the crash, the captain died from his injuries and 38 hours later, the radio operator died.
Probable cause:
Poor flight preparation on part of the crew who decided to takeoff with a contaminated aircraft. At the time of the accident, the wings, stabs and tail were recovered with an excessive accumulation of snow which reduced drag, limited thrust and performances and modified the aerodynamic.

Circumstances:
One hour and 35 minutes after its departure from Kuybyshev Airport, bound for Sverdlovsk, the oil pressure on the left engine dropped and the crew decided to shut it down and to feather the propeller. The captain decided to divert to Ufa for a safe landing but due to low clouds, he was unable to locate the airport. When the aircraft broke through the cloud layer, it was in fact above the city and when the crew increased power on the right engine, it failed because it overheat. In such conditions, the captain made a turn to leave the area and continued to the Belaya River to attempt an emergency landing. Eventually, the aircraft hit tree tops and crashed in flames in a wooded area near the river bank, killing all seven occupants.
Probable cause:
Wrong decision on part of the crew who cut the wrong engine after failure.

Circumstances:
The crew was performing a cargo flight from Chelyabinsk to Kuybyshev with a load of various goods for a total weight of 2,543 kilos. About 50 minutes after its departure from Chelyabinsk Airport, while approaching the Ural mountains at an altitude of 700 meters, the crew realized he would not be able to overfly the mountain range so he made a turn to the left and slowly climbed to 1,200 meters. Few minutes later, the aircraft encountered katabatic winds, snow falls, strong winds and turbulences. As the crew was unable to maintain a safe altitude and to overfly the mountain range, the captain decided to attempt an emergency landing. At a speed of 65 km/h, he made a last turn to the left when the aircraft hit tree tops and crashed in flames in a wooded area located on the slope of a mountain. Three crew members were unhurt, one was slightly injured while the female copilot was killed, apparently by a heart attack. The aircraft was partially destroyed by a post crash fire. The aircraft was a Tupolev G-2, a cargo version of the ANT-6.

Circumstances:
On the leg from Kazan to Sverdlovsk, while cruising at an altitude of 400 metres in clouds, the crew encountered severe icing conditions and decided to divert to the Yanaul Airport, in the Republic of Bashkortostan. On final approach, the pilot-in-command initiated a go around procedure for unknown reason. While completing a steep turn at low height, he lost control of the airplane that stalled and crashed on a meat processing plant. All five crew members and five passengers were killed while two other passengers were seriously injured. The aircraft was destroyed.
Probable cause:
The main cause of the accident was severe icing of the aircraft.
The following contributory factors were identified:
- The crew's decision to fly into clouds and to perform low-altitude turns with an iced-up aircraft.
- The meteorologist at Kazan Airport, who issued a weather forecast without indicating the possibility of icing in the clouds on the Kazan-Krasnufimsk route.
- The captain and flight instructor, who performed low-altitude turns with an iced-up airplane and allowed the flight to continue in the clouds with intense icing.
- The Kazan Airport controller, who superficially familiarized himself with the weather conditions. Seeing the unstable weather along the route, he made the ill-advised decision to transfer responsibility for the flight to the captain, writing a note in the weather report about landing in Yanaul in case of bad weather, instead of a specific order to fly above the clouds, because in Sverdlovsk, according to the forecast, there was high cloud cover of 5 to 10 points.

Aircraft flight hours:

Circumstances:
The airplane departed Ufa Airport in the early morning on a weather data operation. After reaching the altitude of 3,500 metres, the pilot returned to the airport but the visibility deteriorated due to fog that developed about 40 minutes after takeoff. The pilot descended to a height of 110 metres to establish a visual contact with the airport. As this was not possible, he decided to climb when, at a height of about 170 metres, the airplane collided with the mast of a radio station. It partially disintegrated in the air and crashed near the airfield. Both occupants, a pilot and a meteorologist were killed.
Probable cause:
The accident was caused by the combination of the following factors:
- Lack of discipline on part of the pilot, who violated instructions and failed to comply with oral instructions from the head of Ufa Airport and his deputy, to divert to Birsk Airport or other nearby sites in the event of airport closure. Despite the airfield was covered with fog, the pilot attempted to land.
- The meteorologist on duty at the Ufa AMSG did not provide a precise weather forecast for the near future. The weather report given to the pilot indicated flying conditions, but 40 minutes after takeoff, the airfield was completely covered by rapidly approaching fog. The weather forecast was based on the 19-hour synoptic chart of 09OCT42, and the one-hour synoptic chart of 10OCT42 was not provided due to lack of data.
- Insufficient organization of atmospheric sounding flights at Ufa Airport, expressed by the fact that detailed instructions were not drawn up in the local instructions for conducting flights over the aerodrome.
- The real cause of the accident was the presence of obstacles on the aerodrome's approach runway (206 metres-high radio masts) which did not meet the requirements of the aerodrome's maintenance manual.

Circumstances:
Named 'Le Trait d'Union II', the aircraft departed Paris-Le Bourget Airport on 11SEP1931 for a nonstop flight to Tokyo, the second attempt for this crew. A first attempt was made last 14 of July but the aircraft crashed in Sherbati, Russia. While cruising east of Ufa, over the Ural Mountains, the crew encountered problems while flying in poor weather conditions. Marcel Doret asked his colleagues to take their parachute and bail out. He bailed out few seconds later and landed safely when the aircraft crashed and was destroyed. At this time, he realized his both friends remained in the cabin and did not bail out for unknown reasons. Both aviators Joseph Le Brix et René Mesmin were killed.
