Republic of Bashkortostan

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.

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.

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.

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.

On the leg from Kazan to Sverdlovsk, while cruising at an altitude of 400 meters 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 started a go around for unknown reason. While completing a steep turn at low height, the aircraft 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.

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.
