On approach to Saratov-Tsentralny Airport by night, the crew encountered poor weather conditions with fog, clouds from 100 to 1,000 meters and icing conditions. While approaching at an altitude of 400 meters with flaps and landing gear up, the aircraft nosed down to a 7-9° angle then rolled to the right. It descended with a high vertical speed before crashing in flames 13 km short of runway threshold. The aircraft disintegrated on impact and the wreckage was found 1,300 meters to the right of the approach path. All 57 occupants have been killed.

Probable cause:

The aircraft was approaching at an estimated speed of 240-260 km/h with flaps retracted when it rolled to the right and started an uncontrolled descent with a high vertical speed. It is believed that the loss of control was probably caused by an excessive accumulation of ice on fuselage and wings which adversely modified the aerodynamic characteristics of the aircraft. Investigations determined that the aircraft had flown in icing conditions for a period of 3 minutes and 50 seconds, resulting in an accumulation of 15 millimeters of ice. The reason why the flaps were not deployed could not be determined.

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:

The crew left Verknyaya Salda in the morning on a cargo flight to Ufa. En route, he encountered poor weather conditions and the visibility was reduced by snow falls. As the crew did not have the appropriate charts for the region, he obtained the assistance of the ATC and was vectored to Tyumen Airport. Few minutes later, while cruising at an assigned altitude of 2,100 meters, the central engine lost power and failed. Shortly later, both other engines (left and right) lost power and produced black smoke. In such conditions, the crew was unable to maintain a safe altitude and the captain decided to make an emergency landing. The aircraft hit tree tops and crashed in a wooded area located 14 km north of Mezenka. Four crew members were injured while the captain was killed.

Probable cause:

It was determined that all three engines lost power and eventually failed due to an excessive accumulation of wet snow in the carburetor and the air intake.

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:

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.
