Tupolev ANT-40 (PS-40/PS-41)

Prior to takeoff from Leningrad, the pilot was informed about weather conditions and instructed to fly not above 600 metres. The airplane departed Leningrad Airport at 1320LT on a mail flight to Moscow with two crew members on board. Shortly after takeoff, the pilot was forced to return due to an oil leak on the right tank. After repairs, the airplane took off again at 1435LT. The pilot continued at an altitude of 500-600 metres when the airplane entered clouds. Due to turbulence, the pilot decided to climb until 2,500 metres then 3,000 metres. Later, while descending, the airplane' speed increased from 270 km/h to 400 km/h and it became unstable. The flight engineer has been shaken from left to right and tried to get a radio contact with the pilot. As this was unsuccessful, he abandoned the airplane and bailed out. He was later found uninjured. The airplane continued its descent and the pilot also attempted to bail out but this was too late. His parachute failed to open in time and he was killed. The airplane crashed in a wooded area located in Oktyabrskaya, some 100 km east of Leningrad and was destroyed.

En route from Kyubyshev to Almaty, the crew encountered technical problems and attempted an emergency landing. The aircraft crash landed in a pasture located in Trostyanka, about 70 km east of Kuybyshev. The crew was uninjured and the airplane was damaged beyond repair.

The crew was completing a mail flight from Moscow to Almaty. En route, weather deteriorated with icing conditions, causing the windshield to be covered by ice and frost. To land at Kuybyshev Airport, the pilot was forced to put his head out of the cockpit, but doing so, he missed the runway. After touchdown, the airplane skidded off runway and came to rest. There were no casualties but the aircraft was destroyed.

The airplane departed Rostov Airport at 1500LT on a mail flight to Tbilisi with intermediate stops in Sochi, Sukhumi and Kutaisi. About 50 minutes into the flight, while cruising in stormy weather, the pilot lost control of the airplane that entered a dive, partially disintegrated in the air and crashed in a field at a speed of 600-700 km/h. Both crew members were killed.

The airplane departed Stalingrad at 1647LT on a mail flight to Moscow, carrying three crew members and a load of 113 kg of mail. After takeoff, the airplane entered clouds and continued his course to the northwest. After flying a distance of about 350 km, while cruising at an altitude of 4,000 metres in clouds, the airplane entered an uncontrolled descent and crashed in a field at a speed of 750-800 km/h. All three occupants were killed.

The airplane departed Moscow at 0605LT on a cargo flight to Mineralnye Vody with an intermediate stop in Kharkiv, carrying three crew members. The pilot continued at an altitude of 300 metres and at a speed of 290 km/h when weather conditions deteriorated with low clouds and rain falls. Without any radio contact with the ground to obtain a weather briefing, the crew continued to the south and passed over Tula at 0653LT. Shortly later, the crew encountered foggy conditions and was unable to locate his position so the captain decided to return. Flying to low in fog, the airplane impacted trees at a speed of 220 km/h and crashed into a ravine. All three crew members were killed.

The aircraft disappeared in the region of Arkhangelsk while completing a mission with four crew members on board. SAR failed to find any trace of the aircraft nor the crew. The wreckage was eventually found by walkers in early 90's in an isolated area.

While cruising at an altitude of 5,000 metres, the airplane entered an area of cumulonimbus. Due to severe atmospheric turbulences, the airplane became uncontrollable and started to lose altitude. The captain ordered his crew to bail out and abandoned the airplane that dove into the ground and crashed in the taiga near Birakan. The pilot was found alive but both other crew members were killed as they did not bail out.

The twin engine aircraft departed Tbilisi at 0442LT on a cargo flight to Moscow with an intermediate stop in Rostov with three crew members on board. 33 minutes into the flight, radio contact was lost after the airplane impacted the slope of a mountain located 22 km north-northeast of Napareuli. As the airplane failed to arrive in Rostov, SAR operations were initiated. On 28 October 1938, the wreckage was found by two locals in a ravine. All three crew members were killed.
