Circumstances:
While cruising at an altitude of 11,000 meters on a flight from Omsk to Moscow, the crew was informed by ATC that the route to Vnukovo was closed due to weather deterioration and was instructed to divert to Sverdlovsk and to reduce his altitude to 10,000 meters. Two minutes later, the pilot sent a mayday message, reporting he was losing control of the airplane that entered a dive. By an angle of 80°, the airplane struck the ground and crashed in a field located along a railroad track near Kanash. The aircraft totally disintegrated on impact and all 80 occupants were killed, among them several foreign citizens such as three Sudanese, one Cambodian (Cambodian ambassador in China), eight Czech, three Romanian, one Polish, five East-German, five Hungarian, three Moroccan, two British, five French, one Iraqi and one Laotian.
Probable cause:
It was determined that the loss of control was caused by severe downdrafts, updrafts and atmospheric turbulences encountered at high altitude while changing its itinerary and altitude. The aircraft then reach a critical angle of attack before entering a dive.

Circumstances:
The crew was performing a training flight from Novosibirsk to Moscow-Vnukovo Airport with an intermediate stop at Sverdlovsk-Koltsovo Airport. While approaching Moscow, the crew informed ATC that the fuel reserves were insufficient and requested the permission to divert to the Dyagilevo Airbase located 180 km southeast of Moscow. Without checking local conditions, the flight director authorized the crew to divert to Dyagilevo. Upon arrival, the pilot was forced to make a go around due to poor weather conditions and it was then decided to divert to the Savasleyka Airbase located 200 km northeast of Dyagilevo. On final approach to Savasleyka Airfield, both engines stopped simultaneously. The airplane stalled, struck trees and crashed in a wooded area located 1,500 meters short of runway. The aircraft was destroyed and all eight crew members were seriously injured.
Probable cause:
Double engine failure caused by a fuel exhaustion.

Circumstances:
The aircraft, with TAROM color scheme but operated by the Romanian Government, was performing a flight from Bucharest to Moscow-Vnukovo with an intermediate stop at Kiev, carrying a Romanian delegation. The approach to Vnukovo was completed by night and after he cleared the inner marker, the pilot established a visual contact with the runway lights and continued the approach. At this time, he was contacted by ATC who instructed him to maintain level as his altitude was insufficient. Shortly later, at a height of about 10 to 15 meters, the airplane struck trees and crashed in a wooded area located 500 meters short of runway and 130 meters to the left of the extended centerline. Three crew members and one passenger, the Romanian Minister of Foreign Affairs Gregore Preoteasa were killed while 12 other occupants were injured, among them the futur President Nicolae Ceaucescu.
Probable cause:
The accident was the consequence of a succession of errors on part of the flying crew during the final approach that was continued at an insufficient altitude. The pilot-in-command took the decision to continue the approach procedure despite a warning message from ATC and because he established a visual contact with the runway lights. Due to low visibility and an insufficient height, this led the aircraft to struck trees and to crash. A lack of training and competences analysis was considered as a contributing factor.

Circumstances:
The aircraft took off from Warsaw-Okecie Airport on a non-stop scheduled flight to Moscow, following the normal route of flight LO232. It carried 8 passengers, 5 crew and 819 kg of mail and cargo. The flight was routine as far as Klimentiewo, 75 km west of Vnukovo Airport, and communication between the aircraft and the relevant units of the Air Traffic Control service was established. During the flight leg between Wiazma and Klimentiewo the aircraft followed its route and lowered altitude as instructed by the air traffic controller in view of the bad weather conditions (storm) in that area. Over Klimentiewo the aircraft was at an altitude of 400 m, altimeter setting 737.4 mm Hg (current QFE at Vnukovo Airport); the pilot reported sighting the ground and was cleared by the air traffic controller to descend to 300 m and to head for Vnukovo Airport. At 2307LT, i. e. 5 minutes before the scheduled time of arrival at the aerodrome, the crew requested approach clearance. The air traffic controller had transferred control of the aircraft to the approach control service ; the latter, having established contact with the aircraft, gave the pilot the QAM and cleared him for approach in accordance with the instrument approach procedure prescribed for that aerodrome. Although the pilot acknowledged receipt of the approach clearance, according to established procedure, he failed to adhere to the prescribed procedure and descended to such a low altitude that the aircraft hit the ground. The aircraft was completely demolished. Five passengers and 4 crew members were killed and 3 passengers were seriously injured.
Probable cause:
The aircraft hit the ground while flying at an excessively low altitude fol- lowing the crew's application of an approach procedure other than that prescribed by Vnukovo Airport. The bad weather conditions which set in during the night and were not forecast in the messages had their influence on the disastrous end of the flight.

Circumstances:
Enroute from Vnukovo to Leningrad, while cruising at an altitude of 900 meters in clouds, the right engine failed. Unfortunately, the crew was unable to feather the propeller and thus, was unable to maintain a safe altitude. The captain decided to divert to the Vypolzovo Airbase but radio contact with the base was impossible for unknown reason. Eventually, the pilot attempted an emergency landing in a potatoes field located in Ozerevo when the airplane crashed. Five crew members and two passengers were killed while 12 other occupants were injured. The aircraft was destroyed.
Probable cause:
Failure of the right engine in flight caused by an oil leakage due to the failure of a connection hose.

Circumstances:
The aircraft was performing a flight from Stalingrad to Moscow-Vnukovo, carrying a crew of five and 20 passengers, among them 10 citizens (women) from Norway who met antifascist people in Stalingrad and were flying back to Moscow. While cruising at an altitude of 2,200 meters in clouds, the crew informed ATC about the failure of the right engine and obtained the permission to divert to Voronezh Airport for an emergency landing. Shortly later, the right engine caught fire and while descending to an altitude of 900 meters, the right wing failed, causing the aircraft to dive into the ground and to crash about 4 km from the runway threshold. The airplane disintegrated on impact and all 25 occupants were killed.
Probable cause:
It was determined that the right engine was brand new and totalized 250 hours only. Despite this, the engine already suffered cracks and defaults. Investigations reported that a fuel leak occurred on the right engine enroute. Due to lack of oil, the engine overheated, caught fire and eventually exploded. The fire spread to its nacelle and then to the right wing that broke off few minutes later.

Circumstances:
The aircraft departed Moscow-Vnukovo at 1911LT and continued under VFR at an altitude of 1,200 meters until Kazan. The crew obtained the permission to descent to Kazan and reduced his altitude to 600 and then 300 meters. During 3 to 4 minutes, the aircraft was flying along the Volga River at an altitude of 300 meters when the crew heard a noise and both engines lost power simultaneously. In the mean time, fire erupted from the exhaust pipe and the crew elected to activate the fire extinguisher system on both engines but without success. The captain reduced his altitude in an attempt to make an emergency landing on the Volga River. The airplane crash landed on the water and eventually came to rest near the bank. 22 occupants were able to evacuate the cabin while a passenger died from drowning. The aircraft sank to a depth of 18 meters.
Probable cause:
It was determined that the aircraft collided, at an altitude of 300 meters, with several ducks. A duck hit the left engine while a second hit the top part of the cockpit, just above the windshield. The impact damaged the upper side of the flight deck and a short-circuit occurred on the magneto switch, causing both engines to stop. The crew elected to feather both propellers but this was not possible because the generator did not provide sufficient power at that time.

Circumstances:
The airplane left Moscow-Vnukovo at 1535LT for a local test flight, carrying eight crew members, pilots and engineers. After departure, the crew lost his orientation due to poor weather conditions. At this time, the ceiling was about 100 meters with an horizontal visibility estimated between 2 and 4 km. Despite the situation, the crew continued the flight and flew over the capital city for few hours, completing the test program. Weather conditions worsened during the flight, the visibility dropped to 400 meters with fog and rain. On a night approach to runway 24, the aircraft was misaligned and the pilot in command decided to make a go around. Few minutes later, while on a second approach to land, the aircraft was too low and hit trees located 1,275 meters short of runway 24, stalled and crashed. The aircraft was destroyed and all eight occupants were seriously injured. The captain, the copilot and the flight engineer died from their injuries few hours later.
Probable cause:
It was determined that the crew took the decision to carry a test flight while the weather conditions were below minima. Also, a direction finder was out of service when the crew started the flight, which contributed to the loss of orientation after takeoff. The following factors were considered as contributory:
- violation of the operator procedures on part of the flying crew,
- lack of discipline on part of the flying crew,
- poor weather conditions (below minima),
- overconfidence and arrogance on part of the captain,
- violation of the published navigation rules.

Unfortunately, this crew arrived too late and another crew from the Uzbekistan Aeroflot Division took over the airplane for a transfer to Tashkent. After takeoff, the crew failed to announce the modification to ATC, cut the route and continued at an insufficient altitude when the aircraft collided with an Aeroflot Douglas TS-62 registered CCCP-L861. Carrying four passengers and four crew members, the TS-62 just took off from Moscow-Vnukovo Airport and was climbing out bound for Moscow-Bykovo Airport. Both aircraft dove into the ground and crashed in a wooded area located 6 km southeast of the airport, in Valuevo. Both aircraft were destroyed and all 12 occupants were killed.
Probable cause:
Wrong decision on part of the Ilyushin II-12' crew who decided to modify his route without prior permission from ATC.
