Circumstances:

Following an uneventful flight from Sverdlovsk-Koltsovo Airport, the crew started the approach to Kuybyshev-Kurumoch Airport. For training purposes, the captain decided to attempt a 'blind' approach and closed the window blinds on his side, which was prohibited in such conditions. At decision height, he decided to continue and failed to realize the configuration was wrong. The aircraft passed over the runway 15 threshold and one second prior to impact, the flight engineer opened the window blinds but this was too late. At a speed of 280 km/h and with a rate of descent of 5 meters per second, the aircraft struck the runway surface with a positive acceleration of 4,8 g. This caused the left wing to be partially torn off. Out of control, the aircraft continued for about 214 meters then came to rest upside down, bursting into flames. 64 occupants were killed while 30 others were injured, some seriously. Within few hours, six of the survivors died from their injuries.

Probable cause:

Decision of the captain to attempt a 'blind' approach in violation of the published procedures. He also decided to continue the approach after he passed the decision height and failed to initiate a go-around maneuver. There was no reaction or any correction from the rest of the flying crew.

Circumstances:

During the takeoff roll on the gravel Airstrip at Ust-Maya Airstrip, after passing V1, the left turbocompressor lost power then the engine stopped, 1,8 second before V2 speed. Power on the right engine was increased till 96% and the crew continued the takeoff procedure. Liftoff was completed at a speed of 160 km/h then the aircraft climbed to a height of 50 meters and entered a left turn. Slowly, the altitude dropped and the aircraft eventually crashed in the Aldan River about 270 meters offshore. The wreckage sank and was found 31 hours later. All 14 occupants were killed.

Probable cause:

It was determined that the failure of the left engine was the consequence of errors on part of the crew who failed to follow the pre-takeoff engine checklist. The aircraft's speed at takeoff was insufficient and the engine failure occurred at a critical stage of the takeoff procedure, causing a loss of controllability after liftoff. During climbout, the speed decreased because the crew did not raise the landing gear due to high workload caused by an emergency situation.

Circumstances:

The single engine aircraft departed Yerevan-Erebuni Airport at 1047LT on a cargo flight to Kamo, carrying two pilots and a load of 140 kilos of mail and various goods. At that time, weather conditions were considered as good. Six minutes later, the crew informed ATC about his position at an altitude of 1,800 meters and was cleared to climb to 2,400 meters. Then the aircraft entered a right turn and struck the south slope of Mt Gantusar (2,299 meters high) about two km northeast of Jraber. The wreckage was found at an altitude of 1,915 meters and both pilots were killed. It was reported that the visibility at the accident site was about 60 meters due to thick fog.

Probable cause:

It was determined that weather conditions deteriorated en route with limited visibility due to foggy conditions, and the crew took the decision to continue the flight in below minimums visibility instead of returning to Yerevan Airport.

Both occupants were injured.

Probable cause:

Decision of the captain to continue the descent in below-minimum weather conditions. The crew failed to establish visual contact with the ground.

The aircraft departed Khabarovsk on a mail flight to Kurung, a gold mine located in the Konder Mountain Range.

Both pilots were killed while both other occupants were injured. The mission did not provide to jettison the mail bags but was arbitrarily changed by the captain.

Probable cause:

The crew misjudged the distance with trees while jettisoning mail bags at low height.
