Circumstances:

Shortly after takeoff from Aldan Airport, while in initial climb at a speed of 160 km/h, the right engine failed. The crew elected to make an emergency landing on a small hill located six km from the airport and reduced his altitude when the right wing struck trees and the roof of a barn before crashing in flames. All occupants were evacuated safely while the aircraft was destroyed by a post crash fire.

Probable cause:

Due to the fact that the right engine was totally destroyed by fire, investigations were unable to determine the cause of the failure that occurred during initial climb.

The aircraft was destroyed and the pilot, sole on board, was killed.

Probable cause:

It was determined that the pilot was intoxicated and that the alcohol concentration in his blood was 3,1‰.

Circumstances:

The crew departed Moscow-Sheremetyevo Airport on a local test flight in which he had to turn off all generators in order to know the maximum life of batteries. On approach, while completing a turn at an altitude of 400 meters, both engines failed simultaneously. The crew elected to restart the engine but without success so the captain elected to ditch the aircraft into the Ikshinskoye Reservoir (Moscow Canal) located 18 km north of Sheremetyevo Airport. The aircraft was partially submerged but recovered and all five crew members escaped uninjured.

Probable cause:

It was determined that both engines failed because during the test, all electrical systems were out of order. The crew forgot that the fuel transfer system was unserviceable as well and that the fuel should be transferred manually. Such situation forced the crew to ditch the aircraft.

Circumstances:

Shortly after takeoff from Okha Airport, while on a cargo flight from Okha to Tsimmermanovka, the single engine airplane entered thick fog at a height of some 35-40 metres. The pilot decided to make a 180 turn when the airplane lost speed, stalled and crashed on the shore of the Pyervaya Bukhta Bay located northwest of the airport. The aircraft was destroyed by impact forces and a post crash fire and both pilots were killed.

Probable cause:

Loss of control and aerodynamic stall during the last turn due to an insufficient speed. The pilot inexperience in clouds and the presence of low clouds were considered as contributing factors.

Probable cause:

The engine failure was caused by soot deposits in the inlet valves.

Circumstances:

The airplane was engaged in a weather survey mission over the Baltic sea and was carrying two passengers and a crew of six. While returning to his base at Kaliningrad-Khrabrovo Airport, the crew failed to set the altimeter properly, causing the aircraft to approach the land at an insufficient altitude. In low clouds, the pilot-in-command did not realize his altitude was too low when the airplane struck trees, lost height and crashed in flames 200 meters further onto a school. The airplane was totally destroyed by impact forces and a post crash fire as well as the school building. All eight occupants on board the aircraft were killed as well as 27 people on the ground, 23 children and three adults. Two other children were seriously injured.

Probable cause:

Wrong altimeter setting caused the aircraft to fly at an insufficient altitude. Lack of visibility due to low clouds and poor ATC assistance was considered as contributing factors.
