Circumstances:
The twin engine aircraft departed Kimry-Borki Airport on a local skydiving flight, carrying 23 skydivers and two pilots. At an altitude of 3,800 metres, 11 skydivers prepared to jump and moved through the rear of the cabin. While four of them jumped out, the aircraft stalled from the tail and nosed up then entered an uncontrolled descent. At an altitude of about 2,000 metres, the aircraft suffered a structural failure and broke up. Several skydivers were thrown out then the aircraft crashed in a snow covered forest located two km from the airfield. Nine skydivers and both pilots were killed while all other occupants were found alive. The aircraft was totally destroyed.
Probable cause:
It was determined that the aircraft was operated in illegal conditions at the time of the accident. On board were 23 skydivers while the aircraft was certified for 12 skydivers maximum. At the time of the accident, the total weight of the aircraft was 618 kilos above MTOW and the CofG was well beyond the rear limit (around 35%), especially when the 11 skydivers moved through the rear of the cabin. Some of the skydivers were seating on the floor and one was in the toilets.

Circumstances:
The crew was performing a positioning flight from Kimry-Borki to Moscow-Zakharkovo. Few minutes after takeoff, the left engine lost oil pressure and power. The captain elected to make an emergency landing but the aircraft crashed in a wooded area located in Taldom, about 13 km southeast of Borki Airport. The aircraft was destroyed and all five crew members were injured. At the time of the accident, weather conditions were poor with a cloud base at 100 meters and an horizontal visibility limited to two km. It appears that the crew did not receive any permission to complete this positioning flight to Moscow.
Probable cause:
It was determined that the oil leak and loss of power and the left engine was caused by a faulty assembly and wrong installation. Also, the left engine has not been properly tested after installation. The oil leak caused the failure of a pump and then a loss of power on the left engine. Inappropriate reaction and poor techniques on part of the crew was considered as a contributory factor.
