Circumstances:
The crew encountered poor weather conditions while approaching Novgorod Airport with fog and a visibility below minimums. On final, the crew descended below MDA when the airplane struck the roof of a printing house and crashed in flames on a small residential building (three floors) located three km short of runway. The aircraft and the building were destroyed. All six occupants as well as five people in the building were killed.
Probable cause:
Failure of the crew to adhere to the published procedure while descending below the MDA in below minima visibility. Due to fog, the crew failed to locate the runway but continued the approach instead of initiating a go-around procedure. Weather information transmitted to the crew did not reflect the truth, which was considered as a contributing factor as well as the lack of ATC assistance.

At 0730LT, the crew informed ATC about his position and that he would start soon the aerial work. While cruising in clouds (400 to 600 meters above the ground), the airplane crashed on the east slope of Mt Yamantau (976 meters high) located 35 km east of Inzer. As the contact was interrupted with the crew and that the airplane failed to return to its base, SAR operations were initiated and the burned wreckage was found two days later about 70 meters below the summit of the mountain. All six occupants have been killed.
Probable cause:
It was determined that the accident was the consequence of a loss of control in altitude after the airplane encountered orographic currents specific to the terrain of Mt Yamantau. Despite a reaction from the crew who increased the engine power, he was unable to maintain a suitable control of the airplane.

The patient was transferred on another aircraft and once it was repaired, the aircraft was ferried to Mogilev with both pilots and both mechanics. About six minutes after takeoff, while cruising at a relative low altitude about 10 km from its departure point, the airplane entered a steep left turn, went out of control and crashed in flames at Malyye Khutora (Krasnopolye district of the Mogilev region). All four occupants were killed.
Probable cause:
It was determined that both pilots were severely intoxicated after taking part to a wedding in the afternoon. The alcohol content of the captain's blood was 2 ‰ and 4.2 ‰ for the copilot. Both mechanics had not consumed any alcohol.
