The airplane entered a dive and spiraled to the ground. At an altitude of 5,000 meters, some elements of the upper wing surface and the stabilisers detached and the airplane disintegrated in the air before crashing in a steppe located about 84 km south of Semipalatinsk. Wings and stabilisers parts were found at a distance of some 3.5 km from the crash site. All 63 occupants have been killed.

Circumstances:
While on a positioning flight from Osinovka-Andreyevka to Almaty for crop-spraying operations for the sovkhoz (state farm) 'Andreyevski' with 2 mechanics and 2 local guides on board, the captain decided not to circumvent the Chubundy (Shybyndy) mountain ridge but to make a straight-in flight. Few minutes later, he encountered below-minima weather conditions and decided to return to Andreyevka but this was too late. Shortly later, while completing a turn in clouds at an altitude of 1,200 meters, the single engine airplane collided with the summit of a ridge located about 15 km northeast of Andreyevka Airport and crashed. Injured, the copilot walked down the mountain to find help. The captain was killed while all five other occupants were injured.
Probable cause:
Controlled flight into terrain caused by wrong in-flight decisions on part of the captain.

Circumstances:
The airplane was completing a flight from Kyzymshek to Shymkent with an intermediate stop in Shulakkurgan. Prior to leave Shulakkurgan, the crew was informed about the poor weather conditions en route and the captain request for another itinerary. He was cleared by ATC to take another route to the west but few minutes after takeoff, the crew encountered poor weather conditions and failed to return. While cruising in low clouds and rain showers, the single engine airplane struck the slope of a mountain at an altitude of 454 meters and located in the Karamuryn Mountain Range. As the airplane failed to arrive at destination, SAR operations were conducted and the burnt wreckage was found two days later about 35 km northeast of Shieli. All 13 occupants have been killed.
Probable cause:
The accident was the consequence of a controlled flight into terrain in below-minima weather conditions. The captain decided to conduct the flight in poor weather conditions and failed to return, violating all procedures in place. ATC cleared the crew to take another route to the west which was also irresponsible and the meteorologist published bulletins with inaccurate information as weather conditions were worse than predicted. Mismanagement of flight, poor organization of operations and poor decisions made by the various actors involved in the organization of the flight were considered as contributing factors.

Circumstances:
The airplane arrived in Kazalinsk at 1020LT and 12 passengers embarked. The aircraft was fully booked and ready for departure when the captain accepted, against retribution, that 12 additional passengers (11 adults and one infant) embarked as well. Some 120 kilos of cargo and 120 kilos of additional baggage were also loaded. After takeoff, while climbing to a height of 200 meters, the airplane adopted a high angle of attack when the tail stalled. Out of control, the airplane crashed 65 meters to the left of the main runway. 25 passengers were injured while one child was killed. A day later, two passengers died from their injuries and two other passengers died few days later. The aircraft was destroyed upon impact.
Probable cause:
The decision of the captain to embark 12 additional passengers was criminal and against all published procedures. Neither the copilot nor the Airport Manager complained about this decision. At the time of the accident, the total weight of the aircraft was 6,484 kilos, some 1,234 kilos above the MTOW, taking into consideration the actual flying conditions. Also, the CofG was far aft and well outside the envelope, which caused the airplane to stall from the tail during initial climb. All additional passengers did not have safety belt.
