On a test flight from Valikhanovo after an engine repair during crop-spraying operations in the Valikhanovo district (Kokchetau region of Kazakhstan) when one of the propeller blades broke away in flight due to fatigue fracture, causing violent vibration, whereupon the engine mount failed. The aircraft turned to the left and the propeller cut through the spar of the left lower wing, causing the wing box to collapse. Aircraft went out of control and span into a field 2 km SSW of the "Yuzhny" collective farm (at N52°33' E71°36'). Both pilots and the sole passenger (an aircraft mechanic) were killed. The propeller had been fitted only the day before the accident.
Probable cause:
Propeller blade's separated in flight.

Circumstances:
The crew was engaged in several flights between Shalkar and Yuzhnyy, carrying oil field workers. After takeoff from Yuzhnyy, the crew decided to make a stop in Bozoy but there was no passengers to embark so it was decided to continue quickly. Shortly after takeoff, while flying at a relative low height in limited visibility, the single engine airplane struck a radio mast (160 meters high) located near Bozoy. The airplane embedded in the mast at a height of 85 meters. Few debris fell down and all three occupants were ejected and killed.
Probable cause:
It was determined that the crew precipitated the departure from Bozoy without checking weather conditions and flight conditions. The following contributing factors were reported:
- Poor flight planning,
- Marginal weather conditions with low clouds, patches of fog and limited visibility,
- The passenger was illegally on board,
- The crew failed to communicate with ATC,
- Insufficient altitude,
- Wrong decisions.

Circumstances:
Shortly after takeoff from Shyganak, one of the passenger entered the cockpit and sat down with both pilots. After the door was closed, the airplane started unusual manoeuvres. At a height of 150 meters, the crew changed heading to 270° when three minutes after departure, the airplane crashed in a desert area located 2 km west of the village. Four passengers were seriously injured while six other occupants including both pilots were killed. Few hours later, three of the four survivors died from their injuries.
Probable cause:
It was determined that after a poor flight organization, the crew allowed a passenger to enter the cockpit without official permission. In unclear circumstances, the crew initiated unusual manoeuvres and full power was set on the engine that may have partially drowned. The airplane pitched down to 5° then banked right to an angle of 40° and struck the ground at a speed of 210-220 km/h before coming to rest 110 meters further.

The aircraft was destroyed and both pilots were seriously injured. The copilot died from his injuries three days later on July 1st.
Probable cause:
It is believed that the loss of control was the consequence of an intense fatigue that suffered the crew. It was determined they flew more than 13 hours everyday during last eight days from 20 to 28 June.

Circumstances:
The crew departed Avangard Airport at 1352LT bound for the two last legs of the trip, Shchuchinsk and Kokshetau. Due to the deterioration of the weather conditions, it was decided with ATC to fly directly to Kokshetau. At 1418LT, the crew informed ATC about his ETA in Kokshetau at 1448LT when seven minutes later, contact was lost. The wreckage was found the next morning at 0845LT at an altitude of 850 meters on the slope of Mt Sinyukh (947 meters high) located six km west of Burabay. The aircraft was totally destroyed and all 15 occupants have been killed.
Probable cause:
The crew took the decision to continue into adverse weather condition instead of flying back to Avangard or to modify his route. The following contributing factors were reported:
- Lack of ATC assistance,
- Poor weather conditions,
- Poor flight organization.
