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 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.
