The single engine airplane departed Kyren Airport in the afternoon with four employees of the company and two pilots. The purpose of the flight was to familiarize them with the area of the planned aviation chemical works for the processing of the silkworm. As the airplane failed to return to Kyren in the evening, SAR operations were initiated, but abandoned few days later as no trace of the aircraft was found. More than a year later, on July 24, 2021, a group of tourist discovered the burnt wreckage near the Baikonur Pass, in a rocky area, at an altitude of 2,780 metres. The airplane was destroyed by a post crash fire and all six occupants were killed.

Probable cause:

The accident with the An-2 RA-71276 aircraft occurred as a result of a collision with a mountain at an altitude of 2,780 metres above sea level perpendicular to the direction of the ridge with its minimum height of 2,960 metres conditions of limited visibility and the closure of mountain tops by clouds.
The following contributing factors were identified:
- The crew took the decision to perform a flight over a mountainous area with predicted closure of the mountains by clouds and unfavorable wind conditions,
- The crew took the decision to return to the landing site through the mountain range along an unexplored and previously unused route,
- Operational fatigue of the crew due to the significant duration of working hours on the day of the accident (more than 12 hours),
- The airplane falling under the influence of descending air currents on the leeward side of a mountain slope.

Aircraft flight hours:

Circumstances:

The crew departed Kyren Airport on a crop spraying mission to treat forests. About 40 minutes into the flight, while flying at a speed of 140 km/h, the crew encountered downdrafts and the airplane lost height. Due to mountainous terrain, the crew made a turn to the right but the airplane continued to descend. The captain attempted an emergency landing when, at a speed of 85 km/h, the aircraft struck trees and crashed in a wooded area located 16 km southeast of Dabady. Both pilots were injured and evacuated to Irkutsk a day later. The aircraft was damaged beyond repair.

Probable cause:

Most likely, the reason for the accident with the An-2 RA-81519 aircraft was the execution by the flight crew along the route in the mountainous terrain to the area of the AHR at an altitude not ensuring its safety, which did not allow crossing the mountain pass, led to the need to perform an emergency landing and damage to the aircraft.
The contributing factors were most likely:
- Non-consideration by the crew of a significant increase of the outside air temperature during the day,
- The crew did not set the altimeter properly,
- Lack of instrument control over the flight altitude,
- Downdraft air currents on the leeward side of the mountain slope;
- Operating fatigue, leading to a weakening of attention and a decrease in level of situational awareness.

Crash of a PZL-Mielec AN-2R in Nizhneudinsk

Circumstances:

The single engine airplane departed Nizhneudinsk Airport on a forest fire survey mission, carrying two observers and two pilots. Shortly after takeoff, while climbing to a height of about 150-170 metres, the engine started to vibrate. The captain attempted an emergency landing when the aircraft crash landed in a marshy field located 4,9 km from the airport, coming to rest upside down. All four occupants escaped uninjured and the aircraft was damaged beyond repair.

Probable cause:

The accident was the consequence of a total engine failure during initial climb for reasons that could not be determined. The fact that the field was waterlogged and did not permit a safe landing was considered as a contributing factor.

Circumstances:

The single engine aircraft departed Yeniseysk in the afternoon on a spraying mission over forest area, carrying two pilots. About 40 minutes into the flight, while completing a third pass at an altitude of about 400 metres, smoke spread in the cockpit. The crew decided to return to Yeniseysk when few minutes later, the engine lost power. Fuel leaked from the engine and spread over the windshield. The crew reduced his altitude to 50 metres and the speed to 85 km/h, preparing for an emergency landing. With the flaps down to 45°, the aircraft collided with trees and crashed in a wooded area located 75 km north of Yeniseysk. Both pilots were slightly injured and the aircraft was damaged beyond repair.

Probable cause:

Loss of engine power due to the failure of the cylinder n°5 caused by a faulty manufacturing.
