Flight Details
The aircraft was dispatched to the Veydelev region for a crop spraying mission. On board were three pilots: one pilot-in-command seated in the left seat, an instructor in the right seat, and a copilot occupying the jumpseat.
Accident Sequence
During the first pass over the area to be treated, the aircraft flew at a speed of 140 km/h and an altitude of 130 metres. The crew then initiated a right turn, during which the aircraft banked to a 90° angle, descended to 60–70 metres, and lost speed to 130 km/h—below the expected range of 155–160 km/h. While facing a hill, the crew increased power to gain altitude, but the aircraft struck the ground while in a landing configuration. The crew reduced engine power and applied brakes. At a speed of 50–60 km/h, the aircraft collided with trees and came to rest in a wooded area.
Injuries and Damage
All three occupants sustained injuries. The aircraft was damaged beyond repair.
Probable Cause
The official investigation determined that the accident was the consequence of a crew error in piloting technique when flying in difficult terrain conditions. This error manifested in a loss of speed and flight altitude, leading to an unintentional landing and collision with ground obstacles. The error was attributed to unstable piloting skills of the pilot-in-command and the instructor's failure to fulfill his duties. It was reported that the pilot-in-command had not flown for approximately five years.
