What happened
During a scheduled night training operation in Russia, an aircraft was performing its final approach when it descended beneath the established glide path. During this descent, the plane made contact with overhead power cables, which subsequently led to a crash and an intense post-impact fire.
There were six fatalities among the crew members on board at the time of the accident. No other individuals were reported injured in the event.
Findings
Investigations into the crash identified a significant error regarding instrument calibration. The primary factor contributing to the descent below the safe glide path was an incorrect altimeter setting. Specifically, there was a discrepancy of 100 meters between the actual altitude and the altitude indicated on the flight instruments.
