What happened
The incident involved an aircraft operating a scheduled service for the Commissariat for Communications. The flight originated in Krakow with a planned intermediate stop in Minsk before proceeding to Moscow. During the leg between Krakow and Minsk, the pilot encountered deteriorating weather conditions. As a result of these conditions, the crew deviated from the prescribed flight path.
While flying at an estimated altitude of 250 meters, the aircraft collided with the slope of Mt Łysica, which has an elevation of 611 meters. The impact site was located approximately 20 kilometers east of Kielce. The crash resulted in eleven fatalities and two serious injuries among the occupants.
Findings
The official investigation concluded that the accident was caused by a critical error in judgment by the crew. The team continued flying into cloud cover without accurately determining their position or knowing the minimum safe altitude required for that specific area.
