What happened
During a flight originating from Sestsha Airbase in Bryansk, a four-engine Antonov AN-12BP was transporting 14 passengers and six crew members. While performing an approach to Tula Airport under conditions of low visibility, the aircraft struck another Antonov AN-12BP operated by the Soviet Air Force. This second aircraft, which carried a crew of six, was conducting a local training maneuver in the vicinity of Tula.
The impact caused both planes to descend rapidly into an open field situated a short distance from the airport. The accident resulted in 27 fatalities, as there were no survivors among the occupants of either aircraft.
Findings
Investigations into the mid-air collision identified several critical factors. A primary contributing factor was the failure of radar equipment, which prevented air traffic controllers from accurately tracking the positions of the two flying vessels. Additionally, the presence of marginal weather conditions and reduced visibility significantly hindered the ability to maintain safe separation between the aircraft.
