From the Wikipedia article
The collision over Tavda was an aviation accident that occurred on Saturday 7 May 1977, when two Aeroflot An-2 aircraft collided in the sky in the area of Tavda airport, killing 29 people.
Investigation and cause
Causes
According to the commission's findings, the crash was caused by unsatisfactory support of flights on local air routes in the Tyumen and Ural civil aviation directorates and the absence of the Tavda airport air traffic controller from his workstation, as well as the crews' sudden entry into difficult weather conditions that hampered visual flight. On the question of which of the causes (the controller's absence from his workstation or the difficult weather conditions) was the main one and which was contributory, the members of the commission were divided.
