Aeroflot Flight 6274 was an aviation accident that happened on 17 November 1975 in the vicinity of the town of Gali (Abkhazian ASSR Georgian SSR USSR) with an An-24RV, resulting in 38 fatalities.
At 21:23 (20:23 MSK), with 33 passengers on board, the An-24 took off from Tbilisi Airport and after gaining altitude, reached a cruising level of 6,000 meters.
The crew mistakenly believed they had passed the Gali NDB, which they reported to the controller, while in reality, they were still 8–10 kilometers away from it.
Upon hearing the report of passing the traverse of Gali, he allowed descent to 1,200 meters on the course to the outer marker.
[1] The primary cause was the violation of ATC rules by the dispatching personnel and the crew's error in determining the aircraft's location during descent in the mountains.
