Narrative:The Ju-52/3m was being ferried from Alma-Ata to Kuibyshev for undergoing state trials with the NII GVF (State Scientific Test Institute for Civil Air Fleet).
While on the leg from Alma-Ata to Semipalatinsk the flight deviated from the prescribed flight path in order to circumvent an area of poor weather. Over high mountains the aircraft was not able to gain sufficient height. The airplane stalled and crashed at an elevation of some 2,700 metres into the steep wall of a gorge near a pass over the khrebet Dzhil-Dhuta mountain range (3,050 metres), 15 km north-west of Kok-Su.
