On July 10, 1985, the Tupolev Tu-154 operating the flight was involved in an aviation accident when it crashed due to a high-attitude stall in the Kyzylkum Desert, near the city of Uchkuduk.

There were 191 passengers onboard the flight, which had consisted of 139 adults and 52 children, which met the standard regulations of 92,200 kg (92.2 tonnes).

The aircraft then entered the jet flow zone with a weight of 86,500 kg (86.5 tonnes); the air temperature of the specified flight path was 16.5°C (61.7°F) higher than the standard.

[citation needed] The crew contacted the dispatcher, stating that they were in a flat spin and had no power on the engines.

The Ministry of Civil Aviation had concluded the cause of the accident:[3]The cause of the disaster was the aircraft entering a flat spin at cruising altitude with a high flight mass, influenced by a high non-standard outside air temperature, a small angle of attack margin, and engine thrust.

[citation needed] It is believed that the crew had been exhausted due to the poor resting conditions during the delay at Karshi, which caused the pilots to make inadequate decisions during the ascent and fail to be aware of the situation.
