On board were 1,200 kg (2,600 lb) of mail and 35 kilograms of personal luggage, along with four passengers seated in the cabin.

When investigating the causes of the disaster the commission found that despite the IL-76's position it still would have left wake turbulence.

The wind was only 1 mph, leading to the conclusion that the behavior of the Yak-40 can be explained only by hitting the wake turbulence of a much heavier Il-76 taking off from the same runway in just 75 seconds before the Yak-40.

Tashkent Airport had a minimum takeoff interval of only one minute, regardless of aircraft type, leading to the relatively small Yak-40 quickly losing control and crashing upon encountering the wake vortex.
