Investigation Summary
During the Tajikistani Civil War, a non-scheduled flight was chartered to transport women, children, and militants from Khorog to Dushanbe. Although the Yak-40 was configured for only 28 passengers, armed militants controlled the boarding process and forced the crew to accept 81 passengers. The crew attempted the takeoff under the threat of being shot. With the maximum takeoff weight exceeded by approximately 3,000 kg, the aircraft failed to lift off before the end of the runway. It struck an earth embankment, a boulder, and a concrete pillbox before plunging into the Panj River and disintegrating.
Final Conclusions
The accident was caused by a massive exceedance of the aircraft's maximum takeoff weight, mandated by armed militants under duress. The aircraft was physically incapable of achieving flight within the available runway distance due to the 3,000 kg overload and the presence of obstacles in the overrun area.
