Investigation Summary
On April 27, 2007, a formation of three Mi-8 transport helicopters and two Mi-24 attack helicopters departed from a helipad east of Gudermes. The mission was to provide air support and reinforcements to pro-Russian Chechen troops who had reportedly ambushed a group of separatists near Shatoy. On board the lead transport were 15 commandos from the GRU Spetsnaz Rostov Oblast Brigade, two high-ranking liaison officers (a Lieutenant Colonel and a Major), and three crew members. As the helicopter attempted to land to disembark the special forces, it touched the ground on a steep hillside. The aircraft lost stability, rolled down the slope, and exploded. The crash occurred at 11:34 local time. The incident represented the largest single-day loss for federal forces in Chechnya in 2007. While initial reports from the scene indicated 17 fatalities, the final confirmed death toll was 20. Although Chechen separatists, led by Dokka Umarov, claimed to have shot down the aircraft, and early Russian official statements blamed rebel fire, the technical commission found no evidence of combat damage sufficient to cause the loss, instead pointing to pilot error during the high-altitude landing.
Final Conclusions
The special commission tasked with investigating the crash determined that the most likely cause was human error. The helicopter reportedly touched the ground, rolled, and tumbled down a hillside before exploding during the disembarkation process. No definitive evidence of a mechanical fault or catastrophic damage from small arms fire was cited in the final determination of the commission.
