The 2007 Shatoy Mi-8 crash occurred on April 27, 2007, when a Russian Armed Forces Mil Mi-8 helicopter carrying special forces troops and officers crashed in mountainous terrain in southern Chechnya, killing all 20 people on board.

The incident is the largest officially acknowledged loss of life for federal troops in Chechnya in 2007 and the worst Russian military aircraft disaster since August 2002, when an enormous Mil Mi-26 transport helicopter packed with troops crashed into a minefield after being hit by a missile, killing 127 soldiers.

Russian officials initially claimed the helicopter was downed by small arms fire from Chechen separatists.

[citation needed] A special commission tasked with investigating the crash eventually determined that the most likely cause was human error.

At the same the separatists, reportedly led by Dokka Umarov and Ramzan Saluyev, claimed to have killed 30-50 soldiers on the ground and 20-30 airborne soldiers, compared to their own claimed losses of two fighters killed[2] and several wounded.
