All 170 passengers and crew onboard were killed.
The investigative committee's final report said the crew failed to follow procedures that would have prevented the plane from stalling, causing it to plummet to the ground.
It said a junior pilot-in-training was at the controls at the time of the accident and that the more experienced captain failed to assist him.
The Tupolev-154 crashed while flying through bad weather, on a flight from the Russian Black Sea resort of Anapa to St. Petersburg.

A BLEAK PICTURE: Below, HRW experts comment on the human rights situations in some of RFE/RL's broadcast countries.
Human Rights Watch's Asia Research Director Sam Zarifi, speaking about Afghanistan:
"The Taliban have been using increasingly brutal tactics such as suicide bombings and attacking soft targets, such as health clinics and schools. The attacks on schools have been particularly vicious. More than 200,000 children who were in school last year have not been able to go to school this year. We've seen over 130 schools attacked. The resulting fear, of course, has caused a huge amount of resentment, especially in southern Afghanistan, because ordinary Afghans feel that President [Hamid] Karzai and his international backers are not able to support them and provide them what they need.
Basic reconstruction and development throughout the south has essentially come to a halt in many areas. The situation is not just bad in the south, however. In the north and in the west of the country, warlords -- many of them ostensibly allied with the government - have also used the threat of the Taliban and the weakness of the international community and President Karzai to re-entrench themselves and so Human Rights Watch has been documenting numerous instances of land grabs, political oppression and rampant human rights abuses by these warlords, many of whom are also involved in the drug trade."
Giorgi Gogia, of Human Rights Watch's Caucasus Office, speaking about Georgia:
"Georgia, in late 2005, announced a reform of its criminal justice system and started a rigorous fight against organized crime, particularly against the power of organized crime bosses. While this move is certainly commendable, this had some negative consequences, particularly overcrowding in prisons and abuse of power by some police or law enforcement structures. Overcrowding is particularly a big problem in Georgian prisons, considering that they are very poorly ventilated, filthy, and prisoners very often receive inadequate nutrition and substantive medical care."
Rachel Denber, deputy director of Human Rights Watch's Europe and Central Asia division, speaking about Kyrgyzstan:
"In September, Human Rights Watch released a report that documented the poor state response to domestic violence and bride kidnapping for forced marriage in Kyrgyzstan. Our main finding, which I think is consonant with the conclusions of Kyrgyz human rights organizations, is that the authorities just allow for impunity for domestic violence and kidnapping for forced marriage."
Rachel Denber, deputy director of Human Rights Watch's Europe and Central Asia division, speaking about Turkmenistan:
"Turkmenistan is one of the world's most repressive and closed countries. The authorities severely suppress all forms of dissent and they absolutely isolate the population from the outside world. The president, who just passed away on December 21, President Saparmurat Niyazov, had declared himself president for life. He presided over a massive and grotesque cult of personality. This year, due to international pressure, the government reduced some harassment of followers of minority religions; they released several people from psychiatric institutions, where they had been forcibly detained as a measure of punishment. And they allowed one dissident to travel abroad. But otherwise, 2006 was as disastrous as every other year for human rights in Turkmenistan."
Rachel Denber, deputy director of Human Rights Watch's Europe and Central Asia division, speaking about Uzbekistan:
"2006 was one of the worst years for human rights in Uzbekistan in the 15 years since Uzbekistan's independence from the Soviet Union. There has still been no justice for the massacre that happened in May 2005 in Andijon, in Uzbekistan, during which government troops fired on mostly unarmed protestors -- no justice for that whatsoever. And the Uzbek government has continuously rejected all efforts to have an international, independent investigation of the massacre. The government crackdown on human rights defenders, independent journalists, and political activists, is the fiercest we have ever seen in Uzbekistan, since independence."
