The republic is one of the wealthier regions of Russia because of its large deposits of oil. It is also is a major manufacturing center, producing trucks, helicopters and planes. About half of the people who live in the republic are ethnic Tatars, most of whom are Muslims. A spokesman for the Russian Emergencies Ministry, Irina Rossius, said there were 44 passengers and six crew members aboard and all had been killed.

Ambulance workers rushed to the airport to help, but found no survivors among the wreckage. Early reports blamed pilot error or a technical problem, but few details were available on the circumstances of the tragedy. President Vladimir Putin has demanded a full investigation into the crash. A journalist who said she had flown on the same aircraft from Kazan to Moscow's Domodedovo airport earlier in the day told Channel One state television that the landing in Moscow had been frightening because of a strong vibration during the final minutes of the flight.

We were blown in different directions, the plane was tossed around. The man sitting next to me was white as a sheet. Russia has seen a string of deadly crashes in recent years. Some have been blamed on the use of aging aircraft, but industry experts point to a number of other problems, including poor crew training, crumbling airports, lax government controls and widespread neglect of safety in the pursuit of profits. The last fatal airliner crash was in December, when a Russian-made Tupolev belonging to Red Wings airline careered off the runway at Moscow's Vnukovo airport, rolled across a snowy field and slammed into the slope of a nearby highway, breaking into pieces and catching fire. Investigators say equipment failure caused the crash, which killed five people. A 2011 crash in Yaroslavl that killed 44 people including a professional hockey team was blamed on pilot error. And Russian investigators found that the pilots in two crashes that killed 10 and 47 people in recent years were intoxicated.
