Video shows near-vertical crash of Russian plane
In 2001, it was damaged in a landing accident in Brazil that injured no one.
The company insisted that the aircraft was in good condition for the flight.
The carrier has had a good safety record but appears to have run into financial problems recently. Its personnel went on strike in September over back wages, and the Kazan airport authority has gone to arbitration to claim what it said was Tatarstan Airlines' debt for servicing its planes.
Industry experts have blamed some recent Russian crashes on a cost-cutting mentality that neglects safety in the chase for profits. Insufficient pilot training and lax government controls over the industry also have been cited as factors affecting Russian flight safety.
Former Finance Minister Alexei Kudrin said Monday the government should tighten its oversight of carriers and subsidize the upgrading of their fleets to improve safety.
