Sukhoi superjet crash: The new Russian aircraft made a belly landing during a flight to test its landing gear system. The Sukhoi superjet 100 is a medium-range $35 million aircraft.
The Superjet program hit uncertainty May 2012 after one of its planes crashed in Indonesia during a promotional flight, in which 45 people were killed.
That investigation concluded that the crash was caused by pilot error, not a defect in the aircraft, AvWeb.com reported.
"The crew ignored repeated warnings from the aircraft's systems of the impending terrain conflicts because they thought the alerts were the result of a database problem. In fact, it appears the crew never knew what they hit since they turned off the terrain avoidance functions just before the aircraft, on a demo flight with potential customers, hit Mt. Salak. According to The Associated Press, cockpit voice recordings show the captain of the aircraft was chatting with a potential customer as the aircraft hit the mountain."
