Tomsk - Surgut

The twin engine aircraft departed Tomsk Airport at 1010LT on a flight (callsign IK9007/SP5007) to Surgut, carrying 33 passengers and a crew of four. About an hour and 26 minutes into the flight, the left engine's 'chips in oil' warning light came on. About eight minutes later, a burning smell was noticed in the cockpit and the captain decided to divert to Nizhnevartovsk Airport. During the descent, the left engine caught fire. Its propeller was feathered and the crew decided to divert to Strezhevoy Airport. But as the fire could not be extinguished, the captain eventually attempted an emergency landing in the Ob River. Upon landing, the aircraft broke in two and came to rest in shallow water. Seven passengers were killed while all other occupants were rescued.
