Circumstances:
A fire erupted in a rear compartment while the aircraft was taxiing at Surgut airport, Khantia-Mansia okrug. Crew stopped the aircraft and started the evacuation. Three passengers died as the aircraft was totally destroyed by fire. Outside temperature was -29° C.
Probable cause:
A short circuit emerged while the aircraft generators were connected to the aircraft's electrical system after start-up of the engines, via an APU. The short circuit caused a strong fire in the generators compartment in the tail which spread rapidly through the fuselage. The cause of the fire was an electrical arc produced by electrical currents exceeding ten to twenty times the nominal loads when two generators not synchronized with each other were brought online but got connected together instead of being connected to parallel busses.
