KAZAN, November 18, 5:41 /ITAR-TASS/. Apart from pilot errors or poor weather conditions, the Boeing airliner's crash in Kazan could be caused by a subquality fuel, Marat Zaripov, deputy head of the SKR Investigation Department for Tatarstan, said here on Monday.
"A subquality fuel is being also considered as one of avenues of inquiry. At present, an instruction has been issued to sample fuel which the airliner was primed with back in Moscow. The questioning of the air traffic controllers who were monitoring the Boeing airliner for landing is already under way," Zaripov said.
According to initial questionings, a direct cause of the crash could be the airliner wing's graze of the ground during a second landing approach, because the ailiner failed to climb high enough and pick up speed. The Boeing airliner fell 150 metres away from the runway. Zaripov said the fragments of the airliner are scattered over an area of 500 by 500 metres. The Investigation Department official said that the airliner, which has been operated by the "Tatarstan" air company since 2008, already had troubles last year.
Work in now under way at the airport to identify the crash victims.
