The Aircraft Accident Investigation Bureau (AAIB) has released a preliminary report on the Air India flight AI-171 crash. The report reveals that the co-pilot was in control of the aircraft when it crashed shortly after departing from Ahmedabad on June 12.

A preliminary report released on Saturday has found that fuel-control switches were cut, but does not explain why.

Fuel control switches for the engines of an Air India flight that crashed last month were moved from the ''run'' to the ''cutoff'' position moments before impact, starving both engines of fuel, a preliminary investigation report said early Saturday.
