Fuel cut-off to engines after take-off caused Ahmedabad plane crash: AIIB prelim inquiry
The Aircraft Accidents Investigation Bureau made public its findings on Saturday morning. The lift-off happened at 1.37 pm from Runway 23 and the aircraft air/ground sensors transitioned to air mode consistent with lift-off, it said.
"The aircraft achieved the maximum recorded airspeed of 180 Knots at 8.08.42 UTC (1.38 pm IST) and immediately thereafter, the Engine 1 and Engine 2 fuel cutoff switches transitioned from RUN to CUTOFF position one after another with a time gap of 01 sec. The Engine N1 and N2 began to decrease from their take-off values as the fuel supply to the engines was cut off," it said.
The fuel cut-off appears to have taken the pilots too by surprise. "In the cockpit voice recording, one of the pilots is heard asking the other why did he cutoff. The other pilot responded that he did not do so," the report states.

US regulator: Quite sure no issue with AI 171 fuel switch
Suggesting that the fuel control switches on the doomed AI 171 were manually moved, the new head of the US Federal Aviation Administration (FAA) has said the crash was unlikely to have been caused by a mechanical issue with the plane or inadvertent movement of the aircraft's fuel control switches. "We can say with a high level of confidence it doesn't appear to be a mechanical issue with the Boeing fuel control unit. We feel very comfortable that this isn't an issue with inadvertent manipulation of fuel control," agencies quoted FAA administrator Bryan Bedford as saying. Indian authorities, who are investigating the crash and have requested patience for the final report before drawing conclusions, did not comment on the claim. The doomed plane's fuel supply to engines had been cut off, causing it to crash. It is not known what caused the fuel switches' position to change.
