A preliminary finding into last month’s Air India plane crash has suggested the aircraft’s fuel control switches were turned off, causing a loss of engine thrust shortly after takeoff.

The London-bound plane had barely left the runway at Ahmedabad airport before it careened back to earth. Everyone on board was killed, except for one passenger.

The AAIB preliminary report on Air India AI 171 plane crash only dwells over the fact and in most cases does not point to the WHY and HOW of the crash, rather looking at WHAT. The rest is part of the investigation which takes longer.
