"The families we are representing are troubled and concerned by this preliminary report as it raises very serious questions against Boeing and Air India," said James Healy-Pratt, Aviation Partner at Keystone Law. "There is a documented history of faulty fuel cutoff switches, which clearly created an unsafe condition. "The families will be seeking to obtain answers from Boeing through action in the US courts and will continue discussions with Air India in London, England. "The families also note that the fuel cutoff switches transitioned from 'run' to 'cutoff' sequentially just three seconds after lift-off, with one pilot asking the other why he cutoff - and receiving a response that he did not do so. "The UK AAIB has 'expert' status in the Indian safety investigation.
