Boeing (BA) does not initially appear to be at fault in the deadly crash last month of an Air India 787 Dreamliner, The Wall Street Journal reported late Thursday, citing people familiar with the early assessments of US officials.

The probe is focusing on the actions of the pilots, with preliminary findings suggesting that switches controlling the flow of jet fuel to the plane's two engines were turned off, leading to an apparent loss of thrust shortly after takeoff, the report said.

It is still unclear to investigators why the switches were turned off, according to the report.

India's Aircraft Accident Investigation Bureau, which is leading the investigation with the support of the US National Transportation Safety Board, is expected to issue a preliminary report as soon as Friday, the WSJ said.

The Aircraft Accident Investigation Bureau and Boeing did not immediately reply to MT Newswires' requests for comment.
