I'd guess they're just covering broad bases of what could cause a plane to crash a few seconds after takeoff.Probably me reading more into it than what's there, but given that it suggests more inspections of Engine/Fuel/Hydraulic systems, does that not point to them suspecting Engine failure rather than pilot error?
Could be an interesting PR fight coming up regarding the preliminary report from blackbox data - Air India will want it out quickly if fault appears to lay with Boeing; Boeing will want it out quickly if fault appears to be with pilots/airline, especially given their ongoing issues.
