Key questions facing Air India crash investigators

As investigators begin examining the crash, aviation experts believe they will pursue multiple lines of inquiry utilising data from the black boxes, equipment, crew performance, ground operations and the jet's maintenance.

Did the plane lose power, if so, why?
Was this a dual engine failure or severe thrust loss on both engines?
Could the problem have originated in contaminated fuel?
Was there foreign object debris - such as a bird hit- during takeoff?
Was there an issue with the electrical systems?
Why were flaps, which (generate lift, retracted, but landing gear extend- ed in its final moments?
How was the recent maintenance record?
Were take-off fuel and weight param- eters in range?
