Agilekhan, I would suggest that your above suggestion may be bordering on shaky legal grounds for anyone to comment definitively. I would suggest that based on experience, that crash investigators would investigate aircraft primary controls as pretty much their first port of call, before the wreckage is relocated where other components such as engine are further inspected to determine if it was delivering power at the point of impact etc.

Any further news on this accident or Coroner's Inquiry.
