LJ fair enough, yes I agree the A/C docs will be looked through but that does not imply that FGS engineering will be looked at, as the A/C was only handed over to Ethiopian in December all the docs will already have been scrutinised by Flyertech and Ethopian (+ILFC) prior to handover so therefore it is unlikely there will now be any FGS engineering issues, obviously not being at FGS since July 08 I have no idea what check JP went through prior to redelivery to Ethiopian but the Norm is 'C' check. So this would be the likely starting point (from an engineering issue) of course it would be normal practise to examine all maintenance documents from birth.
