Probably a bit late now, but you should know WHY the a/c is being tested,ie is it just a Cof A renewal,or has it been spread all over the Hangar and now reassembled in an eye-catching manner,ignoring the box of `left-overs...?
If the former,it may be fairly straight forward; if the latter,, beware!!
If there has been any recent maintenance,read up what `snags`/gripes/frequent`things` have been written-up,and rectification has been carried out to clear them.Was a pre-maintenance airtest carried out before maintenance, as many `snags` possibly been `carried` but not written-up..Above all,do not be tempted to sign it off,unless you are absolutely positive about it`s serviceability,as it is your integrity in the end...
