An engine change cannot be 'replaced iaw xx-xx-xx/401 function satis' somewhere there must be staged breakdown of each task.
Sure it can, normally there is a maintenance manual that describes the procedure and provides the necessary ops checks. Sorry I sort have overshot the 145 part, this would be in your manufacturer supplied heavy maintenance package, for instance boeing would supply a engine R&R job task card starting with pulling and tagging breakers and finishing with an engine run, it would mimic the AMM but allow for tasks to be accounted for in order .
