There's stuff you can do, but......
There's a list of items that the pilot owner is allowed to do himself, but it's all pretty straightforward stuff (a little more than you would do on the old 50 hour LAMP check), and for anything major you need an engineer signing it off....
Mine is on the MIP template (to which you add necessary ADs and anything advisable) but although it's a 100 hour between inspections officially, I still do 50 hour checks as if it was still on LAMP! There isn't actually any great savings to be made, as engineers still seem to do everything as previously, and they have to check your paperwork too......
