I have done a few dozen PFLs in the PA38 and it glides well enough for the purpose.

Forgetting all the stuff about unapproved maintenance, I’m not an engineer yet I have no worries removing and cleaning spark plugs on the Lycoming in my aircraft (On permit, of course). The main lesson here is the basic one that seems to have been forgotten. On an EFATO land straight ahead – never turn back.
