Fair enough. Perhaps that question was too broad. Let me rephrase. When you bought your used aircraft, what few things did you check for?
I part own one at the moment and I just rent over the last couple of years neither of which are really satisfactory. Not being in the game that long I haven't really built a feel for things to watch out for, although I've learnt lots following discussions on this forum and others.
So my question was not about any plane specifically, but an attempt to capture that 'feel' if that's possible. For example, an RAAus plane with a couple thousand hours is high but GA world that's quite low. Other things like the recent discussions on batteries and the dangers of one type over another. Or avoiding short coupled tail draggers unless you have good training and hours already. <insert other mechanical/physical things here..can't think of any>
So perhaps rather than say tell us what you've learn over 10,20..50 years, how did you go about inspecting your last aircraft purchase? Not asking for an exhaustive list, just a couple of key pointers.
