I would suggest yes, up to the point of the crash, at which point the responsibility devolves around the insured.
Isn't that what I said in post 2?
Pretty much, Who would know, unless there is an inquiry & why would there be one of those unless there was an incident to warrant such an inquiry?
What about a situation where the owner has insured the a/c but is not qualified to fly it (taildragger frinstance) so gets his mate to ferry the a/c home while he comes too so as to "have a go", but doesn't tell the insurance co cos it is Sunday. They land safely
