In that case, would you buy a 20 year old 'private' aircraft with no airframe, engine or prop logbooks?
I can answer that. Only a fool would how ever you can but you have to have every thing O/H and as say it was a rare aircraft then a full restro
.
I rejected a mitly million $ aircraft sale because the prop S# weren't the same as the log books. If we had of brought it back to Aust we would have had to install new props.
