This is a HOT topic, as we will see.
If the aircraft has already flown, and is registered, then this presents a dilemma to the original builder: They will ALWAYS be legally responsible for this aircraft, regardless of selling it as components or as a whole.
Check with EAA, They have some documentation available that may be acceptable for the seller and buyer regarding the liability of the aircraft.
Product liability lawsuits generally pit a large corporation with megabucks, against a little old lady who has lost everything. Right or wrong, who do you think the jury will award to?? This type of legal action is rarely found in our income bracket.
Going WAY OUT to the far extreme, if I was in the Megabucks bracket, I would have the aircraft destroyed rather than sell or give it to a musuem. If it doesn't exist, there is no liability.
SIDE NOTE:
In order to license the aircraft in the "Amateur Built" class, you must present evidence that it was "Built by amateurs", i.e. photos, building logs, etc. If the original builder is willing to supply you with these documents, then you are "good to go".
If he's willing to provide these documents to you, then he obviously is accepting responsibility for building the plane, so why not sell you a "FLYING" plane, vs "PARTS"
ALSO, If the sellor wants to sell parts, then the purchase price should be for parts, not a flying plane.
