Yes, fully understand the rationale. But did you have an independant engineering survey, and attendant written report of the aircraft before you signed to purchase? Surely you did; and that gives an edge to any argument for negligence you may choose to proffer against either or both the seller and engineer. If not then it is a busted flush I fear. Would you buy a 2nd hand car from someone (as a private sale as I suspect this is) without an inspection, just because it has a new MOT? No, I thought not. - VFR
