" He should have sent you a signed copy of the purchase contract before you signed it. Without reading the actual contract, it would seem that since you signed it already, he can prevent you from selling the airplane because if you did, he can then sign the contract you returned to him and claim you had already sold the airplane to him."
Or........ He can claim that you defrauded him out of his $1000 deposit from the beginning; because you "had sold the aircraft" to someone else " (or intended to ) .
Not a Good situation. The minute he sent back "his" paperwork to you unsigned --- I would have pulled the plug on this deal.
