I'm modifying the situation a bit to protect the innocent, but here's the general scenario: Plane purchased without a pre-buy inspection by an independent A&P Buyer trusted seller (a reputable flight school) to know if the plane was airworthy Seller performed an annual inspection before the sale and signed it off as airworthy A few months later, the buyer realizes that two AD's are not complied with For one of the AD's, an initial inspection was done, but the AD specifies that a fix be implemented within 100 hours and continuing inspections done every 25 hours until the fix is completed - factory will cover the expense of the fix if done within a year (that was 5 years and 1000 hours ago). No fix was made, and no further inspections were ever logged The school rented out this airplane for instruction, while unairworthy, for almost 5 years. Obviously, the buyer screwed up here, but that's not the point. What's done is done. I'm not privy to any contract information, let's assume it was a "as is" contract. The question is how would you deal with the situation? Would you expect the seller to resolve the issues? Would you talk to the FAA or resolve it quietly? I jokingly recommended that he call the seller and tell them he's bringing it in for repairs after he calls the FSDO for a ferry permit (indirectly ratting out the school) and let them decide if they want to do things differently.
