As an inexperienced aircraft buyer, you always wanted a way to own an airplane and fly it to build flying time.

As an inexperienced aircraft buyer, you always wanted a way to own an airplane and fly it to build flying time.  The savvy Piper dealer at your local airport has a used but beautifully repainted, ready to fly Piper Tomahawk that they say will pay all of its expenses back if you lease it back to them for their customers to rent.

After paying full price with the same dealer’s financing, you find out that the same dealer also has their own PA-28 aircraft, although a little worse for wear, that they are renting to the public at a lower rental rate.  Winter is coming, the demand is less for aircraft rentals, and numerous aircraft ADs (Airworthiness Directives) suddenly show up in your home mail box demanding your immediate attention for your Tomahawk. Then, during a scheduled flight school demonstration flight with a prospective student, your aircraft suddenly throws a cylinder (and piston) in flight, which ends up requiring a hefty repair bill that you have to pay, since it is your aircraft and you are required to pay all fuel, oil and scheduled Part 61 maintenance items.

Where is this leading?  What legal recourse actions do you have to end this aviation nightmare?  What should have been done in the first place (besides strangling the salesperson?)
