    They have had to have used a fairly large list of parts. Ask them for that list. Then they had to have taken a lot of measurements, ask them to see the pages of written measurements. Ask where they got their overhaul kit and then call and see if that was true. Rotax Service centers are usually the only ones capable of doing full engine overhauls. Look at the logbook label. It should be specific as to what they did. If it is just a 3 line label, no parts list and no measurements then I'd be doubtful to. Find out the person's name that supposedly did the overhaul and have a Rotax Service center person call him and ask him questions. I have done this for a few companies where an A&P was supposed to have done things like an annual and then found out they did a garbage job and failed to do 2/3 the work and said it was an annual to just get the money. These people all got their money back and some sales were lost. There are experts out there you can use.
    This is also why good documentation is important to both parties.
