And another good reason may be the appalling (from what I have seen) apparent indifference to providing decent after sales service by Diamond and Thielert and also the poor standard of maintenance provided by at least one approved facility. The DA40TDi which I usually fly has now been grounded for months because they sent the wrong engine for it (it had been ordered in plenty of time) and now I've been told that there isn't a single engine available in the whole of Europe. I like flying the DA40 but being told that it is going to be grounded for the foreseeable future doesn't endear me to either Diamond or Thielert. How can they get such an important matter so wrong?
PS: It isn't my DA40TDi - just the one I fly and I am getting more and more fed up with the situation.
