This could be overcome by new engines, but no one seems to want to buy or
support a new engine design in the certified world.

There are at least three new designs that have either obtained certification in the
last few years or are in various stages of being certified. Lycoming was involved in
one (a diesel), but I'm not sure they are still involved. I like the looks of the
Honda best myself, but it's a few years from certification. Porsche even made a stab
at it about ten years ago. They're still supporting them. The sales records support
your argument in that few people bought them, though.

On the other hand, Maule was working on adapting the SMA diesel to their aircraft
before the company actually got certification for the engine. Although Cessna and
Piper probably won't move fast, I'm sure that companies like Lancair will start using
other engines if they display particular advantages over existing ones.

In Tennessee, it's evangelism.

This article tries to explain the disaster.

I don't know whether it's wisdom or hogwash.
