Dave,

Can we? I don't know if FOI covers that, but the FAA certification
division sure can. And they have the failure reports on file. That's the
point, though. These conversions AREN'T certified. In effect WE are the
certifying entity and as such the responsibility falls on us and we can't
make that decision with glossed over reports of "trouble-free" service.

If the failures happen during development, and they make design changes to
address the failure before they present the engine to the FAA for type
certification, then the FAA may very well not have anything on file. The
FAA makes a very big point about not getting out the microscope until they
are presented a test article that conforms to the type design. The
definition of the type design evolves during the development process as
problems are found and fixed.

I hope I didn't scare you with my shouting. 8-)

Not me, anyway, but I have an honest question: Do major GA engine
manufacturers make data on failures *in development* available to the
public? Can we see test-to-failure data on the new engines Lycoming,
Superior, Mattituck, etc. are putting out for homebuilts? Where?

Seems to me what an auto conversion needs is a 'sugar daddy' to put up
big $$$ to fund develompent and testing testing testing. I'm not holding
my breath.
