John,

You gotta wonder why people hash this over and over and never get it.

The Regs are the Regs.  Its that simple. Don't be confused by folks reading 
their interpretation when its in complete disagreement with the FAR's and 
your Operating Limitation.

heres an example of BS from Steve's email.

 >>If you change propellers, you must notify the FAA (not by a 337) of your 
change.

This blanket statement about all homebuilts is complete hogwash.  Your 
Operating Limitations says what you should do for Major Changes.  There are 
not little Major changes and huge Major changes and you do this for this and 
that for that..  There are just major changes.  Changing to a new propeller 
is a major change, thats all.  Folow your Operating Limitations on how to 
handle major changes.

There is nothing in your OL, or mine  that specifies whether your engine is 
certified. By definition, if you read the FAR's  the moment you install your 
engine into your Velocity it is Un-Certified. Its on an uncertified mount, 
it has uncertified parts installed on it.  a certified engine can only be 
installed in an airframe that is certified for it. Your airframe is not so 
it becomes uncertified before you ever start it. To return it to certified 
status an IA must enter that process into the logs after it has been removed 
from the experimental airplane. That process could entail anything from a 
complete rebuild to a pencil whip.

I've heard the data plate nonsense over and over.   That data plate has 
nothing whatsoever to do with the certification status of your engine. Your 
logs do.  The engine logs tell the whole story.  Don't be foolish and rip 
the data plate off, you don't need to and its a good reference for doing 
engine work on the plane.
