Marc,

Perhaps we could have the SSA government liaison (or SRA dude) ask all
these questions directly to the FAA. Specifically:

Can a private pilot glider install his own ELT in his own experimental
glider and sign it off?
Does a TC'd glider need a 337 form completed and approved (major
alteration)?
Does a glider with an ELT installed have to meet all (or some) of the
requirements of 91.207?

With an official FAA answer to these questions, and perhaps some more I
didn't think of, we can avoid uncertainty over what rules apply and how
they apply, etc.

I think it is fairly clear that for a glider with an experimental
certificate, you can pretty much install an ELT any way you want, and
likely get away with signing it off yourself (as a non-A&P). I think it
is also fairly clear that an ELT installation in a type certified glider
will require at least an A&P (and possibly IA) sign off, but probably
does not require a 337. The question in my mind, however, is whether
the typical A&P (or IA) would be willing to sign off an ELT installation
in a certified glider, that makes use of uncertified components (like a
rubber ducky). Any A&Ps out there willing to comment?
