Can experimentally licensed aircraft (like my glider) legally install C91
units? I'm not clear on that, but there are plenty of places selling
EBC-102a ELTs, so somebody must be able to use them.

I re-read the rule and since ELT's are not required for gliders (only
airplanes as previously discussed here ad infinitum), I will change my
opinion to say that none of the other requirements of the rule applies to
gliders. I say this because the sentence that states no new installations
may use c91 ELT's says "those required by paragraph (a) - and the ELT is not
required by paragraph (a) for gliders, so I could argue that none of the FAR
requirements are applicable to a non-airplane.

But this view may not be shared by all FSDO's or IA's should you choose to
make a new installation in your glider certificated in any category. I would
also infer that the annual test and logbook entry would not be required, but
I may be out on a limb here tilting a windmill or something like that.

I'd certainly like to stick with my current C91 unit until the new,
improved ELTs are cheaper!

Amen - the FAA would allow you to do that - if they required an ELT in your
aircraft.

Don't they use their own rules, not the SSA rules? I'm assuming you mean
the 1-26 Nationals. Or did you mean the Sports Class Nationals?

The 1-26 Nationals are an SSA sanctioned contest, right? I'll need an SSA
membership to fly in the contest, so I believe it qualifies under the
proposed rule as an "SSA Competition". If not, I'd be interested to hear
that from someone with the real scoop.
