Grounded - Where to get rid of the Building Materials?

OK, the new skinny from the Medical People at CAMI:

I sent them the details and they stated:
********
Dear Mr. Scholl - if piloting a glider or balloon does not require an
FAA
airman medical certificate, then you would be legal to do so. However,
I
would strongly recommend you discuss with your attending physician the
advisability of doing so given your medical conditions and safety
considerations.

Unfortunately, in light of your having received a formal denial from
the
FAA, you are not eligible to operate Light Sport Aircraft.

My doc already suggested I go that route. So Dr. Kowalsky need not be
too concerned.

So, I am going to check it out further. I would not mind a sailplane
rating. And if the aircraft is rated as a sailplane and self launching,
then I can get those endorsements as well. The "motor glider" can not
weigh more than 1836 pounds and can not have a loading of more than .62
lbs, that is weight to span squared.

Now to research what aircraft are rated as sailplane, self launching
and has all that. But I would be just as happy unpowered. Flying is
Flying, whether powered or unpowered.

Or you could restore one of the 1960s-'70s classic Schreder homebuilt
designs.

Keeping in mind than an _ultralight_ glider is restricted to less than
155lbs,
with no other restrictions:

What regulatory differences, if any, would a homebuilder encounter
when building a sailplane or motorglider in stead of an experimental
airplane?

Does the 51% rule still apply? ( I would guess so.) Would one be
able to get an airworthiness cert for a prototype or one-off design,
as one would for an airplane?

Yep, and yep.

There are essentially no "regulatory" differences, but there
are some applicable FAA Orders that control what FAA
inspectors will approve. For an unpowered sailplane, they
leave you pretty much free to build anything. However, if
it has an engine, you'll encounter problems calling it a
motorglider if it's got more than two seats or is above a
certain wingloading (which I don't have at my fingertips).
I suspect they don't want you bypassing the medical rules by
labeling it a motorglider.

Todd,

If my memory serves me correctly it is not a wing-loading limitation. It is
a number that is computed by dividing the gross weight by wing-span squared.
I wonder where the FAA came up with that calculation and its' aero-dynamics
significance?

However, if you check the FAA database you will find there are Windrose
gliders kits that have been registered as "gliders" and others registered as
"airplanes." In such cases a pilot your qualifications must match the
airworthiness certificate.

What 51% rule?

Think about that before answering.

Hi Gang:

Thanks for all the encouragement. I am going to go for the
sailplane/ultralight sailplane fun.

All the metal for the Cassutt/Renegade is on the Barnstormer's
website. There are 2 other ads, one for a set of CASSUTT plans and one
for the plans for a Texas Parasol. The Renegade plans stay with me
cause my wife bought em as a Birthday Present loooong ago 1981.

The GOAT3 Armchair is intriguing, but I think I will just rent the
time. Building is a long way off what with school and all now. So a
2-32 may be the only avenue right now.

I am moving over to the rec.aviation.sailplanes newsgroup for further
fun. See ya'll later!

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
A “powered glider” has specific Type Certification Criteria.
In FAA Advisory Circular 21.17-2A, these criteria are listed:
The maximum WEIGHT does not exceed 1874 pounds (850 kilograms).
The maximum SPAN LOADING (weight to wing span squared) does not exceed 0.62
pounds per square foot (3.0 kg / square meter).
The number of occupants does not exceed two.

I had previously clipped this.

I'm quite sure they don't. The only homebuilt unpowered gliders
I've run accross have been ultralight gliders.

the FAA "Powered glider" criteria a

not over 1874 pounds.
not more than two occupants
Span Loading not more than 0.82 psi

Span Loading is the weight divided by the wingspan squared.

Sorry! That was a typo. Should have been:

Span Loading not more than 0.62 psf
