Subject: | converting an RV to LSA |
The simple answer to your questino is 'NO'.
The long answer is twofold. Once your aircraft has been given a gross weig
ht over 1320 you can't go back. The next answer is that once an aircraft i
s certificated in a class it can't be changed over to LSA. Why?....Because
it does not have to. If the aircraft in question meets the definition of a
n LSA aircraft per FAR 1 then the aircraft may be operated under the LSA ru
les irregardless of the aircracft certification category=2C Experimental=2C
Standard=2C whatever.

Subject: RV-List: converting an RV to LSA
Dear RVers
This might sound ridiculous but does anyone know if it is possible to conve
rt a registered RV6 to fly within the LSA guidelines? I know it might take
mountains of changes but I am just wondering if it is at all possible. So
me of the obstacles to overcome would include addressing the the weight=2C
I think that might be possible by stripping out all the niceties and gettin
g back to only what is basic. Another way to reduce the weight is by doing
what one of the LSA companies do which is to just say that the baggage cap
acity is now only xx instead of what it is actually capable of. The next c
oncern is speed at full power. With the existing O-360 this might be diffi
cult. One LSA company uses a ground adjustable prop to limit the max speed
of their airplane=2C so I am sure that would help. Eliminating the good l
ooking wheel pants could add some drag too. Some props have RPM restriction
s which must be adhered to willingly. Can the operating limitations specif
y a maximum speed of 120 kts or an RPM that limits the speed to 120 kts. S
ome LSAs have a higher RPM for a maximum number of minutes for take-off and
then a reduced RPM thereafter. How could the clean stall speed be reduced
to 52 MPH? Would the lighter weight and maybe some vortex generators acco
mplish that? From what I have read=2C no plane can be flown as an LSA unle
ss it has always been able to fly within the parameters of one=2C so=2C is
it possible to de-register my RV6=2C surrender the data plate and re-regist
er it as a plane that is capable of flying within the LSA parameters.
Maybe I am crazy for wondering about this but I am not interested in buildi
ng another plane =2Cthe market has been too soft for selling at a reasonabl
e price and I don't want to spend $125=2C000 for an LSA. I am sure I am no
t the only one with a medical problem that has wondered this=2C so is this
doable or just a foolish wish.

Dear Mike=2C
I was speaking with the people selling the Paradise LSA from Brazil and
they said that in Brazil they have their plane certified as a four seate
r with a gross weight in excess of 1700 lbs=2E In order to certify it L
SA in the USA they removed the two rear seats and declared the baggage c
apacity to be less=2E Is this something totally different=3F Is it poss
ible to de register the RV and apply all over again=3F
I suppose it is time to moth-ball the RV=2E

Mike,
I know it is not *very* easy, but can't you make some "minor" change
in your airframe, power plant, or prop and then declare that the
aircraft no longer has the ability to carry 1320 + lbs? Then apply
for the "self conducted" 5 hour re-certification.

Again - NO.
However, if you did all that before you ever got the airplane certified then
it may be possible. This is no different than trying to change a fat
ercoupe or fat chief that were to heavy for LSA...or a C-120/140. You
simply can't go backwards with the paperwork, even if you can with the
physical plane. There are a lot of planes that could be "lightened", but
that in itself won't work because the paperwork at one time said your plane
had a higher gross weight.
I think it's pretty clear in my opinion. I would put my efforts into just
building an LSA the first time.
My 2 cents as usual.
Cheers,
Stein

And you could build your RV very light, the way you want it. You could
probably remove the data plate from the engine, put a smaller carb on
it, ...... to derate the engine ..... and have it meet all the LSA
requirements ...... and then fix the problems later after certification
and the phase 1 testing. And you'd end up with the same airplane in the
LSA category. Far more work than you really want, I guess, but still
easier than making the present plane fit the category. Turning in the
airworthiness certificate, making the changes to make the airplane legal
LSA and re-certifying it may work. Stranger things have happened.

I suggest one purchase a new 244cu ft or a 300cu ft.cylinder, or more for c
ascade filling,-then paint or stamp your name on the cylinder then insist
(eccentric request so fake a tic) on getting your marked cylinder back if
your are worried about contamination.

So everyone has a huge concern for gas purity.- Thay
may have been why they decided to go to single-source
filling.- Like I said before though, there are some
situations where they will pull a vacuum on a cylinder
before filling it, to empty it first.- So they may do
this for some medical/aviation O2, hence that may be
why they just want to swap you.- But, if you're
always filling it with pure O2 you have no worries.
Additionally, one thing you should try to do is never
run your bottle completely empty.- Keeping 100psi in
it at all times will ensure that no contamination gets
in.
