A friend of a friend is interested in putting a 13B in a
Super
Pacer. A
Super Pacer is a stretched Piper Pacer (longer fuse,
bigger wing).
Has anyone done one in the past?
Paul, would you be willing to do a FWF 3D for him? If so,
what
info
would you need?

I had considered doing this too.. I think it's a good fit. I
know of a
couple of Pacer's with STC'd 180hp Lycomings (in an
essentially stock
airframe). They make good performers. With a stretched wing
and fuse
you end up with a nice utility airplane. Pacer airframes are
still
pretty cheap too.
Other airframes that are a good deal and a pretty good match:
Cherokee 140
Stinson 108x
Cessna 175
The Pacer is probably the easiest to accomplish this kind of
thing on
since they are tube and fabric and relatively easily
modified. Plus,
several of them have already moved to Experimental (amateur
built) -
putting on Ford V6's. I don't see that a Stinson would be any
harder
though. And I think there are several things about Stinsons that
are nicer.
Matt-
Check with your local FSDO on the rules.

It's relatively easy to mod a tube-fabric airplane enough to qualify for
amateur built.. Putting what are essentially different wings on it, and
stretching the fuse, plus all of the replumbing/recovering work, plus
completely changing the type of engine makes it pretty easy to argue
that you built more than 51% of the plane yourself. It's a big project
compared to building something like a Lancair Legacy kit, or even an
RV. Any airplane is just a collection of parts.

Hi Matt, This is a very popular MISCONCEPTION. Go to your local FSDO
and ask to see the checklist, I did. The FAA uses only that list, and it
is interesting and informative. This item by item " you built it / you
did not build it " list is also used by DAR's when they are employed to
do the A/W inspection. Sometimes projects slip thru an examiner---look
back a few months at Sport Aviation and you will find a SEABEE with a
Corvette engine in it. The article glows with this misconception, now
look more recently and you will find an obscure article about the same
plane and the investigation that has started to determine how the A/W
certificate of "experimental-amateur built" was ever issued in the first
place. "Amateur built" is only ONE of several Experimental
sub-catagories and is GOLDEN for all who abide by the actual "I built
51%" rule. Please DONOT encourage people to take advantage of this good
rule. Simply moving production parts is not "building" the part. Yes,
you can reuse a large part like a wing, or an engine, or a rudder, or
control assembly, but you get NO checklist credit toward the sacred 51%
so you would have to make up the difference elsewhere. It's all on the
checklist for anyone to read for the asking. When the dust settles on
the SEABEE it will probably continue to fly, but the owner likely will
have to live with the MUCH stricter restrictions provided in the other
sub-catagories of the Experimental
Class. Dave M
Dave,
I too wondered about that Seabee. Not that I think there's anything
wrong with what he got away with, but I do think he got away with
something there. In that case, there were mods to the parts that they
fabricated - my recollection is that they basically rebuilt (as in
deriveted and mostly reskinned) most of the airframe, but overall, the
parts were still Seabee in dimension and construction.
In the case of a Pacer, if you cut up the fuse to extend it, you can
claim that as work done. I'm not saying you can claim that you built
the whole fuse. If you build a set of wings from a Supercub kit (or
PA14 or whatever), that's a no-brainer. Building a motormount, building
landing gear (you probably have to go longer than stock Pacer gear for
prop clearance), fuel tanks, instrument panel, covering, painting,
plumbing, upholstery, cowling, etc. all counts. Each of these items
contribute to a finished airplane. Your DAR (nor the FSDO) might not
initially agree, but if you demonstrate that you did all of this work,
it counts. You'll want docs.
I'm not sure what you mean about "take advantage of this good rule." In
my opinion, if people don't take advantage of the rule, the ability to
do good projects will absolutely be lost. The people need to continue
to push back against moronic regulation. This is not a case of "Shhhh!
We need to do this quietly or else they'll make it illegal."
I believe there's nothing sacrosanct about scratch building... Or even
original kit-building.
