Sir,

First off, there's no need to reply to this email.  I can see how
busy you are, answering pertinent questions.  I'm just a newbie
checking in.  I am an as-yet non-pilot who is fixing to buy a PA-22
(or maybe -20, the tail dragger version), minus the engine, and plan
on putting a rotary into it.  Naturally I've been investigating both
the engine, and the plane. Thank you for the work you put into your
website and answering people's questions.

Sincerely,

Evan Hales Haines, AK

I need to warn you that the FAA frowns on putting a non-certified
engine in  a certified aircraft. Also there is the question of taking
flying lessons and getting a PP in an experimental aircraft.

"Legally, yes -- you can take instruction and the PP practical test
in your own Experimental with no problem. He'll just have to make
sure it meets all the requirements to take a PP checkride (comm
radio, electronic nav system (VOR or GPS), dual controls, sufficient
flight instruments for the basic instrument portion, etc)."

"Practically, there are potential issues. Not all CFI's are
comfortable getting in an amateur-built airplane unless they know who
 built it or have other assurances that it is safe to fly. In
addition, RV's are slick planes, and you'll want a CFI with either RV
or Grumman AA-1 Yankee experience (the RV kit mfr recommends AA-1's
for fam training prior to getting in a single-seat RV). Finally, he
may have to shop for a DPE willing to do the test in an amateur-built
plane."

Assuming you can find a willing instructor the best approach is to
shop for a an uncompleted or complete experimental high wing tail
dragger on barn stormers or trade-a-plane. If it is complete sell the
aircraft certified engine. It might pay for the plane.

IMHO this will save you some time and money in the long run.

Paul and friends, while it's not too difficult to find an instructor,
even for primary instruction, in your experimental *amateur-built*
aircraft, a Piper with a different engine cannot be licensed that way.
If you wanted to put a rotary engine in a Piper it would be licensed
experimental *R&D* and you cannot use such an aircraft for flight
training. Mr. Hales would do well to discuss his plan with the FAA FSDO
who would have to approve it -- not likely to happen, even in Alaska.
The relevant question would be "would you approve flight instruction as
part of the operating limitations for an experimental-R&D airworthiness
certificate?"
