Interesting...I never thought you ever would go back to Phase 1.  So let me pose
a question. If that is true and  you make a major change like going from a VW to
a Corvair do you have to go back to Phase 1?

I have had my KR back in phase 1 testing several times following an engine 
change, new tail, etc, etc.  Time is set at the descretion of FSDO, but they 
have never assigned me more than 5 hrs.

Yes.  The specifics will be written in your operating limitations.  For 
example, for my 1999 Glastar it says:

"The cognizant FAA office must be notified and their
response received in writing prior to flying this aircraft after
incorporating a major change as defined by FAR section 21.93"

Current guidance can be found in FAA Order 8130.2g.

http://www.faa.gov/documentLibrary/media/Order/8130.2G.pdf

If you have op lims after 1999, the aircraft owner now just has to make
two entries in the logbook - one describing the major change, and after
a minimum of a five hour test flight, one showing that the safety of the
aircraft (FAR 91.319) and the critical airspeeds (Vx, Vy, Vso) have been
reestablished. No need to contact the FSDO.

Note that 8130.2g starts with:

"After incorporating a major change
as described in 14 CFR ? 21.93"

21.93 says, "A ??minor change?? is one that has no appreciable effect on 
the weight, balance, structural strength, reliability, operational 
characteristics, or other characteristics affecting the airworthiness of 
the product. All other changes are ??major changes?? (except as provided 
in paragraph (b) of this section)."

Changing to a different type of engine should be easily shown to be a 
major change.

I let my DAR know, or ask someone at your FSDO.  They will tell you, but I
do believe that an engine change will do that.  In fact, if I remember
correctly, I went back to phase 1 when I changed from the VW to the Corvair
on the BlackBird.

I'm not sure what the duration would be for a completely different 
engine, but I hear "five hours" thrown around a lot for a "major 
change", and 20 wouldn't surprise me.  When I went from my 3100cc back 
to a 2700cc Corvair, I called the FSDO and they said "don't bother us 
about that little change or a propeller change, but if you  change to a 
completely different type of engine, call us back".  I think it depends 
a lot on what's written in your "operating limitations", and probably 
even more on who answers the phone at the FSDO!

 From an FAA website:

  Each aircraft issued an experimental airworthiness certificate has 
operating limitations attached. During flight-testing, specific 
limitations (phase 1) are prescribed for you to show the aircraft is 
capable of safe flight (compliance to 14 CFR section 91.319 "Aircraft 
having experimental certificates - Operating limitations".)  After 
successful flight-testing more liberal (Phase II) operating limitations 
become effective.  Examples of operating limitations for amateur-built 
aircraft are in Order 8130.2, "Airworthiness Certification of Aircraft 
and Related Products".

You are going to get 40 hours for phase 1, and unless I am mistaken, you
never get out of phase 2, unless you go back to phase 1 due to major changes
to the aircraft.



You should perform all the basic tests in phase 1 during the 40 hours that
you will have to fly within the area that you are given by your DAR.



This is standard for most experimental aircraft.

One question I've been wondering is simply how many hours on average were
you guys able to complete Phase 1? Phase 2?

KR> Phase 1 and Phase 2 flight testing

[T. W. Norman]

Good morning,



I have been doing some research on the flight testing for my KR-2. I'm not
planning on getting in the air with the aircraft until the spring, so I
think this winter I'm going to develop the plans for the flight tests.



One question I've been wondering is simply how many hours on average were
you guys able to complete Phase 1? Phase 2?



Thanks,

Trevor
