Re: KR> DAR inspections

[Jeff Scott via KRnet]

Bob,

In the US, a DAR inspection is the only FAA inspection required on an Amateur 
Built Aircraft, and is only performed after the aircraft is completed.  All 
other inspections are typically by an EAA Tech Counselor and are strictly 
voluntary... i.e. not required.  Even the Tech Counselor inspections are only 
recommended 3 or 4 times during construction.  It is highly unlikely that the 
Canadian Government would be willing to backtrack and allow you to use what 
they would consider to be uninspected parts such as the box spars, closed out 
wings, or a closed out fuselage.

Hi All;
I am considering a project in the U.S. that has no documentation whatsoever and 
am wondering about DAR inspections.
I want to import this project into Canada and our inspections require a pre 
cover (before box spars etc,are closed in) .
What I am wondering is if I might find a number or something that shows it was 
done in the U.S .
In Canada each component is stamped or stickered to show it has been done.
The project is fairly complete all spars are closed, wings closed etc.although 
it would still meet 51% requirement here in Canada.
I f I can show the inspections I an import as parts and then continue it.
Any thoughts about this?
Thanks

Approx,. 9 3/4 to 10 inches vertically from bottom of engine pan to bottom of

Hard to measure without removing the lower cowling at this time.

Re: KR> Tailwheel assembly

[Jeff Scott via KRnet]

You can order direct or through your favorite aircraft parts vendor. If your 
spring is mounted at a non-standard angle, they will be happy to make one to 
fit your plane.  Choose between the 4" solid tail wheel or the 6" 
semi-pneumatic tailwheel (hollow inside to make a bit softer).

Re: KR> DAR inspections

[Robert Russell via KRnet]

I am kind of thinking that if I do buy it, it would just be for the parts such 
as 2 Great Plains engines landing gear, canopy, wing attach fittings, cowling,  
controls such as bell cranks etc.
There is enough value there for those items and anything else I could salvage 
would be gravy. i.e like maybe the fuselage but if not just plan to build all 
that from scratch.

Here in the US. It is NOT recommended to buy a project under construction 
without a builders log.  The thing is you have to prove that 51% of the 
airplane by amateurs and without a log there's no way to prove.  From what I've

without a builders log. You're buying nothing but a problem.

KR> disassembly

[Robert Russell via KRnet]

I guess I should have asked also n my previous email if anyone has had to open 
up box spars or remove the stub wings or any other disassembly with good 
results. By that I mean to be able to then re use those parts. 
I am wondering how much of a project can be saved if I have to take it apart at 
all.

Does it not have a steel insert embedded in the end that is about 3/4" 
thick to bolt the plans version of the tailwheel bracket to?  That's how 
the one is on Jim Faughn's plane.  I'll get you a picture of it...

Re: KR> 4-into-1 exhaust system help?

[Chris Gardiner via KRnet]

Mark,
I can send you some dimensions on the GP 4 into 1 pipe as I have one.
The pictures John Bouyea posted show the offset from the front view as well as 
anything I can send.
Suggest you consider the Revmaster stainless 4 into 1 option. I installed it 
last year for peace of mind that it will never rust out . It has about the same 
amount of offset.
I will take a picture of the SS style and measure it today for you.
The only difficulty I had with the Revmaster is that it is slightly different 
at the back and interfered with my intake manifold ( Zenith 1821 carb.)
This may not be an issue for your set up.
Cheers
Chris Gardiner
