We are all in a heap of trouble if I am! : ) No, there are FAR more
experienced than me in this group...I'm just one of the mouthy ones,
and I can't even take credit for that...they know who they are. : )
The static port has a specific location spelled out in the build
instructions. The original Kitfox kit builders did a lot of testing,
I'm told, to determine an area that was neutral to the airstream, and
thus a good location for the static port which should be
"static"...that is, "standing still, having no motion, quiescent." I
think it should be used as suggested. I also made another location,
directly across the fuse from the originally suggested location, to
avoid any discrepancies in airspeed when slipping the aircraft. I
hope yours is on the side of the fuselage, and not "on the back" as
you describe it. Maybe somebody has their builders instructions
closer than mine, and can answer this positioning question for you.
Mine's at the hangar, where I'm going pretty soon to make some marks
in the new snow. I'll look it up while there.

After I wrote the word "quiescent" I knew it was time to head for the
hangar and blow out the cobwebs...quiescent? Where in the world did
that come from? : ) ( I had to look up "static" and came upon
it...anybody that knows me knows damn well that I don't know that word.)

inches forward of the grab handle on the back of the fusalage. I
will leave it there, but is it necessary or more accurate located
back there. I think it was hooked up to the altimiter.

Lynn, THE STATIC PORT WAS ON THE SIDE OF THE FUSALAGE JUST IN FRONT OF THE GRAB HANDLE. Looks like I hit the caps lock. Did you join the 2 ports, right side and left side with a tee? Pat

I’m in Newfoundland, Canada... As close as you can get to Europe on this continent without doing a lot of swimming. J

I’m going to hold on to the 582 until I get the 912 flying then it’s up for sale, lock stock and barrel.

What model Kitfox is your mount made to fit? That’s the big part I need now. My bolt pattern should be the same as the model II.

Noel, Sorry, no, I do not have the 912 exhaust. I got this plane without the engine. I have the complete 912 engine mount and the firewall grommet door, however. What are you doing with your 582 firewall forward? Where are you located? Pat

I’m going the other way installing a 912 where a 582 now lives. I’m considering moving my header tank, almost 14 lb full, behind the seat. Then putting the oil tank where the header is now, behind the instrument panel. I have to see if it will be easily removable form that location for cleaning. BTW you don’t happen to have an exhaust??

Then you can move the battery forward if needed and you will be able to know how far. It will probably be easier to remove the existing cables at that time than to reinstall them if you need the CG to move back.

Noel, there is a 912s exhaust on Barnstomers. I just saw it a couple days ago. Search "Kitfox" and on page three you should run across it. It seems a little pricey, but I don't know what they go for.

Yes I did, Pat. That was one of the few things that my tech advisor
caught me on...I didn't have a support for the "teed" junction, and I
had to get in there from an inspection hole in the bottom of the
fuse, and install one...what a bear! The tubing is so stiff that it
would likely hold itself in place, but he insisted on it. Perhaps
vibration over time could break the tubes, what do I know?
I couldn't find the drawing of the exact placement in my manual, but
I measured my plane and the dimensions are: 5 and 1/8 inches from
the bottom of the lower longeron, and 44 inches forward from the
center of the cross tube back near the tailwheel....I think it's the
only crosstube that is near there that protrudes through the fabric.
This does place the port just in front of the lift handle, but quite
low on the side. Is that where yours is?

With the tube going forward it can exert a considerable stress on the cross
tube. That in turn coulddamage your exterior finish. If the long tube ever
broke or came free it could possibly foul your rudder cables or elevator
tube.... Mr. Murphy is alive and well let's not tempt him Smile

Huh? Are we talking about the same tube here, Noel? I was talking
about the 3/16" or 1/4" nylon tube that carries the static pressure.
In my case I had the two side static port tubes going into a tee,
and from there forward about 12" to a tie wrap around a fuselage
cross member. From there forward, the tubing was supported every 12"
or so with tie wraps done in the approved way...with standoffs. My
tech advisor wanted a bracket to support the tubes at the "tee." The
side tubes curved upwardly to the tee, thus there was some vibration
absorption going on via the curved tubing...nylon tubing. Are you
suggesting this nylon tubing is gonna foul my rudder cables or
elevator tube?

You already know the right way. But I'll add that my 582/IV has the battery just behind the firewall and its CG is "too far" aft, which means I can't run 40 pounds in my baggage compartment at full gross without going aft of the rear CG limit.

Well, according to my manual for my Kitfox IV 1050 it states behind the seat is where battery goes with the 582 and the dash fuel tank.

One can always rely on AC 43.13 2a for specific information, such as static system installations.

Go to this FAA link

That should read:

AC 43.13 1b not AC 43.13 2a

Although...., in AC 43.13-2a you will also find battery installation information

Correction:
The battery installation link has been revised
Use the link below to go to the page that includes Chapter 10.

No... I was referring to the long tube you have properly supported. I can still appreciate why you friend wanted the “T” supported. That area of the inside of the fuselage could be a lower pressure area. That would make your Alt read too high and your ASI read too low. That and it’s just not right to have anything flopping around in the plane.

My set up is very primitive. It consists of a large static port just forward of the left door. There is no balancing port on the other side and to be honest I would be hard put to choose a worse location for a static port. When I run the engine up for the first few seconds the ASI,VSI and Alt go crazy. It all straightens itself out before I get up on step though. For that reason I have taken to flying with the static port open to the cabin. It’s a lot more consistent but I have noticed slight (very slight) differences in the static instruments when I open the door in flight.

Any chance the next time you are poking around in your fuse that you could take some pictures of your static installation. I have been considering installing a better installation.

Because every plane is different... not to mention the weights of the batteries that can be used, I still say the best thing to do is weigh the plane and calculate a W&B. Then you will know for sure where the battery should go. Weighing the plane before everything is torqued down permanently would be a good idea because the further back the battery goes the more heavy copper cable will be needed and the more complex the installation.

I like to keep battery cables short. There is less chance for getting the cable pinched or shorted. Less voltage drop and less weight.

Glad to see lots of people here use AC43... It’s the basis on which good aircraft maintenance is built. I even have downloaded the whole of AC 43 to my PDA for quick reference when working on planes.
There is a word of caution though.... AC43 is the rule but there are exceptions that make the rules. Those exceptions are all well written in the aircraft manuals. In our cases we essentially write the manuals when we build the planes. There may be cases where things are done contrary to convention Fir good reason. It’s good to be aware such conditions exist.

If there was one thing in AC43 I would suggest everyone read and practice it is lock wiring (Safe tying). It is not difficult to learn to do well and nothing finishes a job off like a nice clean, even and taught job of lock wiring. Once you get good at it you will be using wire everywhere to do things you never considered before, both on the plane and around the house.

We are lucky we don’t have to contend with the paperwork the GA crowd has to contend with. A few years ago there was an essay question on the Transport Canada AME final examination on the procedure to adjust the flaps of a BPY or Catalina water bomber. The incorrect answer is: There is no flaps on a Catalina. (True but not correct) The correct answer is: The Maintenance manual for the Catalina does not describe an approved method to adjust flaps.

Exactly right.
A certificated aircraft's manual contains "Approved Data",

AC 43.13-1b, 2a contains "Acceptable Data", often used and referenced when seeking approval from the FAA for repairs and modifications to certificated aircraft when specific "Approved Data" is unavailable.

All of it can, and should, be applied to Experimental Amateur-Built when in doubt.

I'll try to attach the pics that I had in my files, but even though I
reduce then as Matronics asks, I always get a "rejection
letter"...and then they show up anyway. If they don't show up, I'll
send the three pics to you, Noel.

This is before I had installed the right-hand side tubing.

This is up through the inspection hole opening, with temporary stick
holding support in place while adhesive hardens. It's hard to not
make a mess with the adhesive when you're working through the hole.
Another shot of temporary stick. I had to install this support brace
with one hand through insp. hole. The support has many holes drilled
through it to allow the adhesive to ooze through and form a "rivet"
of sorts. It also jams between the fuse tubing and the antenna plate,
so there is mechanical, as well as adhesive attachment. Getting a
machine screw into the (eventual) adel clamp was a joy, too!

Noel, My 912 engine mount came off of a model 3. I don't know if it will fit your plane. I'm sure someone out there knows. I also have the grommet door that goes in the middle of the firewall. Shipping to Newfoundland must be expensive from almost anywhere. Pat Reilly

I’m in Newfoundland, Canada... As close as you can get to Europe on this continent without doing a lot of swimming. J

I’m going to hold on to the 582 until I get the 912 flying then it’s up for sale, lock stock and barrel.

What model Kitfox is your mount made to fit? That’s the big part I need now. My bolt pattern should be the same as the model II.

Noel, Sorry, no, I do not have the 912 exhaust. I got this plane without the engine. I have the complete 912 engine mount and the firewall grommet door, however. What are you doing with your 582 firewall forward? Where are you located? Pat

Pat

I’m going the other way installing a 912 where a 582 now lives. I’m considering moving my header tank, almost 14 lb full, behind the seat. Then putting the oil tank where the header is now, behind the instrument panel. I have to see if it will be easily removable form that location for cleaning. BTW you don’t happen to have an exhaust??

Tom, Thanks for the advice. I have removed the battery. I am 90% sure it will have to come forward with the lighter engine. But, I will wait to reposition it with the new weight and balance. Pat Reilly

Pat, I would leave the battery where it is until the rebuild is complete enough to do a close weight and balance. Then you can move the battery forward if needed and you will be able to know how far. It will probably be easier to remove the existing cables at that time than to reinstall them if you need the CG to move back.
