Just change the O-rings from the standard Nitrile (Buna-n) to EPDM and
you're go to go. The sizes used are 2-110 and 2-113 for the Cleveland masters
and
2-218 for the Cleveland calipers. Just spec these sizes in EPDM. Ace Seal
sells them. Check the Yeller Pages for contact info.
If you have anything else in the lines such as a parking brake valve or
shuttle valves, you're own your own to determine the seal sizes you will need.
How much easier do you want it?

Dean,
You're right except for a few small points:
The new oplims require you to comply with 91.319(b) which
requires one to demonstrate that the aircraft is controllable etc. It's
not strictly speaking phase 1, though.
The new oplims require you to notify the local FSDO of the
location of the proposed test area and obtain concurrence as to the
suitability of the test area. (Note: you do not have to have their
permission to do a modification and you don't need an inspection.) The
notification and concurrence could be as easy as a phone call to the
FSDO if you plan to use the test area that's spelled out in your oplims.
I'd make a note in the maintenance log of who you talked to and the
date/time just to be covered.
If the major change includes a different make or model of engine
or prop, you've got to fill out a revised form 8130-6 application for
airworthiness certificate.
Pax,
Ed Holyoke

Hi All-
>An even easier idea is to stick a piece of scotch brite....
Shortly after getting started, I had the great god fortune of getting to
know a serious airline tinsmith who showed me more simple, real world
solutions to issues in the shop than you could shake a stick at. One of
them applied to cinching gapped sheets of aluminum. Just put the rivet in
the hole, and give it a light tap, just enough to make the rivet swell to
the point of not falling out of the hole. Move the bucking bar to the
sheet metal adjacent to the rivet shank and give it another light tap, and
listen for the pitch change, much as when a rivet sets tight. The sheet
metal will now stay cinched for the rest of the operation. Put the bucking
bar back on the rivet and drive it home. Poof, you're done! No extra
parts or hands needed.
I hope this helps you guys as much as it helped me-

Subject: | firewall penetration points |
--> RV-List message posted by: "Glen Matejcek" <aerobubba@earthlink.net>
Hi Erich-
I'm not building a -7, don't have the same engine you do engine, and didn't
sleep at an HI Express last night. No of that stops me from having an
opinion, tho! I found it to be very valuable, if slightly inconvenient, to
hang the engine before penetrating my firewall. Also, and although those
eyeball penetrations are sexy, they are also relatively expensive and I
have reservations on their performance in an engine fire scenario. I used
Bob Knuckolls / Aeroelectric list shower bar solution, and found it to be
great. It's a homebuilder's version of what Beech seems to use.
I took a SS / handicap shower grab bar and cut the ends off of it just
inboard of the radius. I found a convenient spot at the far left and right
edges of the firewall to bolt them on with the open end pointing
more-or-less towards the center line, and then cut my holes. When final
mounted, they are sealed to the firewall with intumescent caulk. this
gives me a 1 1/4 hole through the fire wall to pass all sorts of stuff,
including all the engine cables, battery cable, MP line, P leads, bowden
cables, etc. The penetration on the other side of the plane gets the
sensor wiring. The open end of the SS tube get trimmed to any convenient
angle to allow for the engine cable runs. There is an appropriately sized
bit of firesleeve with one end clamped on the SS and the other on the wire
bundle. When I'm confident I won't be adding any more stuff to the
bundles, I may well seal the SS tubes up with more intumescent caulk under
the firesleeve.
This solution may not be as pretty as the eyeballs, but it is very cost
effective, versatile, possibly safer, and allows for future expansion
without cutting any more holes in your firewall.
As ever, FWIW, YMMV, etc-

Thanks to those who responded about the availability of an RV-8 RC model.
Still haven't found one, but came across a survey on rchomebuilts.com that
the company uses to develop and produce new models. Anyone interested in
having them put out an RV-8 should fill out their survey and let them know
that there is a market for it.

In general I agree with what you are saying but as far as the penetration
points for the Throttle, Mixture and Prop, the expensive eyeball
penetration gizmos are very handy, especially if you have to remove, repair or
replace the cables for any reason later down the road (think maintenance)
and no need to remove a bunch of caulking at that time. And I think they
will hold up in a fire quite well as they are pretty beefy. Also, most
builders do not run the throttle, mixture or prop with other electrical
wires/cables through the firewall. I like using the eyeballs, they work for me.

Subject: | Wings before engine? |
--> RV-List message posted by: Geoff Evans <hellothaimassage@yahoo.com>
Does anyone have any experience, positive or negative, with installing the
wings before doing anything with the engine? It seems like most builders do
it the other way around, but perhaps that's because they have limited
construction space. I'm building in a hangar, so that's not really a factor
for me.
I haven't ordered my engine yet (for monetary reasons), and I want to keep
making forward progress. I also want to have as much of the plane completed
as possible before starting on the engine, so as to minimize the time between
engine delivery and actual flying (my building schedule is somewhat
sporadic). However, I don't want to put the wings on if it's going to
significantly hinder access or be an inconvenience to engine installation and
associated plumbing.
Thoughts or comments?

Geoff, haven't done it that way, but the tail is awful heavy w/o engine.
Lot depends on whether you're bldg a tail dragger or tri gear. If latter
you'll definitely have to support tail. I would think the main gear would
be more of a prob. on a tail dragger. In both cases I believe the wings
would be a problem for plumbing. I'd put the eng. on first. My opinion is
based on tri gear bldg. Good luck!

I think the process has you mate the wings once to drill the
rear spar attach hole (I'm working on a 9 so your mileage may
vary), drill the wing root fairings and the center section
bottom skin screw holes. At that point you pretty much have to
take them off again to complete the installation of the
platenuts etc.
After that's complete you could put them on permanently if you
wanted to. But why bother ? They consume a lot shoe leather
because you have to keep on walking aaaallll the way round the
plane to pick up that tool you left on the other bench. Also
they're a nice big fat target for dropping a clecoe or a wrench
- they're a lot less of a target when they're stood up in the
wing stand.

Geoff,
I'd wait with the wings as long as possible. They just get in way.
You'll spend a lot of time walking around those wings if they are on.
If everything is set up properly ahead of time it shouldn't take but
half a day to install the wings, hook up wires and hook up pitot tube.

My advice is to NOT install the wings until everything else is finished.
Even though you're in a hangar, they will definitely be in the way and
about the 400th time you have to walk around them to get from the engine
to the cockpit, you'll wish you'd waited.

IMNSHO (In My Not So Humble Opinion) do as much as possible without the
"final" wing attachment. It's a whole lot faster & easier to stand, work,
slide up & down the fuselage, reach both sides of firewall than to walk all
the way around the wings, crawl into them & then work while on your knees.
90% done with 90% to go is an old antage but true. I would do everything
possible without the wings attached. KABONG HRII N561FS Do Not Archive.

Subject: | Re: RE: Brake fluid-Skydrol |
--> RV-List message posted by: Jim Oke <wjoke@shaw.ca>
I strongly suspect that a DHC-8 with a blown prop seal would be spraying
turbine engine oil and not skydrol hydraulic fluid about the aircraft.
(The prop blade pitch system is driven by engine oil pressure and not
the aircraft hydraulic system). For Dash-8 operators, the usual,
although not-government approved, method of differentiating between
engine oil leaks and hydraulic leaks is to do a quick taste test; if
your tongue burns and tingles that would be Skydrol and not turbine oil.
I fly earlier model D-8-100s at work and see enough skydrol leaks to
want to stay away from the stuff. It is face shield and rubber glove
time when the maintenance guys are working on the hydraulics. Any
persistent skydrol leak is usually cause for my company's high quality
polyurethane paint to bubble up and disintegrate. Other than the health
and safety issues, skydrol comes in the usual tins and seems to need no
other handling procedures than 5056 fluids.
The reason that the DHC-8 uses skydrol is indeed a slight improvement in
flammability and flash point properties over other fluids.
Interestingly, the DHC-8s I fly still use Mil-5056 fluid in the landing
gear shock struts although the brakes themselves use Skydrol.

Skydrol is highly toxic and it is flammable. Also, it is not compatible with hydraulic
seals and hoses designed for 5605 fluid.
See http://www.skydrol.com/pages/glove.asp and http://www.skydrol.com/pages/faqs.asp for all the specifics.

Geoff,
I see many replies to your above message, but I'm not sure we understand the
question. When you say "install the wings", do you mean temporarily to fit
up things like flaps, root fairings, belly skin overlap area, fuel and vent
lines, upper gear leg intersection (if a trike, I see yours is a TD),
aileron rigging, etc.? Or, do you mean final installation? If you want to
delay engine purchase (a good thing), there is a fair amount of work related
to fitting the wings which could be done now if you haven't already done so.
Once all this is completed, it is easy to remove and store the wings so as
to not have to walk around them.

Stormy,
To the best of my knowledge:
The only way it would void your car insurance is if the underwriters can prove
in court that the transmission was the cause of the accident. But then, you are
protected by the MIL-itary, so maybe you get away with it? Other than that

In general I agree with what you are saying but as far as the penetration
points for the Throttle, Mixture and Prop, the expensive eyeball
penetration gizmos are very handy, especially if you have to remove, repair
or
replace the cables for any reason later down the road (think maintenance)
and no need to remove a bunch of caulking at that time. And I think they
will hold up in a fire quite well as they are pretty beefy. Also, most
builders do not run the throttle, mixture or prop with other electrical
wires/cables through the firewall. I like using the eyeballs, they work for
me.

Charlie, I agree with Keith. I spent 38 years with UAL in aircraft
maintenance. You do not want anything to do with Skydrol. It is one of the
nastiest fluids in the aviation industry. Adding to what Keith said, it will
remove paint, create coking if in contact with exhaust stacks, is very
irritating to the skin and is very painful if you get it in your eyes.

Ditto. And I wonder how all those *aluminum* rivets are gonna hold up in
the event of a fire. I hear people yappin' about heat flapper valves and
bulkhead fittings and eyeballs and all that, and I don't disagree. But
nobody mentions how the firewall will basically be trying to "fall off" if
the aluminum rivets melt in a fire. I don't know what I'm talking about,
not speaking from experience, just kind of philosophizing here. But I
wonder about all dem aluminum rivets. If a fat aluminum eyeball melts,
surely the rivets will as well, right?

Very good point Dan!! About the only thing holding the firewall on in that

in the first place. Just my 2 cents. Don VS

Mr, Hall,
I think you are confusing who said what, in regards to Skydrol. My
original comment regarding Skydrol related to the fact the EPDM is a
suitable sealing material for it's use. I never endorsed it's use for our
RVs. See original comment below.
The subject line of my post was DOT-5 Brake Fluid.
EPDM is listed to compare Viton's capabilities with one of the most common
materials used in automobiles. EPDM is NOT compatible with mineral based
hydraulic fluids, such as 5606 or ATF. Interestingly, it is good for use
with Skydrol. However Skydrol has draw backs which make it less than ideal
for light aircraft use. (Toxic, not readily available at small airports,
expensive, and burns at an elevated level)
Dean P replied to my comments, regarding Skydrol being toxic. I believe
that Dean was questioning me on a point of semantics. I used the word
TOXIC. Dean correctly challenged my use of the word toxic, as it regards to
Skydrol. From the data I've read, it would be more accurate to call it a
tissue irritant. From your description, it is a rather nasty one. At that
point, everyone else jumped in. Please correct me if you can show me where
in any recent email "I" suggested anyone use Skydrol in light aircraft. I'm
not trying to start an argument. I'm simply trying to keep who said what,
straight. I do appreciate hearing about your experiences with this fluid.

Mine are aluminun,curved to wing contour and only 1/2 " tall. I love them

Does anyone have any experience, positive or negative, with installing the
wings before doing anything with the engine? It seems like most builders do
it the other way around, but perhaps that's because they have limited
construction space. I'm building in a hangar, so that's not really a factor
for me.
I haven't ordered my engine yet (for monetary reasons), and I want to keep

Dan,
I was wondering the same thing just last night. I'm just starting on the
firewall. Do certified aircraft use stainless rivets on the firewall? I was
an A&P years ago but can't remember. I don't think I ever repaired any
firewall rivets.
I had decided not to worry about it since it seemed everyone was using
aluminum rivets. And Don has the right idea...do everything right, to avoid
a fire.
Has anyone installed a fire extinguishing system on the engine in an RV?
Seems like it would be relatively simple. Mount a small halon extinguisher
somewhere where it could be reached. Then run a hose out to the top front of
the engine.
Some Cessna twins have a bottle in the wing root that is electrically
activated.
And a hose (stainless braided) runs to the front of the engine. This is from
memory from years ago...
Just a thought.
