Just to follow up: my AF2500 engine monitor installation manual specifies
25-30 in-lbs for the CHT probes.

I'm wanting to install the CHT probes, but I can't find any information
as to what to torque them to. (oddly enough I found the info for
torquing the stainless steel bands that hold the EGT probs (45 in lbs).
Also do they get any sealant applied to the threads (anti-seize?)
Anybody got any insight here?

I know we just had this discussion about a leaky rivet on a fuel tank. I
didn't comment because I thought I was the lucky recipient of leak-free
quickbuild tanks. You'll notice from the attached photo that I was not. Seeing
that
did not make me happy.
Last August I pressure tested my tanks using a pressure gauge from a blood
pressure cuff before installing them. I pumped them up to 35 mmHG (~ 0.67 psi)
and left them for 2-3 days. The pressure did not change so I figured they
were good. After filling them I checked for leaks and didn't see any. I've had
fuel in the tanks for 10 months and flown 85 hours. As I was washing the bugs
off my wing yesterday I found this leak. I'm glad I found it before painting.
I plan on emptying the fuel from the wing and trying the Locktite 290
approach, unless someone has a better suggestion.

Kevin, I used Bulb seal, Item BA-1900010 from Brown Aircraft Supply
in Jacksonville, FL. 904-396-6655. The only thing I don't like
about it is that it leaves a black mark that I clean once in a
while. However, the doors operate nicely and they are sealed. You
also need Rubber and Gasket Adhesive by 3M, part 1300L to attach this
thing.
You may want to get their one page catalog and make your own
determination. I think that they only sell door seals.

You are lucky that it is only leaking from the rivet. Mine QB leaked
in several places resulting in much debates, head scratching and a
big hole on the rear of the tank to do repairs.
The 290 WILL work. My rivet leak has held up for a year now. I
would put the same amount of neg. pressure on the tank while applying
the 290 and let them sit overnight.
Do not archive.

Should be no argument about part 91 applying to experimentals. ALL of FAR part
91 applies to experimentals, it's the part 23 that does not. As another message
indicated, for the certified aircraft with glass panels, the steam gauges
are primary and the EFIS are secondary. They must have good reason for doing
this and unless one has data showing otherwise, I'd follow their model.

a "magnetic direction indicator" for both VFR and IFR flight. Although one
might argue 91.205 doesn't apply to experimental aircraft, the simple fact is
that you will be at the mercy of the DAR who does your final inspection, and my
guess is probably the majority of DARs will have the same expectation for homebuilts
and standard aircraft, especially because most of us are building our
-10's for a cross country mission profile that looks like what folks use Cessna's,
Pipers and Mooneys for.

Subject: RV10-List: RV10 Flyoff time
I wanted to pass on a quick note to those interested in how my DAR check and
Flyoff went. I got DAR approval on Tues at 2:30. We put all the fairings
and inspection covers on and I was in the air at 4:30. I flew 2.7 hours
that day and developed a LOW oil pressure issue. I called the engine
builder on Wednesday to discuss it and he said is needed a new spring and
ball in the pressure adjustment cap. He Fedex it to me on Thursday at noon.
Come to find out what I really needed was an aluminum SEAT washer that the
pressure check ball fits into.
That SEAT came loose and fell out.........which is NOT suppose to happen.
The oil was leaking around the seat and registering LOW pressure. After
fully inspecting the motor to confirm it was NOT making metal we FLEW a
Baron to Omaha, NE to get the new SEAT, flew home and the landing gear would
not go down!!!!!
PLUS it burned 50 Gals. of fuel in 60 minutes. After cranking the
gear down and doing a fly by to verify it was down..........I got the new
seat in the plane. Viola.....66 PSI oil.........winds were 36 mph
45 degrees to the runway...........UP I went. I flew 3.6 hours in very
gusty conditions.........one landing I had full RUDDER and a 48 MPH GS . I
thought my ankle was gonna break with those gusts hitting the
rudder.......then you have to get it taxied with that nose castering in the
wind!
Friday was a good day..............9.0 hours flown..........Saturday was
great also..............flew 9.2 hours for a total of 25 hours in 4
days!!!!!! Oh yea......today we had a HOT mag....the P lead broke off.
I am now gonna go get some sleep.........until SUNRISE...........then I have
a few friends that want a RIDE!
I still find it hard to believe we got this bird flying and done (painted
with wheel pants)in less than 2 years. Oh yea........VFR........no Wet
Compass yet. But I still would buy a good
handheld GPS before a $250 compass (JMHO)
If you are building ,.........keep bucking it is all WORTH IT! This
plane is UNBELEIVABLE in the air! See you all at OSH '07. Thanks
to all on this list who helped with friendly advice and counsel. I also
wanna thank those who MOTIVATED us to build a great plane on a BUDGET.
It can be done and done very respectably. :) Ask me AND Van! I did
spring for seat covers though unlike Vans plastic, over foam, wrapped in
Duct tape.

check and Flyoff went. I got DAR approval on Tues at 2:30. We put all
the fairings and inspection covers on and I was in the air at 4:30. I
flew 2.7 hours that day and developed a LOW oil pressure issue. I
called the engine builder on Wednesday to discuss it and he said is
needed a new spring and ball in the pressure adjustment cap. He Fedex
it to me on Thursday at noon. Come to find out what I really needed
was an aluminum SEAT washer that the pressure check ball fits into.
That SEAT came loose and fell out.........which is NOT suppose to
happen. The oil was leaking around the seat and registering LOW
pressure. After fully inspecting the motor to confirm it was NOT
making metal we FLEW a Baron to Omaha, NE to get the new SEAT, flew
home and the landing gear would not go down!!!!!
PLUS it burned 50 Gals. of fuel in 60 minutes. After cranking the
gear down and doing a fly by to verify it was down..........I got the
new seat in the plane. Viola.....66 PSI oil.........winds were 36 mph
45 degrees to the runway...........UP I went. I flew 3.6 hours in very
gusty conditions.........one landing I had full RUDDER and a 48 MPH GS
. I thought my ankle was gonna break with those gusts hitting the
rudder.......then you have to get it taxied with that nose castering in
the wind!
Friday was a good day..............9.0 hours flown..........Saturday
was great also..............flew 9.2 hours for a total of 25 hours in 4
days!!!!!! Oh yea......today we had a HOT mag....the P lead broke off.
I am now gonna go get some sleep.........until SUNRISE...........then I
have a few friends that want a RIDE!
I still find it hard to believe we got this bird flying and done
(painted with wheel pants)in less than 2 years. Oh
yea........VFR........no Wet Compass yet. But I still would buy a good
handheld GPS before a $250 compass (JMHO)
If you are building ,.........keep bucking it is all WORTH IT! This
plane is UNBELEIVABLE in the air! See you all at OSH '07. Thanks
to all on this list who helped with friendly advice and counsel. I also
wanna thank those who MOTIVATED us to build a great plane on a BUDGET.
It can be done and done very respectably. :) Ask me AND Van! I did
spring for seat covers though unlike Vans plastic, over foam, wrapped
in Duct tape.

I was looking back in the test flight logs of my RV-7 and in the middle of the
test program I did a couple of days with four 2 hour flights each. Wasn't really
that big a deal since I had a set of test flight cards already made up, and
it was just a matter of pulling out a card, and then 'planning the flight, and
flying the plan'. A fair amount of that time was spent with the TruTrak flying
the plane while I recorded the test findings, and got set up for the next
manuver. With an adequate break between flights on these long June days, 9 hours
wouldn't seem a stretch in a low workload plane like the -10.

What if one of you smart MIT types *cough* figure out about how much PSI
a full tank of avgas exerts while compensating for the difference in visco
sity between air and avgas. Should give you a better number to use to appr
ox the PSI of air for testing the tanks. Hopefully it will lead to more ac
curate leak tests.
Just a thought. :-)

Subject: RV10-List: Fuel Leak
I know we just had this discussion about a leaky rivet on a fuel tank. I di
dn't comment because I thought I was the lucky recipient of leak-free quick
build tanks. You'll notice from the attached photo that I was not. Seeing t
hat did not make me happy.
Last August I pressure tested my tanks using a pressure gauge from a blood
pressure cuff before installing them. I pumped them up to 35 mmHG (~ 0.67 p
si) and left them for 2-3 days. The pressure did not change so I figured th
ey were good. After filling them I checked for leaks and didn't see any. I'
ve had fuel in the tanks for 10 months and flown 85 hours. As I was washing
the bugs off my wing yesterday I found this leak. I'm glad I found it befo
re painting.
I plan on emptying the fuel from the wing and trying the Locktite 290 appro
ach, unless someone has a better suggestion.

OK, I am a short way from testing my QB tanks. If I do an air pressure
test, and the test fails, how will I find any leaks? Soap?

Dave,
I'm no expert, but I actually did sleep in a Holiday Inn Express last
night, so I'll throw in my .02.
I don't consider the soapy water check a secondary check to be done
if the air pressure leakdown fails...it's more of a primary test.
I did both, at the same time. First, pressurize the tank with the
balloon attached, and then spray it with a diluted concentration
of dish soap and water with a spray bottle. Any bubbles coming
out will grow and should be easy to spot. Check EVERYWHERE.
Then, leave the balloon full and see how it is the next day. If
it is still full, you're done. If it isn't, then you probably
need to do the bubble test again, and you'll most likely find any
problem if there is one. Other than a loose rivet, the air should
leak way easier than the fuel would. If you really want to get
a the bubble test down to a fine level, use helium and that will
easily find its way out any tiny spot, but that's way overkill.
It's interesting to see how the tanks are becoming the downfall
of the QB wings. Personally, I was much much happier to build
the tanks and KNOW how they were built than I would have been
to just buy them pre-built. It would be different if you were
buying from an aftermarket tank builder who would guarantee
them, because they'd take extra pride in their work. IMHO, people
make a little too big a deal out of how awful the tank building
job is...it just isn't that bad.

You know Chris, that is a very good point. I am getting close to
pressure tests and will keep this in mind.
