Subject: Re: RV10-List: Glasair III Engine/Fuel Problem
The real goofy part about all this is its intermittent. So far we've been lucky
that every time its happened near an airport.
I'll have to check the Glasair manual to see where all the filters are, but we've
checked the servo screen, divider, injectors, gascolator, and replaced fuel
filter. Have not checked fuel selector or if there are any screens there or at
the tanks.
Air is the other part of the equation, and now that its mentioned, I do not thinks
its been checked. I guess the air filter and alternate air are the only points
to check?
Have not check the fuel flow into a bucket (have flowed the injectors - OK). The
difficult problem is the intermittent nature. Fuel flow and pressure seems OK
on the gauge (on the ground when the OK runups are done), but to be honest,
when you're at 800' with a badly missing engine, gauges are secondary to getting
on the ground. Boost pump makes no difference when it happens.
Are there screens at the selector? Any other screens in the fuel system?
Engine has 200 hours, built in 1990 and checked again in 1994. The fuel had crap
and water in it when I picked it up, but its been cleaned up. That's the reason
we've suspected fuel contamination and spent a lot of time getting that cleaned
up, but air is something we must check too. I'm not a mechanic, but I wonder
why they didn't check that too (or did they)?
Remember before taking to the air (initially and after each "fix") we've done complete
high power runups and all was fine. The engine ran good in the air on
three occasions for about 15 minutes (taxi, run-up, takeoff, climb, cruise, and
on one occasion - descent and touch and go) before it started the roughness/misfiring/loss
of power. Mag checks are good.
One more item: The time it happened orbiting the field, we got to 2500' before
it started again. I reduced power to 17.5" and it ran fine, but it would take
no more throttle. Orbiting at 17.5" I checked boost pump/magnetos - worked fine.
I did not check FF/pressure as the EI 800 gauges on this plane seem unreliable
(plus I probably forgot in the commotion).
Engine compressions are between 62-72. Attitude seems to make no difference (mine
or the airplanes).
Help?!?

I roughed the WD-415 with medium grit sandpaper then wiped with acetone then a
clean dry cloth before priming. Almost 2 years since completing that section and
still have good adhesion. As for the nutplates I have been using the same old
scotchbrite scuffing method that we are all SOOOOO familiar with. Good results
so far.

| Subject: | Glasair III Engine/Fuel Problem |
I had fuel problems on my Glasair III that were caused by a leaking o ring
on the fuel filter canister. It was intermittent, and drove me nuts until I
found it. All Gaskets should be replaced in the filter and housing when
changing the fuel filter. I could solve my problem with the boost pump
though, so I am not sure your problem is the same as mine, but checking the
gaskets is always good.

Ed,
I am using Akzo, but haven't gotten to any of the non powder-coated steel
parts yet. I was looking at the trim cable anchor bracket the other day
(I'm not too far from that point) and thinking about that though. I think I
will just clean the parts really well, then use a q-tip or something to put
a thin layer of grease just in the threads so that the primer doesn't stick
there. Seems like there should be a better way though. I also thought
about putting a sacrificial bolt or piece of threaded rods in to keep the
threads clean. Might be hard to get out if you need to back primed threads
through the part.
I was also looking at the trim cable anchor bracket and wondering about its
durability. This part looks like something I could have made in shop class,
and doesn't give a feeling that it is very robust like other parts on the
plane. Is anyone aware of a 3rd party vendor replacement for this piece? I
thought I remember something like this from a while ago but maybe it's just
my poor memory at work.

After several un-productive phone calls with Aircraft Spruce, I am back at square
one with lock sets. I am trying to piece together the ignition switch, baggage
door lock, and 2 cabin door locks, all keyed the same. Aircraft Spruce says
that I have to buy 2 of their ignition/lock sets and then pay a special order
fee to have them keyed alike. The total comes to almost $300. While a drop in
the bucket in the grand scheme of things, there has to be a better way. Does
anyone out there know of another source to get such a package of lock sets?

I'm 40720 so pretty much right with you as far as parts received. I
received a pretty good piece that I think is quite fine, the older piece
was a welded weakly issue.
As far as options, (assuming you have three months to wait)
http://www.rivethead-aero.com/rv10_005.htm
I ended up priming the whole piece, there has been no issue with placing
the cable and it holding fine.

Hello guys,
my intense full time 4 month building time is now coming to an end. (no I am not
done yet).
I'd like to thank you all for your great support during this time.
I hardly ever experienced such a friendliness and support. Especially being located
in Europe I posted a question in the evening when I got home from the workshop,
went to bed and in the morning for breakfast I read through all the answers.
I'll now go traveling with my wife to Australia and hope to visit RV-10 builders
there, thanks to Chris & Susie, Pat and John we looking forward seeing you.
There is truly such thing as the RV-Family.
Take Care and which you lots of progress!!!

Here are some picture of tiedowns I made out of hinge material. We're
getting ready to make these available for sale--they should be on the
website in a few days. Price will be $49 for a set of 4. I've had 72#
strapped down for all my phase one so far and they're working great. The
return on the movable side is to keep it up above carpet level.
Let me know if you need a set. We'll have a couple other RV-10 specific

| Subject: | Radio Static Help |
4 years ago today I placed my order for RV-10 tail kit #40134 as a birthday
present to
myself. Now, 2500 building and 100 flying hours later, I can say it was a
pretty nice gift
and well worth it... unfortunately I haven't got all the bugs worked out yet:
I've spent the last few weeks trying to track down a problem with radio
static on my
Garmin SL-30 Nav/Comm. The SL-30 is attached to a Garmin GMA-340 Audio panel.
The static itself sounds random (i.e. not obviously uniform like I would
expect from an ignition
system), however, it is somehow associated with engine throttle setting. The
static starts around 2000 RPM and gets progressively worse as throttle
increases.
On takeoff, it is so bad you can not comprehend any received transmissions.
During cruise it appears
to be somehow associated with manifold pressure (i.e. throttle setting, not
RPM). It makes
listening to ATC difficult to impossible. I also think it may be affecting
my radio
transmissions as well, because when I have a hard time comprehending ATC,
they
also have a hard time understanding me. This static appears to be only
affecting
the Comm audio, there is no static on NAV audio reception. I have a belly
mounted
bent whip VHF antenna and a wingtip VOR antenna. My handheld ICOM VHF radio
does not have any static when used inside the cockpit.
I have searched various lists for ideas and tried to solve this problem, but
I have had no success in changing it at all (for better or worse). Any
suggestions for what to try or where to look will be welcome. Below is a list
of some things I have tried with no luck.
General
-Shut off all avionics (except SL-30) and both ignition systems (not both at
the same time)
--So it doesn't appear to be interference from other electronics
Antenna/Coaxial cable
-Added ferrite signal filters at various locations along comm coax.
-Connected SL-30 to a different comm antenna using a piece of RG-400 (tried
various routings to antennas)
-Connected SL-30 Comm to VOR antenna (great reception, still static)
--So it doesn't appear to be antenna related
Power/ground
-Ensured engine grounding cables have good contacts on both ends
-Apparently new Slick Magnetos have internal suppression and do not need a
filter
-Separated SL-30 power/ground leads from bundle to reduce potential
interference from other wires
-Ran SL-30 +12V and ground leads directly to battery
-Disconnected serial connection between my SL-30 and EFIS indicator
-Connected SL-30 to separate 12V battery sitting on floor of aircraft,
disconnected power/ground
to GMA-340. Attached ICOM handheld antenna directly to unit (SL-30
completely isolated
from aircraft)-reception still has static
-Ran ground wire from battery to SL-30 tray
-Checked to ensure headseat jacks were isolated from aircraft ground.
-Checked the shield connections for tachometer and fuel flow sensor wires
I can't think of anything else to try. Again, I'd be happy to hear any
suggestions.
Thanks.

Erik
My solution was to buy the ignition switch from Vans. Their switch includes
two additional door/baggage locks.
I needed one more lock, so I called Aircraft Spruce customer service and
talked to a very helpful lady (Robin I think).
I gave her my key number and she ordered a pair of locks keyed like the
ignition switch (they only come in pair).
So now I have a spare lock and enough locks to lock all the doors.
The total cost was less than half what you mentioned.

Jim,
Here are a couple thoughts:
>During cruise it appears to be somehow associated with manifold
pressure (i.e. throttle setting, not RPM).
Since compression in the cylinder is the only thing that changes at that
time, I'd check to make sure your ignition cables are not leaking
(Current and Voltage through the plug will change with differing pressures).
On your radio side, have you tried:
1. Connecting the end coax to a dummy load? This would check if your
coax is picking it up, especially when combined with your isolating the
power source for the radio (another battery as you already tried)
If you'd like, since you're local to me I can help and also check out
your antenna efficency (I have an antena analyzer).

You did not say if you have a second COM radio but I assume you do. If you
don't have static on the second COM then you might try swapping radio
position on the GMA340? Or possibly use the built in 2 place intercom on the
sl30 temporarily bypassing the 340 altogether.

Steve Dinieri at Iflyrv10.com is close to having a stainless steel lock set for

RV-10 door handles, they will probably be worth it. Steve is a pleasure to deal

Here's an issue I chased for many months in my Glastar with the com
antenna on our GNS 530. (which feeds a 340 audio panel) The coax
connector we had used was one of those "non-crimp type" which had been
just fine for 7 years. Well after some moving around after our
instrument panel overhaul the connection to the shield of the coax
stopped making but the center lead was fine. The result was chaos on
the com channel. Noise and static and really weak transmissions.
I've since changed all coax connector to the much more robust crimp
type. NO issues since. This problem was very intermittent, at some
point I was convinced it was thermally related.

If it still had static with the hand held antenna and just battery power
, perhaps its actually an internal radio problem. Maybe you should take

The Cessna eyebolt tiedowns are awesome. I had some extras from my old 182 and
they are really great.
They screw (manually) into a standard (probably AN3) nutplate. I put two of them
on the rear baggage bulkhead. Reinforced them with a larger piece of thick
aluminum on the back side.
They are great because you can unscrew them and have a flat surface. They take
a standard (el cheapo) bungee through the eyebolt hole and are totally bulletproof.
If you can get a few out of a wreck or from the Cessna dealer they are great.
I have no idea what Cessna charges for the new ones.

| Subject: | Radio Static Help |
A few thoughts:
How does the intercom work within the cabin? Is there any static and does any
appear with engine at cruise?
I am not familiar with the G340 but have used the G347, PS engr, etc and they
default to com1 when the power to the intercom is turned off. There is a relay
inside that connects the pilots ptt, one ear, and the pilot mic directly to
the radio wired to com1 when power is off. This is the fall back mode. If your
SL-30 is connected to com1 how is the radio quality with the G340 turned off?
The antenna test as Mr Hein suggests is very valuable. I assume the results will
calculate VSWR. This test will verify the back half of the radio. Also, you
could buy a DB-25 plug and both the headset plugs and create your own direct
harness to the SL-30. Sit in the plane with the SL-30 in your lap and plug the
headset into the test harness. It only requires 7 (or so) wires. This will check
out the front half of the radio.
Good Luck,

Here's an issue I chased for many months in my Glastar with the com
antenna on our GNS 530. (which feeds a 340 audio panel) The coax
connector we had used was one of those "non-crimp type" which had been
just fine for 7 years. Well after some moving around after our
instrument panel overhaul the connection to the shield of the coax
stopped making but the center lead was fine. The result was chaos on
the com channel. Noise and static and really weak transmissions.
I've since changed all coax connector to the much more robust crimp
type. NO issues since. This problem was very intermittent, at some
point I was convinced it was thermally related.

You did not say if you have a second COM radio but I assume you do. If
you
don't have static on the second COM then you might try swapping radio
position on the GMA340? Or possibly use the built in 2 place intercom
on the
sl30 temporarily bypassing the 340 altogether.

Subject: RV10-List: Radio Static Help
4 years ago today I placed my order for RV-10 tail kit #40134 as a
birthday
present to
myself. Now, 2500 building and 100 flying hours later, I can say it was
a
pretty nice gift
and well worth it... unfortunately I haven't got all the bugs worked
out
yet:
I've spent the last few weeks trying to track down a problem with
radio
static on my
Garmin SL-30 Nav/Comm. The SL-30 is attached to a Garmin GMA-340 Audio
panel.
The static itself sounds random (i.e. not obviously uniform like I
would
expect from an ignition
system), however, it is somehow associated with engine throttle
setting. The
static starts around 2000 RPM and gets progressively worse as throttle
increases.
On takeoff, it is so bad you can not comprehend any received
transmissions.
During cruise it appears
to be somehow associated with manifold pressure (i.e. throttle setting,
not
RPM). It makes
listening to ATC difficult to impossible. I also think it may be
affecting
my radio
transmissions as well, because when I have a hard time comprehending
ATC,
they
also have a hard time understanding me. This static appears to be only
affecting
the Comm audio, there is no static on NAV audio reception. I have a
belly
mounted
bent whip VHF antenna and a wingtip VOR antenna. My handheld ICOM VHF
radio
does not have any static when used inside the cockpit.
I have searched various lists for ideas and tried to solve this
problem, but
I have had no success in changing it at all (for better or worse). Any
suggestions for what to try or where to look will be welcome. Below is
a
list
of some things I have tried with no luck.
General
-Shut off all avionics (except SL-30) and both ignition systems (not
both at
the same time)
--So it doesn't appear to be interference from other electronics
Antenna/Coaxial cable
-Added ferrite signal filters at various locations along comm coax.
-Connected SL-30 to a different comm antenna using a piece of RG-400
(tried
various routings to antennas)
-Connected SL-30 Comm to VOR antenna (great reception, still static)
--So it doesn't appear to be antenna related
Power/ground
-Ensured engine grounding cables have good contacts on both ends
-Apparently new Slick Magnetos have internal suppression and do not
need a
filter
-Separated SL-30 power/ground leads from bundle to reduce potential
interference from other wires
-Ran SL-30 +12V and ground leads directly to battery
-Disconnected serial connection between my SL-30 and EFIS indicator
-Connected SL-30 to separate 12V battery sitting on floor of aircraft,
disconnected power/ground
to GMA-340. Attached ICOM handheld antenna directly to unit (SL-30
completely isolated
from aircraft)-reception still has static
-Ran ground wire from battery to SL-30 tray
-Checked to ensure headseat jacks were isolated from aircraft ground.
-Checked the shield connections for tachometer and fuel flow sensor
wires
I can't think of anything else to try. Again, I'd be happy to hear any
suggestions.
Thanks.

| Subject: | TruTrak Pitch servo installation |
I am having a problem with the install of the (what should be easy) TruTrak Pitch
servo. The problem is that the Aluminum spacer that they include is too long.
I only have about .28" of space between the bellcrank bracket and the MM-3-300
rod end bearing. The TruTrak Pitch servo plans call for a (supplied) .438"
spacer in that space. If I put in that thick of a spacer the whole thing would
be very cattywhompus and would stress the drive on the servo and the bearing
on the bellcrank. (Yes, I did double check to see that I reinstalled the drive
wheel properly)
If anyone has had the same issue please let me know.
Also, as this has been an all day ordeal - calling Zach at Trutrak three times
today, I intend to post installation instructions for the servo tomorrow.

Jim,
Are you grounding your mag through a single conductor shielded wire, to
the switch, with the ground return (mags off) through the shield, and
then back to a ground location on the mag?
If not, your mag wire to the switch (with the switch open, ie: mags on)
is a great antenna to radiate mag noise into the surroundings.

Take the odd cylinders (and keys) to a locksmith and have them re-keyed
to match the others. Haven't a clue how much they'll charge though. A
DIY article is at http://www.rd.com/familyhandyman/content/18168/. I
just googled 're-key lock' and it was one that showed up. $8.00 for a
pin kit ...... but they're aimed at house door locks.

in the bucket in the grand scheme of things, there has to be a better way. Does
anyone out there know of another source to get such a package of lock sets?
