Morning all.
I would concur with mags however I would also look at 2 other factors and
especially as it appears to be on both mag positions although not uncommon
for heat soak to cause both mags to fail. (we had this on a Y50 recently 25
mins is the average. )
Lean mixture will also give these symptoms and also poor condition plugs.
Eliminate the plugs if you had just done that conversion, so Mixture.
Mixture - agreed filters blocking will lean the engine !! But subsequent
take off appears to be fine and that's at full fuel flow.
Induction leaks. - several items here. Carb loose - inlet oil drain kit
fitted and open (common) inlet tubes loose - inlet drain kit pipes cracked.
Back to the mags, has any one re magnetised the armatures? We have just made
the equipment to do this and have also commissioned new coils to be wound.
The first is here to be fitted maybe this week and then bench run. If anyone
has done the magnetising please do contact me. Magnets and coils make
sparks, its no good just doing half the job!!! I.e. changing coils.
Cheers, mj
Ps one winter ferry flight I had mags start to break down so opened all
gills to run the engine cool, this solved the problem till I got home.

The misfiring coil causes a complete purge of the fuel charge. That's
why you get the symptom of a complete engine shut down for a millisecond
or so.
I have discussed these symptoms with several M14 experts all over the
world and every one of them asks "how many minutes after takeoff before
you experience the problem?" The consensus is 20-35 minutes on the
average and you can pretty much bet it's a bad coil.
As for fiberglass being in the fuel system, this is always possible.
You can find out very quickly by removing both the course and fine fuel
screens and examining them for fiberglass particles.

Dear Dennis and Rodger,
Thank you both for your input, It would appear that this is the
problem according to the symptoms which appear to be identical to your
experience.
I will do the tests to make sure that it has gone away.
One thing that has me confused though,why does one bad mag cause all
this angst when the second mag is firing correctly, isn't that the
reason for two mags.?
I had a post from Michael Wikstrom in France who had a very similar
experience to mine,same symptoms again but his was caused by fiberglass
long range tanks that were dissolving and blocking the fuel filter with
glass strands.
My plane is fitted with the same fiberglass tanks,so I have bought
aluminium tanks fron Lithuania and will fit them when it arrives.
Seems there is more one way to skin a cat.
Thanks again
Bruce Thomas

Mark,
When you felt the air leaking out the elbow you should have just bit the
bullet and pulled the actuator and overhauled it. The problem will not
disappear and you may be in for a real problem if the landing gear does not
fully extend to down and locked. Far more expensive and time consuming than
overhauling an actuator.

My bet is you may have corrosion or garbage internally in the landing
gear handle/valve. Question - Why do you put the gear handle in neutral
versus leaving it in the down position when the aircraft is on the
ground? You may also have a leaking landing gear actuator. Does the
air pressure continue to decrease after the gear is down and locked or
when you turn on the main air supply valve do you continue to hear a
hiss coming from the gear handle/valve?
Glad you and your airplane are safe and sound though.

Hi gang,
Took the 18T to an air show at Branscombe today. 850m grass strip, no
problem until after parking including a long taxi in a strong crosswind
and a 180 degree turn to park beside the two P51's and a sole surviving
Hurricane. I run up to 60% for 15 secs and I notice the air pressure is
down to 2 1/2 Bar. I always check the pressure downwind (was okay as I
recall) and hope I did on final after lowering flap (I normally do)
but...... to be honest, can't be sure about that. Big crowd watching my
landing........... :-[
We have just had an annual done in Hungary and for the previous three
months have left the U/C in neutral on parking to isolate the leak which
has worked. On the 9 hour trip back from Hungary we have had no problems
despite the last minute fix to the nose gear actuating pressure lines.
We had a 10-15 second retraction time, replaced the air line, then okay
and within 5 seconds.
Assuming (Ah Ha - that old GOTCHA) that this is a re-occurrence of
that problem I move I U/C lever to neutral and lose another 1/2 bar as I
do so. No problem. I have a small cylinder for re-charge in the back. 5
hours later switch on air. Still 2 Bar. Recharge from cylinder to five.
Starts on second blade. Move gear to normal and lose 2 1/2 Bar
immediately back to 2 1/2. Engine running fine.....
Decide to go home and see if pressure builds in flight. It doesn't.
Alert 15 year old son in right seat to emergency gear possibility and
lower gear 10 miles out at 170kph to be sure. Full lock and three
greens. Now reading 2 Bar.
Storm clouds ahead but can move between gaps for my 650m home base
easily. Overfly strip and see wind sock limp between showers and elect
for uphill (5%) on 08. Touch down normal, one application of bakes then
nothing. Gust knocks us slightly sideways and aircraft continues on 08
trajectory despite 30% drift on greasy top soil after no rain for 10
weeks and sudden shower. Try brakes, nothing, now seriously sideways and
hedge approaching.... Reach across to P2 yoke and hit that brake.
Nothing!!!! Shit leaps to mind!!!!
Still doing 50+kph. Look at son and tell him we're going though the
fence now less than 100 yards away and to hang on. No steering, no
brakes, no hope...
As we slowly slide though through 60% to direction of travel and I
expect the gear to collapse, my old motor bike racing instincts awake.
50 yards from the fence I kick in full left rudder and give it max
power. Yippee. a 90 degree turn and reverse thrust. Power off. We settle
20 - 30 yards from the fence. Disaster averted. Only worked once or
twice on a motocross bike but I was always told "at least you get a
second chance". It's true!
Eaglescott radio then inform I am a Lucky B******
Run up at 50% for 2 minutes (pointing slightly up hill sand in LONG
grass) and minimal brakes return as I get back to 2 Bar. Taxi "VERY
SLOWLY" to parking spot, shut down. Put gear to neutral. Pressure in
main tank drops to 1/2 Bar! Nothing from snot valve.
Hindsight is wonderful. I passed a perfectly useable 2000m hard runway
(Exeter) and should have gone back there. NO question. I knew I had a
problem and I screwed up. Go for runway length and services. NOT where
your car is parked X;{
Any other thoughts on the situation, my behavior or the problem?
One thing is for sure. When I go out tomorrow, I fully expect the
landing gear problem to be an unsecured and un safety wired replaced
line to the nose gear in Hungary. I hope not but it IS what I expect. So
clearly I have no faith in the HA guys. If we can't get good maintenance
on these 18T's in the UK we are in serious trouble! Will let you know
what I find but it might be handy to know what you all think I should
look for too.
PS. Mark, Richard and Rob. Will be calling you all in the morning for
pointers obviously. Thank GOD it didn't happen at Branscombe! I could
easily have slid into =A33+m worth of WWII history!
BTW. The Mustang display was killer. However, the Hurricane display
proved it could clearly out turn them and would have had the best shot.
Just added this in order to be suitably controversial for this highly
esteemed and US dominated list ;-) Pictures available for anyone who
wants them or can post them.

Dennis,
Ok thats all well and fine but. the book says to add oil every 100 hours or so..
How do you get the oil there??? It wont make it thru the system by shooting
it in with the scuba set up. I will assume that oil needs to be shot into both
fittings (top and bottom) for this to be achieved. Is this correct? I planned
on resealing both cylinders anyway but was more concerned with getting the oil
there to keep from trashing the new seals. Apparently sitting damages the seals.
Hopefully the cylinders are not built like the rest of the plane. LOL

Are you using an ethanol type fuel ? Ethanol will dissolve fiberglass
according to a marine industry study . Vinal ( spelling?) ester
fiberglass tanks do not seem to have this problem.

Bruce,
Have you checked you fuel filter screen. If your tanks are breaking
down, your filter should be clogged with fiberglass if this is the case.
That is a quick look that will not cost you an arm and a leg.

Flir,
Most of us put the machine oil in the main and Aux air tank when we take
the tank off to dry it out/drain it during our annuals. If it is at the 5
yr time frame then the tanks are sent for hydro testing. With the actuators
off, you can instill machine oil in the cylinders but that only helps the
individual unit mainly.
I am not the expert on this, but Dennis, Doug Sapp, Carl Hayes, and Cliff
Coy to name a few here are the maintance garu's! I learn by watch
Dennis...sometimes not to well.
Hope that helps some. By the way, does the me262pilot in your email address
mean that you also fly the Messerschmitt 262 or Me to sick to pilot? Heey
Heey. Assuming Me 262 mean the jet..what's it like to fly?

Returning to magneto coils, defects with symptoms

--> Yak-List message posted by: "david stroud" <dstroud@storm.ca>
I'm saddened to announce the death of our local EAA Chapter 245
President in an accident at Oshkosh this past Sunday. Gary Palmer,
63, of Ottawa Ontario was a passenger in an RV homebuilt piloted
by our local RAA President, Bill Reed. While holding on the ground
for instructions, they were overtaken by a Grumman Avenger. Gary
died of prop strike injuries on the scene and Bill escaped unscathed.
Take care lads...this is supposed to be fun.

Hi all;
I'm going to put a Russian altimeter in the rear position of the SU-29, just gotta
have meters... I now have the altimeter but need the attach ring (?) This
is a ring that apparently slips on from the back side and catches on a lip on
the face side. It has the needed screw holes/fasteners to affix the altimeter
to the panel. Anybody got some? Please and thank you.

You can add oil to both sides of the actuators by removing the both the UP
and DOWN flexible lines and putting machine oil in the flexible line and
refitting it to the actuator.

| Subject: | Matronics Email List Web Server Upgrade Tonight... |
--> Yak-List message posted by: Matt Dralle <dralle@matronics.com>
Dear Listers,
This evening I will be upgrading the Matronics Web Server hardware to a new Quad-processor
2.8Ghz Xeon system (yes, 4-physical CPUs!) with an Ultra 320 SCSI
Raid 5 disk system and 5GB of DDR2 RAM.
As with the older system, the new system will be running the latest version of
Redhat Linux. Most of the software configuration work is already done for the
migration, but I still have to sync all of the archive and forum data from the
old system to the new system. I am anticipating about 2 to 3 hours of downtime
for me to fully make the transition, although it could be considerable less
if everything goes according to plan.
The Matronics Webserver will be *UNavailable* from the Internet during the work,
and you will receive a time-out if you try to connect during the upgrade.
Email List Distribution will be *available* during the upgrade of the Web Server,
and List message distribution will function as normal.
This represents a significant performance upgrade for the Matronics Web Server
and you should notice nicely improved searching and surfing performance following
the upgrade!
Best regards,
Matt Dralle
