| Subject: | Magneto Maintenance |
For those who are new to maintaining their M-14 or Huosai mags, I authored a How-to
document, with pictures. You can find it on the RPA/Store/Manuals page.
Magneto coils do age and degrade, but NOT as often as other magneto/ignition maladies.
Now that Doug Sapp is getting a supply of replacement coils made, I expect
to keep these beasties firing for a long time to come..

Interestingly, after a certain amount of battle, we have been able to get
formal approval for the use of the Savaresse Plug Conversions with EASA (the
overall European Aviation Controller) for "certificated aircraft" like
Sukhois and Yak-18T, and from the UK CAA for non-certificated aircraft
Yak-18A/50/52.

Hi all,
just for information. Today it was possible to reproduce the failure on a ground
run after a few minutes while the engine was warmed up.
As most of you supposed, its a bad coil in magneto #2.
Thanks again.
Stefan

Glad you did not have to fly her to reproduce it. Life's to short for to
many sphincter tightening experiences.

Hi Stefan,
you may have one faulty coil in the mag, but white spark plugs are no symptom of
a shot coil - the contrary. As you said you are running the Yak on part auto
fuel. And we had real trouble with that in hot weather - no take-off at 100 %
power possible in the 18 T . A fill-up with avgas helped, no other actions required.
So the real problem was vapour bubbles in the fuel pump at high rpm.
As this pump is not particularly good in sucking we added an electric pump in
front of the service tank to feed the engine-driven pump. This Pierburg pump should
deliver ~100 liters per hour at 0,5 bar nominally, but was at its limit
in times, so we added another one for safety and since we never had a drop in
fuel pressure to critical limits when using pure auto fuel for some years now.
Youd be lucky to find avgas at 10 Dollars per gallon these days in our continent
and this wont be getting better we feel ...
So it

The electric pump is an interesting solution.
I am planning to change to unleaded 98 or 95 but have heard about potential
problems of vapor lock and also prooblems tha could occur by mixing 100LL
with unleaded.
Could we have more details on the installation of an electric pump on your
plane..what kind of pump , where to put it , what kind of connections
etc....
Even pictures could be nice.
We are experiencing a big lack of 100LL at the moment in France.
best regards
Didier

| Subject: | CJ6A serial numbers |
Hope some one out there can help me.
I would like to find my serial number on a Nanchang list that specifically states
the aircraft is a CJ6A and not the generic CJ6 and also gives the date of manufacture.
Does such a list exist? If so please let me know so that I may access it.
Thanks very much.
