I also am inclined to think that it was carburettor icing. The block of ice
in the carburettor could jam the throttle.
Carburettor icing can happen quite often here in Northern Europe, when the
weather is very moist and temperatures around 5 degrees centigrades. We
don't have the problem when it's really freezing, of course.

Hi Didier
We have struck the same thing here in New Zealand during our cooler weather
when after landing the throttle will not move. This can happen when the carb
inlet temp is below 3' .
I have struck it several times and after closing the carb inlet it cures
the problem almost immediately. Often on cold days I will set it at about
half position, If the inlet temp is kept above 3" it does not stick. Have
only ever had it happen either on short finals or after landing.

Mark,
I must say that the thing that happened seems more mechanical than ice. But
I will examine all possibilities.
The only thing I know is that I did not dreamed the problem. I was with a
friend owner of a 52. He is a comercial pilot. And both of us could see that
the motor did not want to go under 50% even if I pushed hard on the throtle
lever. We even tried to check the pitch (going to coarse and back to
fine)...
After turning off the motor and refueling. At the next start everything came
back to normal. But I did not tried the carb heat (was off) and I did not
looked closely to the throtle lever. Was it completely down or was it
blocked I am not sure.

Many of the Yak 52's do not have flap rod covers inside the cockpit.
All 52's originally had the same type covers the Yak 52W and TW have.
These openings inside the fuselage are a prime location for air leaks
and of course CO as well.
You can help eliminate the cold air billowing into the rear cockpit and
some of the CO too by making a soft cover to slide over the horizontal
flap rods and affixing the soft cover to the inside of the fuselage.
Use a scrap piece of leather or soft vinyl and cut out a "patch" that
will fit over the opening on the inside of the fuselage. Cut a slot on
one end of the patch so it will slide over the flap rod. Then cut a
"star" pattern where the flap rod slides through the patch. Glue the
patch to the inside of the fuselage with contact cement.
It's not perfect, but it sure does reduce the cold air tremendously and
I'm sure it also helps to reduce the CO in the cockpit.

FWIW; The thread on smoke got my curiosity up so when the chance to
fly
came up today I took a pocket CO meter along. On the ground, canopy
closed 14 ppm, flying w/ canopy closed "0". Then to change the
airflow
I did some mostly positive acro ( loops & cubans) and it went up to 22
ppm. These are lower than I remember but some time back we put a
metal
FOD cover in the tail which would block a lot of the airflow out of
the
tail. That probably helped keep the CO out. With the ram air
ventilation of the Yak, closing the open space on the TOP of the
elevator bell crank might do more to obtain positive cabin pressure
than
trying to seal cockpit leaks. I am not aware of anyone that has done
this.

In the September issue of Sport Aviation (EAA magazine) there was an
excellent article on page 80 titled "Carburetor Icing Prevention;
Special Airworthiness Information Bulletin". It was written by Peter L.
Rouse, Aerospace Engineer, of the FAA's Special Airplane Directorate.
In the article there is a graph which shows the probability of carb
icing for various temperatures and relative humidity conditions. What
stands out is the very small area in the graph where a pressure type
carburetor is "susceptible" to icing.
The article says:
To recognize carburetor icing, the warning signs are;
- A drop in rpm in fixed-pitch propeller airplanes
- A drop in manifold pressure in constant-speed propeller airplanes
- In both types, usually there will be rough engine operation
If you don't have a copy of the magazine, do try to get it or at least
have someone copy the article for you.

First you will need the new, hard copy registration showing the new,
registered owner. Next, complete the FAA Form 8130-6 which you can
download. Make a copy of the new registration. Then send the copy of
the new registration, your old Special Airworthiness Certificate, a copy
of your engine and airplane log books showing the current annual
condition inspection sign-offs and an annual Schedule of Events (Program
letter) and mail it to your local FSDO telling them you recently
purchased this aircraft and would like to have issued the new Special
Airworthiness Certificate and new Operating Limitations.
It might be a good idea to call the local FSDO first and talk with an
Inspector who is familiar with issuing new OL's and Special
Airworthiness Certificates for Experimental Exhibition Group III, under
800 horsepower airplanes.
Call me if you need help.

| Subject: | riveting, bolting, question? |
I would like to remove the pull out this tray and put in another u channel cross
brace so that I can skin the whole section with a sheet of aluminum rather that
just the slide out tray. I will mount a smoke tank as well as the battery
and one inverter (the other is coming out)
The sheet will only go as far as the current brace in the fore ground so that I
don't impede access to my air tank.
Thoughts on the pitfalls of this plan. Also would it be OK to pop rivet the new
u channel with the L-brackets or should I use screws. Same question for the sheet
aluminum base.
I'm afraid I have only done pop riveting.

Kelly,
Just went through this process with our local FSDO, culminating with
an inspection at my hanger last Thursday. The steps are just as Dennis
outlined.
I would emphasize that you need to contact your local FSDO early and
work with them. There have been some changes in the limitations
they'll assign compared to what they were doing several years ago, so
expect your new limitations to be different. Our FSDO assigns
airworthiness inspectors to individual aircraft, so there has always
one person that I have been working with. Overall, a very pleasant
process and I found my inspector to be quite helpful.
You may also want to write to Oklahoma City and ask to have copies of
everything that they have on your aircraft. There is a minimal fee for
this and it is a routine practice. This may allow you some additional
insights into your purchase.
Best,
Warren Hill

Although I have used this "fix" on several M14 carburetors, Termikas has
found an even better solution. The problem has always been the
accelerator pump jet diameter being too large, including even the
smallest jet which is .9 mm. What Termikas has found out (and I have
done this on my engine) is to remove the jet in the accelerator pump at
the TOP of the chamber just above the one shown in .pdf file pictures.
See attached. The jet at the top is always .6 mm and it seems that
placing the larger jet at the top of the accelerator pump does not have
any negative operational results. It does remove the hesitation and the
accelerator pump remains in full operation.

better. The best thing it does is it gets all the fuel out of the cockpi

I have and love it.- No more wobbling, priming and starting is easier. In
case of a pump failure, with a flick of a switch, I have fuel and can conc
entrate on flying the plane. Great mod if done properly.- Need-correct
hose size, pump with correct flow rate and if using it to prime, check valv

Yes.
Did this mod on my former SU-29 and my current Yak 55M. Does a great

| Subject: | new operating limitations |
Concur with Dennis in every way.
Just my 2 cents:
I just went through this myself on a UTVA-66. One thing I learned was
to try to know more than the FAA about the subject. Not in a "know it
all" attempt,..... but so that when they added NEW material to the old
Operating Limitations, I could nicely ask them: "Sir, isn't it wrong to
add more to the Operating Limitations than were on the older existing
ones?" By the way ... They are NOT supposed to do that!
What they had done was to change the WORDING of the new Operating
Limitations to put them in line with a new FAA directive that requires
them to be listed in a different order. They knew all about that, but
required me to submit to THEM the material that allows the removal of
the 300 mile limitation.
It is very clear that a new aircraft inspection is NOT required.
However, some FSDO's seem to want to do that. I wouldn't make an issue
out of that, but you could if you really wanted to. That aside, the new
limitations that they issue should only be REWORDED and in NO WAY MORE
RESTRICTIVE! This is important to understand, because if you ACCEPT new
limitations that have wording that ADDS further restrictions, it is much
harder to get them off later. MUCH harder.
As an example, my FSDO added wording that said: "NO NIGHT FLYING",
instead of "NO NIGHT FLYING UNLESS PROPERLY EQUIPPED".
Along with about four other little "pen and ink" errors that could have
really added up to a disaster for me had I not caught them! Compare the
old Op-Limits to the NEW Op-Limits... Word for word. CAREFULLY. If
they have ADDED new limitations, you must REFUSE to accept them.
Politely of course. Also make darn sure that the DATE on the Operating
Limitations and your Special Airworthiness Certificate MATCH~! Someone
else posted a notice on that earlier and it happened to me as well.

Kelly,
Just went through this process with our local FSDO, culminating with an
inspection at my hanger last Thursday. The steps are just as Dennis
outlined.
I would emphasize that you need to contact your local FSDO early and
work with them. There have been some changes in the limitations they'll
assign compared to what they were doing several years ago, so expect
your new limitations to be different. Our FSDO assigns airworthiness
inspectors to individual aircraft, so there has always one person that I
have been working with. Overall, a very pleasant process and I found my
inspector to be quite helpful.
You may also want to write to Oklahoma City and ask to have copies of
everything that they have on your aircraft. There is a minimal fee for
this and it is a routine practice. This may allow you some additional
insights into your purchase.
Best,
Warren Hill

| Subject: | engine shutter vane adjustment |
The engine control knob for my shutter vanes does not feel right. Almost like I'm
working against a bad spring. It's hard to turn. I can really only get full
open or full closed. Any where else but the exact middle position and vanes move
open or closed on their own. They usually won't stay in the mid position either.
(knob spins) Looked at the linkage and don't see any issues. I know there
are detents on the knob that should allow it to stay in place at many different
settings but mine will not hold.
Ideas?
Thanks

| Subject: | Digital Tach Update |
Fellow Yak-listers:
Here is the word. Order them thru Doug Sapp.
We have just received word that the T-30 tachometer works with the
M-14 from our launch customer (a Wilga). We are making a minor
firmware update to make it easy to set up with the M-14 and other
engines with an odd number of cylinders.
We expect to begin shipment to M-14 customers during the week of 10/26.
Thanks for your interest and patience.

| Subject: | Re: riveting, bolting, question? |
Keith,In my opinion it would add time to the job and the finished job would
be less than professional if you attempt to do the task you describe using
nuts and bolts, or heaven forbid---ARGH!, pop rivets, it would also add
time/cost to inspections or any other reason which might cause you to remove
it in the future. For the cleanest most professional job you should
consider installing it in riveted assemblies, those assemblies should then
be installed in the aircraft with nut plates thus making the entire
installation easily removable in a short amount of time. This might seem a
bit more trouble up front but it will save you a bunch of money later if you
or whoever is doing your condition inspection needs to remove them.
Have you considered placing the battery under the surface of the baggage
compartment?? The newer style sealed batteries make this possible, and the
savings in space is in my opinion worth while. The inverter can be mounted
most anywhere, seems a waste of space to put it in the area where you could
pack baggage. Who knows--- you may have to bring the beer next time.
Riveting is not hard to do/learn, buy yourself some tools, get someone to
look over your shoulder and go at it.

| Subject: | Re: riveting, bolting, question? |
Thanks Doug,
I'm pretty picky so I wouldn't have used pop rivets but it sure would be nice to
learn how to really rivet.
I like your idea. I actually have a sealed battery and if you notice, a nice baggage
compartment as well (the rear wall is in the picture) which holds a tremendous
amount of beer.
It makes total sense to remove the floor and look for a spot underneath for the
battery tray and inverter. I never even thought about that!
Have you ever seen the inverter mounted on that frame between the two cockpits
where some of the other electrical gear is located?
I could then use that current sliding tray set up for the smoke tank and pump.

Keith,
I agree with every thing Doug said and would add that future inspections and repairs
or modifications
are easily done when you can unbolt and remove these assemblies.You might consider
cherry rivets from Aircraft Spruce
for thesmaller assemblies .

| Subject: | Re: M14P Jet Mod |
When I got my engine new direct from Aerostar, it stumbled badly when
advancing the throttle quickly. Scare the popo out me sometimes.
The engine came with a whole selection of jets as part of the parts kit you
get with a new engine. I put in the smallest one I could fine. I really
don't know the size. The engine stopped its stumbling and has been fine
now for 1,500 plus hours.
I've heard of both the plugging and using the .6 mm jet. From all
accounts, both seem to work OK.

Yes.
Did this mod on my former SU-29 and my current Yak 55M. Does a great
deal to reduce "stumbling" if power needs to be abruptly increased, and
seems to reduce loading up while taxiing also, although that is much
less pronounced.
I've been very happy with this mod.
