| Subject: | M14P Baffle / Felt Seal |
Spending winter making repairs to my SP55. While replacing several baffle segments,
I noticed that I am missing the felt seal material on all cylinders. Tried
Jill and Doug, no stock. Can anyone tell me the importance of having these
felt pieces in place? Anyone have one on the shelf that I can copy?
Regards,
Francis Butler

Jay;
1400 Kg. is the =9CNormal flying weight=9D per the Tech.
Specs. manual. This has been accepted by Canadian authorities as the
MAUW.
I think the UK and the US are the same though someone else should
correct if not so.
As to your fuel imbalance I can say only of course. The vent system is
not the problem! But I have said it before and no one seems interested.

Subject: Yak-List: Nanchang MAUW
Hi all...
anyone no of an official MAUW for the Nanchang?
The reason I ask is that we have just installed the 120 litre bladder
tanks and with 2 people, 240 litres of fuel and, say, 20kg of bags we
come out at about 1530 kg (3366 lb)
When the first CJ came into New Zealand they were unable to find a
published MAUW and chose 1400 kg as this was the cut-off point for the
cheapest landing fees and so forth... nothing to do with the aircraft so
to speak!
Incidentally, to flog a dead horse, after revising the fuel vent system
as per the instructions (inclulding new vent lines from the tanks) and
alternating the collector tank flapper valves from one side to the
other, the blasted thing still feeds from the LH tank first!
Must be the rigging/balance!
Cheers, Jay
New Zealand

Hahaha... if we made every person who comes to the Yak List complaining abo
ut fuel-feed imbalance buy a beer for thinking it's the venting... we'd all
be alcoholics by now. :-)

You are right Walt.
For the UK CAA, the MTOW for the Nanchang is also 1400 kg :
http://www.caa.co.uk/application.aspx?catid=60&pagetype=65&appid=1&mode=summary&aircrafttype=Nanchang
For instance, this one based in Belgium, registered G-CJSA :
http://www.caa.co.uk/application.aspx?catid=60&pagetype=65&appid=1&mode=detail&aircrafttype=Nanchang&dataindex=4
http://www.abpic.co.uk/popup.php?q=1304573
For the Yak-52 :
http://www.caa.co.uk/application.aspx?catid=60&pagetype=65&appid=1&mode=summary&aircrafttype=Yak-52
the UK Civil Aviation Authority states a MTOW of 1315 kg or 1415 kg.
MTOW 1315 kg for the standard Yak-52, for instance this one also based in Belgium,
registerd G-CBSR :
http://www.caa.co.uk/application.aspx?catid=60&pagetype=65&appid=1&mode=detail&aircrafttype=Yak-52&dataindex=16
MTOW 1415 kg for Yak-52 equipped with Long Range fuel tanks (2 x 80l), e.g. :
http://www.caa.co.uk/application.aspx?catid=60&pagetype=65&appid=1&mode=detail&aircrafttype=Yak-52&dataindex=17

I have three rather old Russian screw jacks for my Yak. One works fine but
the other two get to a certain height and do not want to move further. I
used the bigger hamer principle and put a section of pipe on the handle for
leverage. That idea was only partially successful until the lower shim/wa
sher/bearing surface buckled up. I assume these washers/bearings are shot
and need replaced as I have throughly greased and oiled the srew as best I
can. The design of the jacks look to be a permanently installed jack colla
r/bearings. There is an overhang on the top of the collar surround on the
tripod which prevents removal of the jack stem and collar with the bearing
s. Looks like I may have to cut the welds=2C remove and reweld once parts
replaced. I would then need a source of parts to get new sleeve/washer/fla
t bearing parts. Can anyone enlighten me on the above and parts availabili
ty. A google search on these jacks has been fruitless. Alternatively are t
here other jacks that work with the Dennis Savarese jack points for the Yak
52? Jim Shaner

Jim,
The jack points are nothing special. Just plain old jack points. Since
you have a 52TD, you won't need to worry about the front jack point. I
will find the web site of the jacks I have used for years and send it to
you off-list.

Two questions
1. thermocouple position and common problems with cylinder head
temperature gauge. Previously has worked flawlessly, now I have
initially
20=B0 drop in numbers, and occasionally the needle swings a little. I
assume I
have a high resistance joint somewhere, back of the dial is OK, so
advice as
to the position of thermocouple, type and replacement gear before I
start
pulling things apart
2. fuel tank gauges in my 18 T have worked beautifully up until
recently. We calibrated the gauges, filling the fuel from absolutely
dead
empty right through to 360 L total as I have auxiliary tanks. Given the
die
he drill in the wing, we read 180 L total, but actually have about 240 L
on
board. I now have no response, as the fuel comes down to a known level,
that
is clearly about 40 L remaining on the inboard tank. Any suggestions?
