Actually, BJ put his NACA duct just below and on the right side of the front
canopy.

| Subject: | Funnel -Type Oil Tube |
Hi All!
I recently found a large crack in the Funnel-type Oil Tube (Part #H2-6204-00) on
the flange where it attached to the oil pump. When we pulled the unit off we
discovered that the crack was about halfway around the tube, and that it had
been repaired at least once before.
The unit was unsupported at the oil hose end, which surprised me as it's a fairly
big piece. Had anyone developed a bracket support for this unit to avoid this
very messy situation from occuring again?
Thanks!
Mike

It was a Sukhoi-31. One of the best ones I have ever seen. Engine mods
put it easily over 400 HP. Probably around 430 or so. I'm just glad he
is alive, although he is in significant pain from the burns. Sergei
walked out of the hospital because it "costs too much". He has had a
bad year. My heart goes out to him.

| Subject: | Yak 55M Aileron Bearings |
During preflight I noticed the outboard aileron on my Yak55M wiggled
fore/aft. I check it regularly, so this is something new. The left
aileron is solid. The aileron bracket to the wing is tight, so the
movement is within the aileron hinge or bearing.
Is this something that common with the Yaks? I remember seeing an
email about that before, but searching the archives, I couldn't find.
Thanks,
John

Doc, thanks for the mini lesson in physiology!! I forgot about the tenacity
CO has for hemoglobin.
So it seems as though you all need to buy air conditioned Beech Bonanzas.
Problem solved. No sweating and no CO!!
My other solution is to put exhaust stacks on the Yak just like our
18-wheeler friends have. Put that darn exhaust way up in the air. Oh,
don't forget your chrome flapper for the top so water doesn't get in.

Ahhhh,,,breath CO like a man! Don't forget the CO succumbee was a CJ driver!
I 'm looking for the chromed flex pipe for the wrap around Stutz Bearcat
effect on the 50 myself.
Air conditioned Bonanzas are for trophy wives that hate wearing a headseat
because it crushes their hairdoos and sweat might run their makeup.

| Subject: | Re: Yak 55M Aileron Bearings |
Attention to all the exposed bearings in the Yak is very important. That
is, they should be cleaned and lubricated regularly. On the 52, the inboard
aileron bearing is always the most difficult to clean and lubricate. But it
must be done regularly. Bearings that are exposed to the elements, like the
outboard aileron bearing you mentioned are particularly prone to picking up
grit and grime. This of course destroys the bearings. I'm not sure about
the 55M outboard aileron bearing, but the outboard aileron bearing on the 52
is unique and expensive compared to the very common 19mm OD x 6 mm (ID) x 6
mm (W) self aligning bearings.

The ass end of my airplane is up in the air so I will look at what it would take
to prevent CO from coming in. Maybe a cover for the bulkhead just inside the
tailwheel inspection panel? Maybe a boot over the thing? Maybe some sort of external
"device" that diverts air away. Something small as to not affect the handling
qualities of the airplane.
