Hi, my name is Elmar Hegenauer and I am in the process of
purchasing a Nanchang CJ-6A (I am still waiting for better
weather conditions to bring it to Vancouver Island).
Is there any kind of an automatic fire extinguisher system for
the engine compartment available (e.g. those systems used
in power boats)?
Thank you in advance. Cheers Elmar
I've never heard of one on the CJs and have never heard of a CJ engine fire.
They just as rare on these engines as US spam cans. Don't mean it can't
happen.
I would not put any faith in automatic system. If I were to install a fire
extinguisher system it would be manually operated and independent of the
electrical system.
The B-24 I fly for the Collings foundation went though the war without a
fire suppression system, however one was put on during its 3 million dollar
restoration 15 years ago. Quite frankly, the only thing its done is make the
insurance companies a little more comfortable and an engine change more
complicated.

Yaksters
On the advice of a local machinist, I'm considering installation of what
is known as "ALUMINUM BRONZE" bushings in all of the joints that make up
the shimmy damper on my 52. The machinist says that the new "ALUMINUM
BRONZE" material is much stronger and longer lasting than the
traditional sintered bronze bushings. Before I give him the go ahead I'd
like to get any opinions on the use of this material for bushings on an
aircraft.
Thanks in advance!

Pappy and anyone else doing conversions like this, try downloading this free
software:
Convert version 4.10
www.joshmadison.com/software/convert/download.asp
If that does not work, just step through the downloading process manually by
going to:
www.joshmadison.com
I think EVERYONE will find this software VERY useful. Especially given the
units of measurement used in the foreign aircraft that we fly.

Great news.
To the best of my knowledge the Yaks / CJs made it through all of January without
a single accident / incident.
If this turns out to be true, its the first month we've gone without an accident
since at least May of 2004.
How did it happen? (Half the country snowed in?)
A few questions for my underwriter who is watching our progress.
1) Did anyone find the review of systems helpful?
2) Have you modified your pattern procedure or cockpit habits?
3) Found mechanical problems that have now been addressed?
4) Have a better knowledge of the Abnormal and Emergency procedures and Systems??
We're encouraging (Strongly) that everyone do their BFR in a Yak or CJ if you fly
one.
Preferably with an RPA approved instructor using the RPA syllabus.
Submit that paperwork with your insurance renewal . . .
I appreciate everyone's effort.

To Pappy and Elmar. Re Fire extinguishing systems:
Any fire ext sys you put on a radial engine has to have a means
of closing in zones 2, 3 and 4. Characteristically, radials have no way
to close in zone 1, which encompasses the nose case. But what do you have
to burn out there in zone 1? More than you might think on some big
radials with a magnesium nose case, You probably haven't seen a real
engine fire which defies extinguishing until you've seen a magnesium
fire from a runaway prop in the process of seizing up or flying off the
engine.. It is an illuminating experience which is best viewed on a dark
night for effect. Further, there isn't much time to get the beast on the
ground before it burns through the tin and into the fuel tanks followed
by wing failure.
Pappy, If you get a zone 1 fire on your B-24, you may recall
from some earlier training on a different equipment, the first priority
is to Feather because you don't have extinguishing to zone 1 and the only
way to extinguish is to feather and dive to blow it out. Feathering is
best accomplished at a lower IAS which preceeds the dive.
Elmar, I don't know if your CJ has a magnesium nose case, but if
you have retained the cooling gills on the airplane you DO have a means
of enclosing zone 1. The purpose of enclosure is to keep the
extinguishing agent from being evacuated before it can be effective The
greatest risk of fire in your CJ comes from the fluid lines in zone 2.
Check them frequently for brittleness and stiffness as well as integrity
of hose to fitting.
Watch for signs of SEEPAGE both through the hose and at the fittings.
Contrary to general knowledge, there have been about 5 instances of
engine fires in the YAK and CJ series of airplanes. Most of these
occurrences are due to failure to change the hoses at proper intervals
and/or use of wrong ( spelled AMERICAN ) size hoses with Russian
fittings. ( "Looks right"aint good enough here ). Manufacturer's
recommendation
on the YAK series is all hoses changed every 5 years. Brake lines too!
Elmar, Your zone 3 vulnerability ( if CJ is like YAKs } includes
the fuel tank area forward of the cockpit, Does your airplane have a
stainless steele firewall by way of original manufacture or later
modification? In the YAKS this gives you a little more time to get the
fire out, or put it on the ground . Don't be too choosey as to WHERE, you
don,t have the luxury of TIME.
One thing more, check the band clamps securing the flexible
exhaust manifolds. With rust comes weakness and porosity. A hole or
separation in the exhaust assy. can act as a blow torch on a fuel or oil
line. Look for signs of discoloration around the exhaust assy. and
related
area. You can't see enough with the cowling closed all the time, Take
the tin off frequently!
Best Wishes and Safe Flying

Hi Cliff,
thank you very much for your informative
and professional email, very much appreciated.
Since I have read your opinion I have to think the
whole thing over again.
Thank you.

Luke,
You and KJ Kimball screwed up the calculation of Newton to pound. Your
error was using the gravitational constant of 9.8 m/s squared.
A Newton is defined as the amount of force which will accelerate 1 Kg to a
speed of 1 meter/second in one second. Notable points are that Kg is mass
(not weight). A Kg on the earth is still a Kg on the moon or in orbit.
A Newton is a Newton on the moon or in space. Neither the Kg or Newton have
anything to do with gravity or the lack thereof.
Another notable point is that Newtons can be converted to pounds, where
kilograms is not technically convertable to pounds because one is a unit of
mass and the other a unit of force. This is only a technical argument since
nearly all of us spend all of our time near the surface of the earth where 1
Kg mass at rest presents a force of 2.204 pounds to the object supporting it
due to gravity.

Pappy,
Bulletin boards are a wonderful place to get opinions and a less wonderful
place to get technical information. I hope you didn't torque anything based
on KJ or Luke's Newton.
1 newton = 0.2248 pounds
Don't forget to convert the meters to feet in your torque calcuation.

Why don't you just buy a torque wrench marked in both foot-lbs and newton-meters.

Ron;
Great post on the definition of Newton, mass and force. The concepts of this
has pretty much baffled me for years. This helped though whether my few
remaining brain cells can hang on to it is another question.
For Pappy;
If you just want to how hard to pull on the wrench here are the
conversions ----
Newton/Meters (N.M) X 8.850 = lb/inch
lb/inch X 0.113 = N.M
N.M X 0.737 = lb/ft
lb/ft X 1.356 = N.M
Cheers
