We now have the Russian parachute manual translated, if you need it.

The manual might be interesting reading, but doesn't alter the fact that
Russian/Chinese chutes have no TSO, nor NAF/AAF/AN drawing number as
required by FAR 91.307 (e) for them to be sat upon in a flying airplane in
the US.
A foreiner could perhaps wear one IAW FAR 105.49.

I have a YAK52 and use a Scott air bottle to refill the air system. Does
anyone know what the fitting that connects to the Scott bottle is or where
to get one. I have the one that is on my hose, but I need another one for my
Scuba Compressor to refill the bottles. No one has them or knows what size
they are or where to look for one. The Fire Department has one, but only
knows that it came with the compressor. Any help is appreciated.

The March "Annual Safety Issue" of Warbirds , in addition to the incomplete
article on Y52s which was thoroughly discussed here, also has a piece written
by Dave Marshall entitled "Wing Fatigue." I found it compelling. The thrust
of Marshall's argument is that metal, i.e., a wing, like a paper clip, can
only be flexed so much before it fails irrespective of G limits. All wings have
a "fatigue life expenditure" (FLE) or a "calculated fatigue life available."
Marshall goes on to describe a military aircraft that was operating well
within G limits when its wings failed. As warbird operators, he cautions us think
carefully about the history or our aircraft. Which brings me to my 1968,
4000+ hour CJ about which I know bloody little. Apart from the additional
revelation that it had some 21,000 landings (every one a greaser) when it came
to
our shores, the Chinese were not forthcoming about the rest of its history.
Such, I believe, is largely the case with all of our CJs.
Now, I'm aware of Mr. Bushi's comment that he was unaware of any structural
failure in a CJ. As a rank layman, however, I would like to hear from those
among us more knowledgeable than I on this subject. More to the point, as an
ACM beginner should I routinely be bending this thing around at 4 to 5 Gs?
Thanks, Blitz

Mike,
Sorry to hear that but understand. 'Tis the life of an aviator -- never
quite having the freedom to fly when you want to fly.
I had one guy call me about where to stay as he may come out from AZ. I'll
forward this to him, plus post it on the yaklist. Maybe they can contact you
direct.
We'll miss ya.

I use a Scott bottle as well. Most scuba places have the fitting to the
Scott bottle as well and should be able to point you in the right direction
to get the connector. Also, when I originally went to the scott bottle
system, I got the connector for the regulator from a gas place that had
fittings for practically any gas tank system (But that was 5 years ago
somewhere in IL :-) )... you could try your local nitrogen/oxygen/etc.
place.

Aubry;
Rig a Schrader Valve from Aircraft Spruce and Specialty
www.aircraftspruce.com (Also known as a STRUT VALVE P/N 4361S $36.70)
into your air fill port. These also work great for your
struts......oddly enough. Then get a GOOSENECK HOSE COUPLING P/N
06-11700 $15.000. Fit that to the hose you're going to get made that
goes to the "K" bottle of high pressure air. Go to Praxair or another
bottled gas supplier and get a "K" bottle of compressed air, the bottles
are usually pressurized around 2300psi. This makes your system
compatible with most others and elimiantes bastardized configurations
like you get with scuba bottles. Works like a charm........also it's
more likely you will be able to get pressurized air when you run out
while in upper Slabovia.

Ron,
Be careful, if you fly a Yak or CJ it is not Standard
Category, but legal to fly; so is the "Russian chute".
Recheck the last part of that sentence in the reg and
it is clear why the chute is OK. Also it helps that
the plane is designed to have a chute at all times.
Is your homemade seat cushion TSO'ed?
Zeman
========
The manual might be interesting reading, but doesn't
alter the fact that
Russian/Chinese chutes have no TSO, nor NAF/AAF/AN
drawing number as
required by FAR 91.307 (e) for them to be sat upon in
a flying airplane in
the US.
A foreiner could perhaps wear one IAW FAR 105.49.

The B-52 was made over 50 years ago. It too has a design fatigue life.
Why is it still flying? Look how many 172's are still flying.
Manufacturers typically use conservative numbers in their calculations
of wing fatigue life so as not to get sued when a wing breaks. They use
figures derived from calculations based on maximum g's imposed on the
airframe every single flight. They have no other standard for comparison
that might represent typical flight situations. In other words, what is
typical flight? Trust me, there is no standard by which to base their
calculations. No one can answer that question so the manufacturers play
it safe with their published numbers. Maximum G calculations used for
every single flight in determining fatigue life are not very realistic
BUT it does keep manufacturers from getting sued. Regrettably, real
numbers are usually derived from actual incidences of structural
failures. When the numbers reach statistical significance is when the
FAA usually acts.
