Wanted: Oxygen Cylinder For DG-400
Terry Edmonds
fit the compartment in the DG-400 (and probably other DG sailplanes).
Apparently the compartment was sized to fit a german made cylinder.I
would like to hear from anyone who has one of these cylinders they
would be willing to sell. The compartment size is 10.5 cm diameter and
50 cm long.

worked a deal to get a bottle from them that was a bit smaller than the
medical E that's a bit too big. If Tim can't help, let me know.
I think this also is the case for early LS models too.

The German bottles generally don't have the right certifications
stamped on them for the USA, and suppliers won't refill or test them.
You have to fill them yourself or find someone that doesn't bother to
check. You might try asking on the DG group about this - a listing for
it is on the www.motorglider.org website.
Another possibility is the lightweight, fiber wound bottles sold by
Mountain High (www.mountainhighoxygen.com), which might be smaller in
diameter than the conventional metal bottles.

It may happen that a foreign registered airplane is coming
into the US with an oxygen system installed. Do you think
it wouldn't be refilled when needed?
I am looking myself for an oxy cylinder which could fit
into my German sized bottle compartment (dia 100mm,
lengt up to 500mm approx) Any idea?
Thanks
Michael

It will probably get refilled at most gliderports and airports, as
few check very carefully. However, if the aircraft has a US
registration, one thing that will be looked at during an annual
inspection is whether the cylinder has been hydrotested within
the past 5 years. The hydrotesting facilities here will refuse to
test any cylinder that does not have a US DOT (?) stamp.

I purchased a properly sized (for a DG or AS) US-style cylinder
from Eastern Sailplane (http://www.easternsailplane.com/)
a few years ago...

If you mean a permanently installed aircraft system that is part of
it's certification - I assume there wouldn't be any problem getting it
filled. Gliders use "portable" systems, which have different
requirements.

Find a mom and pop medical oxygen supplier. Tell them what you want and
describe your requirements. They probably have some cylinders sitting in
the back that they would love to get rid of. That's how I found one that
fit my LS-3a... probably similar size requirements to yours. They had a
bunch of different sized cylinders. I was able to get mine for a song
because it was an oddball cylinder. Had been hydrotested within the
appropriate time. You may need to get the valve changed to something that
will accept your regulator, etc.
YMMV,

hydrotesting requirement on steel cylinders. I was remembering something
about 10 years. I checked mine last night and found that it was hydrotested
in '97 so I took my cylinder by the supplier today to have it tested and was
told that it indeed is a 10 year test requirement for steel cylinders.
Perhaps it is 5 years on cylinders that are permanently installed in an
airplane, not just a supplemental "portable" steel oxygen cylinder.

requalification of cylinders). It's a DOT regulation, not FAA. if you have a
DOT 3A or 3AA cylinder it's 10 years; DOT 3 is 5 years. Try
http://www.myregs.com/dotrspa/.
Also, CFR49 is where it states that a non-DOT approved cylinder may not be
refilled in the US. Not sure about the status of a foreign cylinder (non DOT
approved) that is installed in a foreign built aircraft that quilifies for a
US airworthiness certificate under JAR 22. Best not to ask.

10 year hydro period for 3A and 3AA bottles only applies if there is a
star stamped after the most recent hydro date.
(b) DOT 3A or 3AA cylinders.
(1) A cylinder conforming to specification DOT 3A or 3AA with a water
capacity of 56.7 kg (125 lb) or less that is removed from any cluster,
bank, group, rack, or vehicle each time it is filled, may be
requalified every ten years instead of every five years, provided the
cylinder conforms to all of the following conditions:
(i) The cylinder was manufactured after December 31, 1945.
(ii) The cylinder is used exclusively for air; argon; cyclopropane;
ethylene; helium; hydrogen; krypton; neon; nitrogen; nitrous oxide;
oxygen; sulfur hexafluoride; xenon; fluorinated hydrocarbons,
liquefied hydrocarbons, and mixtures thereof that are commercially
free from corroding components; permitted mixtures of these gases
(see) § 173.301(d) of this subchapter); and permitted mixtures of
these gases with up to 30 percent by volume of carbon dioxide,
provided the gas has a dew point at or below minus (52° F) at 1
atmosphere.
(iii) Before each refill, the cylinder is removed from any cluster,
bank, group, rack or vehicle and passes the hammer test specified in
CGA Pamphlet C-6 (incorporated by reference; see § 171.7 of this
subchapter).
(iv) The cylinder is dried immediately after hydrostatic testing to
remove all traces of water.
(v) The cylinder is not used for underwater breathing.
(vi) Each cylinder is stamped with a five-pointed star at least
one-fourth of an inch high immediately following the test date.
(2) If, since the last required requalification, a cylinder has not
been used exclusively for the gases specifically identified in
paragraph (b)(1)(ii) of this section, but currently conforms with all
other provisions of paragraph (b)(1) of this section, it may be
requalified every 10 years instead of every five years, provided it is
first requalified and examined as prescribed by § 173.302a(b)(2),(3)
and (4) of this subchapter.

dealers, I sell a full carbon fiber wrap bottle that measures 13.5" long
(bottle only), 5.38" diameter, and only 3.7 lb. It's rated for 3000 psi and
holds 717 liters at that pressure (533 liters @ 2K). $595 includes a CGA-540
valve, pressure gauge and UPS ground to lower 48.
Note: I became a wholesale dealer for this size bottle only (I have nothing
else for sale - honest) out of desperation. I couldn't find anyone selling a
good bottle to fit the Stemme S10 that would maximizing O2 capacity and
still not stick way out into the cockpit. Most bottles that were short
enough, like MH's CF-480, were too narrow so didn't hold all that much.
Longer bottles, like MH's KF-022, are a safety concern for Stemme owners as
they end up alongside the occupant's head.
If you need one of these, please contact me privately for info.

I wanted a second cylinder for my 400. DG-USA quoted me $150, so I
ordered it. By the time I got it, with shipping, it was close to $400.
