I've wondered about this in the past. The cited regulations deal with
packaging for transporting hazardous material in the course of commercial
interstate commerce. I would contend that when I fly with an oxygen tank I
am no more "transporting" oxygen than I am transporting my main wheel tire.
Do these regs really legally apply to gliders or other private aircraft?

Mind you, I'm not advocating ignoring the recertification times listed (I
have mine done), and I know that most FBO's won't fill a cylinder that is
out of date.

180.205 and 180. 209 are the ones you're looking for. 180.209 is the
chapter
with the number of years between hydro. There were some recent changes to
180.205, but not that you'd notice, bottom line on .205 is you have to
have
the cylinder hydro'd prior to re-filling.

I know it is out there someplace but I cannot find it, I always thought
it
was a DOT thing.
Anybody have the official link to where the cylinder testing intervals
are
defined?

Fly safe, have fun,
