Jim, Gary - did you guys read the following (FAA Order
8000.40D)?

1. It applies to Part 91 aircraft, among others (para
1)
2. It says the FAA Adminstrator has adopted 'the rules
and regulations
of DOT, RSPA, USCG, UL, MIL-SPEC, and applicable manufacturers
as
acceptable methods for controlling the hydrostatic
tests and life
limits of pressure cylinders' (para 4d)
3. It says 'pressure cylinders used aboard aircraft
should be
maintained under the same specifications prescribed
by the appropriate
regulatory agency and manufacturers if no other requirements
are
available.' (para 4e)
4. It says 'Cylinders which have reached their hydrostatic
test due
date cannot be recharged or installed until hydrostatically
tested.'
(para 6e)

This seems pretty clear - even if your oxygen tank
is non-DOT approved,
you have to follow the manufacturer's specs and you
have to have it
hydrostatically tested in order to use it in your aircraft.

I think you got it right Gary. Those 180 and 173 rules
are all about
transportation in commerce. However, most IA's will
still want to see a
hydro date if that bottle is in your glider during
your annual.

Yes, that was covered several posts back. FAA wants
the cylinder tested as if it were DOT approved which
is very reasonable. Getting a hydro on a non-DOT 02
cylinder is no problem.
