PUBLICATIONS.)
CAUTION: WHEN REFILLING ANY OXYGEN CYLINDER MAKE SURE TO USE ONLY AVIATION
BREATHING OXYGEN AS SPECIFIED IN MIL-O-27210C. THE MOISTURE CONTENT OF
AVIATION OXYGEN CANNOT EXCEED 0.005 MILLIGRAMS OF WATER VAPOR PER
LITER OF GAS AT 70°F (21°C) AND 29.92 INCHES OF MERCURY (760 MM HG.).
The following provides supplemental information for the servicing of the oxygen system. Major repairs to
the oxygen system should be accomplished by an approved shop.

iption and Operation ( See Figure 1.)
WARNING: DO NOT USE GREASE OR ANY TYPE OF GREASE FITTING ON ANY OXYGEN
SYSTEM. WHEN WORKING WITH AN OXYGEN SYSTEM MAKE SURE HANDS,
CLOTHING, TOOLS, AND IMMEDIATE AREA ARE FREE OF GREASE.
A fixed oxygen system is available in 6XT airplanes only, as an option. The major components for this
system are manufactured by Scott Aviation. Accordingly, Scott Aviation, as well as Piper Dealer Service
Administrators (DSA’s), should be contacted for information / procedures not covered herein.
The oxygen system cylinder is installed in the tailcone, behind the baggage compartment, and is
connected to an external recharge valve mounted to the left side of the fuselage, aft of FS 222.437. The
low pressure (L.P.) feed line for the outlets is routed to the right side of the fuselage and then up into the
cabin overhead. It joins the outlets’ distribution manifold at a tee-fitting on the right rear passenger outlet.
The PULL-ON regulator valve control knob and pressure gauge are installed in the pilot’s instrument
panel below, and slightly to the right of, the control wheel. The control knob actuates a cable routed
through the center cabin overhead and attached to the oxygen system cylinder regulator valve. The
pressure gauge is fed by a high pressure line routed from the oxygen system cylinder along the right
side of the fuselage and then up into the center cabin overhead where it joins the control cable and the
two are then routed down the windshield centerpost and into the back of the instrument panel.
NOTE: Oxygen cylinders are identified by the ICC or DOT identification stamped on the cylinder. The
lightweight cylinder of composite construction (DOT E8162) installed in these airplanes must be
hydrostatically tested every 3 years, and the service life may not exceed 15 years. The month
and year of the last test is stamped beneath the ICC/DOT identification.
