MAINTENANCE MANUAL
OXYGEN SYSTEM COMPONENT HANDLING.
Keeping in mind the effect of compressed oxygen on materials, oxygen system components must be
handled carefully. Ports on regulators. indicators, and other opened components must also be kept capped or
plugged to prevent ingestion of foreign material. Adjustments or modifications should only be initiated upon
approval of the FAA, Piper, or Scott Aviation.
REMOVAL OF OXYGEN CYLINDER. (Refer to Figure 35-5.)
- NOTE -
Replacement time for the recharge valve is every 5 years. If the
cylinder is being removedfor the 5 year test, it is recommended the
valve be removed and/or replaced at the same time.
The oxygen bottle, located behind the finished bulkhead in the baggage compartment. is secured to a
removable shelf mounted to each side of the fuselage. The tank is mounted such that the regulator-control
valve is on the left side of the aircraft, the same side as the recharge valve. A shroud also covers the regulator
end of the bottle to prevent leaks, should any develop, from filling the aircraft with oxygen. With this in mind.
a vent tube interconnects the shroud with the recharge valve fixture permitting any oxygen to vent overboard.
1. Remove the screws attaching the finished bulkhead to the fuselage bulkhead, and remove the finished
bulkhead.
2. It is recommended that when working in the rear of the aircraft, an appropriate tailstand be properly
attached to the tail.
3. With the immediate area clear of flammables (grease, hydraulic fluid, fuel), and oxygen system off.
connect a mask of tube to an outlet to exhaust any pressure in the system.
4. Remove the screws and loosen the clamps securing the shroud to the cylinder and regulator-control
valve.
5. Remove the spring clamp securing the vent tube to the cylinder shroud and disconnect the tube.
6. Carefully separate the shroud along the high pressure lines.
7. The high pressure fitting on the regulator-control valve incorporates a valve that opens only when a
line is connected with it. With this in mind, carefully unscrew the high pressure line until the pressure decreases.
and then remove the line. Disconnect low pressure lines as well.
8. Loosen and open the clamps securing the bottle to the shelf. Carefully move the bottle in such a way
the fair access can be made to control mechanism.
9. Disconnect the control cable. Be careful not to kink the cable.
10. Remove the tank from aircraft being careful not to damage the regulator-control valve.
