9. Make sure to check the oxygen lines for proper clearance as follows: (Refer to Figure 35-4.)
A.
Two inch minimum between oxygen tubes and all flexible moving parts of the aircraft (flexible control
cables. etc.). If enough space cannot be attained, protection from abrasion must be provided.
B.
At least 1/2 inch minimum between oxygen tubes and all rigid moving parts of the aircraft such as
levers and rigid control rods.
C.
Six inch minimum separation between oxygen tubes and hydraulic, fuel, and electrical system lines
and components.
(1). When the six inch requirement cannot be complied with, one inch is allowed as long as electrical
cables and other lines are supported at least every two inches; and, the oxygen tube(s) is protected by
rubber neoprene hose fastened in place with cable ties at the location the specific item crosses or is
near the oxygen tube(s). If an item is near the oxygen tube for a certain distance the oxygen tube for
that distance must be covered.
D.
A minimum of l/2 inch between tubing and structure adjoining the supporting clamp, as shown in
Figure 35-4, Sketch A.
E.
Where a tube passes through a grommet, the tube must not bear on the grommet in any way that might
cause cutting of the grommet in service as shown in Figure 35-4. Sketch D.
F.
While in service, items may receive vibrations causing them to come in contact with other parts of the
aircraft. With this in mind, low pressure tubing that is supported well enough to prevent relative
motion must have at least a minimum clearance of 1/8 inch from a projection (bolt, nut, etc.). Low
pressure tubing that cannot be supported well enough to prevent motion must have a minimum
clearance of 1/8 inch allowed after the maximum travel of the tube. High pressure lines are affected
similarly but require l/2 inch minimum clearances. Refer to Figure 35-4, Sketch B.
10. Perform any other required maintenance as directed in AC 43.13- 1A, Chapter 8.
11. Clean components as necessary per the following subject-paragraph.
CLEANING AND PURGING OF OXYGEN SYSTEM COMPONENTS.
— CAUTION —
CARE AND ATTENTION TO DETAIL ARE ESSENTIAL TO PREVENT
C O N TA M I N ATION OF COMPONENTS BY OIL, GREASE, WATER, OR
FOREIGN MATTER. COMPRESSED AIR USED IN CLEANING AND
FLUSHING TUBES MUST BE CLEAN, DRY, FILTERED (OIL FREE) AIR
ONLY.
Three methods are recommended for cleaning oxygen system components as follows:
1. Method 1.
A.
Vapor degrease affected part(s) with trichlorethylene.
B.
Blow part(s) dry with a stream of compressed air, or dry nitrogen. Refer to previous caution.
2. Method 11.
A.
Flush with naptha conforming to specification TT-N-95.
B.
Blow clean and dry off all solvent with clean, dry. filtered air. Refer to previous caution.
C.
Flush with isopropyl alcohol.
D.
Rinse thoroughly with fresh water.
