TM 1-1500-204-23-6
NOTE
•
Store cells in a cool, dry area, free from drafts, dust, and ozone, and out of direct
sunlight or direct contact with the ground
•
Stack crated cells on widest side of crate, never on end, and not to the extent that
crushing of lowest crate will result
•
Arrange cells in storage to ensure use of oldest units first.
c.
Oil Cell Identification. An oil cell is a form of oil tank that has self-sealing capability. It can be identified by a
compound covering the interior walls. This compound will seal the oil cell if it is punctured by a projectile. Self-sealing
oil cells are repaired in the same way as self-sealing fuel cells. However, greater care must be taken in cleaning the cell
in preparation for repair work. Refer to TM 1-1500-204-23-3, Chapter 3, for additional information.
d.
Oil Cell Storage. The applicable aircraft maintenance manual shall be used for specific storage procedures. The
following general procedures apply to all oil cells:
(1) Drain all oil from oil cell.
(2) Disconnect oil lines and tubing.
(3) Clean oil tank with appropriate solvent.
(4) Drain solvent.
(5) Dry tank with filtered compressed air.
(6) Cover inside of oil cell with lubricant.
(7) Replace filler cap.
3-5.Shock Absorber and Elastic Exerciser Cords. Identification, inspection, testing, and storage of shock absorber
and elastic exerciser cords are explained in the following paragraphs.
a.
Cord Identification. Colored threads in the outer cover are used to indicate date of manufacture. The color code
for threads is given in table 3-1. Bungee and shock absorber cords have two threads to indicate year and one thread to
indicate quarter. Elastic exerciser cords have three threads to indicate year and one for quarter. Elastic shock cord,
used in some compass mounts, is covered with solid black braid with no colored thread to indicate date of manufacture.
Although these cords do not have a limited shelf life, they must pass the elongation test below before installation.
b.
Cord inspection. All cords installed in aircraft shall be visually inspected at each intermediate and periodic
inspection. Any cord that shows irregularity in diameter must be replaced. Cords found to be over 5 years old will not be
considered serviceable.
(1) Tagging.
Cords in stock shall be inspected and tested every 6 months as specified below. At time test is
made, a serviceable parts tag shall be affixed to the spool or cord as follows:
INSPECTED ................................ .........
DATE ................................ ....................
ACCORDING TO TM 1-1500-204-23-6
TO BE REINSPECTED AND RETESTED 6 MONTHS FROM DATE HEREON
NOTE
Sections of cord shipped to service activities shall have a duplicate tag affixed to
provide information for reinspection date.
(2) Methods of inspection. Cords in stock at all activities other than depots shall be visually inspected for
irregularities in diameter or other evidence of deterioration and to see that serviceable parts tag is attached as specified
above.
(3) Test requirements. Cords that fail to meet test requirements shall not be installed on aircraft, but will be
made available for use on ground equipment or for other uses
