SERVICING — SYSTEM DESCRIPTION
1. Description
A. General
(1) Servicing / Replenishing Fluid Systems
When servicing and replenishing the various systems, the mechanic or serviceman must be
very observant, always on the lookout for leaks in plumbing, frayed or broken strands in
visible control cables, security of all components and access doors and panels. Pay particular
attention to the following:
• Drip pans under accessories
• Fire extinguisher pressure gages
• Tire condition
• Tire slip marks
• Oxygen pressure indicator
• Hydraulic lines on all landing gear
• Access doors closed and secure
• Fuel stains caused by leaks from fuel tanks, plumbing or components
• All visible plumbing for leaks
(2) Identification of Tubing
A color coding system has been devised to aid the mechanic in servicing aircraft and to
facilitate identification of tubing of a particular system. This coding system consists of a series
of symbols and colors which, when placed in a certain order, will denote an aircraft system. In
addition to the combinations of colors and symbols, there is a warning symbol that is used
when contents of the line are considered to be dangerous to maintenance personnel. This
symbol is placed adjacent to the system symbol.
For further information see MIL-STD-1247.
NOTE: Use Line Coding Chart as an aid in identifying the different types of tubing in aircraft.
See Figure 1.
(3) Replenishing Data
Refer to Servicing Table below for information on replenishing the various systems and see
Figure 2 for applicable locations on aircraft.
